How to Increase Your Home's Zillow Zestimate

I have always had a keen interest in real estate valuations and have learned how Zestimates and Trulia valuations are calculated.

Modern home buyers look to sites like Zillow and Trulia to gauge what properties are worth. Make sure your home's valuation is as high as it should be!

Modern home buyers look to sites like Zillow and Trulia to gauge what properties are worth. Make sure your home's valuation is as high as it should be!

Before listing a home for sale, many sellers ask themselves how they can increase their home's Zillow Zestimate. The online real estate marketplace is more popular than ever, so whether it is fair or not, most modern buyers are going look at a home’s Zestimate to gauge its true value. Although there are other independent measures of a property’s worth, including valuations by Trulia, Zillow’s rival, Zestimates are considered by many to be the most accurate and reliable expression of a home’s value.

What many sellers don't know is that increasing a home's Zestimate is not difficult. Zillow often lacks accurate, up-to-date information about a property, which can cause the site to calculate a Zestimate that is lower than it should be. Luckily, it's easy to add missing information to your Zillow listing and potentially increase your home's Zestimate.

5 Ways to Boost Your Home's Valuation on Zillow

The power to increase your home's Zillow Zestimate is in your hands. The first thing you need to do is go to zillow.com, create a free account, and look up your address. Once you have found your home on Zillow, claim it as yours. Once you've claimed your home, you are free to update the listing with the various amenities within and around it, add a detailed description of what you like about it, and even provide an estimate as to what you believe it is worth. Once you've claimed your home, follow these five guidelines to ensure your Zestimate is as high as it deserves to be.

1. Make Sure You Check Off All of the Relevant Amenities

Read the list of amenities that Zillow provides and carefully and check off all of the boxes that apply to your home. Be sure you do not miss anything, as each amenity will factor into your home's Zestimate. You can describe the amenities you've checked off in more detail in the description of your home.

For example, Zillow has a checkbox for attics. If your home has an attic, check this box off and describe the condition of your attic in detail in your home's description. You could say something like "The insulated attic provides ample storage space and can be accessed easily with a pull-down ladder."

2. Tailor Your Description to Your Buyer's Needs

In the description of your home, think like a buyer and tailor your description to suit a buyer's needs. For example, if you assume most of your potential buyers will need easy access to commuting options to get to work, then emphasize how convenient your home is for commuters.

You could say something along the lines of "The house is only five minutes from the local train station, and a commuter bus has a stop approximately one-quarter mile away." Other than that, the description should emphasize things that buyers look for in a home, such as remodeled bathrooms, stainless steel appliances, stone countertops, and a fenced-in yard. It's also a good idea to use terms like "move-in ready" or "in a great area for families" if these statements are applicable.

If your home is close to a bus station, gets lots of natural light in the afternoon, or has hardwood floors, be sure to say so in your description!

If your home is close to a bus station, gets lots of natural light in the afternoon, or has hardwood floors, be sure to say so in your description!

3. Get Creative With What You Like About Your Home

In the "what you like about your home" section on Zillow, describe amenities and other things about your home that may not be readily apparent to potential buyers. For example, if there is a park half a block away or a beautiful view from your home, make sure you emphasize it when describing what you like. Buyers with children may like the fact that there is a park within walking distance. Other buyers may be looking for a home that has a nice view instead of a window that faces the back of someone else's house. Get creative and mention any useful resources in your area. Proximity to things like shopping and entertainment centers can help sell prospective buyers on a home they are considering.

4. Be Realistic About What Your Home Is Worth

If you are going to put a value on Zillow in the "what you believe your home is worth" section, make sure it aligns with your asking price. You do not want to list your home for sale at a price that is higher than what you publicly state it is worth. Be realistic—many people naturally tend to think their home is worth more than it actually is. Take a few moments to see what homes of similar style, condition, and size have sold for in your area recently and formulate a fair and realistic value.

5. Avoid Exaggerations

Be honest when updating your home's Zillow information. While it is tempting to exaggerate certain amenities, any untruths could turn off potential buyers (or even lead to a lawsuit if someone purchases your home and finds the information you provided to be inaccurate). If you have a nice house, describing its advantages accurately should be all you need to do to attract buyers. Keep in mind that Zillow’s Zestimates are not updated instantly, so it could take some time before the changes you have made are reflected in your home's Zestimate.

Why Is It Important to Update Your Home's Zillow Information?

While there are no guarantees that adding additional information to your home's Zillow page will result in an increase to its Zestimate, it certainly cannot hurt. If features that exist in your home, such as a fenced-in yard or hardwood floors, are not selected in Zillow, the site will assume you do not have them, and your Zestimate will suffer.

You'll also want potential buyers to be able to see all of the amenities your home has to offer. While the description of your home and what you like about it may not directly affect its Zestimate, they will certainly impact potential buyers’ decisions about whether to consider your listing in their home-buying process.

It is also important to list your home as "for sale" on Zillow once you have updated the listing information. Many people in the market to buy a home will "fly over" a neighborhood they are interested in moving to. When you list your home as "for sale" with Zillow, a red house symbol appears over your property on their map to alert buyers that it is available. Buyers can then click on the red home symbol to see the Zillow page that includes the detailed information that you've provided. By keeping your listing up-to-date and thorough, you increase the likelihood that prospective buyers will form a positive opinion of your home and contact their realtors to view it in person.

Questions & Answers

Question: I had a Zestimate of $360,000 and listed my home on Zillow's Make Me Move for $400,000. Four days after my listing, the Zestimate fell to $300,000. This could cause serious problems if I decide to list my home for sale. We paid $300,000 for the home over 6 years ago and have put $80k into renovations and upgrades, so I don't think $400k is an unreasonable ask. Is there anything I can do to get Zillow to recognize this?

Answer: Make sure you claim your home and update all of the information, particularly any information that has changed due to your recent renovations and upgrades. That is how Zillow will become aware of them and potentially adjust the Zestimate.

Putting a Make Me Move price in probably prompted Zillow to look at comparable home sales in your area, which is the most likely explanation of your Zestimate drop. Take a look at which home sales they are using to compare your home's value as part of the Zestimate.

Question: My house estimate on Zillow went down $100k suddenly for. The house is not for sale. And this sudden drop only happened to my house in the neighborhood. What could be the reason?

Answer: Wow! I'm sorry to hear that the Zestimate for your house went down by 100K. What is that percentage-wise based on the overall value of your home? I would look into if there have been any recent sales in your area that have been below market and are being used by Zillow to determine the value of your home. I don't know why it only happened to your house. It could be that the other houses are valued based on other comparables based on their value and features, or it could be that they will soon experience a similar percentage drop.

Question: We followed your instructions and every time we added something to zillow, they decreased our value. It is now so low it is affecting the sale of our home. We have emailed them and they refused to look at a bank appraisal or anything we had to prove the value of our property. Everytime we emailed, our zestimate got decreased the next day. It is now $30,000 below a bank appraisal that was done 5 years ago and we have added $20,000 in improvements. What do you suggest we do now?

Answer: Adding information to Zillow that makes your home more valuable shouldn't decrease the Zestimate. For example, if you have hardwood floors, but Zillow didn't know that, then adding that info should be a net positive for your Zestimate. I would look into whether there are other factors that are affecting the value of your home, such as comparable sales that they are comparing your home value to in order to calculate the Zestimate. Comparable sales are used by real estate agents to get an idea about what a home is worth, so I would assume Zillow puts a lot of weight into those numbers. Get a professional real estate professional's opinion regarding what they think your home is worth based on comparable sales and their knowledge of the local market and the improvements you have made. The good news is that it is not uncommon for homes to sell above the Zestimate, sometimes substantially above it. You just have to impress a buyer enough to get them to pay your asking price. If your renovations are impressive and you work with a good realtor who knows how to sell homes in your area, you have a good chance of getting your price.

For my home, the comparable sales don't always seem fair or consistent with what type of home I have, and I think it's worth more than the Zestimate, but I can't do anything about what sales they are using to compare my house to in order to come up with their Zestimate. Some areas that have high property have been hit quite hard by the recent change in federal tax law that limits how much State and local taxes one can deduct from their Federal taxes, and it has caused property values to fall as it has taken buyers out of the market or made people bid on lower-priced properties, since the cost of owning a home has essentially gone up in areas hit hard by the State and local tax deduction change. The area I live in has been hit by this tax change, with prices falling slightly over the past year and Zestimates falling as well.

Remember, you just need one buyer that really likes your home and is willing to pay up for it. The problem is finding that buyer. That's why finding a good real estate agent, who really knows your area and is committed to selling your home is extremely important. They can get the right people into your home to see how you improved it and understand that its worth what you are asking to sell it for. Don't hire a friend who is a real estate agent that works five towns over because you want to do them a favor. Hire someone in your town who has a really good reputation and the connections with other local agents to sell your home.

Question: My neighbors property just was put on the market. I checked the zestimate and it was 625,000. She listed her property for $1.1 million and zillow even had on the zestimate. 4 days later the zestimate miraculously is at $1.1 million. Almost $400,000 more than my house which is larger, with a larger lot and 18 years newer. Why are there these price disparities on Zillow?

Answer: I'm not sure why Zillow suddenly decided to value your neighbor's home at $1.1 million. I have seen such dramatic increases in a Zestimate in the area I live in, but it occurs when a house has not been sold in many decades or has been completely gutted and renovated, and then is listed for sale at a much higher asking price than what it was previously worth. Was the home renovated recently? Perhaps there were some recent comparable sales that Zillow just factored into the Zestimate for your neighbor's home? It's hard to say, but it would certainly be great for your home value is this home sold for anywhere near $1 million because Zillow will factor that sale into Zestimates for similar homes in your area.

Question: The initial price of our home on Zillow.com shows we paid $125,000. However, that was the lot price. How do we fix this?

Answer: First, check your local or county tax records to see if they have updated them to include your home value. Zillow gets their information from these sources. It may take some time for the tax records to be updated (several months in some areas). You can also notify Zillow to make them aware of the situation. It will only help if they are aware of it.

Question: I purchased a house that was brand new 25 years ago. It was never listed or sold. I have added new granite countertops, subway backsplash, hardwood floors, carpet, ceramic tile, new s/s appliances, new HVAC system, newly painted interior, upgraded fixtures, etc. Homes the same size are selling the 170s to 180s with no upgrades. But because mine was never listed or sold, Zillow lists my house 40,000 below the average price for the area. I opened an account and listed all the amenities. What else can I do?

Answer: If you just opened an account with Zillow, claimed your house, updated the facts about your house to help Zillow better understand what your house has as far as features, then you need to give them some time to digest these changes. They update Zestimates on a monthly basis. However, it could take several months for them to fully reflect the changes you made. Also, check out the comparable sales that they are using to value your home. Is there anything that could be hurting your home's value, such as its location? The same home could realistically be valued $10,000s less or more based on location. For example, being on a busy street can knock dollars off a home's value, while having a view of a lake on a quiet street could do the exact opposite and boost a home's value versus comparably sized homes.

Question: My neighbor's house across the street is the same floor plan but does not have a finished basement (our house does). Why is their Zestimate ~ $80K higher than our house? I do not see any differences in the Zillow features and amenities.

Answer: Your question is certainly a head-scratcher, as it certainly makes no sense for your house to have a Zestimate lower than the one across the street when you have a finished basement. Make sure you claim your house on Zillow and update all of the information, including the fact you have a finished basement, One interesting quirk about real estate, at least where I live, is that a finished basement that is entirely underground (not a walkout basement that has ground-level access in the back) cannot be included in your house's total square footage, so keep that in mind when you are updating your square footage. If all else fails, contact Zillow and ask them. They probably will just say they rely on the Zestimate algorithm but it's worth a try and may cause them to take a closer look at your house's valuation.

Question: Will listing remodeling and updates on my home increase my property taxes? Home is currently off the market.

Answer: In most jurisdictions, simply remodeling shouldn't affect your property taxes right away. However, if you have a tax reassessment done and an inspector sees the improvements they will likely increase the value of your home, thus increasing the property taxes on your home.

Question: Zillow did not put a value on my 600-foot workshop building. Since this is a building worth $50,000, it should be added. What should I do?

Answer: Contact Zillow. This is an example of one of those quirky things that the Zestimate is not good at picking up on, i.e., adding the value of a property. They have no idea what condition it is in or if it is a functional building, so they may be either ignoring it in the Zestimate or giving it a valuation that is much less than the value it actually adds to your property.

Question: If my agent didn't make the appraisal of my home, would that decrease my chances of getting a good appraisal or Zillow Zestimate?

Answer: An appraisal is best done by a professional appraiser who does not have an interest in the sale. An agent can run comps and provide you guidance, but that is not an appraisal, it’s just guidance.

Question: My home is brand new and the Zestinate is 80k below the appraisal. Why is this?

Answer: Zestimates do not usually take into account appraisals since most are not part of the public record. Zillow will have to digest data regarding what similar homes are selling for in your area to make an adjustment to the Zestimate for your home. If they sell for close to your appraised amount, then theoretically Zillow should adjust the Zestimate higher.

Question: The Zestimate on mynewly listed home has dropped by $10,000 in 3 days. What would be the reason for that?

Answer: I'm not sure, but it's most likely because Zillow did a price comparison when your home listing appeared and found comparable homes that sold for prices that brought your home value down by $10,000.

Question: Before I posted my home for sale my zestimate was $780,000 (that was 11 a.m. this morning. Once I posted my house for sale at $759,900 the zestimate went down (that was 11 a.m. this morning). Once I got the email that my home was posted for sale the zestimate went down to a little below my asking price. WHY?

Answer: I'm not sure about your specific situation. I assume Zillow take a new look at a home when it is listed for sale and adjusts the Zestimate based on what they find. It may have been months since they last took a look at comparable sales, but now with it listed for sale their Zestimate program was prompted to do a comparison of your home's value versus similar homes that sold in your area.

Question: My house has 6 bedrooms 4 baths, 2810 sq feet, 7500 sf lot, built in 1991. My neighbor has 3 bedrooms 1.5 bath, 960sf, 7500 lot, built in 1979. Rent zestimate shows my house as $2600 and my neighbor as $2500. Why a difference of only $100 between these 2 homes? Zillow estimates the value as $829,000 and my neighbor as $529,000.

Answer: Sounds like you have a nice house! Zillow is obviously wrong about the rent Zestimate. A house that is 3X in size and is similar condition should command a lot more rent than a smaller one. Probably not 3X times in rent, but considerably more than the smaller house. Just look around local rent listings to see what your house should rent for. Rent prices are a very localized thing based on neighborhood, access to transportation, and of course demand.

Question: I bought my apartment 1 year ago. The entire apartment has been refurbished, Zillow shows asking price of 20k less than when the neighborhood has not changed. Why the drop of $20k in one year?

Answer: I can't answer why a specific property dropped in value by 20K in one year. It could be related to comparable sales of similar apartments in your area that dropped or it could be a general drop in your area due to the federal tax law change. In my state, home values have been struggling since the high property taxes now have a cap regarding how much of them can be written off on federal taxes. It's making home ownership cost more and removing some buyers from the market.

To look up the comparable sales that make up your Zestimate, go to your apartment's Zillow page. Then go to Inside the Zestimate that is below your Zestimate. Then click on Comparable homes to see which recent property sales Zillow is using comparable sales as part of their Zestimate calculation. Also, click on Local tax assessments to see how Zillow is using local tax assessments to value your home.

It sounds like your apartment is one of those properties that Zillow has a hard time valuing since you recently renovated the interior, but they may not recognize that in their Zestimate calculation. Make sure you update your property description to reflect the renovations. Also, there's no reason why your property can't or won't sell for above the Zestimate if you demonstrate to buyers that walk through that it's worth more than what Zillow says it's worth. I see homes sell above their Zestimate all of the time. It still comes down to finding a motivated buyer that likes your home and is willing to pay for it.

Question: How can an appraiser value my home almost $20,000 less than Zillow and Redfin?

Answer: It is possible that Zillow and Redfin are making assumptions about the features associated with your home, while the appraiser with their first-hand look did not find these features. They could also be using different sales to calculate their comps. Keep in mind that appraisers tend to be conservative by nature, especially after the financial crisis of 08/09, which called some of the actions of those in that line of work into question.

Question: My zestimate is actually my assessment for property tax purposes only (which is always lower than market value) and therefore $40,000 less than my asking price; what can I do?

Answer: If you go to the Owner's View for your home, Zillow explains how they arrive at a value for your home using the local tax assessments. This number is adjusted based on the average that's comparable homes are selling for in your town versus their assessed value. It appears to be an automatically generated number (the adjust your home's value by a percentage upwards or downwards based on comparable sales prices versus assessed values). This number is just one component of the Zestimate. Look at comparable sales prices also, as this affects your Zestimate. It may provide more insight into how they arrived at the Zestimate 40K below your asking price.

Ask what you think your home is worth. A home in my area just sold for 550K, which is 87K above the Zestimate before the sale. It ultimately comes down to supply and demand, as well as finding a motivated buyer that is willing to pay your price. In my area, there aren't many large homes with 4 bedrooms that have adequate space for larger families, so when the owners listed their large 4 bedroom home for 550K they got the price they wanted despite Zillow's estimate of what their home was worth. Limited supply and motivated buyers looking for this type of home.

Question: We had an official appraisal for an equity loan, and it is $40,000 more than the Zestimate. How do I get the Zestimate increased?

Answer: Besides the suggestions I made in this article, the only other thing you can do is try to contact Zillow directly. I'm not sure if they can take a private appraisal into consideration, but it's certainly worth trying. Ultimately, if similar homes in your area start selling for prices close to or above the appraised amount for your home, then the Zestimate should eventually increase to that level.

Question: I had a fascinating Zillow Zestimate change in 24 hours, that readjusted in 24 hours. I went onto my Zillow owners page to delete all the photos (for privacy) except for one overhead shot. As soon as I did that, the Zestimate went from $513k to $489k. I didn’t change any other factors. I reloaded the photos and today it’s back to $513k. Is it true that there’s a “visual” algorithm on Zillow that detects “pleasing” spaces in and around the house?

Answer: Yes, it is true. In June 2019 Zillow announced it has a new algorithm that uses photos to help decide the appeal and worth of a home.

Question: I have had a recent professional appraisal, can I add it to Zillow?

Answer: I don't think there is any way to add a professional appraisal of a property's value to Zillow. Real estate appraisals are private matters between the person requesting the appraisal and the company that performs the appraisal.

Question: Why does it seem WATERFRONT is not an issue when it is a huge issue?

Answer: I'm not sure what you mean by "issue?" Waterfront properties usually are more valuable than ones that don't have waterfront access, even if a home is the same size and with the same features as ones that do not have access to water (like a lakefront). People will pay more for waterfront access and they will also pay more for views of water, which may or may not be reflected in the Zestimate. This is an example of where Zillow's Zestimate can be lacking. If it doesn't pick up on the effect that a body of water has on nearby properties, it's going to spit our erroneous values

Question: Our house value is $113k. Other homes in same size/age are $165k-$189k. Ours was renovated top to bottom 24 months ago. Most of the ones for sale nearby have not and still have appliances and carpet from the 1970-1980s. I have updated everything possible. Any suggestions on how I can have the value raised?

Answer: Make sure you claim your home and update your home's info on Zillow with your current renovations. That should help. Also, take a close look at the homes that they are using as comps to value your home. Perhaps the similar nearby homes are in a different school district or there is some other factor that values them higher? In the long run, the comps that value your home along with the updated info you provide should cause the Zestimate to be adjusted higher.

It is true that Zillow tends to change its Zestimate based on a recent property sale price. Whether that's fair or not is debatable since a sale is an indication of a property's true value in many instances. However, that is not always the case. There are plenty of homes sell for below market value due to seller circumstances in which they have to sell immediately and are willing to accept below market value offers. Over time, Zillow should adjust the Zestimate to what the true value of a home based on comparable sales ("comps") and other factors.

Rajarshi on May 02, 2019:

I bought a house listed for $250,000 - with a Zestimate very close to that. I bought it for $230,000 and the Zestimate immediately dropped. I find Redfin and Trulia more reliable and stable.

Tina on April 23, 2019:

Thank you, John. I am grateful we have a good realtor. Zillow gave us a typical answer about their algorithms without explaining the sudden 10% drop. Very unfair and disappointing. Thankfully Trulia shows the original price we could direct people to.

John Coviello (author) from New Jersey on April 22, 2019:

I'm sorry to hear that Tina. You can drill down a bit to see what comparable sales (comps) they are using to value your home on Zillow. Go take a look at that. It's possible that a similar sized home with similar features sold well below market and pulled your house's Zestimate down with it. That's not fair at all because there are many reasons why homes sometimes sell below market value since buyers are sometime desperate to sell for various reasons. Keep in mind that realtors will do their own home valuation based on comps. See what a professional relator has to say about what they think your house worth.

Tina on April 21, 2019:

Hello! Our house Zestimate went down within a day from $424K to $382K, a 10% loss!! How could this happen? My husband updated the written description of our home three days ago in preparation for the sale to make it more appealing. Other than that, we have no idea what might have changed to justify this kind of price drop- this is so upsetting as we are ready to put the house in the market!

John Coviello (author) from New Jersey on August 26, 2018:

Jessica - I don't know your specific circumstances, but Zestimates can be somewhat volatile. I've seen mine bounce around from month to month based on comp sales I assume. Give it a few months to see if it's regained the 12K loss. It could also be reflecting a turn in the real estate market with interest rates moving higher and some states being affected by the federal tax law changes that limit state and local tax deductions.

Stefanie - I'm sorry to hear that. Look into the finer details regarding the comps they are using to value your home. If you dig down into your home's Zillow pages, you can find that information. It may reveal some features that are causing the difference in valuation between your home and similar ones.

Jessica on August 21, 2018:

Why would my Zestimate have dropped 12000 in the last 30 days?

stefanie on August 13, 2018:

I think zillow is terrible. It has my home valued approx.$80,000 less than other homes similar to mine have sold for. I believe it is going to cause me problems in selling my home. I contacted them and they said there was nothing they can do about it.

John Coviello (author) from New Jersey on March 23, 2018:

I agree Marina that the Zestimate can be problematic and inaccurate. As I pointed out in this article, it overlooks some of the things that add value to a home. If they are comparing single-family homes to townhomes, then that is certainly problematic, since townhomes often have association fees and a lack of open space (like a yard), which can negatively affect a home's value.

But, the reality is that many people (for better or worse) use the Zestimate as a gauge of home values, so everyone might as well try to increase their Zestimate as best they can. Ultimately, it is just once valuation measurement that should be considered, among many others. I think a well thought out price comparison by a licensed Realtor is the best method to truly gauge a home's valuation.

Marina Epsteyn on March 19, 2018:

I believe this website caused harm to the buyers and sellers. The problem is that most of consumers are not RE professionals and do not understand the difference between the actual appraisal and Z estimate. Zillow estimates are inaccurate and, thus misleading. I looked at my home and found that Zillow uses townhouses for the comparable of my single family home, this is unprofessional and unethical! I also found, that exactly the same model home in my subdivision located 0.2 ml distance from my house, is showing absolutely different value and trends. No more comments.

Glenn Stok from Long Island, NY on December 17, 2017:

This is a useful article. I never thought of doing this before. Even though I’m not selling my home at this time, it’s still beneficial to keep the Zillow listing up to date. And as you said, to also include emenities that can provide a more accurate Zestimate.

Andrew M Merkel on January 22, 2017:

Zillow estimates are terribly inaccurate. The algorithms which they use in their software program are too heavily based upon tax historical records from the local tax authority. Unfortunately, what is not taken into consideration are various homeowner tax exemptions for individual properties, particularly in California, where tax bases are reduced to particular awards of exemption. This often occurs in the case of military veterans who may receive an exemption for a disability.

Zillow's algorithms do not adjust for this and, hence, cast a much lower value for a property accordingly. Zillow, thus needs to get ahead of the curve and offset their lowering a property valuation estimates based upon raw tax information.

Don't hold your breath.

A second major flaw is that Zillow does not use the most current records for making comparative sales of homes in a neighborhood. It is common knowledge by appraisers that comp sales generally should be within a half mile radius and have within the last 3 to 6 months...the most recent being applicable.

I have seen numerous examples of homes closest to a subject property and very recently sold being ignored by Zillow's algorithms and replaced by homes that are more than a mile away and as with sales dates more than a year old, and this in a prescribed tract of homes with 5 models and all built in the early 60's.

Best to hire an appraiser to get a SOUND EVALUATION.

The Zillow estimates are subject to wild fluctuations and manipulations by the Zillow software. Further, the more information about upgrades to a property which are added to a properties information are worthless in increasing the value of a Z estimate.

John Coviello (author) from New Jersey on January 04, 2017:

Cynthia,

Last I checked, there is no way to add a bathroom remodel to your home's Zillow profile. If you built a new bathroom, that could be added to your profile, which would likely increase your Zestimate, since this estimate is based on things like the number of bathrooms in a home and how it compares to similar properties.

For those that have bad experiences, like Sharon, it is possible that Zillow was making assumptions about your home that were skewed to the positive and once you updated your information it took into account the actual situation that is not necessarily as positive as they were predicting it was. Another thing to keep in mind is to give it time. I've seen the Zestimate go through gyrations after changes to a home's profile is made, and eventually rise.

Just check similar homes in your area to see if your Zestimate makes any sense. Sometimes it does not make sense, as Zillow seems to miss some of the less tangible aspects of a home, like a view or other amenities that affect property values.

I've just remodelled my bathroom. How do I add that fact to my zestimate?

I updated my home's information, checked off amenities, etc., and the Zestimate dropped by $10K! Completely inaccurate and doesn't reflect any updates at all. Thank goodness most buyers understand the Zestimate is nonsensical.

I've seen zestimates skyrocket just as soon as a house goes up for sale, the RE agent doesn't like the true zestimate, so they up the value substantially which is about what the new asking price is.

It looks as though it took 3 months for the updates I made to the Zillow listing for my home to be reflected in my Zestimate. I made the updates in Jan 14, and just now in Apr 14 my Zestimate spiked higher by $11,000. I looked at houses around me to see if it was an area-wide adjustment higher, and that does not appear to be the case. It appears that Zillow took my updates into consideration and adjusted the Zestimate higher after I added more details about my home and property, as predicted in this article.

If you are thinking of selling your home anytime soon, it would be a good idea to learn as much as possible about Zillow's Zestimate, because like it or not, many home buyers use it as a measuring stick regarding a home's actual value. It can be frustrating if one's home gets a low Zestimate. But, as I point out in this Hub, there are things that can be done to increase one's home's Zestimate. I wonder if those that are upset about their home's Zestimate have done anything to fill in the blanks with Zillow, so Zillow can properly value their home?

Personally, I've found Zestimates to be very close to the fair value of homes in my area. Trulia, by comparison, provides higher home valuations that are appealing to home owners and sellers, but do not often reflect what homes sell for (which is usually quite close to the lower Zestimate).

Thanks for reading!

I hadn't heard of a Zillow Zestimate before.
