I believe the Zestimate is based on the past history of sales on the particular home. Zestimate is, of course, only an estimate - and I am sure there is a formula they use for how much a home increases in value each year, based on the location of the home. Sometimes, these estimates are way off - but this is usually because of poor information on the home, i.e. when homes are "refinanced", this information can be shown as a "sale" on the home.

You can learn more about Zestimates here: http://www.zillow.com/howto/DataCoverageZestimateAccuracy.htm
If you reply with the address I'll try and explain how we came up with the Zestimate.

Yes...I'm very curious as to how they came up with the Zestimate. Why is my home showing 50,000 less than my two next door neighbors? This I've got see.

Your home has a lower tax assessed value than the others by 30 thousand dollars, which does have an effect on Zestimate calculations.
You home has a tax assessed value of $332,200 - http://www.zillow.com/Charts.htm?chartDuration=5years&zpid=38579949
7301 - assessed value is $361,00 - http://www.zillow.com/Charts.htm?chartDuration=5years&testAds=false&zpid=38579948

That is incorrect and must be years old. My assessed tax is 391,000
Maybe you should inform the county as to give me some relief from my taxation? The bottom line is I hope the county get it's information from your site. If so...you can zestimate my home at 200,000. ;)

Zillow is so screwed up!!! They have my house listed as being built in 1969...it was built in 1991....BIG DIFFERENCE!!! It also does not have the lot size correct...we have 2 lots (the house is on one...and we own the one right next to it!) So...it is on 2 lots!! I am very frustrated with their website!!

Well drew, you're right. This year my assessed value is 332,000. Next year shows 391,500.

Okay... so people that run zillow are not appearing very bright. How's that?
My house is 2100+ sq feet, on a 10K+ lot with a pool, travertine flooring, granite counters, 5 bed, 3 bath, etc.
My neighbor across the street is smaller lot, 980 sq feet house, with no upgrades (not pretty inside at all)....
Yet our 'zestimates' are within $5K of each other?!?! That doesn't make sense to anyone, is there anyway to get my house off of Zillow until you all learn how to assess a value more correctly?

We don't remove houses due to everything being a matter of public record.
Please note that Zestimates are not the final word regarding a homes value -- they are a starting point. We'll improve our accuracy over time as we add additional data and improve our algorithms, but no AVM (automated valuation model) will ever be 100% accurate.

It's funny how this entire forum is people complaining and giving specific examples about how bad the "Zestimates" are, yet this joke of a site keeps sticking to them or hiding behind "it's just a starting point"... I hope someone files a class action suit, I really do.

Like many have already stated there is a major problem with your estimates. We live in 94040 and purchased our home in 1980. 50-60% of homes on our street and two streets near us (similar neighborhood with lots in excess of 9500 sq ft - our lot is over 10,400 sq ft) have been sold within last 5-7 years reflecting better price estimates. Some of these homes are smaller than our home yet the estimate is much higher.
Also, in our area it's not the house, but it's the lot size that makes the difference. Many people purchase homes near us just to get the lot, demolish the house and rebuild a new one. Yet, I see homes on much smaller lots going for much higher estimate because of the recent sales within last 5-7 years.

What a joke... I just looked at my comparables and they have condo's in my comps.... I live in a house with about a 10K sq foot lot and you're putting condo's in my comps?!?! What a joke!

To zillow employees, it sure seems that there are alot of unhappy people out there. I think I read where one employee stated that the algorithim needed to be adjusted. This is what you get when you use automated processses, but I understand the need for such a high volume of homes. I also read that zillow is going to be taking into consideration the owners facts into their zestimate. Let's hope they do.
As things stand today, how about we just agree that zillow's zestimates are usually far off the mark? Starting point? Hmmm....I think not. If I ever decide to sell, I am truly hoping any potential buyer doesn't come out me with all the current zillow data. I'll just laugh at them.
For example with my property, my neighbors have a 50K increase over my home zestimate. I'm thinking it might be that small 4th bedroom they have. But they also don't have the view "money shot" that I do, property size I do, or their homes haven't been built with the quality components that mine has. ie. Hardi plank siding vs the dreaded LP products or T111. Plus I have extensive millwork in my home...more so than homes valued 4 times the price. What can I say? I just like the way it makes a home feel and I'm extremely handy. Also, your comps like Benjamin stated are laughable as well.

In zillow's defense, many of the things that you are speaking of, neighbors 4th bedroom (huge positive, especially if extra sq footage btw), extra molding, quality of materials etc., may actually show that your home is overbuilt for the area. More importantly there is no way to verify your addons electronically. A bank appraiser might elevate the quality of your home compared to others in the area, but only to degree that it is not overbuilt for the neighborhood.
I do agree with you that if they are using incorrect comps, comps from the wrong neighborhood, then that is something that they should correct. My guess is that you are being affected by recorded activity on your property, or the lack of it. If for example you are the original owner and never pulled permits, refinanced or anything, you will automatically get a different value than a neighbor whose property has.
But since your not interested in selling -- we are really only talking about something pretty meaningless arent we? Who cares what anyone says about the value of our homes, unless we have it on the market?

I have regularly checked my home on this site and have always been baffled by the results. After some time, zillow corrected my square footage (they were only listing half). My next door neighbor has the same floor plan and still have her listed at half the square footage. When I looked at the site today, my house had a 15k price drop for the past 30 days, and hers had a 1k price increase. We have similar size lots. But according to zillow, 900 sq. ft., 3 bd, 2.5 bth is worth slightly more than 1800 sq. ft., 3bd. 2.5 bth.
I dont get it.

In the past 30 Days I saw that the value of my house Zestimate dropped from I think 317 K to 304K. What would cause this? Thank you

Actually I figured it out possibly why my home is showing 50K lower than my neighbors. It's the satellite photo. It shows my grass extremely brown. I think your site needs to take a current photo of it. That may help.

I promise you that the aerial imagery of your home has absolutely nothing to do with its Zestimate.

Hey Drew, I was reall hoping for a reply to my post from earlier this morning.
I live in Graham and really so no rhyme or reason for the values that you have assigned my home.
My house is just shy of 1800 sq. ft., 3 bd, 2.5 bth, with .36 acre lot. Zillow showed a 15k decrease for the 30 day period. My next door neighbor has the same house, with a slightly bigger lot. But Zillow shows her house to be 900 sq. ft., 3 bd., 2.5 bth.
While my house declined considerably, her home inched up a bit.
Zillow now has her house as worth slightly more that mine, but again Zillow is showing half the size. Is there an answer to this?

I did have another question relating to the price per sq. ft.: Zillow lists mine as $304, how do you get a value of $275k for 1794 sq. ft. ?

In my opinion the valuations given by Zillow are a mixed bag. Some accurate, some not. If you have or are searching for a home in a cookie cutter housing tract where all the homes are roughly the same age and there are only a few basic models by the same developer using similar features and construction, Zillow is probably pretty accurate in their valuations. Where the site suffers is a general lack of confidence many people have due to numerous posts complaining that there are OBVIOUSLY some very bad Zestimates in the database. Zillow's response is usually "its just a starting point." (Oh well). That usually doesn't wash well with people who have their homes on the market and who think potential buyers may be influenced by what the seller considers a low Zestimate. Of course, Zillow's Zestimates are probably somewhat high in some cases also. However, I have never noticed anyone posting on this site a complaint that their Zestimate is too high. They will just be happy or think it's accurate and say nothing.
One positive thing about this site is you can get somewhat useful info without having contact with realtors unless or until you are ready.

"I have been looking at homes in 58052 area of Vegas. And alot of the homes the Zestmate is higher than what the house is listed for. If its more than what they are asking its not very helpfull for me. How can I get a better idea of a price for a house then?
Thanks Harry"
And here's another one from May 31
What do I need to do to get Zillow's attention? Brookfield, WI erroneously up 29.4% in 30 days.
