With all of the technology at our fingertips today, it's very simple to log onto one of the multitude of big name websites to get a quick estimate of your home's value.  I talk to home sellers every day in What is my home's valuethe Tampa Bay area who have done this and then contact me to find out if the information is correct, or they trust it and are shocked to find out that it's not correct.  Let's talk about what these estimates are and are not.

Most of the major websites have an estimate but sometimes they're called different things to brand them to a specific website, such a Zestimate for Zillow.  The way that these estimates work is that a computer looks at all the homes that have sold in the area and attempts to find ones that are similar to your home in location, size, number of bedrooms and age of the home.  If you live in a large subdivision these estimates may be pretty close to market value.  If you live outside of a subdivision or very few homes have sold in your subdivision then, chances are, the estimate will be incorrect.  Also, if there are a lot of foreclosures in your area then the value is will be incorrect.

Zillow.com states on their website, "Zillow does not offer the Zestimate as the basis of any specific real-estate-related financial transaction.  Our data sources may be incomplete or incorrect; also, we have not physically inspected a specific home.  Remember, the Zestimate is a starting point and does not consider all the market intricacies that can determine the actual price a house will sell for."  

Each real estate market is different and because of this the percentage of error is different.  If you go to the Zillow website and scroll to the very bottom, click the link for Zestimates, then click the button for "How accurate is the Zestimate?", then you can find your specific real estate market and see what the margin for error is.  In Tampa Bay, the median margin for error on a Zestimate is 5.4%.  Only 70.3% of the homes on Zillow had an estimate within 10% of sold price of the home.  That means that almost 30% of the estimates on Zillow were more than 10% incorrect.  With a $250,000 home that is more than a $25,000 difference.

Here's what the other major websites said about their computer generated estimates:
