You just have to love Zillow’s Zestimates.  Log in and look… poof… there is the Zestmate for your home.  Couldn’t be easier.  It’s almost too easy.  OK, it IS too easy.  And while I love the Zestimate just as much as everyone else, I also know that the chances of it being right are pretty slim.

"Lincoln Heights"I don’t want to slam Zestimates, though.  They actually ARE quite useful.  Their usefulness isn’t in their application to individual houses… it has more to do with looking at Zestimates for larger areas… ZIP codes, cities, regions.  The statistical variations that are the problem with looking at individual houses start cancelling each other out.  what we are left with is a pretty good measure of home values for an area.

Last year I posted up a breakdown of the Zestimate accuracy of individual listings in the Atlanta Metro Statistical Area.  The bottom line is that the Zestimate has about a 1 in 5 chance of giving you a value within 5% of the real market value of your house.  And the y are just as likely to be high as they are low.

If you are just curious, it is a fun tool.  If you REALLY need to know, you should talk with an Appraiser or a Real Estate Agent (depending on WHY you really need to know).  And remember, the real estate agent that tells you the highest value is probably wrong… and might even know they are wrong.  In the business, we call it “buying a listing”.  The strategy there is to promise a high listing price, and then come back after you are in a listing agreement and try to get the price down to where it should have been in the first place.  The biggest problem with that strategy is that it completely wastes the prime market time… when the house is first listed.  The end result is that the price usually ends up lower than if you had opted for a slightly lower price to begin with.
