Wow! Zillow is great! We used Realtor.com in conjunction with our local tax appraisor’s website when we were house hunting and I’m shocked with much information Zillow gets about a property. It actually puts a price tag on every house in the neighborhood, not the appraisal value, but an estimated market price.
They also have a cool page that shows some famous houses. Anyways, the site speaks for itself. Go there now and enter your address to see the value of every house in your neighborhood.
