Zillow has a number of great new features... most recently with the addition of "enhanced" heatmaps. The feature now has even more functionality allowing you to easily move around a city, compare cities within a state, or pan out to see the entire country. Not sure what you can afford to pay for heat? This should help. Other additions to the Zillow offering just in past week or so include support for the Safari web browser, a more open database where home owners can add personalized information to their listings (like updates and improvements), and myZillow... a personalized home page of sorts where you can keep tabs on teh value and value trends for multiple properties... keep tabs on the rise and fall of home prices for your entire family here.
