A new site, CyberHomes, shows 98122 homes have steadily risen in average value over the last three years.

It's a pretty useful site, with information on demographics, schools, weather, etc. and has inforamtion on every homes as Zillow does. One graph I liked was house sales by age of home.

Some of the math is dubious. A house purchased in 2003 purchased for $400K near me is estimated at nearly $1.1 million, and the house has has little to no improvement. The house will not sell for that, so clearly they have some work to do.
