Do you want to know how much your house is worth? If you follow PFBlog, you probably already know Ditech's Free eApparaisal Service. I just became aware of another powerful free home price check service provided by Basis100. It provides more informative report than Ditech or any other services I ran into.

When I tried my house in the system, I got a valuation estimate of $330,000 to $363,000. The report also listed out three recent transactions that occured within 0.03 to 0.38 miles of my address. You bet I am happy to see the results: even for the low-end estimate, my house is worth $10,000 more than I keep in my accounting book.

How does Basis100 estimate your home value? According to the online documentation of Home Price Checker Version 2:

The HPA (Home Price Analyzer) is a tool designed for home price trend analysis. It is driven by a Database containing nearly 40,000 separate indexes that cover approximately 80% of the homes in the United States. The indexes themselves are computed using the repeat sales methodology from a database of over 40 million separate observations.

HPA functionality includes computation of a current VALUE and confidence SCORES for a home using the single property screen. Selection and display of a specific zip code index or county chart using the Chart Selection Screen. Selection and display of home price trends using the Area Ranking Selection Screen and the Area Ranking Display Screen.

Pretty fancy stuff, isn't it?
