The newspaper has just launched a Web service called Neighborhood Watch in which you can pick through more than 100,000 home sales from the past four or five years.

The Times' computer guru Matt Waite has done a great service by categorizing home sales, updated weekly from county appraisers offices, into 186 neighborhoods in Pinellas County and 35 neighborhoods in Pasco County. We're going to organize similar data dumps for Hillsborough and Hernando counties, too.

You can choose your neighborhood from a drop down box or insert a zip code. Up pops ALMOST EVERY RECORDED SALE in the community going back to 2004 and 2005. Click on individual addresses to get details of the transaction.

Did I tell you it's free?

Those of you who distrust statistics from the Realtor associations should be happy. Unlike Realtors, we include For Sale By Owner deals, new home sales not sold through the Multiple Listing Service and other deals that often slip through the statistical cracks.

We also do our own math in spotting sales and price trends. Needless to say, price declines vary wildly depending on which neighborhood you flag. Playing off the Web site, I'm writing a story this weekend to highlight some of price discrepancies in neighborhoods only a couple miles away from each other.
