I get a lot of info about appreciation rates from the TARR Report, a subscription-based site created by Stacey Anfindsen of Birch Appraisal Group in Cary. You can pull up the Top 20 subdivisions, the Top 30 subdivisions by area, average appreciation rate over the past 13 mos. for the subdivision you enter into the data fields, the average cost of new construction w/ similar sq ft, new construction lot values, average cost per sq ft in the area, and various quarterly market snapshots in the Triangle area (Cary, Raleigh, Durham, Orange). There are 3 counties covered in the TARR Report--Wake, Durham, and Chatham. The web address is www.tarreport.com. Depending on the company you work for, there may be access to even more data. Fonville Morisey has a section called High Value Data that lets us crunch numbers by zip code, area, subarea, etc. Centralized Showing System also has showing data reports available by price range and area. Also, there's tons of data available on TMLS' home page...you can get market reports there as well. You could also scope out articles in Triangle Business Journal or local websites. We get tons of info in our weekly sales meetings from the broker in charge, so if you're not getting enough info where you are, you may be able to get it with another company.
