Hi Steve. I have heard a few different methods, most of which involve logging on to a site that will tell you, but it's very general that way - ya know, the average appreciation for the Brookwood High School area from this year to that year was some percentage. When asked that, the best way I found is to go into GaMLS and pull sold properties for an area and basically do a CMA. It needs to be GaMLS because FMLS only goes back about 3 years.
Hope this helps.
