I may be able to steer you in the right direction. Most counties in florida have an online property apprasial office. Keep in mind the apprasial may be very different than the real home value. Anyways, if you search the county apprasial office online they usually have maps of the entire county you can search by address and I know mine even has ariel photos of the property. Some are so advanced you can see what the actually recent home sells in there are and the amount in which they sold.
