There was a web site I once used. That you could look up the comps, what the buyer bought it for and the new buyers name. Would anyone know this site or one like it? :crossfingers
Sounds like something your county courthouse on-line records repository might provide. What state and county are you interested in?
Any RE transaction is public record. Try your local govt. website. You can always go your City Hall and look up the records yourself the old fashioned way. :biggrin
