date of purchase property search?

[Warren Smith]

I'm trying to find a means to search properties -  land and multifamily - that would render results based on date of purchase. Reasoning is thus: find mom and pop owned properties that may be c class or similar, owned free and clear, potential for seller financed.  If anyone has done this kind of search in the past, or even has a place to search and some guidelines they have used in the past, this seems like a great tool to share with the community.  In advance, thanks for your input!
