I am an associate broker who lives work and has our offices in Monroe County. You didn't mention a price range or specific location in the County so I ran a pretty open search. Only 2 came back on the MLS, and I just listed a house today that would consider it so that's 3. There are a few others I know would consider it as well just from working with other clients.
The previous answer was correct that on a land contract you're going to need cash--usually 10% down minimum. Lease options can be slightly less up front, and depending on your circumstances (how long it would take to get you financed) may be a better fit. If you'd like any info on these contact me anytime at email@example.com No hassles ever.
