I would say continue as though you were going to purchase a property, and make the lease to own part of the offer. If this was a super hot market, it would be a little more difficult. However it's not that kind of market now. Sellers are trying to do creative things to sell their house, and if it releases them from their burden (i.e. covers their cost), they'll probably be pretty darn open to the idea. But make sure you consult/hire a real estate attorney (who has experience with lease to owns) who can fill you in on the intricacies and standards for the area for a lease to own.
