Hi Aoibheann (wow, what language is that?? It's amazing!), I agree with Lisa and Goran that there is not really a good website for this type of thing. I would be VERY cautious on Craig's List, as there is a lot of listing theft (scammers posing as real estate agents). We have been victims of it once, and I stopped a friend from rent-to-owning on a property where the owner was in default on his mortgage. In my opinion, any house that is for sale has the potential to be a lease-to-buy home-- it depends on the Seller and their circumstances. Let me know if you have any questions or if there's anything I can do to help.
