Ideally, you'll find a wholesaler you can really work with who will involve you before they get the house under contract so that the contracted price works for everyone, including the seller.

Owning it directly and actively can give you very high returns with the Leverage involved but requires quite a lot of work, quite a lot of your time, and quite a lot of your personal liability.
