Because laws and customs vary considerably by state, the first thing I would do is find a good RE attorney who is well versed in private lending IN YOUR STATE.Knowledge of SAFE act considerations, Usury laws, etc can save you a boat load of money and headaches later.I would probably also suggest either placing your funds with a lender who has a pool (you'll get a lower return) or working with a broker very experienced in private loans.

You could grab something in the midwest, but that's a rough tenant pool and properties don't appreciate at the same rate as they do in the west.
