HomeLiberty has a program that is exactly what Macgreggor is asking for. We cash buy the REO property and then sell it back with seller financing. There is no need for goofy HELOC or 3rd party financing.
It's not a lease-buy-back. It is straight sale with a 30 year fixed note.
If the deal is that good, you might be able to find a hard money lender to finance the purchase, but the challenge will be getting a refi loan to repay the purchase loan (seasoning & credit issues). If the property was yours, most investors will probably will leave it alone - "lease options" aren't something that most investors do out here. But good luck either way.
