I suggest checking to see if any of the local savings and loans in your area will do a "portfolio" loan. That means they won't be reselling it on the secondary market. With 50% down, they should be willing to be pretty lenient and won't charge as much as some "hard money" lenders.
Best of luck!
Hope this helps!
