There are programs for no credit history but a "shallow" history and low score make it more difficult to obtain financing, especially if the score is below 620.
You can always qualify for "hard money" if you have 50% down payment but that's expensive.
Why not focus on improving your score? I can help with some suggestions if you wish.
Typically banks that own foreclosed homes do not offer any special financing on them, a few larger lenders like wells fargo or countrywide may offer you loans through their companies but there is no special rate or discounted terms. You should get a buyer broker who can assist you with financing and get you into the house. they will assist you in mkaing an offer. good luck... more
