You really, really, really should call a real estate professional
There are many purchase options you should consider.
There are extremely important things you must know to submit a competive bid.
There is even more you must know to avoid making a gigantic economic mistake.
To think all this can be addressed in a actionable way on a internet Q&A session is faulty. Trolling aggregate websites and hudforeclosed.com will prove to be wasted time.
Demonstrate you are serious by calling a professional in the area where you intend to make your purchase.
Best of success to you,
