You really should be working with an experienced buyer broker. You may not know it but buying foreclosures is extremely risky, their hardly ever the deal a buyer thinks they are. I've attached a link below to an article I wrote specifically about foreclosures. I have helped many dozens of buyers purchase foreclosure properties over the years, however despite my buying, selling, flipping homes for over thirty years. I have never bought a foreclosure for myself and I'm in the business.
Get yourself some help before you find yourself in over your head.
