Gary, first off I would select a few areas, and determine what price range you would like to invest. You need to start by narrowing that down. I try to flip homes within a 15-20 minute drive. I also only target a few areas and in the $60-130 price range. It takes time to learn how to recognize a deal so getting to know the area and having your realtor run comps is very important. Eventually you will recognize a potential good deal on your own simply by spending time looking online and physically visiting homes in the areas you would like to invest.
Another thought is determining just how much rehab you are willing to do. Are you willing to deal with mold, foundation, roofs, and other more serious issues or are you just wanting to update a home? That in itself will possibly eliminate some.
Good luck! Having a good real estate agent is invaluable. Also, get a subscription to www.foreclosure.com. I see deals sometimes before my agent does.
