John T Reed had an article up on his website where he outlines his strategy for fixer uppers. His basic premise was that if you're doing it for money, the house needs to be an absolute disaster to begin with. Fix it up to the level of being a 'fixer upper' so that you can sell it to your regular joe blow who tends to overpay for those types of homes with the intention of fixing it up for a profit.
