Everyone has had very good suggestions so far.
Remember that markets are ever evolving and what used to work in the past doesn't always work today or in the future.
You have to appreciate that if you have no money and no credit you are probably going to have to have seller finance which means you won't get the best deal on the price...for a rehabber this is the kiss of death. You make most of your $$ when you buy so you have to get the lowest price possible.
It does not take a lot of money to develop a solid buyer's list of 20+ buyers. Start here...then if you end up partnering you have something to bring to the partnership.
Let me know if this is helpful? Good luck, Brad
