Its good to see someone trying to make a solid investment and keep his head above water. Your mind is in the right place, there's just a lot of fine details in between the lines that you can only learn from experience, trying and failing before success. Something like this you need to go into with a mental preparation that failing can be a reality and things don't always go as planned. Buying a home is a hit or miss. It's like buying a used car, you're buying someone's problems and you never know how much it was neglected. If you're willing to take a 50,000$ or more hit, then maybe it'll be worth at least trying.
If you're even going to consider fixing up a home for profit, you need to forget the word contractors and start learning to do things yourself. You'll be spending 50,000$+ just to fix up a home if you don't do it yourself. It's one thing to hire an extra hand or two, but you'll never see a cent of profit by hiring a bunch of contractors from a construction company to come in and fix everything. My family has many generations of property owners and the first thing you need to learn is that to save money, you do it yourself.
Im not saying you haven't thought of this but there are a lot of fee's that come along with owning property too. It's not just simply pay 50,000$ and you don't need to pay anything else. The majority of homes in that price range are going to need work before they are uninhabitable. So you'll be looking more along the lines of getting a bank loan to pay for the house, putting down $ on it, and using the rest of your cash to fix it up immediately because no bank would let you purchase the home without contract saying it will be getting fixed immediately.
