Three thoughts:
1st. How are you going to participate? Are you putting up the money and he's doing the work? Are you both putting up 50% and doing the work? This is very critical, as expectations will probably be broken if they are not nailed down. If you're both working, the guy who shows up at 5am (me) will eventually resent the guy who shows up at 9am and takes long breaks. It is very hard for people to get along when there is that much money on the line and a time crunch. If you're coming in with the money, and he's doing the work, I'd say you buy it, and pay him per job for the work, and a bonus based on how long it's on the market and what it sells for. You don't want him to get distracted, take a year to finish while you're paying taxes and such... If none of you are doing the work, one of you is still going to end up doing most of the contacting of contractors and things.
2nd. What is profit? If you're doing the work, you're just getting paid for your time. The one flip I did, I ended up doing a lot of the work. Yes, I took home around 20k, but I also had over 400 hours into it.... so maybe $45/hour before taxes..... not profit.
3rd. Yikes!! that deal does not give me any confidence. Have you factored in commissions and closing costs, as well as holding costs while you are flipping it? The flip I did was purchased for 100, sold for 200, and between the holding costs, repair costs, commissions (and I used hard money), I only took home 20... and I am very thankful for it. Also, let's say you're into it for 175 cash... you still have to put some money aside for maintenance and vacancies, so you would not have an actual income of 1200 if you rent, more like 1000. So, even if you don't owe anything on it (there's still taxes), you're return on investment would only be 6% cash on cash... which does not make this a good exit strategy. Make an offer in the 120 range, and then I'd feel a lot better about the numbers.
Let me know if all this makes sense.
