More often than not, a 2-4 unit flip type deal will find it hard to get financing depending on its condition and you will most likely get offered out by other investors putting in all cash. 

My buddy just approached me with an offer to invest with him in buying foreclosures, he is a GC and he has done house flipping before, he wants me to invest 30K-50K of my own money and use it to get a 6 month rehab loan from a hard money lender at a little over 11% interest, after the House was finished we would split 50/50, he would also add me to his LLC that we would use for that future buy, the reason I’m thinking about investing Is bc I own my own business which will bring 200K this year in gross profits, the down side of my business is that I work 12 hour a day 5 days a week, and I feel that I’m slowly burning out.

Hard money lenders don't generally like to loan to owner occupants.
