Hi,
On my first flip deals I had private high net-worth investor put up all the cash. The private cash secured by a note on the property and vested ownership. I then did all the work and we split the profits 50/50. Though there are ways to make the deal more profitable there are inherent benefits with this strategy as follows:
1. Don't have worry about making payments therefore delays in project aren't as costly.
2. No costs involved that would normally be associated to an expensive hard money loan.
3. If you do well for this investor they will most likely expose you to their network.
4. You can close quicker and use a cash offer as negotiating tactic to get a better price.
5. You can buy at foreclosure auction with cash as well( Though this is much more risky proposition and you need to do your homework.
Ultimately this option gives you the most flexibility and doesn't put burden of an expensive hard money loan over your head. I think this best option when starting out. Right now is time to create those relationships to be ready for opportunities down the pipe.
