Best way to compensate someone that loans the down payment

[Joe S.]

So has someone used money partners for the down payment only. I’m not sure what to offer someone that is interested in investing with me as far as them putting the down payment on a purchase. They would not be signing a loan or anything of that nature. Should I offer a higher interest-rate on the money they put down? This would keep things simple. I’m not a huge fan of co-ownership, Unless it’s a spouse.

If anyone has experience with this sort of arrangement or recommendations please chime in.
