Down payment for a duplex/triplex/4 plex

[Annie Irizari]

I'm in business discussion to be a down payment private lender to a business colleague who is looking to start investing on a 4 plex. I can provide the down payment to an FHA loan. I'm thinking we need a business contract of some sort or owner financing ? What type of contract is applicable in this scenario . What should be in the contract/terms? Do I need an attorney to draw up the paperwork? What about an exit strategy? How does one typically structure something like this? Thoughts? Caveats? watch out for ? Thanks :-)
