I am not sure, but I imagine that you could also help out and lend your credit to this type of purchase. 

Prosper and Lending Club also offer peer 2 peer loans, usually up to $40-$50k depending on which company you look at.

There are DSCR lending options in your personal name.

Aside all that, as others mentioned, you didn't lend enough info to give any specific answer to your specific situation.

Like @Chris Seveney said, private lending is a great way to go as well.  

Quote from @Rafael Pinho: It's brilliant when geniuses like FLW lend their talents to the noble cause of creating affordable quality.

By doing this we qualified for a larger mortgage because we could use the rent from the other tenant to qualify and there are better lending programs when it’s “owner occupied”.  

I have used owner finance and hard money mostly to build my portfolio but need some institutional refi in the future.I'm also thinking about how this affects taxes, insurance.Thanks in advance for sharing your opinions!

Lau, generally if you are financing with a commercial lender- we lend for business purpose only and a rental property would fall under that category.

When starting out it’s a pretty good deal for someone lend you all the money and you give them 50% of the profits.
