What type of mortgage would work best for me?

[Michael W.]

I'm looking into deal in Philly for a $250k triplex. I'd be jointly purchasing with one other person (we're not related), and he'll live in one of the units (I will not). He has great credit and more than enough income to satisfy the DTI restrictions, but since I will contribute part of the down payment and be on the title, while not living in the unit, do you all have suggestions of what type of lender or mortgage would best help us out?

Thanks!
