USDA Loan Confusion 16 Unit Rural Senior living home Need Help

[Alex Schar]

I'm trying to purchase a 16 unit senior home that is currently enrolled into the USDA Rural development program. All of the lenders I have spoken to say they can only lend on a 1-4 unit property. Who do I need to talk to get a loan on this property? Is there anything else I should know? I've heard you have to live in it for a year but I'm pretty sure that's just FHA? Anyone done this before?
