.~ I will most likely purchase the first home (multi-family) using a bridge-DSCR loan combo or a FHA203K (3.5-20% down). 

The SST doesn't apply for legal 2-flats so if you want to use FHA it's probably better to target those that maybe also have a non-conforming basement or attic unit.This is why the 5% down conventional loan is a game changer for house hackers.

I'm guessing an investor who could afford an $800K house wouldn't have trouble getting a loan, but maybe they would like being able to make a small or 0 downpayment. 

With our structure, the development company owns about 45% of the equity when complete, and I own 50% of our company.So it will be about 22%

New loan is a 10/30.

My question is when applying for the lease, most properties in my market are run by a management company.

You guys need to get rid of that student loan debt.

With that being said, Columbus is one of the hottest markets in the US right now with some of the fastest population and job growth and companies moving and developing here.

However, the ex wife name remains on the loan itself.

LTV would be determined by the type of loan.
