From what i've read online (not financial advice) the bank only requires one of the owners to use the property as their primary to qualify for a primary financing.From what I understand this will also very much depend on the internal guidelines of the particular lender you're talking to. 

What I mean is this Money market at Bank of America pays for instance 4%, the money market local Bank of Bricktown Pays 4.5%, an online outfit is offering 5%.

I would add, also check to see if you state has court cases on line.

Shop Around: Compare rates from other commercial banks, credit unions, or online lenders to find competitive offers.5.

I haven't been able to find the answer to this online.

@David S.Very limited info, but here are my thoughts...You're right about how much supply is coming online in Nashville.

The way it's portrayed online brings too many unethical people into the business, giving the good ones a bad reputation.

First, I need to learn how to protect myself and my current tenant against some of the issues I've seen online where renters will stay past the date they're supposed to leave.

Do not use a program for your computer when you can use an online rental manager for nothing.

Needless to say, I explored further by pulling up & printing all information and pics online pertaining to this property & even got in touch with the real estate agent who sold my friend this house to find out some info about the Granny unit I live in & if it was truly built without a permit.
