Best way to finance multiple duplex town homes

[Jonathan M.]

Looking a buying 4 duplex town homes for a total of 8 units. They are currently 80 percent occupied in the Tampa area with other 2 being rehabbed in a demanding neighborhood. under 1 million.

What is my best loan product, I am looking for the longest amortization and the lowest interest rate. 

Seems like it would be easier for to obtain a commercial loan because they look at the business its self rather than me.
