Need Help Please! Bank telling me anything over duplex is commerc

[Dakoda Spencer]

This is what I received just this morning from the bank:

"
This is directly from the regulation “Credit extended to acquire a rental property is deemed
to be for business purposes if it contains more than 2 housing units”.

"
I am trying to buy a 4 plex, with 20% down. Can I not get a 30 term with a fixed interest rate? The lending for rentals currently has me confused. I'd appreciate some valuable input.

This is what terms the commercial loans are, which I don't know is good or not:

10/3 ARM 6.625% - adjusting at Prime + 1.25% (Cap 2%)

7/3 ARM 6.375% - adjusting at Prime + 1.25% (Cap 2%)

5/3 ARM 5.99% - adjusting at Prime + 1.25% (Cap 2%)

3/3 ARM 5.625%- adjusting at Prime + 1.25% (Cap 2%)

1/1 ARM 5.25% - adjusting at Prime + .75% (Cap 1%)

***Floor: 4.25% ***
