Conventional Mortgage rate SFH vs. multi family

[Jason Homa]

I'm looking for a conventional bank loan for a 2 Family home. The lender I'm working with says the rate is about 1% higher for the MF than a single family home.

It's throwing all my numbers out the window!

Have you had the same experience? I thought as long as it is 4 units or less, same rate would apply as a SFH

Thanks
