House Hacking/ First time home buyer mortgage

[Matthew Ladner]

So i am looking at four units, two separate building that are each a duplex. I would like to get a first time home buyer loan, and my fiance and I are going to live in one unit and rent out the other three. Im wondering if a bank will allow us to do a first time home buyer loan with a lower down payment since there are two buildings?? Anybody else ran into this before??
