Physician loan to purchase duplex?

[Caroline Lucius]

Curious to know if anyone may have some insight for my situation... My fiance and I are looking to house hack a duplex in Chattanooga, TN in the next couple of months. He is a family medicine resident so we're seeking a physician loan as opposed to FHA in order to avoid the PMI that comes with a low down payment. Two lenders I've looked into so far only offer physician loans for a single-unit primary residence. Does anyone know if that is standard with physician loans or happen to have experience using this type of loan for an investment property? Thanks!
