House Hack Debt to Income Question

[Matt Cox]

Hi Everyone,

I've gotten mixed answers on this one, so figured I'd put it out there to the BP community. Here's the scenario:

-I am looking at doing a house hack on a duplex here in Portland, OR using an FHA loan at 3.5% down

-The monthly PITI + mortgage insurance is $3,200 a month

-I plan to live in the smaller unit, the bigger unit rents for $2,300 a month

For debt to income purposes, would I be "credited" with $3,200 a month in debt and $2,300 a month in income? OR would I simply be "credited" with $900 in debt? (for the sake of this convo, please assume the $2,300 has been deemed to be "consistent/reliable" by the underwriters.

Thanks!

-Matt
