DTI: Rent by room income on schdule E

[Michael Shea]

I'm contemplating renting out an investment property(non-primary residence) on a room-by-room basis with separate longer-term leases for each bedroom. I'm curious if the income from these rentals, listed on Schedule E, will be factored into my Debt-to-Income (DTI) ratio. My understanding is that when renting out rooms in a primary residence, the income is classified as boarder income and isn't counted towards DTI, as outlined in Fannie Mae's guidelines(https://selling-guide.fanniemae.com/Underwriting-Borrowers/I...). However, since this property isn't my primary residence, I'm unsure if the same rule applies.
