@Kamal Martin maybe "house hacking" wasn't the right term.... but correct me if i'm wrong, are you referring to renting the property room-by-room?
There are a TON of people who do this and utilize DSCR loans, specifically i see it in college towns, as the property cash-flows beautifully this way.
Unfortunately, DSCR lenders are more concerned with market rent, and even if you were to provide 6 leases for one property, one for each room, adding up to $10k/mo in rental income, they wont underwrite it that way.
I usually recommend my clients give me one lease for the entire property in this scenario, it can have everyone's name on it, and the actual rent amounts... but the lender will go off the LESSER of the two - lease agreement vs market rent from the appraiser.
That said, you'll get chopped down by the market-rent component.
There are lenders out there, though, that do not look at DSCR, go negative DSCR, or go no-ratio. If the property is only cash-flow positive w/ room-by-room rents, these may be the better option for your scenario.
