Why a conventional lender ignores it
Conventional underwriting wants income it can verify from the past, a signed long-term lease, two years of tax returns showing rental income. A property you haven’t bought yet, that you plan to rent by the night, produces neither. So the income gets valued at nothing and you get qualified on your personal debt-to-income alone.
That’s not a judgment about the property. It’s a documentation type that has no slot for what you’re describing.
