How do mortgage lenders count rental income?
The full answer
For seasoned rentals, underwriters work from Schedule E: rents received minus real expenses, with depreciation, and often the mortgage interest, taxes and insurance already counted in the payment, added back. A property that shows a taxable loss can still contribute positive qualifying cash flow once the paper deductions return.
For a purchase, there's no history yet, so the appraiser's market-rent opinion (or the executed lease) sets the number and the lender applies a vacancy haircut — 75% is the convention across major programs. If 75% of rent exceeds the property's full payment, the surplus adds to your income; if it falls short, the shortfall counts as your debt.
Two edges to know: some programs restrict using rental income from a departing primary residence without equity or reserve conditions, and short-term-rental income is inconsistently accepted — some lenders average host-platform statements, others want it on returns. When personal-income math still fails, DSCR loans qualify the property on its own rent-to-payment ratio instead.
