The qualifying-rent rules, in plain language
1–4 unit rental (long-term)
Purchase: the lower of the in-place lease or market rent - proposed leases don’t count. Refinance with a rent receipt: the lease amount, up to 115% of market rent. Without a receipt: the lower of lease or market. Vacant units aren’t permitted on a refinance.
Short-term rental (1–4 unit)
Purchase: market rent from the appraisal. Refinance: the lower of market rent or the 12-month average verified by a third-party management provider. Minimum DSCR 1.00; loans cap at $1.5M.
Condotel
Both sides get an 80% haircut: purchase uses 80% of market rent; refinance uses the lower of 80% of market or 80% of the verified 12-month history. Minimum DSCR 1.00.
5–8 units
Vacant units count at 90% of market rent (max 35% of units vacant on a refinance). Occupied: lower of lease or market with a receipt; without one, the lower of the lease or 90% of market.

Quick questions
Which DSCR program fits a 6-unit building?
A dedicated 5–8 unit DSCR program - qualified on the building’s rents with vacant units counted at 90% of market, and no more than 35% of units vacant on a refinance.
How is qualifying rent different from actual rent?
Programs discount rent for risk: leases above market get capped (115% with receipts on 1–4 unit refinances), condotels take an 80% haircut, and vacant 5–8 unit space counts at 90% of market. This calculator applies those rules automatically.
Can I use Airbnb income to qualify?
Yes - short-term rental programs use market rent on a purchase and the lower of market rent or your verified 12-month average on a refinance, with a 1.00 minimum DSCR.
What payment is used for an interest-only loan?
The interest-only payment (balance × rate ÷ 12) is the qualifying payment on 10-year IO structures; amortizing loans qualify on the 30-year payment.
Is this an approval?
No - it’s the same math the desk runs first. Lenders also weigh credit, reserves and property condition; a specialist confirms the real number before you apply.
