| Lender pool | Broad | Narrower set of programs |
Why the long-term lease is the default
A twelve-month lease gives the underwriter one clean number to compare with PITIA. The appraiser’s rent schedule usually confirms it. Nearly every DSCR program accepts this approach, which keeps the lender pool wide and pricing competitive.
In California, a long-term lease also avoids the city-by-city maze of short-term rental rules. For most investment properties in large cities, especially where short-term rentals are limited to primary residences, the long-term lease is the only practical route for a non-owner-occupied loan.
When short-term income is worth presenting
In permitted vacation markets, such as parts of the desert, mountain communities and some coastal counties, a well-run short-term rental can produce revenue that supports a larger loan than a long-term lease would. Programs that accept short-term income typically want a solid booking history, often a year or more, or an appraiser’s short-term rent analysis. See our short-term rental cash-out page.
How seasonality and expenses change the math
Underwriters usually annualize short-term revenue and divide by twelve, then may apply an expense reduction for platform fees, cleaning and management. A property that earns heavily in peak months and little in the off-season can end up with a monthly figure that surprises its owner.
Here is a simple illustration with owner-style inputs. Say a cabin grossed $54,000 over twelve months, or $4,500 a month on average. If a program reduces that figure to account for operating costs and counts $3,600 a month, and PITIA on the target loan is $3,000, the ratio is 1.20. A long-term lease on the same cabin might be $2,700 a month, a ratio of 0.90 on the same loan. In that case short-term income is the stronger route, provided it is permitted and documented.
Risks to weigh
Before building a cash-out on short-term income, consider:
- Permit risk: rules can change, and some permits do not survive a transfer
- Insurance: guest-use coverage costs more, and wildfire exposure is common in vacation areas
- Reserves: some programs require more reserves for short-term rentals
- Your exit: if short-term income disappears, can a long-term lease still carry the loan?
Questions to ask before presenting short-term income
Is the permit in your name or tied to the property, and will it survive a refinance or a transfer to an LLC? Does your booking history cover a full year, including the slow season? Are platform statements consistent with deposits in your bank account? If short-term income disappeared next year, could a long-term lease still carry the payment? Honest answers to these questions tell you which income approach to lead with.
Making the choice
Run both income figures through the DSCR calculator using the same loan amount and costs. If the long-term lease alone keeps you near or above 1.00, the property has a safety net.
