DSCR vs. Conventional Loan for a Short-Term Rental

The comparison at a glance

The core difference is whose income the lender underwrites: yours, or the property's.

How each loan counts short-term rental income

This is the biggest practical difference for a vacation rental, and the conventional side changed recently.

Conventional. Fannie Mae's Selling Guide defines a short-term rental as "a furnished, residential property rented for brief periods," typically "less than 30 consecutive days." Its short-term rental income policy applies to "One-unit investment properties only."

• On a purchase, the lender uses a Form 1007 based on long-term rents, or validated rental data for short-term comparables from an MLS or property management companies. It multiplies the monthly gross rent by 50% and subtracts the full payment (principal, interest, taxes, insurance and association dues). Fannie Mae says "The remaining 50% accounts for vacancy losses and maintenance expenses." A positive result can only offset the property's own payment.
• On a refinance, the lender uses your most recent Form 1040 with Schedules 1 and E, averaging the cash flow over 12 months.

DSCR. DSCR lenders set their own rules. One lender's 2026 guide says short-term rentals are eligible "with select lenders," with some accepting 12 to 24 months of booking data or a market-rate appraisal. Many discount projected income for a new purchase.

That gap is why many investors buying a new short-term rental find a DSCR loan easier to qualify for, even when it costs more.

Who each loan suits

Pick the loan that matches your documents and your portfolio, not the one with the lowest headline rate.

A conventional loan usually fits if:

• You have W-2 or well-documented self-employment income that covers your debts with the new payment included.
• You own few financed properties, well under Fannie Mae's limit of 10.
• You plan to hold for a long time and want the lower rate and no prepayment penalty.
• The property already has a tax return history that shows its rental income.

A DSCR loan usually fits if:

• Your tax returns show low income after deductions and depreciation, even though the business is healthy.
• You own many properties, or are close to the conventional limit.
• You want to close in a company name.
• You are buying a new short-term rental with no history and need the lender to count its projected income.

Reserves and property limits

Conventional loans tie your reserves to how many properties you finance, while DSCR lenders mostly look at the loan in front of them.

Fannie Mae's Desktop Underwriter requires six months of reserves for an investment property transaction. On top of that, it adds reserves on your other financed second homes and investment properties as a share of their combined unpaid balance:

Fannie Mae allows up to 10 financed properties for a second home or investment property loan underwritten through Desktop Underwriter. Each financed property counts once, however many mortgages it has, and your financed home counts too.

DSCR reserve rules vary. One lender lists 3 to 6 months of payments for loans up to $1 million, 6 to 12 months from $1 million to $2.5 million, and 12 months or more above that.

Cost: rate, fees and penalties

Conventional loans usually cost less; DSCR loans charge for the flexibility.

A conventional mortgage that meets the qualified mortgage rules has limits on points and fees, and the lender must verify income or assets and debts, according to the Consumer Financial Protection Bureau. DSCR loans do not verify personal income that way, so they are usually sold outside those rules and priced higher.

DSCR pricing moves with three levers. One lender's 2026 guide puts the preferred ratio at 1.25 or higher, lists credit tiers from 740 and above down to below 660, and says moving from 20% down to 25% down improves the rate by about 0.15 to 0.25 percentage points.

Before you compare offers, ask each lender for:

1. The rate and APR at your actual down payment and credit score.
2. All points, origination and underwriting fees.
3. Any prepayment penalty, and how it steps down by year.
4. Required reserves, in dollars.
5. How it will count the short-term rental income, in writing.

Run both loans through the same deal

The right loan is the one that leaves the deal working when bookings are slow, so test both before you decide.

1. Put the purchase price, a realistic income estimate and real costs into the deal analyzer.
2. Check the ratio a DSCR lender would see with the DSCR calculator.
3. Run the conventional and DSCR payments through the cash-on-cash return calculator at your expected occupancy, 10 points lower and 20 points lower.
4. Add the closing costs and reserves each loan needs to your cash invested.

A common path: start with one, refinance into the other

Many investors use both loans over the life of one property.

• DSCR first, conventional later. Buy with a DSCR loan, build a year or two of rental history on your tax return, then refinance into a conventional loan if the numbers support it. Check the prepayment penalty first.
• Conventional first, DSCR later. Use conventional loans for the first few properties, then move to DSCR loans as you approach the financed property limit or as reserves on the existing loans grow.

Either way, a refinance has its own closing costs, so count them before you plan on it. A CPA can tell you how the loan type and ownership structure affect your taxes, and an attorney can review borrowing through a company.

The bottom line

A conventional loan qualifies you; a DSCR loan qualifies the property. If you have strong documented income and few financed properties, a conventional loan usually costs less, and Fannie Mae now counts short-term rental income on one-unit investment properties, at 50% of market rent on a purchase. If your returns understate your income, you own many properties or you want to borrow through a company, a DSCR loan is often the practical route at a higher price. Test both against a slow year before you sign.
