The Quick Read: Once a short-term rental is leased monthly or longer, underwriting stops measuring booking history and sizes the income on a signed lease or the appraiser’s market rent, so your file needs a clean conversion date, the executed lease, proof the first rent arrived, and an appraisal rent schedule that agrees with the lease.
- The income number becomes the lease or the appraiser’s monthly market rent. Old nightly revenue generally stops counting.
- DSCR is monthly rent divided by PITIA. Only the rent side changes after conversion.
- Keep the short-term period and the long-term period separate in the file. Never blend them into one income figure.
- The lease, the appraisal, the insurance policy, and the listing status must all tell the same story.
- Clearing 1.00 is not the same as positive cash flow.
Key Terms Defined
DSCR (debt service coverage ratio) is the property’s monthly rent divided by its monthly housing obligation. A ratio of 1.00 means rent equals the obligation.
PITIA stands for principal, interest, taxes, insurance, and association dues. It is the full monthly obligation on the loan.
Conversion date is the date the property stops being a nightly rental and starts being a monthly lease. Your paper trail pivots on it.
Market rent schedule is the appraiser’s opinion of what the property would rent for per month on a long-term lease. It is a separate exhibit from the value conclusion.
Seasoning is the waiting period a lender wants between buying a property and refinancing it, especially for cash-out.
LTV (loan-to-value) is the loan balance divided by the property’s appraised value or price.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.

As of Oct 15, 2026 · General Freddie Mac market benchmark, not a Lendmire loan offer. Nightly rate, occupancy, taxes, and insurance are editable estimates. Qualifying income for short-term rentals varies by program — some use appraisal market rent, others use documented STR history or projections — and is confirmed in underwriting. Not a Loan Estimate, approval, or commitment to lend. Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
What Changes the Moment a Lease Starts
Everything about the income basis changes the day a tenant signs. Before conversion, a lender looks at nightly revenue, bookings, and platform data. After conversion, the file is a long-term rental, and the lender wants a lease and a market rent opinion.
Think of it as swapping the top half of the fraction. The formula is the same. Only the numerator moves.
| Factor | Before conversion (STR) | After conversion (lease) |
|---|---|---|
| Income source | Nightly bookings | Signed monthly lease |
| Main evidence | Booking and payout records | Lease, deposit, bank deposits |
| Appraiser role | Value plus market data | Value plus monthly rent opinion |
| Typical reviewer question | Is the income stable? | Does rent cover PITIA? |
A new STR owner often feels the sting here. You may have a handful of strong bookings and a plan that looked great on paper. Those bookings help your story as a host. They rarely help the math once the unit is leased.
Why does this matter? STR programs across the network typically expect about 12 months of host experience. A first-year owner often does not have it. Converting to a lease can move the file onto a simpler track, one that rests on a document the lender can read in a single sitting.
How Underwriting Treats the Converted Property
The lender qualifies the file primarily on property-level rental income covering the payment, subject to lender guidelines. For a converted property, that income is the lease or the appraiser’s monthly market rent. Which one governs depends on the program, and the comparison between them is where files get interesting.
The appraisal does two jobs. It sets value, which drives LTV. It also supplies a market rent opinion on a rent form. For a one-unit property or condo, that form is the 1007. For two to four units, it is the 1025, which shows rent unit by unit. Fannie Mae’s appraiser newsletter describes the 1007 as the schedule that documents estimated monthly market rent on single-family investment properties, and it can also be used for condo investment properties. DSCR loans are not agency products. The form names and what the forms measure are the only things worth borrowing here.
The rent schedule is not a nightly-rate tool. Fannie Mae’s guidance, as discussed on The Appraisal Update podcast, says the 1007 cannot estimate the nightly fee for a short-term rental. So do not expect the appraiser to turn your Airbnb history into a number.
The appraiser also does not decide what income counts. McKissock’s appraiser education piece explains that the appraiser values the real property only. Furniture, fixtures, equipment, and business income stay out. The 1007 documents monthly rent, and the lender makes the final call on income. Appraisers may not multiply a nightly rate by 30, with or without deducting business expenses. That shortcut ignores vacancy, furnishings, and operating costs.
Which rent does the lender use? Practice varies by program across the network. A common approach is the lower of the in-place lease and the appraiser’s market rent. Some programs lean toward the lease. Others lean toward the schedule. Ask which one your lender uses before you price a lease.

The Document Checklist
Most files stall because a document is missing or two documents disagree. Assemble the file in four groups.
| Group | Document | What it proves |
|---|---|---|
| Rent evidence | Executed lease and amendments | The monthly rent and term |
| Rent evidence | Deposit and first-month receipts | The tenant actually paid |
| Rent evidence | Bank statements | Deposits match the lease |
| Property and legal | Appraisal with rent schedule | Value and market rent |
| Property and legal | HOA or condo documents | Rental use is allowed |
| Borrower and entity | ID and entity papers | Who owns the property |
| Insurance and reserves | Landlord policy declarations | Coverage matches the use |
| Insurance and reserves | Asset statements | Reserves are on hand |
Two details trip up new owners.
First, the insurance swap. A policy written for nightly guests describes a different risk than a policy written for a tenant. If the declarations page still says short-term rental while the lease says twelve months, the file contradicts itself. Switch the policy and keep the new declarations page.
Second, the entity papers. If the property sits in an LLC, the lender will want the formation and authority documents, subject to lender program eligibility. Make sure the lease names the same owner as the title.
Treat the table as the common core, then confirm specifics for your program.
The Paper Trail From Last Booking to Funding
Sequence matters as much as content. A lender reads your file in order, so the order should make sense.
1. Pick a conversion date and support it. Line up the last nightly booking, the lease start, and the first rent deposit. A gap with no explanation raises questions.
2. Deactivate the listing. A live nightly listing next to a long-term lease is the classic contradiction. Pull it down, and keep a screenshot or confirmation.
3. Sign the lease and collect the deposit. Keep the executed lease and the receipt for the deposit and first rent.
4. Swap the insurance. Move to a landlord policy and keep the declarations page.
5. Separate the two periods. In the file, label the STR period and the long-term period. Do not average them.
6. Order the appraisal. The appraiser reports value plus a monthly market rent on the right form.
7. Compare lease and market rent. If they disagree, expect the lender to pick one by program rules. Find out which before you submit.
8. Check the hidden gates. Legal rental use, HOA minimum rental terms, reserves, credit, and seasoning on a cash-out.
9. Submit one consistent file. Read it once as a stranger would.
Here is the catch. Many investors order the appraisal first and sign the lease later. Then the market rent comes back, the lease gets written to match, and nobody has checked whether the number clears. Run break-even rent against PITIA before you order the appraisal. It costs nothing.
Worked Example: One Property, Two Income Bases
Run the numbers on a modeled single-family rental. These are assumptions for illustration, not market data.
Say the property earned strong nightly revenue during a good season. On the STR basis, coverage looks like roughly 1.35x. The owner then converts to a twelve-month lease. Long-term rent is lower, as it usually is, because the furnished premium disappears. On the lease basis, coverage drops to roughly 1.05x.
Same house. Same loan. Different numerator.
That 1.05x is still above 1.00, but only barely. Remember that 1.00 is where select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger ratios generally open better pricing and leverage tiers.
If the market rent came back lower than the lease, say the file lands near 0.95x. The levers are straightforward:
- Bring more down payment. A larger down payment lowers the monthly obligation and can lift the ratio.
- Lower the leverage. Less loan against the same rent improves coverage.
- Look at a different structure. Interest-only periods and extended terms are available through select lenders in the network.
- Consider a sub-1.00 path. This is available through select lenders, with leverage and terms adjusted. It is reviewed under lender guidelines, credit approval, and property review.
- Pick a different property. Sometimes the honest answer.
A bigger down payment helps, but it never erases credit floors, reserve rules, leverage caps, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
On leverage, STR purchase programs top out at 75% LTV on the strongest files. On short-term-rental collateral, refinance and cash-out top out around 70%, with a 640 credit score as the typical floor. A leased property is reviewed as a long-term rental file, so the leverage tier a lender assigns after conversion depends on the program the file lands in. Confirm it before you commit to a purchase price or a cash-out amount. The parameters here are typical ranges from select wholesale-network guidelines, not commitments to lend. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Across the network, one pattern shows up on converted files. Cash-out requests often hit the coverage wall before they hit the equity wall. Pulling cash out raises the new payment, and lease rent is usually lower than old nightly income. The equity may be there, but the ratio caps the loan.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
Where Files Break
Most problems on a conversion file come from contradictions, not weak numbers.
- Live listings. The listing is still active, or a platform page still shows availability.
- Gaps in the timeline. The last booking and the lease start are far apart, with nothing in between.
- Mismatched insurance. The declarations page describes nightly use.
- Lease and rent schedule disagree. One says one thing, the other says something quite different.
- Blended income. The file averages STR months and lease months into one figure.
- Missing HOA review. The condo documents set a minimum rental term the lease does not meet.
- Unsupported deposits. The lease says one amount, the bank statement shows another.
(Yes, lenders really do read the bank statements against the lease.)
Edge Cases Worth Knowing
A lease below the old STR income. Class Valuation points out that a rent schedule built on leases can understate what a furnished nightly property actually earned. That mismatch can produce a lower ratio than the property’s STR history suggests. It works the other way too. In a weak STR market, a long-term rent fallback can rescue a file that would not pencil on nightly income.
Mid-term rentals. Furnished stays of 30 days or more are often read as long-term by many programs, so the furnished premium may not be credited. A corporate contract or an agency contract needs signed paperwork and bank proof. Platform history alone does not carry it.
Two- to four-unit properties. These use the 1025, which has unit-by-unit rent. If only some units were short-term, document each unit separately.
Condos. Association dues sit in the PITIA denominator, so a high-assessment condo drags coverage harder than a comparable house. A condo may also need project eligibility and HOA document review. Check minimum rental terms early. Investors sometimes discover long minimum-stay rules only after the lease is signed.
Prepayment penalties. If the new loan carries one, converting back to STR and refinancing again can cost money. Know the terms before you sign.
Ineligible property types. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs, however they are rented.
Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Should You Convert, Keep the STR, or Run Both?
This is a genuine judgment call, and the answer depends on your history and your numbers.
Convert now when you have little booking history, your STR plan is underperforming, or you want a file that rests on a signed document. The loan is simpler to document. You trade upside for certainty.
Keep the STR basis when you have about 12 months of host experience, strong records, and a market where nightly revenue clearly beats a lease. Then an STR program may fit better, at its own leverage caps.
Run both when you are unsure. Model coverage on the lease and on STR income. If the lease number clears comfortably, convert with confidence. If only STR income clears, the property is leaning on income that is harder to document, and the file will be reviewed that way.
One more reality check. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the calculation. Clearing 1.00 does not mean the property puts cash in your pocket each month. Tax treatment varies; consult a qualified professional.
Frequently Asked Questions
Does my old Airbnb income count after I sign a lease?
Generally not. Once the unit is leased long-term, the income basis is the lease or the appraiser’s market rent. Your booking history helps show you operated the property, but it rarely changes the ratio.
Do I need a lease before I apply?
It depends on the program, but a signed lease is the cleanest evidence of long-term income. Without one, the lender typically leans on the appraiser’s market rent. Having both lets the lender compare them.
What if my lease is higher than the appraised market rent?
Expect the lender to be cautious. A common approach is to use the lower of the lease and the market rent. If the lease sits well above market, the ratio may be calculated on the lower number.
Can I just multiply my nightly rate by 30?
No. Appraisers may not do this, and it ignores vacancy, furnishings, and operating costs. The monthly rent figure comes from long-term comparable rentals, not from nightly pricing.
Does clearing 1.00 mean the property cash flows?
No. The ratio only compares rent to PITIA. Management, repairs, utilities, vacancy, and capital costs are not in it, so run a separate cash-flow estimate.
