The Quick Read: A DSCR lender counts one documented, full-year average of rent, never your best month. Which figure goes on top of the ratio depends on how the cabin is run: a signed lease, twelve months of nightly booking history, or the appraiser’s market-rent opinion. Whatever the source, slow months count as much as peak ones.
- Three income sources exist: a lease, booking history, or an appraiser or market projection. The method you pick decides the number.
- Seasonal income is averaged over twelve months. A summer rush does not carry the year.
- The ratio compares counted rent to the full monthly payment (PITIA, defined below). Clearing it is not the same as cash flow.
- Short-term rental files typically run at lower leverage than long-term rentals, and show up with a 640+ credit score and about 12 months of hosting history on most files.
- Local rules, HOA rules, and road access can decide whether nightly income counts at all.
Key Terms Defined
DSCR (debt service coverage ratio): the property’s counted monthly rent divided by its monthly housing payment.
PITIA: principal, interest, taxes, insurance, and any HOA dues, which together make up the payment in the ratio.
Counted (qualifying) rent: the single monthly income figure the lender plugs into the ratio after verifying and trimming it.
Trailing twelve months: the most recent full year of actual income, totaled and divided by twelve.
Form 1007: the appraiser’s single-family rent schedule, which documents estimated monthly market rent. Multi-unit properties of two to four units use Form 1025.
Haircut (expense factor): the slice of gross short-term income a lender trims before running the ratio, a stand-in for operating costs and vacancy.

What Number Goes on Top of the Ratio for a Seasonal Cabin?
One monthly number goes on top: the documented income for a full year, divided by twelve, then trimmed where the program calls for it. The cabin’s brochure rate does not go there. Neither does the holiday weekend that booked solid.
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. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Your personal paycheck is not the test; the cabin’s income is.
On the bottom of the ratio sits PITIA. That means taxes, insurance, and any resort or HOA dues count against the cabin too. A cabin in a managed community can carry real dues, and they go in the denominator.
Across the wholesale network, 1.00 is where select programs start: rent that just covers the payment. Stronger coverage opens better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Exact eligibility depends on lender guidelines, credit, reserves, and the property itself. The complete DSCR loans guide covers the ratio in full.
The Three Income Sources, Side by Side
Most files use one of three sources, and the right one depends on how the cabin operates today.
| Source | When it applies | Strength | Cabin weakness |
|---|---|---|---|
| Signed lease | Long-term tenant in place | Simple, documented | Capped by market rent |
| Booking history | 12 months of nightly hosting | Real, verifiable income | Slow months drag the average |
| Appraiser or market projection | New or converted cabin | Works without history | Often lower than hoped |
The first source is a lease. When the lease and the appraiser’s market rent disagree, underwriters generally credit the lower of the two. A lease above market does not count in full. A vacant cabin leans on the appraiser’s market rent alone.
The second source is hosting history. Platform earnings exports, bank deposits, and manager statements show what the cabin actually earned. A booking calendar export helps show occupied versus available nights.
The third source is a projection. An appraiser may add a narrative short-term income analysis, or a vendor may supply a market projection. Class Valuation, an appraisal firm, notes that competent short-term rental appraisers use a labeled projected-income analysis as an addendum rather than the standard rent form.
Why the Appraiser’s Rent Schedule Misses Nightly Income
Form 1007 was built for monthly leases. McKissock, an appraisal education provider, explains that appraisers use it to collect one-unit rental comparables and document estimated monthly rent, and that the lender makes the final income decision. A Fannie Mae appraiser update describes the form the same way. It is cited here only to define the form. DSCR loans are not agency products.
HousingWire reports that seasonal demand, nightly pricing, cleaning costs, and management fees cannot be captured on the form. It adds that forcing nightly income onto it often produces artificially low coverage. That is why the income method matters as much as the cabin.
Two misconceptions fall out of this. First, “multiply the nightly rate by 30” is not a valid way to build market rent. Second, an appraisal rent opinion will not show your Airbnb earnings. It shows what a tenant would pay monthly.
From Peak Revenue to Counted Rent: The Step-by-Step Walk
Here is how a lumpy year becomes one number. The order matters.
1. Choose the income method first. Lease, booking history, or projection. Choosing before the appraisal is ordered prevents a surprise fallback to the 1007 figure.
2. Document gross income. Platform exports, deposits, and manager statements. Reconcile payouts to bank deposits so the totals match.
3. Total twelve months. Add every month, including the dead ones. Months the cabin was closed to guests count as zero.
4. Divide by twelve. The result is a monthly average. Peak months do not get extra weight.
5. Apply the trim. Many programs reduce gross nightly income to stand in for operating costs. Market surveys report factors in a range of roughly 20 to 25 percent. Treat it as a market survey number, not a network figure. Within our network, the trim varies by program and lender.
6. Divide by PITIA. The result is the coverage ratio.
Manager statements deserve a second look. Statements that already net out management fees can hide gross revenue, and the lender needs to see what the cabin brought in before the trim.
A Modeled Cabin, Peak Versus Average
This example is illustrative only. It uses invented relative figures, not market data.
Picture a cabin with a strong summer, a decent fall, and a quiet winter. Say the three busiest months each earn four units of income, the three shoulder months each earn two, and the six slow months each earn half a unit.
| Period | Months | Units per month | Total units |
|---|---|---|---|
| Peak season | 3 | 4 | 12 |
| Shoulder | 3 | 2 | 6 |
| Slow season | 6 | 0.5 | 3 |
| Full year | 12 | n/a | 21 |
Averaged over twelve months, that is 1.75 units a month. The peak month shows four. An owner who plans around four sees a payment that looks easy. A lender who counts 1.75 sees something much tighter, and after any trim, tighter still.
Suppose the payment equals exactly 1.75 units. The peak snapshot says coverage is above 2.0x. The full-year average says roughly 1.0x before any trim, and below 1.0x after one. Same cabin. Same year. Different answer, because one method counts the slow months and the other pretends they are not there.
This is the core cabin problem. A cabin with a steady spring-to-fall season and a modest winter averages well. A cabin that earns most of its revenue in about eight weeks and sits nearly empty otherwise may not cover the payment on a twelve-month average.
What Counts and What Doesn’t
Not every dollar a guest pays is rent. The lender wants to see income tied to the stay itself.
| Income line | Usually counted? |
|---|---|
| Base nightly revenue | Yes |
| Cleaning fees | Varies by program |
| Lodging and occupancy taxes | No, they pass through |
| Add-ons (firewood, hot tub, pet fees) | Often excluded or reviewed |
| Owner-use or blocked nights | No income, but nights count as available |
The safest approach is to separate base revenue from ancillary charges in your records. Lenders tend to credit the clean line and question the blended one. Program treatment differs, so ask before assuming.
When History Is Partial or the Cabin Is New
A cabin with only six to nine months of bookings, or one that started renting mid-year, usually falls back to another source. The file may use an appraiser’s short-term analysis, a market projection, or the long-term market rent from the 1007. A short-term rental purchase generally expects about 12 months of hosting history on most programs, so a thin record narrows the options.
A practical decision list:
- Full twelve months of platform history: use it. It is the strongest evidence.
- Under twelve months: expect a projection or a fall back to market rent, and plan for lower leverage.
- Converting from a long-term tenant: the lease and 1007 figure may be the count until hosting history builds.
- Buying a cabin with no history: a projection helps, but the file is reviewed more conservatively.
A common thread on a seasonal cabin: the first year of hosting history often carries a quiet winter. If you convert in the spring, you will not have a clean twelve months until the following spring.
When the Sources Disagree
Say the booking history is strong but the appraiser’s rent opinion is low. Or a projection looks generous against a modest lease. In practice, lenders lean toward the more conservative, better-documented figure. Verified income beats projected income, and a lease beats a guess. Some programs let the stronger documented source control, and some cap it at the lower of the two. That is lender-dependent, which is why the income method should be chosen before the appraisal is ordered.
The same cabin can clear minimum coverage on booking history and fall short on the 1007. The method can decide the outcome.
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.
Cabin-Specific Wrinkles
Cabins carry quirks that a townhouse does not.
- Seasonal road access. If the road is closed or unplowed for months, those months produce little income, and the average shows it.
- Closed or unwinterized months. A cabin shut for the winter counts as zero revenue in those months.
- Owner use. Days you block for yourself are days that earn nothing.
- Resort or HOA dues. They enter PITIA and lower the ratio.
- Insurance. A rental-rated policy can cost more than a personal one, and it lands in the payment.
- Property type. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs. A cabin built as a log home falls outside them.
- Eligibility and legality. 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. If nightly use is not allowed, nightly income cannot count.
Does One Weak Month Sink the File?
No. The ratio is tested on the annual average, not month by month. One slow month lowers the average but does not by itself disqualify the file. A string of them is another matter, because they shrink the yearly total that the lender divides by twelve.
Clearing the Ratio Is Not the Same as Cash Flow
A coverage ratio compares rent to PITIA and nothing else. Repairs, vacancy, management, utilities, and capital costs sit outside the calculation. A cabin can clear 1.00 and still lose money after a roof repair and a slow winter.
Lenders view short-term rentals as operating businesses, which is why they tend to treat them more conservatively than lease-backed rentals. In practice that can mean more equity or tighter terms. Reserves matter here: they are commonly around 6 months of PITIA, and about 9 months on loans above $1,500,000, though they vary by lender, leverage, and transaction type. A cabin with lumpy income deserves a cash cushion for the quiet months.
What the Network Looks Like for Short-Term Rental Files
Across the wholesale network, these are typical ranges, subject to lender guidelines and not a commitment to lend:
- Purchase: up to 75% LTV on a short-term rental.
- Refinance: around 70% LTV.
- Cash-out refinance: 70% LTV on short-term rental collateral, against a 75% ceiling on standard long-term rentals.
- Credit: a 640+ score is typical for short-term rental files.
- History: about 12 months of hosting history.
- Coverage: 1.00 is where select programs start on both purchase and refinance. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Compare that with a long-term cabin lease, where purchase leverage commonly runs 75% to 80% LTV and credit tiers start around a 620 floor in parts of the network. Larger down payments can lift coverage, but they never erase credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
If you may switch the cabin to long-term tenants later, the next lender will count a different rent figure. Plan the exit before you plan the entry.
What to Do If the Counted Number Comes Up Short
A shortfall has a few possible fixes, and it helps to know which kind of shortfall you have.
1. Coverage shortfall: the rent is too low for the payment. Add shoulder-season bookings, tighten your records so every dollar shows, or lower the loan amount with a larger down payment.
2. Equity shortfall: the cabin does not appraise high enough for the leverage you want. More cash down is the usual answer.
3. Switch methods: if booking history is thin, ask whether a lease or a market projection tells a better story.
4. Sub-1.00 path: coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted.
A broker who sees many lenders’ guidelines can match the cabin’s documentation to the program that reads it best. Documentation hygiene, meaning payouts reconciled to deposits and clean statements, quietly raises counted rent more than any other single habit.

Frequently Asked Questions
Will a lender count my peak-season income?
No. Lenders use a full-year average, so a short high season is diluted by every slow month. Plan on the twelve-month total divided by twelve.
Can I qualify on a seasonal cabin with no hosting history?
Sometimes. The file usually falls back to an appraiser’s short-term analysis, a market projection, or the long-term market rent. Expect more conservative treatment, and know that short-term rental programs typically look for about 12 months of hosting history.
Does it matter if the cabin is closed for the winter?
Yes. Closed months count as zero in the average. If the cabin earns well across the open months but sits dark for several, the full-year figure drops accordingly.
Is a 1.00 ratio enough?
It is where select programs start, not a guarantee. Stronger coverage opens better pricing and leverage, and approval depends on credit, reserves, the property, and lender guidelines. Clearing 1.00 also does not mean the cabin cash-flows.
What if my cabin is a log home?
Log homes, manufactured homes, and barndominiums are not offered in the network’s DSCR programs, so that property type would need a different financing route.
