The Quick Read: Yes. A cabin offer should be built so rental coverage clears the program minimum with room to spare, because cabin income is lumpy, lenders trim short-term revenue before they run the ratio, and a file sitting exactly on the minimum has no margin when the appraisal or income analysis shifts even slightly.
- Short-term rental purchase files typically start at a 1.00 coverage floor, with leverage up to 75% LTV on a purchase.
- Lenders count a reduced version of gross booking revenue, not the platform headline.
- Mountain and rural cabin markets often run well below the national occupancy average.
- Clearing 1.00 does not mean the cabin makes money. Repairs, vacancy and management sit outside the ratio.
- The cushion can be built through price, down payment, or the income method you choose.
Key Terms Defined
DSCR (debt service coverage ratio): the property’s qualifying income divided by its full monthly obligation. A result of 1.20 means income covers the obligation 1.2 times.
PITIA: principal, interest, taxes, insurance, and any association dues. It is the obligation the ratio divides into.
Coverage cushion: an editorial term, not an underwriting rule. It means headroom above the program minimum.
LTV (loan-to-value): the loan as a percentage of the property’s value or price. A lower LTV means a bigger down payment.
Trailing 12 months (TTM): a statement of the cabin’s actual booking income over the last year. It shows the slow months along with the busy ones.
Form 1007: the appraiser’s rent schedule. It estimates long-term rent, which often sits below what a good cabin earns nightly.
Why Does a Cabin Need More Headroom Than a Regular Rental?
A cabin needs more headroom because its income swings harder and its underwriting inputs are softer. A year-round apartment collects the same rent in January and July. A cabin does not, and the lender’s number is already a trimmed version of the platform number.
AirDNA defines seasonality as the gap between a market’s lowest and highest monthly average revenue over the past year. Cabin markets tend to have a wide gap. AirROI’s data across ten mountain-cabin markets shows annual occupancy between 30% and 48%. In one Montana ski market the figure was 35%, which means the cabin sits empty most of the year and revenue piles into the winter.
Compare that with the national picture. AirDNA’s midyear outlook expects U.S. occupancy to hold near 57.4%. That is a national average, and a mountain cabin can land far below it. Don’t underwrite a cabin to the national number.
Here’s the catch. A file that works at exactly 1.00 on a generous income figure fails the moment the lender uses a more conservative one. Three things stack against a thin margin:
1. The income gets trimmed. Programs generally count a reduced share of gross short-term revenue before dividing by PITIA.
2. The appraisal can disagree. If a program defaults to the Form 1007 long-term rent figure, a cabin that clears on nightly income can fall short on paper.
3. Pricing follows the ratio. Stronger coverage generally opens better pricing and leverage tiers. A cushion protects the approval and can improve the terms.
What Coverage Do Programs Actually Ask For?
Short-term rental purchase files across the wholesale network typically start at a 1.00 coverage floor, and refinance files also start at 1.00. Those are separate program lines, not one blended number. Leverage tops out around 75% LTV on an STR purchase, and cash-out on short-term-rental collateral generally stops near 70%.
Other thresholds matter just as much. Most STR programs look for a credit score of about 640 or higher and roughly 12 months of hosting history. Loan sizes run up to $3,000,000 on standard programs. Reserves vary by lender, leverage and loan size, and commonly land around six months of PITIA.
Coverage below 1.00 is a different path. It is available through select lenders in the network, with leverage and terms adjusted. It is not simply the same program with a lower floor. Plan the offer around the standard path, and treat sub-1.00 as a fallback with tighter restrictions.
One property-type note matters for cabins specifically. DSCR Investor Loans through the network is not offered on log homes, manufactured homes, or barndominiums. A cabin built as a log home falls outside these programs. Check construction type before you write an offer.
For the full program picture, see Lendmire’s complete DSCR loans guide. These figures are typical ranges from select lenders, subject to lender guidelines, and not a commitment to lend.
How Does the Income Method Change the Cushion?
The method used to count income can move the ratio more than the purchase price does. Lenders typically look at one of four sources:
- The appraiser’s short-term rental income analysis
- A trailing-12-month statement from the platform
- Bank-statement deposits
- A market projection from a data service such as AirDNA or Rabbu
A trailing year is the most honest document because it includes the trough. Awning’s summary of AirDNA data puts occupancy in mountain, rural and highly seasonal markets at about 40% to 55%. That is a vendor summary, so treat it as directional. The point stands. A full year of statements captures those slow months, and a peak-season screenshot does not.
A new purchase has no history. The file then leans on a projection, and a projection is unproven. AirDNA says its own estimates are built from the booking patterns, pricing and seasonal demand of comparable active rentals. That is a reasonable method, but it is still a forecast. A cabin with no operating record is where the cushion matters most.
Ask each lender which method it uses before you write the offer. In the files Lendmire places, this question alone often separates a clean approval from a surprise at appraisal.
What Does a Seasonal Cabin Look Like Quarter by Quarter?
The annual ratio hides the weak months. Here is a modeled example, built from assumptions rather than market data. It shows why a cabin can look fine on paper and still strain the owner.
| Season | Modeled coverage | What it means |
|---|---|---|
| Peak (ski or leaf season) | About 1.6x | Income well above obligation |
| Shoulder | About 1.0x | Income roughly equals obligation |
| Off-season | About 0.5x | Income covers half the obligation |
A lender reviews the file on the annual picture, so this cabin might pass. But the owner still pays the full PITIA in the off-season months. If the cushion is thin, a bad winter or a slow shoulder season drains reserves.
This is why the cushion is not only an approval tool. It is the margin that lets you carry the quiet months. Lendmire’s piece How to Show Seasonal Short-Term-Rental Income as Steady DSCR Coverage covers how to present the annual picture to a lender.
Does Cabin Size Change the Cushion?
Size changes it, though not always in the direction people expect. AirROI’s breakdown of one Tennessee cabin market shows trailing revenue climbing steeply as bedroom count rises. Larger cabins can offer more headroom against PITIA. Occupancy tends to dip slightly as size rises, though, and bigger cabins carry bigger operating costs.
Treat that as a reason to model the specific cabin, not a rule to buy big. A large cabin with thin occupancy can have a worse cushion than a modest one that books steadily.
How Big Should the Cushion Be?
No source defines a required cushion. The honest answer is a range of judgment, not a formula. Here is how a broker thinks about it.
At exactly the program minimum, the file has no margin. A small appraisal change can push it under. Modest headroom above the minimum survives ordinary surprises. Stronger coverage opens better pricing and leverage tiers, which is why many investors aim well above the floor on a cabin.
For a seasonal cabin with no history, aim higher than you would for a year-round rental. The more your income depends on a projection, the more margin you want.
Remember the limit of the ratio, too. DSCR compares rent to PITIA only. Repairs, cleaning, utilities, management, and slow months sit outside the calculation. So a cushion on the ratio is not the same as positive cash flow. Keep a separate operating reserve on top of it.
Turning the Cushion into an Offer
The cushion becomes real in the offer through three levers: price, down payment, and contingencies. Here is how they map to the cushion you can show.
| Cushion on lender’s number | Price lever | Down payment lever | Contingency lever |
|---|---|---|---|
| Thin | Offer lower or walk | Plan for more down | Add income and rental-rule contingencies |
| Adequate | Offer near asking | Standard leverage | Keep rental-rule check |
| Strong | Room to compete | Can use higher leverage | Fewer needed |
A larger down payment lowers the monthly obligation and can lift the ratio. It does not erase the leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
For the price side of the decision, Lendmire’s article How to Set a Maximum Offer Price on a Short-Term Rental Cabin walks through the walk-away number.
Rules come first, though. 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. A cabin you cannot legally rent has no coverage at all.
How Do You Stress-Test Before You Submit?
Run the cabin through a bad year before you commit. Lower the occupancy, add a major repair, and raise the costs the mortgage payment hides, such as septic, well, road dues, propane, and a hot tub. Then ask whether the cushion survives.
A simple test works. Drop your income estimate until the ratio sits near the program minimum. If that drop is only a small cut, the offer is too thin. If it takes a large drop, the cushion is real.
Do the same for the seller’s numbers. A seller’s gross revenue is not owner income, and one strong year can mislead. Ask for monthly revenue, occupancy and average daily rate, then compare them with the lender’s method and your conservative version. Three different incomes for one cabin is normal.
Tax treatment varies; consult a qualified professional.
Frequently Asked Questions
Is 1.00 coverage enough on a cabin?
It can meet a program’s starting floor, but it leaves no margin. A cabin’s income is seasonal and often trimmed before the ratio is calculated. Most investors do better offering at a price that clears 1.00 with room to spare, subject to lender guidelines.
Does a bigger down payment replace the cushion?
No, but it helps. More down lowers the monthly obligation and can lift the ratio. It does not override leverage caps, credit floors, reserve rules or property eligibility. Short-term rental purchases typically top out near 75% LTV.
Can I buy a cabin with no rental history?
Often, yes, though the file leans on a projection rather than a trailing year. Programs also expect about 12 months of hosting experience from the borrower. Because projections are unproven, build in more cushion.
What if the ratio comes in below 1.00?
Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. It is a separate path from the standard 1.00 programs. Eligibility review depends on credit, reserves and the property.
Does the ratio tell me if the cabin will make money?
No. The ratio covers principal, interest, taxes, insurance and dues only. Repairs, vacancy, management and utilities sit outside it, so keep a separate operating cushion.
