The Quick Read: When actual bookings land below the projection, the coverage figure follows the evidence the lender accepts. That means documented trailing history on an operating rental, a market projection or appraiser analysis on a purchase with no history, and a long-term-rent fallback where the program allows it. A projection is for buyers who have no track record yet. Actual history is for owners who do. After a drop, the second kind of file shows the drop in black and white.
- A purchase usually has no history under the buyer, so a projection or appraiser analysis carries the file.
- A refinance of an operating short-term rental usually runs on documented history, and that history includes the decline.
- Across our wholesale network, STR purchases go up to 75% LTV and STR refinances and cash-outs up to 70%, subject to lender guidelines.
- Clearing a 1.00 coverage floor is not the same as making money. Repairs, vacancy, management, and utilities sit outside the ratio.
- Which figure controls when the two disagree depends on the program, so confirm it before you write an offer or apply.
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.

Side-by-Side
Here is how the two income bases compare on the file. Both are used on short-term rental DSCR loans. The details below reflect typical ranges across select lenders in our network, and every file is underwritten individually.
| Factor | Projection-Based | Actual-History-Based |
|---|---|---|
| Review basis | Estimated STR income for the property | Documented trailing income from the property |
| Documentation | Market report or appraiser STR analysis | Platform payouts, manager reports, bank deposits |
| Typical use | Purchase, conversion, first-time host | Refinance or cash-out of an operating STR |
| Effect of a drop | May still reflect an earlier, stronger period | Records the drop in full |
| Leverage (STR) | Purchase: up to 75% LTV | Refinance or cash-out: up to 70% LTV |
| Credit and hosting | 640 minimum; about 12 months of host experience | Same expectations; history is the proof |
| Property types | Manufactured, log, barndominium not offered | Same eligible property types |
| Entity vesting | LLC vesting often available per program terms | Same, with statements matched to the entity |
| Reserves | Commonly around 6 months of PITIA, varies | Same range; varies by file |
Key Terms Defined
DSCR (debt service coverage ratio) is the property’s monthly income divided by its monthly housing payment. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
PITIA is principal, interest, taxes, insurance, and HOA dues if any. It is the payment in the denominator.
Projection is an estimate of what the property should earn, built from a market-data report or an appraiser’s STR analysis.
Trailing actual income is what the property really collected, usually over the most recent twelve months, shown by platform or manager records.
Expense factor (haircut) is a percentage some programs subtract from gross STR income before running the ratio.
Form 1007 is the appraiser’s long-term rent schedule for single-family homes. Form 1025 is its counterpart for 2-4 unit properties.
LTV (loan-to-value) is the loan balance as a percentage of the property’s value.
Why the Two Numbers Diverge
Projections and actuals split apart for ordinary reasons. Most are not a sign the deal is broken.
- Comp mismatch. The estimate may lean on listings with more bedrooms, better views, or stronger reviews than your property.
- Ramp-up. A new listing needs reviews before it can price like the established ones.
- Seasonality. A short window can overstate a peak or understate a slow stretch. A full twelve-month window captures the whole cycle.
- Market softening. AirDNA’s U.S. outlook projects occupancy slipping, with average daily rate growth slow but positive. It also shows a trailing twelve-month occupancy low of 56.5% later in the forecast window. That is a market forecast, not a program figure, and individual properties can run above or below it.
- Gross versus net. A projection may count revenue before platform fees and cleaning costs that a bank statement never shows.
A drop can be temporary or structural. A closed road, a renovation, or a few cancelled months is one thing. A new competing supply pool, or an overpriced listing, is another. Underwriters look at which story the documents tell.
When Projection Is the Better Fit
A projection is the right tool when no history exists under your name. That covers three cases.
A purchase with no operating record. There are no statements to show. The lender leans on a third-party market report, an appraiser’s STR analysis, or the long-term rent schedule. This is the usual home of the projection.
A conversion. You are turning a long-term rental into a short-term one. AvantStay, a vacation-rental operator, suggests pairing projections with local context such as attractions and competing listings for this case. History is not available, so context has to fill the gap.
A buyer inheriting the seller’s records. Some programs let a buyer use the seller’s documented history. Others do not. Ask before you count on it.
Appraiser methods deserve a caution. Class Valuation, an appraisal firm, argues that Form 1007 cannot support short-term rental income. It says a proper STR analysis is a labeled narrative addendum with market-supported occupancy and seasonal pricing. That is one firm’s position, not a rule. Still, it is a fair warning that the long-term rent schedule is often well below STR potential.
A projection also has a hidden weakness after a drop. If it was built from older, stronger data, it can overstate what the property earns today. Smart buyers discount their own projection before the lender does.
When Actual History Is the Better Fit
Actual history wins when you already operate the rental and the records are clean. That is most refinances and cash-outs on a running Airbnb or Vrbo.
AvantStay describes actual income history as carrying more weight than projections for a property already operating as an STR. That matches how we see files read across the network. Documented bookings are harder to argue with than a model.
History is a double-edged sword after a drop, though. The trailing window captures the decline. You may qualify on less income than the original projection suggested. Three things matter in that file:
1. The documents must reconcile. Payout statements, manager reports, and bank deposits should tell the same story.
2. The window matters. A full twelve-month view smooths seasons. A shorter one can flatter or punish you.
3. Vacant months count. Months with no bookings are part of the average. They do not disappear because the cause was a repair or a closure.
Choosing history also changes which tier you are in. STR refinances go up to 70% LTV, and STR cash-outs also top out at 70% on short-term-rental collateral. Standard long-term rentals reach 75% on cash-out. So a drop that pushes you onto the long-term rent fallback can change the leverage conversation, not just the ratio. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Which Number Does the Lender Use?
On a purchase, the choice is usually among a projection, an appraiser analysis, or the long-term rent. On a refinance with history, trailing actuals usually lead.
When projected and actual figures differ, programs behave differently. Some use the lower supported figure. Others let the borrower choose the stronger one. No neutral rule sets a universal tie-break, so this is the first question to put to your broker. Across our wholesale network, you will find both approaches. Different lenders read the same property differently, which is why shopping the file matters.
Every program applies its own ratio definition too. Some use gross income over PITIA, and others use net operating income over a narrower payment. Do not assume your last ratio transfers to the next lender.
Lendmire’s piece STR income vs long-term rent fallback for a first-time Airbnb DSCR buyer walks through that fallback choice for first-time buyers.
A Worked Example: One Property, Four Views
These are modeled assumptions, not market data. Picture a short-term rental whose projection clears coverage comfortably, and watch the ratio move.
- Projection at purchase: about 1.35x. It clears the 1.00 floor with room.
- Actual after a drop: about 0.95x. The same property now sits just under 1.00 on documented income.
- Blended stress case: about 1.15x. This is a midpoint you run yourself, not something every lender will accept.
- Long-term rent fallback: about 0.85x. This is where the 1007 often lands against STR potential.
Same house, four answers. The projection would have qualified. The actual figure sits just below the 1.00 floor that STR files need on a purchase and, separately, on a refinance. Coverage of 1.00 is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. That path is not available on every property type, so treat it as an option to explore, not a plan.
The expense factor adds another layer. Suppose a program applies a 20% factor to gross income. A gross ratio of 2.00 becomes 1.60 after the factor, because 2.00 times 0.80 is 1.60. That is a modeled illustration. Some programs apply no such factor, and others apply a different one.
How Far Can Income Fall?
Run this stress test before you buy. Start with a file at 1.40x coverage and see where it breaks.
| Income Drop | Resulting Coverage | Against a 1.00 Floor |
|---|---|---|
| 10% | 1.26x | Clears |
| 20% | 1.12x | Clears |
| 30% | 0.98x | Falls just short |
| 40% | 0.84x | Falls short |
A file at 1.40x breaks 1.00 after an income decline of a little more than 28%. A file at 1.10x breaks after about 9%. Thin cushions at purchase become real problems after one soft year.
A larger down payment can help. It lowers the monthly payment and can lift the ratio. But it never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
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.
What to Do After a Drop
If your actuals trail your projection, work through these in order.
1. Find the cause. Separate one-off events from structural ones. Write down which it is.
2. Pull clean records. Platform payouts, manager reports, and bank deposits should match line by line.
3. Run the file on both bases. See the trailing ratio and the long-term rent ratio side by side before you talk to anyone.
4. Ask which figure controls. The answer varies by program. Get it before you apply.
5. Consider restructuring. A smaller loan or a larger down payment may lift coverage. Extended terms such as 40-year and interest-only periods are available through select lenders in the network. Those change the payment, not the property’s income.
6. Consider timing. If a temporary event hit your trailing window, a later look at the same property may read better. Do not time anything around a promise.
Lendmire’s article AirDNA Projections vs Airbnb Statements for a First-Time STR Buyer covers the evidence question in more depth.
Explaining the Drop
Underwriters read narrative as well as numbers. A short, factual note helps when the cause is documented: a renovation, a road closure, a local event, or a platform suspension. It does not erase the numbers. It tells the reviewer why they look the way they do.
Ratio Versus Real Cash Flow
Clearing the ratio is not positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management fees, utilities, cleaning, supplies, and capital replacements are outside the calculation.
A short-term rental has more of those costs than a long-term lease. So a file can pass at 1.10x and still lose money in a slow season. Before you rely on a coverage number, build your own owner budget:
- Vacancy and seasonal troughs
- Management or your own time
- Utilities, supplies, and cleaning turns
- Repairs and furniture replacement
- A capital reserve
Keep it on paper beside the lender’s ratio. The lender’s number answers whether the loan fits. Your budget answers whether the investment does.
Documentation Checklist
For the actual-history route, gather these:
- Airbnb or Vrbo payout statements for the full trailing window
- Property-management reports, if a manager runs the unit
- Bank deposits that reconcile to those statements
- A short explanation of any low or vacant months
- Proof of host experience, since STR files usually expect about 12 months
For the projection route, gather:
- A market report matched to bedrooms, baths, and guest count
- The appraisal and any STR analysis addendum
- Your own comp notes on competing listings
Documents shift from personal income to property income. They do not vanish.
The Verdict
Neither basis is better in the abstract. A projection suits the buyer with no history, and it is only as good as its comps. Actual history suits the operating owner, and it is only as flattering as the last twelve months.
After a drop, history is the more honest picture. It is also the harder one to qualify on. If you are buying, run your deal on the lower of the two numbers, then test it against the long-term rent. If you already own, document the cause and see what coverage the trailing figures support.
Whichever basis applies, model a 20% to 30% income decline before you commit. A deal that survives it has room for the next soft season. A deal that does not is a bet on the projection.
Frequently Asked Questions
Can the lender use the projection if my bookings are lower?
It depends on the transaction and the program. On a purchase with no history, a projection or appraiser analysis is often the evidence. On a refinance of an operating rental, documented history usually leads. Some programs use the lower supported figure and others let you choose the stronger one.
Does one bad season sink the loan?
Not necessarily. A full twelve-month window averages across seasons, so one weak stretch lowers the figure without deciding it. What matters is whether the resulting coverage still clears the program’s floor. A cushion at purchase is what lets a bad season be survivable.
Do vacant months count as zero?
Yes, they enter the average as zero income. A documented reason, such as a renovation, can help the reviewer understand the gap, but the months still count. Present them honestly instead of hiding them.
Does clearing 1.00 mean the property makes money?
No. The ratio compares rent to PITIA only. Vacancy, repairs, management, utilities, and capital costs are not in it. A property can clear coverage and still run at a loss.
Can I fall back to the long-term rent instead?
Some programs allow it. The appraiser’s rent schedule often comes in well below STR potential, so the fallback may be the only workable number or may not matter if it still clears the floor. Whether it is available depends on the program.
