The Quick Read: You qualify by finding out why the number fell, then rebuilding coverage with better income evidence or a smaller loan. A lower projection cuts qualifying income one-for-one, so the fix is usually correcting inputs, documenting actual income, or restructuring the deal.
- A projection is evidence, not the coverage figure. The lender applies its own income method and haircut.
- Across most programs in Lendmire’s network, short-term rental files start at 1.00 coverage on both purchases and refinances.
- Short-term rental purchases reach up to 75% LTV, and refinances up to 70%, subject to lender guidelines.
- A projection can drop for fixable reasons, such as a weak comp set or a wrong bedroom count.
- Run the deal at a lower projection before you go under contract, not after the appraisal.
Why a Lower Projection Changes the Loan
A lower projection shrinks the income the lender can count. At a fixed payment, that lowers coverage and can shrink the loan the property supports. Understanding the mechanics tells you which fix to try first.

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.
A DSCR loan (debt service coverage ratio loan) is an investor loan that qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. For a short-term rental with no operating history, a third-party projection often supplies that income. The best-known projection tool is AirDNA’s Rentalizer. It estimates annual revenue, average daily rate, and occupancy for an address.
The tool builds that estimate from comparable short-term rentals within a 10-mile radius. It matches them on bedroom, bathroom, and guest count, and it adjusts for seasonality and demand. It also reports a Comp Set Strength score of Low, Medium, or High.
That means the projection is not fixed. It moves when the comp set, the property inputs, or the seasonality data change. A drop can come from any of them.
What “the Projection Dropped” Actually Means
“Dropped” covers several different situations, and each has a different owner and a different fix. Sort yours before you react.
| Scenario | What changed | Who controls it | What to do |
|---|---|---|---|
| Report refreshed | Comps or seasonality updated | Data vendor | Re-check comps and inputs |
| Lender pulls its own | Different tool or settings | Lender | Ask which inputs it used |
| Appraiser’s analysis is lower | Appraiser used different comps | Appraiser and lender | Request a narrative review |
| Wrong property inputs | Bedrooms, baths, or guests off | You | Correct and re-run |
| Slow stretch in history | Trailing months include off-season | Market | Document the full 12 months |
Only the third and fifth rows involve things you cannot change directly. The others are corrections, and corrections are usually the more affordable fix.
Step One: Diagnose Which Input Moved
Open the report and compare it to the earlier version. Check three things in order.
1. Comp Set Strength. AirDNA says accuracy depends on whether the tool captured what actually happened and whether the right comps were chosen. A Low score suggests thin or mismatched comps. Rural and unusual properties tend to land here.
2. Property attributes. Confirm the bedroom count, bathroom count, and guest capacity. A mislabeled bedroom puts you in the wrong comp pool.
3. Rate versus occupancy. Find out whether nightly price or occupancy fell. A market-wide softening needs a different response than a bad comp.
The tool lets you correct property details or hand-pick the comp set. Doing that is legitimate when the original comps genuinely do not match your property. Shopping for a better number by changing inputs until the report flatters you is something else. Lenders notice stacked reports and inflated inputs, and it weakens the file.
How Underwriting Treats the Number, Step by Step
Here is how a lender actually handles a short-term rental income figure. Programs differ in the details, which is why Lendmire sees so much variation across the lenders in its wholesale network.
1. The lender chooses the evidence. Common paths are an appraiser’s short-term rental analysis, a 12-month property-manager statement or platform export, 12 months of bank statements, or a third-party projection when there is no history. McKissock notes that lenders make the final call on income from all sources, including short-term rentals.
2. A haircut comes off gross revenue. BiggerPockets reports that lenders typically apply an expense factor of about 20% to 25% to gross short-term rental income. Within Lendmire’s network, the size and method vary by program, so ask each lender how it applies the haircut.
3. The result is divided by PITIA. PITIA is principal, interest, taxes, insurance, and any HOA dues. That is the whole denominator.
4. The loan is sized to the tighter of two tests. One test is the LTV cap. The other is the largest loan at which the haircut income still clears the coverage floor. A lower projection tightens the second test first.
5. The appraisal returns value and a rent schedule. The standard forms are the 1007 for one unit and the 1025 for two to four units.
The haircut is not a judgment on your revenue. Think of it as a stand-in for the operating costs that the payment does not include.
A Quick Look at the Appraisal Form
Fannie Mae’s appraiser guidance says the 1007 documents estimated monthly market rent on a single-family investment property. It relies on monthly-lease comps. This is appraisal-form context only, because DSCR loans are not agency loans.
The practical point is that the form measures monthly rent, not nightly rates. The form documents monthly rent, not nightly rent or business income. HousingWire reports that using the 1007 for short-term rental income often distorts DSCR calculations and produces artificially low ratios.
So if a file falls back to the appraiser’s rent schedule, coverage can come in low even when the property performs well. Whether a file falls back to long-term rent depends on the program.
Three Ways to Document Income
If the projection is the problem, change the evidence. Each method proves something different.
| Method | When it applies | Strength | Weakness when projection falls |
|---|---|---|---|
| Booking history | Property already operates | Real revenue | Slow months drag the average |
| Projection | No history, such as a purchase | Forward-looking | It is the number under attack |
| Appraiser’s long-term rent | Fallback | Hard to dispute | Usually the lowest income |
Actual history often beats a projection on an operating property. A 12-month manager statement or platform export is concrete, and lenders can test it against bank deposits. A high performer that far exceeds its submarket may still draw a tighter ratio, so expect scrutiny.
For two-to-four-unit properties, the 1025 form includes a unit-by-unit rent schedule. Part of the income may then come from long-term leases rather than nightly bookings.
Some lenders also accept mid-term rental income, meaning stays of roughly a month or more. Acceptance varies by lender, so treat it as a possible alternate path rather than a given.
What the Math Looks Like
The math is simple once you see it. These figures are modeled assumptions, not market data.
Say a short-term rental clears 1.30 coverage on the lender’s haircut income. Then the projection falls. Because the payment stays fixed, coverage drops by the same percentage as income.
| Projection falls by | Modeled coverage | Against a 1.00 floor |
|---|---|---|
| 0% | 1.30 | Clears |
| 10% | 1.17 | Clears |
| 20% | 1.04 | Clears, barely |
| 25% | 0.98 | Falls short |
Break-even sits near a 23% decline in this model. Start the same file at 1.20 coverage and break-even moves to roughly a 17% decline. The thinner your starting cushion, the less a projection drop can absorb.
Note the limit of this math. Clearing 1.00 is not the same as positive cash flow. DSCR compares rent to PITIA only. Vacancy, management, utilities, repairs, and capex sit outside the calculation, and short-term rentals tend to carry heavier operating costs than long-term rentals.
The Levers You Can Pull
When coverage slips, work through the levers in order of cost to you. Start with the free ones.
| Lever | Effect on coverage | Tradeoff |
|---|---|---|
| Correct inputs and comps | Can restore the original number | Must be genuine |
| Check a second data source | Tests the first report | Another number can also be lower |
| Request an appraiser’s short-term rental analysis | May reflect the property better | Appraiser’s call |
| Use trailing 12-month actuals | Replaces projection with real data | Needs operating history |
| Reduce the loan amount | Lowers the payment, lifts coverage | More cash down |
| Renegotiate price | Shrinks the loan at the same LTV | Seller must agree |
| Change the term structure | Can lower the payment | Different terms, subject to lender review |
A smaller loan helps in a direct way. Cut the payment by 10% and a file at 1.04 moves to about 1.16. That is a modeled example, but the direction holds on real files.
Term structure matters too. The 30-year fixed is the spine of most programs. Extended terms such as 40-year and interest-only periods are available through select lenders in the network, and ARM structures exist for investors who want them. Each choice changes pricing and eligibility, so a lender must review it.
A larger down payment lowers the payment and can lift coverage. It never erases the leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Where the General Rule Breaks
The step-by-step flow above covers most files. These edge cases bend it.
The projection was understated. Projections miss in both directions. A lower figure than your property actually earns is a reason to document actuals, not to accept the haircut on a bad estimate.
Thin comps. Rural and unusual properties often have few true comparables. A weak comp set can usually be corrected by hand-picking comps in the tool.
Short-term rental rules. 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 short-term use cannot be supported, the long-term rent schedule becomes the only ratio.
No history on a purchase. Without booking history, a projection is usually the starting point. Many lenders then want the appraiser’s analysis to land near it.
Different lenders, different answers. Some lenders rely on the appraiser’s form, some on the projection, and some on both at their discretion. That variation is exactly why a file can fail with one lender and work with another.
Not offered. DSCR on manufactured homes (single- and double-wide), log homes, and barndominiums is not offered in the network. No income fix changes that.
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.
Program Numbers to Hold in Mind
Here are the numbers Lendmire sees across its wholesale network for short-term rentals. Treat them as typical ranges, subject to lender guidelines, not promises.
- Purchase leverage: up to 75% LTV on the strongest files.
- Refinance leverage: up to 70% LTV on short-term rental collateral.
- Cash-out: around 70% LTV on short-term rental collateral, against about 75% on standard long-term rentals.
- Credit: a 640 minimum score for short-term rentals.
- Experience: about 12 months of hosting history is typical.
- Coverage: 1.00 on purchases and refinances for short-term rentals, as separate floors.
- Loan size: up to $3,000,000 on standard programs.
- Reserves: vary by lender, leverage, loan size, and transaction type, and commonly sit around 6 months of PITIA.
A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. That route is available through select lenders in the network. It is a different program, not a lower floor on the same one, and eligibility depends on the file.
For the full picture of how these programs fit together, see the complete DSCR loans guide.
Run It Before You Go Under Contract
Experience tells you more than any tool here. Investors often model a property at peak season, while lenders haircut and underwrite lower. A beach rental that earns heavily in July and very little in February averages out to far less than the summer number suggests.
Model the deal at a projection 20% to 25% below the report before you sign. If coverage still clears the floor, the file has room. If it does not, you have two good options: negotiate the price, or plan for more cash down.
Time matters as well. Pull the report before you make an offer and again before the appraisal. Rework the offer around a lower number before the appraisal, not after. Lendmire’s piece Can a Short-Term Rental Still Close on DSCR if the Projection Drops? covers the late-stage scenario. For the negotiating side, read the guide How to Rework a Short-Term Rental Offer When the Projection Falls.
A practical order of operations looks like this:
1. Diagnose which input moved.
2. Correct any wrong inputs and re-run.
3. Compare a second data source.
4. Supplement with actual documents, if the property operates.
5. Restructure the loan or change the price.
6. Walk away or switch methods if coverage still fails.
What Not to Do
- Do not inflate inputs. Adding a bedroom or guest count the property does not have invites a failed appraisal.
- Do not stack reports. Pulling five projections and handing over the best one looks like shopping, and it weakens credibility.
- Do not multiply a nightly rate by 30. The appraisal form does not work that way.
- Do not treat DSCR as a profit test. Passing the ratio does not mean the property cash flows.
- Do not skip the downside run. Test a lower number before you commit.
Tax treatment varies; consult a qualified professional before relying on any deduction.
Documents to Gather for an Alternate Income Path
If you move off the projection, assemble the following:
- Twelve months of platform payout reports or a manager statement.
- Matching bank statements that show the deposits.
- Forward reservations, if the property has them.
- Insurance and HOA figures, since both affect PITIA.
- Any appraiser’s short-term rental analysis ordered on the file.
Key Terms Defined
DSCR: the ratio of qualifying income to the full monthly obligation on the property.
PITIA: principal, interest, taxes, insurance, and HOA dues, which together form the denominator of the ratio.
Haircut: the percentage a lender removes from gross short-term rental income before running the ratio.
Comp set: the group of comparable rentals a projection tool uses to estimate income for your address.
Form 1007 / Form 1025: appraisal forms that document market rent, the first for one unit and the second for two to four units.
LTV: loan-to-value, the loan amount as a share of the property’s value.
Frequently Asked Questions
Can a lender use a different projection than the one I pulled?
Yes, lenders can pull their own or lean on the appraiser’s analysis. Some use the appraisal form, some the projection, and some both at their discretion. Ask early which source the lender will use, and give it any corrections to the comp set or property details.
Can I use actual bookings instead of the projection?
Often, if the property has operating history. A 12-month manager statement or platform export, matched to bank deposits, is concrete evidence. Programs typically expect about 12 months of hosting experience on short-term rental files, subject to lender guidelines.
What if coverage falls below 1.00?
Then 1.00 programs will not work as structured. You can also shrink the loan, renegotiate the price, or document stronger income. Eligibility depends on the file.
Does a refinance work differently from a purchase?
Yes. A refinance on an operating property can lean on real history instead of a projection. Short-term rental refinances run up to about 70% LTV in the network, against up to 75% on a purchase, subject to lender guidelines.
Is a passing DSCR the same as positive cash flow?
No. The ratio compares rent to PITIA only. Vacancy, management, utilities, repairs, and capex sit outside it, so run your own operating budget separately.
