The Quick Read: A new build has no booking history, so the lender relies on projected income, usually a third-party short-term-rental report or an appraiser’s analysis, and tests it against the full monthly housing payment once the home is finished and has a certificate of occupancy. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
- A DSCR loan is take-out financing for a finished home. It does not fund the build.
- Projections are reviewed, and programs may discount them before the ratio is run.
- Short-term-rental purchases typically reach up to 75% LTV, with a 640 minimum credit score.
- The long-term market rent from the appraiser is the usual fallback if the projection fails.
- Clearing the coverage floor does not mean the property cash flows.
Picture an investor with a builder contract on a four-bedroom home near a lake. No guest has ever booked it. The lender cannot see twelve months of Airbnb statements, so the file has to prove the income another way. This guide walks through how that works, step by step.

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 Does DSCR Actually Measure on a Short-Term Rental?
DSCR stands for debt service coverage ratio. It compares the property’s income to its housing payment. On a residential file, the lender divides monthly rental income by PITIA, which is principal, interest, taxes, insurance, and association dues. A result of 1.00 means income equals the payment. Higher means more cushion.
On short-term rentals, the income figure is the hard part. Nightly rates and occupancy move with seasons and demand. So lenders look harder at how you arrived at the number. For short-term-rental collateral, most programs we place files with start at a 1.00 coverage floor on purchases, and the same 1.00 applies to refinances. Some select lenders in the network will review coverage below 1.00, with leverage and terms adjusted. That is a separate path, not a softer version of the standard one.
Here is the catch. DSCR counts rent against PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the ratio. Short-term rentals carry heavier operating costs than long-term leases, so a passing ratio is not a promise of profit.
Key Terms Defined
- Projection: an estimate of a property’s future rental income, built from nearby comparable listings rather than the property’s own history.
- ADR: average daily rate, the typical nightly price a booking earns.
- Occupancy: the share of available nights that are actually booked.
- Certificate of occupancy (CO): the document from the local building department saying the finished home may be lived in.
- Form 1007: the appraiser’s rent schedule, which estimates long-term monthly market rent on a one-unit property.
- Take-out financing: a permanent loan that pays off or replaces short-term construction money once the home is done.
What Makes a New Build Different?
A new build stacks two estimates on top of each other. The appraiser must set a value with limited comparable sales. And the lender must accept income that has never been earned. Either one alone is routine. Together they deserve preparation.
Existing rentals bring statements, calendars, and tax records. A new build brings a contract, plans, and a forecast. That shifts the burden onto the quality of your evidence. A clean, conservative projection with well-matched comps helps. A builder’s marketing sheet does not.
How Does Underwriting Treat Projected Income, Step by Step?
Most files follow the same path. Each step has a purpose.
1. Sequence the build and the loan. A construction or builder loan, or your own cash, carries the project. The DSCR loan comes after completion, once a CO or equivalent exists. A temporary CO can bridge a delay in some cases. Lendmire’s own piece New Build vs Existing Rental: DSCR for LLC Portfolios covers this sequencing in more detail.
2. Pull a projection. The usual tool is an AirDNA-style report run on the subject address. AirDNA says its Rentalizer calculator weights nearby comparable listings by similarity, and factors in seasonality, demand, and revenue growth. It returns projected annual revenue, ADR, and occupancy, plus a score showing how consistent the comps are.
3. Order the appraisal. The appraiser opines on value and market rent. For a one-unit home that rent opinion sits on Form 1007, the single-family comparable rent schedule. Two-to-four-unit properties use a counterpart form, described in Lendmire’s complete DSCR loans guide. Whether a separate short-term-rental analysis is also ordered depends on the program.
4. Apply the program’s income treatment. The program takes the projection and may discount it, then divides the adjusted monthly figure by PITIA. The size of the discount varies by lender, which is why one file can produce different ratios at different programs.
5. Close on completion. The file typically needs the CO, final inspection, and permanent hazard insurance. Builder’s-risk coverage may not satisfy the permanent-loan requirement.
A CO does not equal approval. The lender still reviews value, rent, condition, insurance, and title.
What Are the Three Income Methods?
Underwriters generally look at three kinds of evidence. A new build uses the second or third.
| Method | When it applies | New-build fit |
|---|---|---|
| Actual host history | Existing STR with records | Not available |
| Third-party projection | Purchase, no history | Primary path |
| Appraiser rent schedule | Fallback or conservative path | Common backup |
Across our wholesale network, programs differ on which method they prefer and how much they discount the projection. Some lean on the third-party report. Others weigh the appraiser’s figure more heavily. The practical lesson: ask which method a program favors before you pick one.
Why Can’t the AirDNA Number Just Be Your Qualifying Income?
Because projections are estimates, and they can run high. Vault STR, a third-party analytics blog, says independent tests put Rentalizer 15-30% off actual results, usually on the high side, and suggests underwriting year one at 60-75% of the projection. That is one analyst’s opinion, not a standard. Still, it reflects why programs discount.
A single test cuts both ways. Chalet’s comparison found AirDNA close on total revenue, at $69,500, but with the wrong mix: it assumed 79% occupancy and a $242 ADR, against an actual 70% and $310. The total landed, but the pieces did not. One case proves little, but it shows why lenders look at the components.
On blocked calendars, which Vault blames for part of the optimism, AirDNA’s own help page says blocked nights are excluded from occupancy. Occupancy there is reserved days divided by active listing nights over the last twelve months.
How Do You Build a Projection a Lender Will Respect?
Treat it like a case you are making. Four habits help.
Match the comps to your actual house. Bedroom count, guest capacity, and amenities should line up. A hot tub on the comps but not on your plans overstates income. In a new subdivision with few comps, a wider radius is common, so expect the lender to ask how similar the added comps are.
Drop outliers. One listing that books at a premium can pull the average. Strip it out.
Ignore the builder’s pro forma. A marketing sheet or a listing’s advertised nightly rate is not a coverage figure. Replace it with a report on your own address.
Reconcile the sources. The appraiser’s figure, the third-party report, and your own forecast will rarely match. Expect the lender to use the program’s chosen source, often the more conservative one. Know all three before you apply.
Revenue in these reports is booked days times ADR, and AirDNA’s help center says it includes the cleaning fee and excludes platform host fees. Keep that in mind when comparing a report to your own spreadsheet.
Worked Example: A Pass and a Near-Miss
These are modeled assumptions, not market data. Say a new-build cabin is priced at $450,000 and purchased at 75% LTV, the short-term-rental purchase ceiling. The lender’s discounted projection gives a coverage ratio around 1.25x. That clears the 1.00 floor with room to spare. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Now run the same house with a more conservative discount, and say the ratio falls to roughly 0.95x. It misses the floor. The investor has options, which a lender would review: a lower LTV to shrink the payment, the appraiser’s long-term rent as an alternate income method (usually lower, so only if it helps), or a select-lender path that takes coverage below 1.00 with leverage and terms adjusted. Qualification stays subject to credit approval and property review.
Honestly, the near-miss is the more useful scenario. Most new-build files do not fail on one big number. They fail by a few hundredths of a ratio point because someone assumed the optimistic comp set.
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.
Stress-Test Before You Apply
Run your own sensitivity check. Take the projection, then cut occupancy by 10 points, then cut ADR by 10%, then do both. See where coverage lands. If a modest haircut breaks 1.00, the deal is thin, and a lender’s discount will find it.
Also remember that a larger down payment lowers the payment and can lift the ratio. It does not erase credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough coverage. Short-term-rental files typically want a 640 or higher score. Reserves vary by lender, leverage, and loan size, commonly around six months of PITIA, and standard programs reach loan amounts up to $3,000,000. These are typical ranges from select wholesale-network guidelines, not promises.
Where the Rules Break
- Refinance and cash-out. Projection-based qualification is mainly a purchase path. Refinances usually expect about 12 months of actual hosting history, with refinance leverage up to 70% and short-term-rental cash-out also up to 70%, versus 75% on a purchase. A new owner who wants to pull equity early may be steered to the long-term-rent fallback, which Lendmire’s piece Can You Cash Out on Projected Airbnb Income With a DSCR Loan? explains.
- Thin comps. If the projection fails or the comp data is weak, the long-term market rent on the 1007 is the usual fallback. It generally produces lower qualifying income, and so a smaller loan.
- The 1007 is not an Airbnb form. Fannie Mae’s Appraiser Update addresses short-term rentals and Form 1007 specifically, describing the form as documenting estimated monthly market rent. Do not expect it to capture nightly-rate income.
- Occupancy rules. These are investment loans for non-owner-occupied property. Borrowers typically sign an occupancy affidavit, so a vacation home you plan to use heavily belongs on a different loan.
- Local 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.
- Ineligible property types. Manufactured homes, log homes, and barndominiums are not offered in these programs, however good the projection looks.
What Does This Mean for Your Decision?
A projection-based approval lets a first-time host buy without a track record. The trade is a discounted income figure and potentially tighter leverage. The income method you choose can change the loan size, so it is worth running both the projection and the 1007 rent before you commit.
Schedule risk is real too. Construction delays push back the CO, and the DSCR close sits behind it. Build your timeline with that dependency in mind.
Market context is secondary. AirDNA’s own blog reported a national snapshot of 57.2% occupancy and a $258.91 ADR across 1.73 million U.S. listings in one recent month, but a national average says little about a specific house.
After the first year of hosting, the path opens to a refinance on actual history, where real statements replace the forecast.
One practitioner observation: across comparable new-build files, the strongest ones arrive with the report run, the comps screened, and the conservative case already calculated, so surprises at review are rare. Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Frequently Asked Questions
Can a brand-new Airbnb qualify with no rental history?
Yes, on a purchase, when the lender accepts a third-party projection or an appraiser’s analysis in place of booking history. The home generally must be complete, with a CO, before the DSCR loan closes. Qualification remains subject to lender guidelines, credit approval, and property review.
What if the projection comes in low?
Reconcile it first. Check whether the comps match your bedroom count and amenities. If the number still falls short, options include a lower LTV, the long-term rent fallback, or a select-lender path that allows coverage below 1.00 with leverage and terms adjusted. Each is reviewed case by case.
Does the builder’s rental estimate count?
No. A builder’s marketing figure or a listing’s advertised nightly rate is not the coverage figure. The lender wants a report or appraisal tied to your specific property.
Can a DSCR loan fund the construction itself?
Generally no. It is take-out financing after completion. A construction loan or cash carries the build, and the DSCR loan replaces it once the home has a CO and meets property eligibility.
Does clearing 1.00 mean the property makes money?
No. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital costs sit outside it, and short-term rentals carry more of those costs than long-term leases.
