Yes, some investor programs can finance a new vacation rental using an accepted projection instead of an operating history. The useful question is which evidence the program will accept for this property and this borrower.
A furnished home, an Airbnb estimate and a large down payment do not by themselves answer that question. I would settle the income method before using a projected loan amount to set the purchase budget.
Start with what is actually missing
A newly built home has no operating record. A former primary residence may have a market but no guest history. A newly converted vacation rental may have a few promising weeks. Those are different evidence problems.
A lender can permit one scenario and restrict another. A purchase using projected revenue is also different from refinancing a property that has failed to produce the revenue originally expected.
Write down the transaction type, current use, planned use, prior operating period and borrower experience. That small fact sheet prevents the wrong program being evaluated from the start.
There is a real projection path, with real conditions
As a specific published example, AD Mortgage's September 24 2026 guideline permits estimated short term rental income on a purchase when actual income is unavailable. The stated path uses 75% of an eligible AirDNA Rentalizer estimate with at least 60% occupancy, or 75% of eligible Form 1007 STR market rent using STR comparables.
Those are that investor's documented conditions, not an industry standard. Other matrix restrictions still apply. In particular, do not assume a first time homebuyer, a first time investor and an experienced rental owner receive identical treatment.
The report must describe the property being financed. An estimate for a larger nearby house with a pool does not establish the income of a smaller house without one. Nor does an estimator's output establish zoning permission.
I would want the actual calculation in the preapproval notes: source, revenue period, adjustment, qualifying payment and resulting coverage. An approval described only as Airbnb income accepted leaves too much undecided.
Work backward from accepted income
Hypothetical purchase illustration: an eligible report estimates $84,000 in annual STR revenue. Applying the example's stated 75% treatment produces $63,000 annually, or $5,250 monthly. If the program's applicable payment is $4,200, the ratio is 1.25.
At a $4,600 payment, the same accepted rent produces about 1.14. At a $4,200 payment with accepted monthly rent reduced to $4,500, the ratio is about 1.07. None of those numbers establishes universal eligibility. They show why final taxes, insurance, association charges and accepted revenue belong in the analysis early.
A raw $84,000 divided by 12 gives $7,000 monthly. Using that unadjusted amount would show 1.67 against $4,200 and materially overstate this particular method.
The next question is whether a lower loan amount, different financing path or better supported income resolves the actual constraint. Raising the forecast just to reach a desired ratio is not a remedy.
Check the business before relying on the projection
I would compare the report's assumed home with what you will actually deliver: bedroom count, legal guest capacity, amenities, condition, furnishing and likely launch date. A plan to add features later does not establish that they exist at closing.
Review the comparable set as well. Professionally photographed, established homes with many reviews may achieve a different opening performance from a new listing. That difference belongs in your operating budget even if the lender accepts the report.
If the property does not legally permit the intended rental use, the projection is solving the wrong problem. Verify the governing city or county and association documents. A postal address or neighboring Airbnb listing is weak evidence of permission.
Your bank balance has to survive opening day
Consider a separate hypothetical $520,000 purchase. At 25% down, the buyer uses $130,000 and borrows $390,000. Assume $15,000 in closing expenses, $35,000 in furnishing and $5,000 in other launch spending.
Total planned spending is $185,000. A buyer starting with $200,000 has $15,000 left. If the selected file separately requires six months of eligible reserves against a $4,200 payment, the target is $25,200. The cash plan is $10,200 short if this is the only eligible asset account.
That six month requirement is an assumption for this example, not a promise about a named program. Furnishing commitments and other cash uses still need to be disclosed and reflected in the actual asset analysis. The lender's eligible reserve calculation and your operational cash cushion may differ.
Even a loan with lower required reserves would leave a separate business question: can $15,000 cover slow bookings, repairs and startup friction? I would not spend the operating cushion simply because underwriting did not require it to remain.
Do not solve the file with a pretend lease
An investor may consider a genuine long term rental plan if that use and financing fit. That is different from creating a paper lease while intending immediate nightly rentals.
Disclose the actual occupancy and business plan. If a program uses long term market rent to qualify a permitted STR, get that treatment established under the program. Do not assume choosing a different report authorizes a different use.
The same care applies to second home financing. Personal use, management control and whether income is needed for qualification affect that analysis. The occupancy guide addresses those distinctions.
What I would resolve before removing financing protection
I want a supported property classification, permitted rental use, the accepted income report, the selected program's borrower restrictions, the full qualifying payment and a funded launch plan. Each can change the purchase amount you can responsibly commit to.
A projection can be legitimate evidence for an eligible loan. It remains a projection for the business. Carry a conservative operating case alongside the lender's calculation so that both the closing and the first year have a workable funding plan.
