The Quick Read: A lender qualifies a building like this on the property’s own income, so the real work is proving which income figure counts: nightly bookings, a market projection, or long-term rent, all tested against one full monthly payment on the whole building. Eligibility depends on lender guidelines, credit approval, and property review, and none of this is a commitment to lend.
- Short-term-rental purchase leverage tops out at 75% LTV on an investment property, and a 640+ credit score is the usual expectation.
- Select programs start at 1.00 coverage, and stronger ratios open better pricing and leverage.
- The appraisal sets value and long-term market rent. The lender decides how nightly income counts.
- Clearing the coverage test does not mean the building cash flows.
- Every unit must be legal for nightly stays, and the building must be a legal four-unit property. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Why a Fourplex Is a Residential Loan, Not a Commercial One
A building with two to four units is generally financed as a residential investment property. That keeps it inside the residential investor programs rather than a commercial loan. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.

Short-term rental figures are estimates only and vary significantly by season, property type, management approach, and local short-term-rental rules — confirm local regulations before relying on them. 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.
Most investors reach for a DSCR loan on this kind of building for a practical reason. A conventional mortgage looks at your traditional personal-income documentation, your debt-to-income ratio, and often your plan to live in the property. Four full-time Airbnbs fit none of that. You are not living there, and your personal income is not the point.
A DSCR loan flips the question. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR stands for debt service coverage ratio, which is a measure of whether the property’s income covers its own debt.
You cannot live in one unit under this structure. An owner-occupied purchase is a different product with different occupancy rules. It is the route to look at if you want to house-hack, but it is not the route for four units on the nightly calendar.
How a DSCR Lender Sees One Building With Four Airbnbs
The lender runs one test, not four. A fourplex has one loan, one tax bill, and one insurance policy. The lender adds up the qualifying income from all four units and divides it by a single payment.
That payment is called PITIA: principal, interest, taxes, insurance, and association dues. Many DSCR programs divide gross rent used for lender review by PITIA and stop there.
Investor-education sources define the ratio differently. Stessa describes DSCR as net operating income divided by debt service. That version subtracts operating costs first, and the simplified PITIA version does not. The two are different calculations, so do not blend them when you read a lender’s sheet.
One more point helps fourplex buyers. Four units share one set of fixed carrying costs. That is why multi-unit buildings often show stronger coverage than a single-family home at a similar price.
AirDNA’s educational blog notes that lenders scrutinize coverage more closely on short-term rentals because the income varies. That is the honest tension in this deal. Nightly income can be high, but it is also less predictable than a lease.
For the background on how these loans work generally, see Lendmire’s complete DSCR loans guide.
Which Income Figure Counts?
This is where the file is won or lost. Four routes exist, and each program accepts a different mix of them.
| Income path | What the lender reviews | When it fits |
|---|---|---|
| Hosting history | About 12 months of platform statements tied to bank deposits | Building already operates as STRs |
| Market projection | Third-party report plus comparable listings | Purchase with no history, where accepted |
| Appraiser’s STR analysis | Narrative analysis added to the appraisal | Program accepts it for the building |
| Long-term rent | The unit-by-unit rent schedule | Fallback, or a floor test |
Whether a program accepts each path is a program-level decision. On files where a building is already operating, expect about 12 months of hosting history. For a purchase with no history, the lender decides whether a projection or an appraiser’s analysis can stand in. Across the wholesale network, the answer changes from lender to lender.
Most lenders also count nightly income at a discount to gross. The discount stands in for the costs that PITIA leaves out. The exact factor is specific to each program, so ask for it before you price the deal.
What the Appraiser Does and Does Not Do
For a two-to-four-unit building, the appraisal is typically Form 1025, the small residential income property report. It sets the building’s value, which drives how much you can borrow. It also carries a unit-by-unit rent schedule, and that schedule is long-term rent.
The single-unit rent form, Form 1007, was never built for nightly pricing. HousingWire reports that the form was not designed to support short-term rental income. It adds that appraisers asked to repurpose it are encouraged to decline. It also warns that forcing nightly income onto the form can produce artificially low coverage ratios.
Class Valuation lists what a rent form cannot capture. That list covers dynamic nightly pricing, seasonal and event demand, volatile occupancy, host reviews, cleaning and turnover costs, and variable management fees. It also notes that non-QM lending is not bound by agency eligibility rules, so each lender decides how to handle STR income. Non-QM means a loan outside the standard agency box, and DSCR loans fall in that category.
The takeaway is simple. Do not expect the appraiser to value your Airbnb income. Expect the appraiser to set value and long-term rent, and expect the lender to decide the rest.
A Four-Unit Worked Example
Run the numbers on a building with four equal units. These are modeled assumptions, not market data.
Assume the lender’s qualifying income on the STR path comes out near 1.30x PITIA. Assume the appraisal’s long-term rent schedule, run on its own, comes out near 1.05x. Here is how both paths hold up under stress.
| Scenario | STR path | Long-term rent path |
|---|---|---|
| Base case | 1.30x | 1.05x |
| One unit sits dark | about 0.98x | about 0.79x |
| All four units 20% emptier | about 1.04x | about 0.84x |
The STR path clears 1.00 in the base case and in the occupancy-drop case. It slips just under when one whole unit goes dark. That is the pattern to watch in a building this small, because each unit is a quarter of the income.
A result under 1.00 is not necessarily the end of the file. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. By comparison, 1.00 is where many select programs start. Either way, qualification stays subject to lender guidelines, credit approval, and property review.
Test all three paths before you choose a structure. The same building can show very different coverage depending on whether it runs on long-term rent, a projection, or booking history.
Coverage Is Not Cash Flow
Clearing 1.00 does not mean the building puts money in your pocket. The ratio compares income to PITIA only. It leaves out cleaning, platform fees, utilities, furnishing, repairs, management, and vacancy.
Those costs are heavier on four Airbnbs than on four leases. Every turnover needs a cleaning, and every unit needs furniture, linens, and supplies. A building that covers its payment at 1.10x can still lose money after those costs.
So run two tests. The lender’s test asks whether the income covers the payment. Your own test asks what is left after the real operating costs.
Skeptical investors do one more thing. They check the projection against real competing listings in the same area before trusting it.
The Program Numbers to Expect
These are typical ranges across select lenders in Lendmire’s wholesale network. They are not promises, and every file is underwritten individually.
- Purchase leverage: On a short-term-rental purchase of an investment property, leverage tops out at 75% LTV. LTV means loan-to-value, the loan as a share of the property’s value. Standard long-term rentals reach 75%–80% LTV on a purchase.
- Refinance and cash-out: A short-term-rental refinance runs around 70% LTV. A short-term-rental cash-out refinance tops out at 70% LTV, while a standard rental cash-out reaches 75%.
- Credit: Expect a 640+ score on short-term-rental files. Standard rental programs run a 620 floor in parts of the network, with most wanting around 660 and 700+ unlocking the strongest tiers.
- Coverage: On a purchase, coverage starts at 1.00 in select programs. On a refinance, select programs also start at 1.00.
- Loan size: Standard programs run up to $3,000,000. A fourplex purchase usually sits well inside that range.
- Reserves: About 6 months of PITIA is common. Loans above $1,500,000 typically step up to about 9 months. Reserves vary by lender, leverage, loan size, and transaction type.
A bigger down payment lowers the payment and can lift coverage. It does not erase credit floors, reserve rules, or property eligibility. The strongest files clear both tests, enough equity and enough rental coverage.
Select lenders in the network also offer 40-year terms and interest-only periods, and ARM structures exist for investors who want them. The 30-year fixed remains the spine of most programs.
Where the General Rules Break
One Airbnb unit and three leases. A mixed building may be underwritten with part STR income and part lease or market rent. Whether a program allows that mix is a program-level call. If you want a smaller version of this strategy, Lendmire’s piece How to Finance a Duplex You Will Run as Two Airbnbs covers the two-unit case.
All four units on the nightly calendar. Some lenders treat this as its own scenario with extra overlays. It behaves more like a small lodging operation than a single-family STR. Shared walls also mean guests can hear neighbors, which affects reviews and occupancy.
A fourplex that is not legally a fourplex. Lenders have declined buildings that turned out never to be zoned for four units. Confirm the legal unit count and single-parcel status before you spend money on an appraisal.
Markets with no long-term rental base. In seasonal areas, the long-term fallback rent may be weak or unavailable. The STR income path then matters much more, and the projection gets more scrutiny.
A stretched appraisal. An appraiser who declines to push nightly income onto a rent form is doing the right thing. A figure forced onto that form can sink a deal even when bookings are strong.
Pooled structures. Putting several rentals under one note is an alternative to separate loans. Whether coverage is tested per property or across the pool depends on the program.
Ineligible property types. Manufactured homes, log homes, and barndominiums are not offered through the network’s DSCR programs.
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.
Legality, Insurance, and Entity Setup
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. In a fourplex, legality has two layers. The building must be a legal four-unit use, and each unit must be legal for nightly stays.
Lenders also want an insurance quote written for short-term rental use, not a standard landlord policy. Get that quote early, because it feeds PITIA and the coverage number.
If you hold the building in an LLC, subject to lender program eligibility, make sure the entity name matches the deposit account that receives booking income. A mismatch slows down the review.
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.
From Contract to Funding, Step by Step
1. Confirm the building is a legal four-unit property and that every unit may host nightly stays.
2. Choose the income path: hosting history, a market projection, or long-term rent as a floor.
3. Run the coverage math on all three paths and decide whether the deal clears the bar you need.
4. Share the file with a broker who places loans across many lenders. Programs differ on income paths and discounts.
5. Order the appraisal and confirm the lender’s treatment of nightly income before the report is finalized.
6. Gather the documents: projection report, platform statements if operating, comparable listings, any STR permit, HOA documents, the STR-use insurance quote, and entity papers.
7. Keep your reserves documented, since they are part of the review.
After the First Year: Refinance and Scale
Once the building has about 12 months of hosting history, the financing picture changes. You now hold real booking data instead of a projection. That data can support a refinance, and a short-term-rental refinance runs around 70% LTV, as noted above. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Cash-out has its own rules. Lendmire’s piece Does a Fourplex Get the Same DSCR Cash-Out Terms as a House? covers how seasoning and leverage work on multi-unit buildings. About 6 months of seasoning is the common expectation across the network.
Because DSCR files do not rest on your personal debt-to-income ratio, many investors repeat the process on the next building. Each building is still reviewed on its own income, credit profile, and reserves.
Key Terms Defined
DSCR: The ratio of a property’s qualifying income to its monthly debt payment. A result above 1.00 means income exceeds the payment.
PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly obligation the lender tests against.
LTV: Loan-to-value, the loan amount as a percentage of the property’s appraised value.
Hosting history: The record of past bookings and revenue for a short-term rental, usually shown by platform statements and bank deposits.
Market projection: A third-party estimate of what a short-term rental should earn, used when no history exists.
Seasoning: The waiting period a lender wants between owning a property and refinancing it.
Frequently Asked Questions
Can I live in one of the four units?
Not under a DSCR loan. These loans are for non-owner-occupied investment properties. If you want to occupy a unit, you need an owner-occupied product with different rules, and those rules generally do not suit four full-time nightly rentals.
Do I need hosting history to buy?
It depends on the program. A building that already operates typically needs about 12 months of platform statements tied to bank deposits. For a purchase with no history, some programs accept a market projection or an appraiser’s analysis, and the lender decides which figure counts.
Will the appraiser count my Airbnb income?
Generally no. The appraisal sets value and a long-term rent schedule, and the lender decides separately how nightly income is treated. Business-driven factors like pricing, occupancy, and cleaning costs fall outside the rent form.
What happens if one unit sits empty?
Coverage drops by roughly the share of income that unit produced. In a four-unit building, one dark unit removes about a quarter of income, so the number can fall near or below 1.00. Select lenders in the network will review coverage below 1.00 with leverage and terms adjusted.
Is a fourplex commercial or residential?
A two-to-four-unit building is generally financed as a residential investment property. That puts it within residential investor programs rather than a commercial loan, subject to lender guidelines.
