The Quick Read: It depends on the program. A 10-unit building is classified as commercial multifamily, so it does not fit the standard 1–4 unit DSCR product. Some select lenders in the wholesale network run a separate 5–10 unit tier with its own underwriting. Whether your building qualifies turns on the unit cap, the income test, and the property’s condition.
- Four units or fewer is residential. Five or more is commercial multifamily.
- Ten units is usually the top of any stretched DSCR tier. Above that, commercial financing is the norm.
- Coverage at five-plus units is often measured on net operating income, not rent against the payment.
- The appraisal moves from a rent schedule form to a commercial income-approach report.
- Stabilized, leased buildings fit best. Heavy rehab or high vacancy points to other financing.
Why Does Ten Units Sit at the Edge?
The line falls between four and five units, and ten is where most stretched DSCR programs run out of room. Four units and under is a residential loan. At five, the same lender is writing a commercial loan, even when the building looks like a fourplex with extra doors.

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.
Agencies draw the same line. The Fannie Mae Selling Guide assigns the Form 1025 small residential income appraisal to two- to four-unit properties. Those are agency products, not DSCR. They only show where the market puts the boundary.
Across the wholesale network, unit caps are program-specific. Some programs stop at four units. A few select lenders reach into the 5–10 range under separate guidelines. Nobody should assume a 10-unit fits until the program’s cap is confirmed in writing. For the broader picture, see the complete DSCR loans guide.
The reason caps vary is structural. Loans on one to four units are built to be pooled into residential securitizations. A five-plus unit loan generally does not fit that mold, so each lender decides how far to stretch.
How Does the Coverage Math Change at Five or More Units?
On one to four units, the ratio is rent divided by the full housing payment: principal, interest, taxes, insurance and any association dues. Repairs and management are not deducted first.
At five or more units, many programs measure coverage as net operating income divided by debt service. NOI is income after vacancy, minus operating expenses. It leaves out debt service, income taxes, depreciation and capital expenditures. Some 5–10 programs use a hybrid, such as NOI over PITIA. Ask which formula the program uses. The two cannot be swapped.
Here is the practical effect. Picture an investor who cleared a fourplex comfortably by comparing rent to the full payment. Move that same investor to a ten-unit and run the same rents through an NOI test. Vacancy, management, repairs and utilities now come out before the ratio is calculated. Coverage lands lower, sometimes well lower. A building that looked like 1.3x on gross rent can drop toward 1.0x or below once expenses are counted.
That is a modeled illustration, not a market figure. The point holds either way: the same building can clear one test and miss the other.
One caution on terms. A coverage ratio at or above 1.00 is not positive cash flow. DSCR compares income to the debt payment only. Repairs, vacancy, management and capex still sit outside it on a one-to-four unit file and are partly inside it on a commercial one.
On the network side, 1.00 is where select programs start. Stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
How Does the Appraisal Change?
The appraisal gets heavier. On one to four units, appraisers use the 1025 income property report, which includes a rent schedule and operating income, with comparable sales. The 1007 is the single-family rent schedule form.
At five or more units, the report is a commercial, income-approach narrative built on NOI and cap rate. AppraiserPoint’s multifamily appraisal guide notes these reports follow commercial forms and often need a Certified General appraiser. They run longer and cost more than a standard residential report.
For file planning, that means two things. Budget more for the appraisal. And expect the value to rest on the building’s operating numbers, not just nearby sales. A weak expense history can pull the value down even when rents look strong.
What Does the Lender Review on a 10-Unit File?
Documentation is where preventable gaps show up. On a commercial-style file, plan to supply:
- A full rent roll, unit by unit
- Every current lease
- Trailing operating statements showing expenses
- Occupancy history
- Entity documents, subject to lender program eligibility
- Reserves documentation
- Property condition information
- Borrower experience in the property type
Experience matters more here. Some 5–10 programs ask for prior multifamily ownership. A first-time investor stepping from a fourplex to a ten-unit should ask about that requirement before ordering the appraisal.
The network’s usual guardrails still apply on the credit side. A 620 floor exists in parts of the network, most programs want around 660, and 700 or higher opens the strongest leverage tiers. Reserves vary by lender, leverage, loan size and transaction type. They commonly run around six months of PITIA, and loans above $1,500,000 typically step up to about nine months. Purchase leverage on most files lands at 75%–80% LTV on an investment property purchase. Cash-out refinances top out around 75% LTV. A 10-unit under a specialty tier may sit at the lower end of those ranges, since these programs often carry tighter leverage. All of it is subject to lender guidelines, and every file is underwritten individually.
The network figures above are the ones that govern a Lendmire-arranged file. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
DSCR Program or Commercial Loan? A Decision Path
Run the building through five questions, in order.
1. Does a program cover ten units at all? If the lender’s cap is eight, stop. This is the first gate.
2. Is the building stabilized? Leased, with a clean rent roll, fits a DSCR-style tier. Heavy vacancy or a rehab plan points to bridge or other commercial financing.
3. Does the NOI hold up? Run coverage on the expense-adjusted number, not gross rent.
4. What is the hold period? Traditional commercial loans often carry balloons that force a refinance on a schedule you do not control. Confirm whether the 5–10 program amortizes fully.
5. Is there a commercial component? Mixed-use treatment depends on how the building is used. Ask before making an offer.
| Lane | Best fit | Watch for |
|---|---|---|
| Specialty 5–10 DSCR tier | Stabilized, leased building | Unit cap, tighter leverage |
| Bank or portfolio loan | Borrower with local bank ties | Heavier documents, balloons |
| Agency small-balance | Larger or institutional-style deals | Own minimums, not DSCR |
| Bridge first | Vacancy or heavy rehab | Short runway, refinance risk |
Local banks are the usual source for five to twelve units, which is hard for out-of-state investors. A DSCR-style 5–10 program is one way around that, when the building and borrower fit it.
Term structure is worth a question too. The spine of the network is the 30-year fixed. Extended terms and interest-only periods exist through select lenders, and ARM structures are available for investors who want them. Above $2,500,000, the network generally holds to 30-year fixed.
Where DSCR Usually Doesn’t Fit
Four situations push a 10-unit away from a DSCR tier:
- Heavy rehab or high vacancy. The income test needs stabilized rents to work.
- Owner-occupied buildings. 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.
- Mixed-use with meaningful commercial space. Treatment varies by lender.
- Ineligible property types. Manufactured homes, log homes and barndominiums are not offered in the network’s DSCR programs.
Above ten units, expect commercial financing as the norm.
One broker-level observation: files at this size most often stall on the rent roll and the expense history, not on credit. An investor who shows up with twelve months of clean operating statements and leases that match the rent roll gives the lender fewer preventable gaps to review. That does not guarantee approval, but it shortens the list of questions.
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.
Questions to Ask Before You Order the Appraisal
Carry this list to the first conversation:
1. What is the maximum unit count in this program?
2. Is coverage measured on NOI or on rent against PITIA?
3. What leverage applies to a ten-unit purchase?
4. Is prior multifamily experience required?
5. Does the loan amortize fully or carry a balloon?
6. What happens if one unit is vacant at appraisal?
7. Which appraiser qualification is required?
A broker working across several lenders can screen these answers against multiple programs at once. Lendmire’s piece Should You Use a Broker or Go Direct for a DSCR Loan on a 5 to 10 Unit? covers that tradeoff.
Key Terms Defined
NOI (net operating income): Rental income after vacancy, minus operating expenses, before debt service.
DSCR (debt service coverage ratio): Income divided by the loan payment. The income measure differs by unit count.
Form 1025: The appraisal report for two- to four-unit income properties.
Balloon: A loan that amortizes over a long schedule but comes due in full earlier.
Stabilized: Leased at steady occupancy with a verifiable operating history.
Frequently Asked Questions
Do DSCR loans stop at four units?
Standard DSCR products do. Some select lenders extend a separate tier to roughly five to ten units, with their own guidelines. Whether a specific building qualifies depends on the program, the property and the borrower.
Is a 10-unit building residential or commercial?
Commercial. Residential classification ends at four units, regardless of how similar the building looks to a fourplex.
Does the DSCR formula change at ten units?
Often, yes. Many programs shift from rent over the full payment to NOI over debt service, and some use a hybrid. Confirm the formula before running numbers.
What if the building is partly commercial, or I live in one unit?
Mixed-use treatment varies by lender, so ask before making an offer. Owner-occupancy generally moves the file out of DSCR, which is built for non-owner-occupied investment property.
What if it has eleven units?
Expect commercial financing. Eleven sits past the range where DSCR-style tiers commonly operate.
