The Quick Read: A 10-unit building closes on a DSCR loan when its net operating income covers the annual debt service, a commercial appraisal supports the value, and the building is stabilized and mostly leased. The loan also has to sit with a select lender in the wholesale network that offers the five-to-ten unit tier. The file runs differently from a duplex or fourplex, with heavier property documents and lighter personal-income paperwork.
- The test changes at five units. Smaller buildings compare rent to the full payment (principal, interest, taxes, insurance, and any HOA dues). Larger ones are usually measured on net operating income against debt service.
- The appraisal changes too. Expect a commercial report built on income, from an appraiser with commercial credentials.
- Lender choice narrows. Ten units is the top edge of the tier, and many lenders do not offer it.
- Stabilization matters. Heavy vacancy or renovation usually points to a bridge loan first.
- Equity and coverage both count. A bigger down payment helps the ratio but never erases leverage caps, credit floors, or reserve rules.
Why Does a 10-Unit Building Close Differently Than a Fourplex?
A 10-unit building is underwritten as a small commercial asset. The lender looks at what the building earns after operating costs, not at one rent figure against one payment. The appraisal, the paperwork, and the pool of lenders all change at the same time.

The five-unit line itself is a convention more than a law of nature. A building with five or more units is generally classed as multifamily and grouped with commercial real estate loans, according to a Real Estate Financial Planner explainer on debt service coverage. Here is how the two files compare:
| Factor | 1–4 units | 10 units |
|---|---|---|
| Income test | Rent vs. full payment | NOI vs. debt service |
| Appraisal | Residential report | Commercial, income-driven |
| Appraiser | Residential license | Certified General (most states) |
| Key documents | Lease or rent schedule | Rent roll, leases, T-12 |
| Lender pool | Wide | Narrow, select lenders |
Appraiser Point confirms that five or more units require commercial appraisal forms. It adds that a Certified General appraiser must do the work in most states.
The structure still feels closer to a residential investor loan than to a traditional commercial multifamily loan. Commercial loans often come with a balloon payment. DSCR programs in the network are built around the 30-year fixed spine, with extended terms and interest-only periods available through select lenders.
Are You in the Right Lane Before You Start?
Check three things before you order anything: whether the building is stabilized, whether the unit count is legal, and whether you need a lender that offers this tier. A mostly vacant or half-renovated building usually does not fit a DSCR file, because the lender underwrites income that exists today.
Here are the three common lanes:
- Stabilized and leased: This is the DSCR lane. The rent roll is full, the leases are current, and there are operating statements to verify.
- Needs work or lease-up: A short-term bridge or hard-money loan comes first. Then you refinance into a DSCR loan once the building performs. Lendmire’s piece How to Move From Flips to a 5-to-10-Unit Building With Hard Money walks through that handoff.
- Over ten units: Programs thin out, and a bank or agency path may fit better.
Mixed-use buildings need extra care. Appraisals Unlimited says commercial and residential income streams should be analyzed separately, with different vacancy and cap-rate treatment. A building with a ground-floor shop and nine apartments is a different file than ten apartments.
Separate small buildings also do not combine into one loan. Three fourplexes on different parcels stay three loans, unless the units sit on the same or adjoining tax parcel.
How Does Underwriting Actually Treat the Income?
Lenders on a 10-unit file start with net operating income, called NOI. That is rental income plus other building income, minus the direct costs of running the property. They divide NOI by the year’s debt service. A result above 1.00 means the building’s income exceeds its loan payments.
Mortgage principal and interest stay out of NOI, as the Real Estate Financial Planner explainer notes. They sit in the debt service line on the other side of the division.
Here is how the lender builds the number:
1. Start with the rent roll, which lists every unit, its tenant, its rent, and its lease dates.
2. Add other income, such as laundry or parking.
3. Subtract a vacancy allowance, even if the building is full today.
4. Subtract operating costs: taxes, insurance, repairs, utilities the owner pays, and a management line.
5. Divide the result by annual debt service.
The management line surprises owner-operators. Many lenders include a management cost even when you plan to self-manage, so your own labor does not count as free.
Where does 1.00 fit? Across the network, 1.00 is where many select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Commercial lenders often want more cushion, and there is no single universal minimum.
One caution applies even to a strong ratio. DSCR measures income against the loan payment only. Clearing 1.00 does not mean positive cash flow, because capital repairs, turnover costs, and your own reserves sit outside the calculation.
What Leverage, Credit, and Reserves Should You Expect?
On most files, purchase leverage on an investment property runs 75%–80% LTV, which is 20%–25% down. LTV is the loan amount divided by the property’s appraised value. Ten-unit files can sit toward the lower end of that range, and some lenders set tighter caps at five units and above, so ask early.
A cash-out refinance of an investment property tops out around 75% LTV across most of the network. About six months of seasoning, meaning ownership time before the refinance, is the common expectation. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Credit works in tiers. A 620 floor exists in parts of the network, most programs want around 660, and 700 or higher unlocks the strongest leverage tiers. All of this is subject to lender guidelines.
Loan size matters on this property type. Standard programs run up to about $3,000,000, and above $2,500,000 the network generally holds to 30-year fixed structures. Larger balances push you into the territory covered in Lendmire’s guide to super jumbo DSCR requirements for a five-to-ten unit building.
Reserves are liquid cash left after closing. They vary by lender, leverage, loan size, and transaction type. About six months of PITIA is common, and loans above $1,500,000 typically step up to about nine months. A 10-unit purchase often lands above that line, so plan on the higher figure.
More down payment lowers the payment and can lift the ratio. It still cannot lift a leverage cap or fix a credit floor. The strongest files have enough equity and enough rental coverage together.
The Closing Sequence, Step by Step
Each step below says what happens, what you provide, and what can stall it. Many run in parallel with your purchase contract’s due-diligence window, so line them up early.
1. Classify the building. Confirm the unit count, the legal use, and that all units sit on one parcel. A unit count that does not match records can stall the file later.
2. Get a program match. Your broker screens the deal against lenders that offer the tier. You supply the contract or property details, the rent roll, and an entity summary. The stall point is a lender that does not offer ten units.
3. Collect the document package. The lists are below. The stall point is a missing lease or an operating statement that does not match the rent roll.
4. Order the commercial appraisal. Appraisals Unlimited says at five units and above the income approach becomes the primary driver of value. Contract rents are compared against market rents for the submarket. The stall point is the appraiser, since Certified General status narrows the field and commercial reports take longer to deliver than residential ones.
5. Size the loan. Loan size runs off the appraised value, not the contract price. Larger deals often get a second check called debt yield, which is year-one NOI divided by the loan amount.
6. Underwrite the borrower. The lender reviews credit, liquidity, and ownership history, plus title and insurance items. Entity documents and a real-estate-owned schedule are the usual requests. The stall point is slow answers to conditions.
7. Clear conditions, then sign and fund. Signing for an entity takes the right authorized signer. Funds move through the title company.
What Documents Does a 10-Unit File Need?
Personal-income paperwork is light, because the loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Property paperwork is heavy. Lenders typically ask for these:
Property
- Current rent roll and a lease for every unit
- Trailing 12-month operating statement (a T-12)
- Insurance quote or binder for the building
- Purchase contract, or deed and prior financing for a refinance
Borrower and entity
- Government ID and credit authorization
- Evidence of reserves
- Real-estate-owned schedule
- Entity documents, such as articles, operating agreement, and good standing, if you close in an LLC (subject to lender program eligibility)
Third-party
- Commercial appraisal
- Title work
- Any property condition or environmental screening the lender requires
Tenant verification can also come up, such as lease confirmation or estoppels. An estoppel is a tenant’s signed statement of their rent, deposit, and lease terms. Whether they apply depends on the lender.
A Worked Example: How a Haircut Changes the Answer
Here is a hypothetical 10-unit building. All inputs are modeled assumptions, not market data.
Suppose the owner’s gross-rent math suggests coverage around 1.45x. That number assumes every unit rents all year and costs are light.
1. Gross rent only: Coverage is roughly 1.45x.
2. After a vacancy allowance: The lender haircuts income, and coverage slips to about 1.35x.
3. After operating costs and management: Coverage settles near 1.12x.
The building still clears 1.00, but the cushion is thin. Now suppose the actual T-12 shows heavier repair and utility costs than the owner assumed. Coverage could fall under 1.00.
That is the NOI shock, and it is the most common surprise on larger files. Gross rent can look fine while NOI falls below the payment. These are the options a lender would review:
- Lower the loan amount. More equity down brings debt service down and lifts the ratio, within the leverage caps.
- Renegotiate the price. A lower price supports a smaller loan on the same income.
- Use a sub-1.00 path. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted.
- Raise NOI before closing. Cutting expenses or lifting rents raises both value and coverage.
Qualification stays subject to lender guidelines, credit approval, and property review. The goal is to learn your coverage before the appraisal is ordered, not after.
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.
When Something Goes Wrong
Most failures on 10-unit files are predictable. Here is the pattern:
| Problem | Typical fix |
|---|---|
| Appraisal comes in low | Add equity, renegotiate, or resize |
| NOI cut by lender | Lower loan amount or raise NOI |
| Vacancy at underwriting | Wait, bridge first, or restructure |
| Unit count or use mismatch | Resolve with title and records |
| Entity authority gap | Fix documents before signing |
| Insurance delay | Quote early, bind before funding |
On the appraisal, a low value shrinks the loan, because sizing runs off appraised value. On a purchase, that can mean a price conversation with the seller. Negotiate before your due-diligence deadline passes.
On the NOI side, tax treatment varies by situation, so consult a qualified professional about how any expense changes affect your return.
Where Does the Money Go at Closing?
Costs fall into categories, and a 10-unit file runs heavier than a one-to-four unit file. Here they are in the order you tend to pay them:
- Appraisal: The commercial report costs more than a residential one.
- Third-party reports: Environmental or property condition reports are added when the lender requires them.
- Legal and entity costs: Document review and entity work add up on larger deals.
- Title and recording: These cover the policy, the search, and recording fees.
- Lender and broker compensation: Both are disclosed in your loan paperwork, so compare total terms across lenders.
- Insurance and escrows: Prepaid premiums and any required reserve accounts come at closing.
Business-purpose loans are not covered by the consumer disclosure timing rules, so the lender’s own documents govern.
Closing Day and the First Month After
Signing for an entity requires the authorized signer, and the lender wants the signing authority to match the entity documents. Funds move by wire through the title company, and the deed and mortgage are recorded afterward.
After closing, you have tenant-side tasks. Notify tenants of the new payment channel, confirm how deposits transfer, and prorate rents with the seller. Set up the reserve account if the lender requires one. Then calendar your insurance renewal and your lease expirations, since those drive next year’s NOI.
DSCR Loan or Bank Loan on a 10-Unit Building?
A DSCR loan is usually the easier file to qualify for. A bank loan may fit better when you want the bank relationship or you are above ten units. Here is how they compare:
| Factor | DSCR loan | Bank commercial loan |
|---|---|---|
| Personal income docs | Light | Heavier |
| Structure | 30-year fixed spine | Often shorter, with balloon |
| Credit and vacancy flexibility | More lenient | Stricter |
| Lender pool for 10 units | Narrow | Broader |

Common Mistakes That Derail 10-Unit Files
- Assuming the calculation is rent over payment. On five or more units it is usually NOI over debt service.
- Expecting a residential appraisal form to work. The Fannie Mae Selling Guide limits Form 1025 to two- to four-unit properties and Form 1007 to a one-unit rent schedule. Neither covers ten units, and DSCR loans are not agency products anyway.
- Treating light personal paperwork as light scrutiny. The property gets the full review instead.
- Counting on a pro forma. Lenders weigh actual operating history over projected rents.
Key Terms Defined
NOI (net operating income): Rental and other building income minus direct operating costs, before loan payments.
Debt service: The year’s loan payments, covering interest and principal.
DSCR (debt service coverage ratio): Income divided by the loan payment, which shows how well the property covers its debt.
PITIA: Principal, interest, taxes, insurance, and any association dues.
LTV (loan-to-value): The loan amount as a percentage of the appraised value.
Rent roll: A unit-by-unit list of tenants, rents, and lease dates.
T-12: A trailing 12-month operating statement of income and expenses.
Estoppel: A tenant’s signed statement confirming rent, deposit, and lease terms.
Debt yield: Year-one NOI divided by the loan amount, a second safety check on larger loans.
Reserves: Liquid cash kept after closing to cover the loan payments.
Frequently Asked Questions
Can I use a DSCR loan on a 10-unit apartment building?
Sometimes, through select lenders that offer the five-to-ten unit tier. Ten units sits at the top edge of that tier, so the lender pool is narrow. The file is underwritten on the building’s NOI, subject to lender guidelines and credit approval.
Why is my lender’s DSCR lower than the number I calculated?
Lenders use NOI, not gross rent. They apply a vacancy allowance, a full expense load, and often a management cost. That brings coverage below the gross-rent figure. Run your own numbers the lender’s way before you go under contract.
Can I close in an LLC?
Often, yes, subject to lender program eligibility. Expect to provide entity documents and have an authorized signer sign. Many lenders also want a personal guarantor on the loan.
What if the building is not fully leased?
Heavy vacancy is a coverage problem, not a lease-up-after-closing story. A bridge loan followed by a DSCR refinance is a common path. Qualification for any structure stays subject to lender guidelines.
What delays a 10-unit closing most?
The commercial appraisal and document gaps cause most delays. An operating statement that does not match the rent roll is a frequent culprit. Collect leases and statements before you apply, and quote insurance early.
