The Quick Read: To qualify, you need a stabilized building of five or more units whose actual net income covers the payment the lender tests, a credit score that fits the program, enough liquid reserves, and a rent roll that matches the signed leases. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The 40-year part changes which payment gets tested, and that one detail can decide a tight deal.
- Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better terms.
- Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
- Leverage: purchases typically land at 75%-80% LTV on an investment property. A cash-out refinance tops out around 75% LTV.
- Reserves: commonly about 6 months of PITIA, stepping up to about 9 months on loans above $1,500,000.
- Structure: 40-year terms and interest-only periods come through select lenders in the network, so ask which payment is used to qualify.
What Is a 5+ Unit, 40-Year DSCR Loan?
It is a business-purpose loan on a building with five or more units, sized mainly by what the building earns. The “40-year” label describes the payment structure. It usually means a 10-year interest-only window followed by 30 years of principal and interest. Sometimes it means a fully amortizing 40-year schedule.

DSCR stands for debt service coverage ratio. It measures whether the property’s income covers its debt payments. A ratio of 1.00 means income equals the payment. Anything above means a cushion.
The phrase “40-year” bundles three separate ideas, and mixing them up causes most of the confusion:
| Piece | What it means | Common setup |
|---|---|---|
| Note term | How long the loan contract runs | Up to 40 years |
| Interest-only window | Period paying interest, no principal | Often 10 years |
| Amortization tail | Years of principal and interest after | Often 30 years |
Some programs skip the interest-only window and amortize over the full 40 years. Others pair it with a shorter tail. Read the term sheet for all three pieces, not just the headline number.
Extended terms and interest-only periods are available through select lenders in the network. The spine of the lineup is still the 30-year fixed. For the full picture of how these loans work, see the complete DSCR loans guide.
Why Does Five Units Change the Underwriting?
Five units is where a building stops being treated like a house and starts being treated like a commercial asset. Income is measured differently, the property is valued on what it earns, and the paperwork gets heavier. Four units or fewer usually means a simpler rent-versus-payment test.
Here is the side-by-side:
| Factor | 1-4 units | 5+ units |
|---|---|---|
| Income measure | Gross rent | Often net operating income |
| Payment tested | PITIA | Annual debt service |
| Valuation | Mix of comps and rent | Income-based |
| Documents | Lighter | Rent roll, leases, operating history |
NOI means net operating income: collected rent minus the costs of running the building, before debt payments. Think taxes, insurance, repairs, management, and utilities the owner pays.
Not every program at this size uses NOI. Some use a gross-rent test, and the two can give different answers on the same building. A property can clear one program and miss another. That is why the first question to any lender is how income is defined.
The five-unit line is also a convention, not a law of physics. Unit-count ceilings vary by program. Some stop at eight units, some at ten, some go higher. Mixed-use buildings, meaning residential units plus a small commercial space, are their own sub-case. Which lenders will take your building is a program decision, and a broker sorts that out before you spend money on an appraisal.
The Qualification Factors, One by One
Qualifying comes down to six checks: coverage, leverage, credit, reserves, property condition, and borrower experience. Coverage and leverage get most of the attention. Reserves and the rent roll sink more files than people expect.
| Factor | What lenders look at | How to strengthen it |
|---|---|---|
| Coverage | NOI against tested payment | Lower leverage, longer amortization |
| Leverage | LTV for your transaction | More down payment |
| Credit | Score tier | Pay down balances before applying |
| Reserves | Liquid cash after closing | Document seasoned funds |
| Property | Occupancy, condition, leases | Stabilize before you apply |
| Experience | Prior rental ownership | Show a track record |
Coverage. 1.00 is where many select programs start, and it is a floor for specific programs, not a universal rule. Banks work the same way in principle. The OCC’s commercial real estate lending handbook tells banks to set minimum coverage guidelines by loan type, which is why the threshold moves from program to program.
Leverage. On a purchase of an investment property, most files land at 75%-80% LTV. LTV is the loan amount divided by the property value. A rate-and-term refinance can reach higher, with a ceiling around 85%. A cash-out refinance tops out around 75%. Unit count can change the cap, so confirm the tier for your building specifically.
Credit. The network’s tiers run 620, 660, 680, and 700. A 620 floor exists in parts of the network. Most programs want around 660. Scores of 700 and up open the strongest leverage.
Reserves. Reserves are liquid cash you hold after closing. They are commonly around 6 months of PITIA, which is the full monthly obligation: principal, interest, taxes, insurance, and any association dues. Loans above $1,500,000 typically step up to about 9 months. A conservative rate-and-term file at modest leverage under $1,500,000 can see reserves waived. Reserves vary by lender, leverage, loan size, and transaction type.
Loan size. Standard programs run up to $3,000,000. Above $2,500,000 the network generally holds to 30-year fixed structures, so a 40-year structure on a very large balance may not be on the table.
A bigger down payment lowers the payment and can lift coverage. It never erases a leverage cap, a credit floor, a reserve rule, or a property restriction. The strongest files pass both tests: enough equity and enough rental coverage. All figures here are typical ranges and subject to lender guidelines. Every file is underwritten individually.
How the Coverage Math Works
The formula is net operating income divided by annual debt service. Keep the units matching. If NOI is annual, so is the payment total.
Run the numbers on a modeled building. Assume NOI is the same in every row, and set it so the interest-only payment produces 1.25x. These are illustrative assumptions, not market data.
| Payment tested | Principal paid? | Modeled coverage |
|---|---|---|
| Interest-only window | No | About 1.25x |
| Fully amortizing, 40 years | Yes | About 1.10x |
| 30-year tail after the window | Yes | About 1.00x |
Same building. Same income. Three different answers, and the only thing that moved is the payment in the denominator.
A longer amortization shrinks the principal-and-interest payment, which lifts the ratio. The interest-only window removes principal from the payment entirely. That is the whole appeal of the structure.
One caution matters more than the formula. Clearing 1.00 is not the same as positive cash flow. DSCR compares income to the debt payment only. Repairs, vacancy, management, and big capital projects sit outside the calculation. A building can clear the test and still eat cash in a bad year.
Which Payment Does the Lender Actually Test?
Ask this before anything else: does the program qualify you on the interest-only payment or on the eventual fully amortizing payment? Some test the first. Others test the second. On a tight deal, that choice can be the difference between clearing and missing.
Picture a building that shows about 1.25x on interest-only and about 1.00x on the amortizing tail. One program approves it on the first number. Another treats the second number as the qualifying figure and asks for more equity or a different structure. Same building, different outcomes.
This is why a broker who sees many lenders’ guidelines earns their keep. Across the wholesale network, the tested payment is one of the least standardized features of the product. Nobody sells it on the brochure.
Then comes payment shock. When the interest-only window ends, principal kicks in and the payment steps up. A 30-year amortizing tail makes that step smaller than people fear, but it is real. Stress-test the building at the post-window payment before you commit. If you plan to refinance or sell before the window closes, the tail may never matter. If you plan to hold, it will.
The trade-offs are plain. No principal paydown during the interest-only years. More total interest over the life of the loan. A balance that stays high for a decade.
Documents to Gather (and Why Each One Matters)
For a 5+ unit building, underwriting leans on property documents more than personal ones. The loan is reviewed on documented income under the applicable program, subject to lender guidelines. Traditional personal-income documentation is largely not the focus. The building’s paperwork is.
Property documents:
- Rent roll: a unit-by-unit list of tenants, rents, and lease dates. The lender checks it against leases and bank deposits.
- Signed leases: they prove the rent roll is real, not aspirational.
- Operating history: trailing income and expenses, so the lender can build NOI.
- Insurance and tax records: they feed the expense side.
- Property management agreement: if a manager runs the building, it affects expense assumptions.
Borrower and entity documents:
- Entity paperwork: operating agreement and good standing for an LLC, subject to lender program eligibility.
- ID and credit authorization: to pull your score and place you in a tier.
- Asset statements: to show reserves and the source of your down payment.
- Schedule of real estate owned: it shows your experience.
Each item answers one question. Does the income exist, is it durable, and can you absorb a bad stretch? Pre-answer those and the deal works with less friction.
Step by Step: How to Prepare and Apply
1. Classify the building. Count the units. Note whether any space is commercial or whether you will live on site.
2. Clean the rent roll. Reconcile rents to leases and deposits. Fix gaps before a lender finds them.
3. Build NOI. Take collected rent and subtract real operating costs. Be honest with the expenses.
4. Test several payments. Run coverage on interest-only, a 40-year amortization, and a 30-year tail.
5. Check leverage and reserves. Match your down payment and cash to the transaction type.
6. Pull your credit. Know which tier you sit in before the file goes out.
7. Ask for the tested payment in writing. Get it from the program, not from assumption.
8. Submit with a complete package. A full file beats a fast one.

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.
Where Files Stall (and Where the Rules Bend)
Most 5+ unit files stall on paperwork or on the tested payment, not on credit. A rent roll that disagrees with the leases is the classic problem. So is an expense line that came in higher than the borrower assumed. Expect friction there.
One practitioner pattern worth knowing: in comparable multifamily files, the building usually looks fine on gross rent and gets tight only once real expenses enter the NOI. Borrowers who ran their own NOI first rarely get surprised. Those who relied on gross rent often do.
Coverage under 1.00. This is available through select lenders in the network, with leverage and terms adjusted. It is not the main road, and you should expect less leverage.
Unit ceilings. A program that stops at eight units cannot take a twelve-unit building. Match the building to the program early.
Mixed-use. A small commercial unit may be fine with some lenders and a dealbreaker with others, so ask early.
Owner living on site. If you plan to occupy a unit, say so up front. It can change how the loan is classified and which programs apply.
Vacant or under-construction buildings. A building with no income has nothing to measure. Stabilize it first, then apply.
Short-term rentals. If you plan to run units as short-term rentals, 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.
Why a 5+ Unit Loan Isn’t Reviewed Like a Home 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. The CFPB’s Regulation Z text treats credit to improve or maintain rental property with more than two units as business-purpose. Compliance Alliance adds that the test is the purpose of the loan, not just the property. For you, that means the building’s income, not a personal debt-to-income formula, drives the analysis.
Is the 40-Year Structure Right for You?
It fits when you want a lower tested payment, expect to refinance or sell before the interest-only window ends, or need coverage to clear on a tight deal. It fits poorly when you plan to hold long-term and care about paying down principal. Honestly, this is a toss-up for many investors. The structure helps coverage today and costs you in total interest later. Which side wins depends on how long you hold.
Cash-out is a separate decision. A cash-out refinance tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation. Seasoning is the waiting period between buying a property and refinancing it. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
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.
Key Terms Defined
NOI (net operating income): collected rent minus operating costs, before debt payments.
Amortization: the schedule over which the loan balance is paid down through principal payments.
Interest-only window: a set period when you pay only interest and the balance does not shrink.
Rent roll: a unit-by-unit list of tenants, rents, and lease dates.
LTV (loan-to-value): the loan amount as a percentage of the property’s value.
PITIA: principal, interest, taxes, insurance, and any association dues in one monthly obligation.
Reserves: liquid cash you hold after closing to cover the payment during a rough stretch.
Frequently Asked Questions
Is DSCR on a five-plus unit building calculated like it is on a duplex?
Often not. Smaller buildings usually use a simple gross-rent test against PITIA. At five units and up, many programs divide net operating income by annual debt service, so expenses reduce the ratio. Some programs still use gross rent. Ask how each one defines income.
Which payment do lenders use to test a 40-year loan?
It depends on the program. Some test the interest-only payment, which gives the highest coverage. Others test the fully amortizing payment, which is stricter. Get the tested payment in writing before you commit to a building.
Can I live in one of the units?
You can raise it with the lender, but it changes the picture. These loans are designed for non-owner-occupied investment properties, and an owner living on site can change which programs apply. Disclose it early so the broker routes the file correctly.
Does the 40-year structure work for a cash-out refinance?
It can, through select lenders. Cash-out tops out around 75% LTV across most of the network, with about 6 months of seasoning common. Above $2,500,000 the network generally holds to 30-year fixed structures. Structure options narrow as the loan grows.
What happens when the interest-only period ends?
The payment steps up as principal begins. A 30-year amortizing tail makes the step smaller than a shorter tail would. Many investors refinance or sell before that point. If you plan to hold, model the post-window payment now.
