The Quick Read: It depends on the program. Standard residential DSCR loans are built for one to four units, and five units moves a building into commercial territory. Some select lenders still review five-plus unit files, with different underwriting.
- Four units or fewer fits the standard residential DSCR lane. Five or more is treated as commercial multifamily.
- Five-unit files lean harder on the building’s income, expenses, and paperwork than on the borrower’s profile.
- Leverage, credit, and reserve figures from standard programs do not automatically carry over to a five-unit file.
- A fourplex keeps the 30-year fixed DSCR path open, and that is why the fifth unit matters so much.
- Clearing a 1.00 coverage ratio does not mean the building cash flows after repairs, vacancy, and management.
You found a five-unit building, ran the rents, and now want to know if a DSCR loan fits. The honest answer is that the product changes at the fifth door. This article explains why, what the loan looks like once you cross that line, and how to decide between five units and four.

DSCR stands for debt service coverage ratio, a test of whether a property’s rent covers its own payment. Lendmire is a mortgage broker that arranges DSCR investor loans through select lenders in its wholesale network. It does not make the final call on any file. Lenders do, after reviewing the borrower, the property, and the loan. The sections below are written from that broker’s seat, looking across many lenders’ guidelines.
Why Does Five Units Change the Rules?
Five units is where lenders stop treating a building as a residential property and start treating it as commercial multifamily. The line is a financing convention, not a physical one. A fourplex and a five-unit building can look nearly identical from the street.
Most residential DSCR programs across the network are written around one to four units. Underwriting, appraisal, documents, and loan structure all assume a small residential building. Once you pass four units, those assumptions break. The deal works to a commercial framework, or to a specialty program that a few select lenders run for small multifamily.
The appraisal shows the split clearly. Fannie Mae’s Selling Guide lists Form 1025, the small residential income property appraisal report, for two- to four-unit properties. Form 1004 covers one-unit properties. Neither form is built for five units, so the appraisal process changes. DSCR loans are not agency products, so treat this only as a picture of where the residential world ends.
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.
Why You Hear Both Yes and No
Some sources say DSCR loans stop at four units. Others say five- to eight-unit DSCR loans exist. Both can be true, because people use “DSCR loan” to mean two different things.
One meaning is a standard residential DSCR program. Those stop at four units. The other meaning is any loan underwritten mainly on a property’s income coverage. That broader style also exists for small multifamily, but terms, leverage, and lender availability look different. If a page answers yes or no without saying which one it means, discount the answer.
What Are Your Financing Options on a 5-Unit Building?
You have roughly three realistic paths on a five-unit building: a DSCR-style program through a select lender, a commercial bank loan, or short-term bridge financing. Each trades off differently on how it judges the deal, how much paper it wants, and who it suits.
| Option | Judged mainly on | Paperwork load | Best fit |
|---|---|---|---|
| Select-lender DSCR, 5+ units | Building income vs. debt | Moderate to heavy | Stabilized, income-driven buyers |
| Commercial bank loan | Building and borrower | Heavy | Borrowers with bank relationships |
| Bridge financing | Exit plan and asset | Varies | Value-add or unstabilized buildings |
Commercial bank loans often come with a personal guarantee, meaning you are personally on the hook if the loan goes bad, even when an LLC holds title. Some commercial loans are non-recourse, which limits the lender to the property itself, but those versions usually price differently.
Select-lender DSCR files at this size are the middle path. They keep the property-income focus that investors like, but they are not the same loan a fourplex gets. Lendmire’s piece Investor Cash-Out Refinance Requirements on a 5+ Unit Building covers the refinance side in depth.
Which path fits depends on the investor profile, the property, the program, and current lender guidelines. Be wary of anyone who promises a single answer before seeing the building.
How Is DSCR Calculated at Five Units?
On a residential DSCR loan, the lender compares monthly rent to the full monthly payment. On five-plus units, lenders often compare net operating income to debt service instead. The two methods can give very different numbers for the same building.
The residential-style formula is simple:
DSCR = monthly rent ÷ monthly PITIA
PITIA is principal, interest, taxes, insurance, and any association dues. The commercial-style formula works from the building’s operating results:
DSCR = net operating income ÷ annual debt service
Net operating income, or NOI, is rental income minus the costs of running the building: vacancy, repairs, management, utilities the owner pays, and similar items. It leaves out the loan payment itself. Annual debt service is what you pay the lender over twelve months.
One Building, Two Answers
Here is an illustrative example. These are modeled assumptions, not market data. Say a five-unit building shows 1.30x coverage when you divide gross rent by the full monthly payment. Now say operating costs outside the loan take about a quarter of the rent. That leaves 75% of rent as income, so the same building lands near 0.98x on the NOI method. The result is simplified, but the point holds: a building that clears 1.00 on gross rent can fall just under it once real expenses come out.
Neither number is wrong. They answer different questions. This is why you should ask any lender which method they use before you trust an early coverage estimate.
Coverage at 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. At five units, expect lenders to want more cushion over 1.00 rather than less, because NOI-based math is stricter.
What Changes at Five Units Compared With Four?
Almost everything about the process gets heavier at five units: the appraisal, the documents, the lender pool, and the loan structure. The table summarizes the pattern at the category level.
| Factor | 1-4 units | 5+ units |
|---|---|---|
| Classification | Residential | Commercial multifamily |
| Appraisal | Comparable sales | More income-focused |
| Income test | Rent vs. PITIA | Often NOI vs. debt service |
| Documents | Lighter | Rent roll, leases, operating history |
| Loan structure | 30-year fixed spine | Varies by lender and program |
| Lender pool | Wide | Narrower, select lenders |
Appraisals on larger buildings tend to cost more and weigh actual rents and operating results more than comparable sales. Projected rents usually count for less than the rents tenants pay today. That matters if you are buying a half-vacant building with a plan to raise rents.
A fourplex keeps the full residential toolkit available. That includes a 30-year fixed structure, with extended terms and interest-only periods available through select lenders in the network. Five-unit structures vary by lender and program, and a shorter runway with a balloon payment is common on commercial loans. A balloon is a lump sum due at the end of a shorter loan term.
What Do Leverage, Credit, and Reserves Look Like?
Across the network, standard residential DSCR programs typically run 75%–80% LTV on an investment property purchase. LTV is loan-to-value, the loan as a share of the property’s value. Select high-leverage programs reach 85% LTV with roughly a 700+ score. Cash-out refinances top out around 75% LTV on standard rentals. These are residential-program figures, subject to lender guidelines.
Do not assume those numbers carry to a five-unit file. Five-plus unit loans often come with lower leverage, higher credit expectations, or both. The right way to use the figures above is as a reference point for what a fourplex might get. Lower leverage on the fifth door is normal.
Credit works in tiers. A 620 floor exists in parts of the network, and most programs want around 660. A score of 700 or better unlocks the strongest leverage. Loan sizes on standard programs run up to $3,000,000, and structures above $2,500,000 generally hold to 30-year fixed terms.
Reserves are cash you keep after closing to cover payments if rents slip. They vary by lender, leverage, loan size, and transaction type. Commonly it is around six months of PITIA, with about nine months on loans above $1,500,000. Larger buildings tend to draw more attention to reserves, since one vacancy matters less but several matter more.
Remember what the ratio does not measure. Clearing 1.00 means the rent covers the payment. It does not mean the building makes money after repairs, vacancy, management, utilities, and capital expenses. A five-unit building has more of all of those.
What Should You Have Ready to Apply?
Plan for a heavier file than a fourplex would need. A lender reviewing a five-unit building wants to see how the building actually performs, not just what it could rent for. Gather these before you start:
- Rent roll: a unit-by-unit list of tenants, rents, and lease dates.
- Leases: copies for every occupied unit.
- Operating statements: a trailing record of income and expenses.
- Entity documents: if an LLC will hold title, its formation papers, subject to lender program eligibility.
- Reserve proof: statements showing liquid funds.
- Property details: condition, occupancy, and any deferred maintenance.
The strongest files clear two tests at once. You need enough equity for the leverage cap, and you need enough rental coverage for the income test. A bigger down payment lowers the payment and can lift the ratio, but it never erases credit floors, reserve rules, or property eligibility.
Occupancy matters too. Lenders usually prefer a stabilized building with most units rented. A mostly empty building may point you toward bridge financing first, then a longer-term loan once leases are in place.
Can You Buy, Refinance, and Cash Out?
You can pursue all three transaction types at five units, but each has its own limits. A purchase leans on the income test and down payment. A refinance leans on income and equity. A cash-out refinance leans hardest on seasoning, which is how long you have owned the property, with about six months common across the network.
Run a purchase scenario like this. Picture an investor buying a five-unit building with an NOI-based coverage near 1.15x and a 25% down payment. That file has real cushion over 1.00. If an inspection later turns up deferred roof work, though, the investor may need reserves or a repair plan to keep the lender comfortable. A file at 1.15x with thin reserves can look weaker than a 1.05x file with plenty. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Cash-out follows the same logic. If you own a fourplex and are comparing a fifth unit through an addition or a separate purchase, remember that cash-out leverage tops out around 75% on standard rentals. Five-unit programs may sit lower.
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.
What About Mixed-Use, Short-Term Rentals, and Condition?
Special cases tighten the file further. Mixed-use buildings, which combine apartments with commercial space, depend on how much of the building is commercial. Thresholds vary by program, so the share of commercial space is a question for the lender before you make an offer.
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. On the loan side, short-term rental programs have their own parameters. Purchases go to 75% LTV with about 12 months of hosting history expected, and cash-outs sit at 70%. Those are separate from the long-term rental tiers above. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Property condition matters more at this size. Deferred maintenance on a five-unit building can swing the file. Property types such as manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs, so confirm the building’s construction early.
Tax treatment can depend on how the funds are used and how the property is held, and unit count does not change the 27.5-year residential rental schedule described in IRS Publication 527, so investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
What If Your Coverage Comes Up Short?
A low ratio gives you levers to pull. In rough order of practicality:
1. Check the expense side. Confirm that the operating costs the lender counted are actual, not rounded up.
2. Raise rents where leases allow. Lenders at this size usually credit actual rents, not projections, so this helps most once new leases are signed.
3. Add down payment. More equity lowers the payment and lifts the ratio, within the leverage cap.
4. Change the structure. Select lenders in the network offer extended terms and interest-only periods that can improve coverage.
5. Look at a lower-coverage path. Programs below 1.00 are available through select lenders in the network, with leverage and terms adjusted.
6. Reconsider the building. A fourplex with slightly lower rent may finance more cleanly.
Qualification stays subject to lender guidelines, credit approval, and property review.
What Are the Trade-Offs Against a Fourplex?
A fourplex is easier to finance, but a five-unit building can be a better business. The fourplex gives you a wider lender pool, a lighter appraisal, and the 30-year fixed spine. The five-unit building gives you one more rent stream, and it can spread fixed costs across more doors. Management can also run more efficiently at larger scale.
The cost is friction. Expect more paper, fewer lenders, a different loan structure, and possibly lower leverage. It is a genuine toss-up for some investors. If the five-unit building is clearly the better asset, the friction is worth paying. If the two buildings are close, the fourplex’s cleaner financing can tip the decision.
Common mistakes at this size:
- Assuming fourplex terms carry over to five units.
- Using gross rent to judge coverage when the lender will use NOI.
- Treating a 1.00 ratio as proof of positive cash flow.
- Ignoring the appraisal’s income focus when buying a partly vacant building.
- Skipping the lender conversation until after going under contract.
Key Terms Defined
DSCR (debt service coverage ratio): a measure of whether a property’s income covers its debt payment.
PITIA: principal, interest, taxes, insurance, and association dues, the full monthly housing obligation.
NOI (net operating income): rental income minus operating costs, before the loan payment.
LTV (loan-to-value): the loan amount as a percentage of the property’s value.
Recourse: a lender’s ability to pursue you personally if the property does not cover the debt.
Rent roll: a unit-by-unit schedule of tenants, rents, and lease terms.
Reserves: liquid cash you hold after closing to cover payments if income dips.
Frequently Asked Questions
Why can’t a five-unit building be treated like a fourplex?
Because lenders classify five or more units as commercial multifamily. The appraisal, income test, documents, and loan structure all change. A fourplex stays inside the residential framework, which is why the fifth unit matters so much.
Do I need traditional personal-income documentation and W-2s?
A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Five-unit files usually ask for more property paperwork, such as a rent roll and operating history. Requirements differ by lender and program.
Can I buy a five-unit building in an LLC?
Many investors do, and an LLC can hold title subject to lender program eligibility. Commercial lenders may still ask for a personal guarantee behind the entity. Ask about recourse before you commit to a structure.
Does a mixed-use building count?
It can, depending on how much of the building is commercial space. Each program sets its own limit. Confirm the share of commercial space with a lender before you make an offer.
Can I do a cash-out refinance on five units?
Yes, on programs that review the building, though leverage and terms differ from a fourplex. On standard rentals the network tops out around 75% LTV on a cash-out, with about six months of seasoning common. Five-unit programs may sit lower. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
