DSCR Loan for a 5+ Unit Property (Where Residential Ends)

Yes, you can finance a five-plus-unit building with a cash-flow loan. No, it will not be the residential DSCR loan you used on your duplex or fourplex. At five units the deal crosses a hard line into commercial multifamily, and almost everything about the financing changes on the other side of it. The good news: the underlying logic stays the same. The lender still qualifies the building on its rent, not your income. You just play the same game by commercial rules.

Understand the line and the rest of the deal makes sense.

The four-versus-five cliff

There is no gentle slope between residential and commercial financing. There is a cliff, and it sits between the fourth unit and the fifth.

One-to-four-unit properties are residential. They ride residential DSCR programs, residential appraisal forms, 30-year fixed amortization, and the deepest, most competitive pool of lenders in the market. Five units and up are commercial multifamily — different paperwork, different appraisal discipline, different loan structures, and a different cost of capital. A fourplex and a five-plex can sit side by side on the same street, built by the same developer, and the financing for each lives in a separate universe.

If you are weighing whether to stay under the line, the fourplex DSCR loan is the largest property that keeps you on the friendly residential side. Once you commit to that fifth door, accept that you are now a commercial borrower and plan accordingly.

Why does the convention land exactly at four? It is a legacy of how the secondary mortgage market was built. Residential loan programs were designed around owner-occupied and small-investor housing, and four units became the practical ceiling for that box. Everything heavier got pushed into commercial channels with their own underwriting playbook. The line is arbitrary in the sense that a five-unit building is not five times harder to operate than a four-unit one — but it is rigid in practice, and no lender will bend it. Treat the fifth unit as a category change, not a marginal step up in size.

Still cash-flow qualified — just stricter

Here is what does not change: the loan is still underwritten to the asset. No tax returns, no W-2s, no debt-to-income calculation on you personally. The property has to carry itself, and the coverage ratio is how the lender measures whether it does.

DSCR = Net Operating Income ÷ Annual Debt Service

Notice the shift. On a residential DSCR loan the test is roughly gross monthly rent divided by monthly PITIA. On commercial multifamily the numerator becomes net operating income — gross rent minus a vacancy factor minus real operating expenses like management, maintenance, taxes, and insurance. The lender does not give you credit for top-line rent; it gives you credit for what actually drops to the bottom line after running the building.

Say a 6-unit building grosses $9,000 a month, or $108,000 a year. Strip out a 5% vacancy factor and roughly 35% in operating expenses and you might land near $66,000 of net operating income. If the annual debt service on the loan runs $52,000, the DSCR is about 1.27 — comfortably above the commercial floor. These are illustrative figures to show the mechanics, not a quote. Your actual expenses, vacancy assumptions, and payment will differ, and the lender will use its own underwritten expense ratio rather than the seller’s optimistic pro forma.

Commercial lenders also set the bar higher. Where a residential DSCR program may approve at 1.00, commercial multifamily underwriting typically wants 1.20 to 1.25 or better. The building has to clear more income relative to its debt before the lender is comfortable, because the asset is larger, the tenant turnover is more operationally intensive, and the loan structure carries more refinance risk.

The expense side is where most first-time commercial buyers misjudge their coverage. On a residential DSCR loan you barely think about operating costs — the test runs on gross rent. On a five-plus building the underwriter will impose its own expense ratio, often 30 to 45 percent of gross income depending on the building’s age, the local tax burden, and whether utilities are master-metered or tenant-paid. A seller may hand you a pro forma showing a 20 percent expense load and a glowing cap rate; the lender will normalize that to a realistic figure and your DSCR will fall accordingly. The discipline is simple: build your own numbers from real bills — actual tax assessments, real insurance quotes for the specific building, a market management fee even if you self-manage, and a maintenance and capital-reserve line — then run coverage off that. If the deal still clears 1.20 on conservative expenses, it is a real deal.

The commercial appraisal is a different exercise

On a fourplex the appraiser works a residential form, pulls comparable sales, and attaches a unit-by-unit rent schedule. On a five-plus building the appraiser thinks like an investor.

The dominant method is the income approach: the appraiser estimates the building’s stabilized net operating income and divides it by a market cap rate to arrive at value. If similar buildings in the submarket trade at a 7% cap and your building nets $66,000, the income approach points to roughly $943,000 of value. Comparable sales still matter as a sanity check, but the income approach drives the number — which means the appraisal is effectively a business valuation of the rent stream, not a comp grid of nearby houses.

That has real consequences for your deal:

• Operating expenses are scrutinized. A seller’s pro forma that lowballs management or maintenance will get normalized to market by the appraiser and the underwriter. Underwrite to realistic expenses, not the listing’s best-case math.
• Vacancy and lease quality count. A building full of month-to-month tenants or below-market leases appraises and underwrites more conservatively than one with stabilized, market-rate leases in place.
• Cap rate moves your value more than any single rent. A small shift in the market cap rate swings the appraised value substantially, so the submarket’s investor sentiment is baked directly into your loan amount.

Structure: terms, balloons, and recourse

The loan paper looks different too, and these terms are where commercial borrowers get surprised.

• Shorter terms and balloons are common. Instead of a clean 30-year fixed, expect structures like a 5-, 7-, or 10-year term with a balloon, sometimes amortized over 25 or 30 years but due in full at the term’s end. You finance the building knowing you will refinance or sell before the balloon comes due.
• Pricing sits above residential. A commercial DSCR loan prices higher than a comparable residential deal — a rate premium that reflects the larger asset, the refinance risk, and the smaller lender pool. The exact pricing depends on the building, leverage, and coverage; we keep absolute figures in the rate range above, not in this prose.
• Recourse versus non-recourse is a real negotiation. Smaller commercial multifamily loans are often full-recourse, meaning you personally guarantee the debt. Larger or stronger deals can earn non-recourse treatment, where the lender’s remedy is limited to the property itself. Which one you get depends on loan size, your balance sheet, and the asset’s strength — and it is worth fighting for non-recourse where the deal supports it.
• Reserves run deeper. More units mean more potential vacancy and more capital exposure, so plan on heavier reserve requirements than a residential loan would ask for.

Down payment and what you bring

A commercial DSCR loan asks for more skin in the game than its residential cousin:

• Down payment of 25 to 30 percent is the realistic range, versus 20 to 25 percent on residential. Higher leverage exists but narrows your lender options and worsens pricing.
• Reserves of 6 to 12 months of debt service, sometimes more on larger buildings.
• An entity is standard. Commercial multifamily almost always closes in an LLC or similar entity, both for liability and because commercial lenders expect to lend to a business, not an individual.
• A coverage cushion above 1.20, supported by realistic — not pro forma — operating numbers.

If you are scaling across several buildings rather than buying one in isolation, financing them together can change the math. A blanket portfolio loan across multiple properties lets you underwrite the combined rent stream of several assets under one facility, which can smooth coverage and simplify the capital stack as you grow past the residential line.

Bottom line

At five units the residential DSCR loan ends and commercial multifamily begins — that is the cliff, and it is non-negotiable. The financing still qualifies on the building’s cash flow, but the rules tighten: a net-operating-income coverage test instead of gross rent, a 1.20-plus DSCR target, an income-approach appraisal driven by cap rate, 25 to 30 percent down, deeper reserves, shorter terms with balloons, and a recourse-versus-non-recourse decision to negotiate. Underwrite to real expenses, not the seller’s pro forma, and a five-plus building finances cleanly — just on the commercial side of the wall, where the cost of capital is higher and the analysis is sharper.
