You know how DSCR works on a duplex or fourplex. Add one more unit and the formula changes, and the same building can suddenly look much tighter.
In short: Yes, you can get a DSCR-style loan on a 5+ unit property, but it is calculated differently. On 2–4 units, DSCR is usually gross rent divided by the monthly payment including taxes and insurance. On 5+ units, it is net operating income, after vacancy and all operating expenses, divided by annual debt service. LendingStreet finances both, and knowing which formula applies keeps your offer price realistic.
Residential financing rules cover one to four units. Once a building has five or more, it is treated as multifamily, which most programs handle as commercial.
Commercial underwriting looks at the building as a business. It counts every operating cost, not just the mortgage, taxes and insurance.
The residential version is simple and generous. The multifamily version subtracts more before it compares income to the loan payment.
| 2–4 units (residential DSCR) | 5+ units (multifamily) | |
|---|---|---|
| Income used | Gross monthly rent | NOI after vacancy and expenses |
| Compared to | Principal, interest, taxes, insurance, HOA | Principal and interest |
| Expenses counted | Taxes, insurance, HOA | All operating costs |
| Typical minimum | 1.0x on standard programs | Varies, often higher than 1.0x |
This example is illustrative. A 6-unit building rents for $8,400 a month. The loan is $700,000 at an illustrative 7.0% rate on 30-year amortization, about $4,657 a month in principal and interest.
Using the residential method, add $900 in taxes and $400 in insurance for a total payment of $5,957. The ratio is about 1.41x. Using the NOI method, the ratio drops to about 1.06x.
| NOI method | Annual |
|---|---|
| Gross rent | $100,800 |
| Less 5% vacancy | −$5,040 |
| Taxes and insurance | −$15,600 |
| Repairs, utilities, management, reserves | −$21,160 |
| NOI | $59,000 |
| Principal and interest | $55,885 |
| Coverage | ≈1.06x |
If you price a 6-unit building with residential math, you will overestimate the loan. Run the NOI method before you sign a contract.
Use real expense figures from the seller’s operating statement. If the seller has none, underwriters will apply market assumptions, and those are rarely generous.
A few levers move the ratio more than others. Most of them are under your control before closing.
A 5+ unit building with a storefront or office on the ground floor is usually financed as mixed-use. The commercial income is counted, but underwriters often apply a higher vacancy assumption to it.
Short-term rental buildings with five or more units are also financed by some programs. Income is based on projected or actual short-term revenue, and requirements are stricter than for long-term leases.
If you already own the building, include your trailing 12-month operating statement and current leases. If you are buying, ask the seller for the same before your inspection period ends.
Send the rent roll, expenses and price or payoff. Your loan officer will run the NOI calculation the way underwriting will. Our financing team typically returns 2–3 options, often within 48 hours.
Yes, but it is underwritten on NOI rather than gross rent over the monthly payment. That usually produces a lower ratio. We finance 5+ unit buildings with programs built for that method.
It varies by program. NOI-based multifamily programs often want more cushion than the 1.0x floor used on standard residential DSCR loans. Loan size and property condition also affect the requirement.
Not on our programs. The building qualifies on its operating income. You provide a rent roll, operating statement, credit and proof of reserves.
Because the 5+ unit method subtracts vacancy and all operating expenses before comparing income to the loan payment. The residential method only subtracts taxes, insurance and HOA. The same rent supports less debt under the NOI method.
Our programs start around $150K. Smaller buildings in lower-cost markets can qualify. Larger buildings can go well into the millions.
It depends on your goals. A fourplex uses residential DSCR math, which is usually more forgiving. A 5-unit adds income but moves you to NOI-based underwriting, so run both numbers before you choose.

Properties with 5+ units are commercial by definition, so they fall outside Fannie/Freddie residential programs. But at 5-20 units the loan is usually too small for institutional multifamily desks, whose minimums and timelines are built for 50+ unit assets. The result is a financing gap: too big for residential, too small for institutional.
Through DSCR-based and bridge capital sources that underwrite to the property's net operating income rather than agency checklists. Typical structures: purchase or refinance at up to 75% LTV, 5-20 units, $200K-$20M, with bridge-to-perm available for value-add and lease-up plays.
Stabilized small multifamily DSCR loans typically close in 14-21 days. Bridge structures for value-add acquisitions can close in 5-10 days, then refinance into permanent DSCR financing after stabilization.
No. These programs underwrite the property's income (NOI / DSCR), not your tax returns. LLC borrowers are standard, and there is no W2 requirement.
Mixed-use with a residential majority (for example, apartments over retail) can be placed through commercial and mixed-use capital sources through the same LendingStreet application, with custom terms up to $5M+.
