How to Finance a Multifamily Property With 5+ Units: Loan Options, Rates, and What to Expect

The Moment Everything Changes: 5 Units and Above

If you own a duplex or a fourplex, you are in the residential lending world. The loan process looks similar to buying a single-family home. Fannie Mae and Freddie Mac guidelines apply. DSCR loans work the same way they do for any 1-to-4 unit property. Your lender evaluates the property, checks your credit, and closes in 21 to 30 days.

The moment you step up to a 5-unit building, everything changes. Five units is the threshold where residential lending ends and commercial lending begins. The underwriting is different. The terms are different. The documentation is different. The way lenders evaluate the property is fundamentally different. And for investors who do not understand these differences, the jump from 4 units to 5 can be confusing, expensive, or both.

This guide walks through every financing option for multifamily properties with 5 or more units. We cover DSCR loans for small multifamily (5 to 8 units), commercial loans for larger buildings (10+ units), bridge loans for value-add multifamily plays, and the key financial metrics you need to understand before you talk to a lender. At the end, we walk through a complete sample deal on a 12-unit building.

Key Financial Metrics Lenders Use for 5+ Unit Properties

Before you approach a lender for a multifamily deal with 5 or more units, you need to understand four numbers. These are the metrics that drive every commercial real estate lending decision.

Net Operating Income (NOI)

NOI is the total rental income from all units minus all operating expenses. Operating expenses include property taxes, insurance, property management fees, maintenance, utilities (if owner-paid), vacancy allowance, and reserves for capital expenditures. NOI does not include debt service (your mortgage payment). It is the income the building generates before you pay the lender.

Example: A 12-unit building with gross rental income of $156,000 per year ($1,083 average rent per unit per month) and operating expenses of $62,400 per year has an NOI of $93,600.

Capitalization Rate (Cap Rate)

The cap rate is NOI divided by the property value (or purchase price). It is the unleveraged yield on the property. A building with $93,600 in NOI purchased for $1,170,000 has a cap rate of 8.0%. Cap rates vary dramatically by market, property class, and building condition. In 2026, cap rates for stabilized multifamily buildings range from about 5.0% in strong urban markets to 9.0% or higher in secondary and tertiary markets. The cap rate is also used by appraisers to determine property value. If a lender's appraiser uses a 7.5% cap rate instead of 8.0%, the same $93,600 NOI produces a value of $1,248,000 instead of $1,170,000.

Debt Service Coverage Ratio (DSCR)

You already know DSCR from residential lending: income divided by the mortgage payment. In commercial multifamily, the calculation uses NOI instead of gross rent. DSCR equals annual NOI divided by annual debt service (total principal and interest payments for the year). Most commercial lenders require a minimum DSCR of 1.20 to 1.25 on multifamily deals. Some agency lenders (Fannie Mae, Freddie Mac) require 1.25 as a firm minimum.

Debt Yield

Debt yield is NOI divided by the loan amount. It measures the lender's return on their investment if they had to take the property back. A building with $93,600 NOI and an $819,000 loan has a debt yield of 11.4%. Most commercial lenders require a minimum debt yield of 8% to 10%. This metric has become increasingly important since 2023 as a secondary check on deal quality, especially in markets where cap rates have compressed.

Commercial Loans for Larger Multifamily (10+ Units)

Once you move beyond 8 units, you are firmly in commercial loan territory. The underwriting becomes more rigorous, the documentation requirements increase, and the loan structures look very different from residential financing. But the trade-off is worth it: commercial lenders will finance much larger deals, and the terms often include features that make portfolio-level investing more manageable.

Types of Commercial Multifamily Lenders

• Local and regional banks: Often the most accessible option for 10-to-30 unit buildings. They hold loans in portfolio, which gives them flexibility on terms. Rates are typically 6.750% to 8.000% with 5-to-10 year terms and 25-to-30 year amortization. LTV usually caps at 70% to 75%. These banks want to see a strong rent roll, a T-12, and the borrower's personal financial statement and tax returns.
• CMBS lenders (Commercial Mortgage-Backed Securities): These lenders pool commercial loans into securities and sell them on the secondary market. CMBS loans work well for stabilized properties with loan amounts above $2 million. Rates are competitive (6.500% to 7.500% in Q1 2026), but the underwriting is rigid and closing takes 45 to 75 days. Prepayment is typically yield maintenance or defeasance, which makes early payoff expensive.
• Agency lenders (Fannie Mae / Freddie Mac multifamily): Available for stabilized properties with 5+ units. These offer the best terms in the market: rates in the 6.250% to 7.250% range, 30-year fixed options, and up to 80% LTV for affordable housing. The minimum loan amount is typically $750,000 to $1,000,000. Underwriting is thorough but standardized. Close time is 45 to 60 days. These are the gold standard for buy-and-hold multifamily financing.
• Debt funds and private lenders: More flexible than banks or agencies, but more expensive. Rates range from 8.000% to 11.000%. These lenders are useful when the building does not meet agency or bank requirements, such as low occupancy, deferred maintenance, or short operating history. Terms are typically 3 to 5 years with interest-only options.

What Commercial Lenders Require

• Current rent roll (unit-by-unit breakdown of tenants, lease terms, and rents)
• Trailing 12-month operating statement (T-12) showing actual income and expenses
• Two years of property tax returns (or building financial statements)
• Personal financial statement and tax returns of the guarantor(s)
• Entity documentation (operating agreement, articles of organization)
• Property condition report and/or Phase I environmental assessment (for larger deals)
• Insurance declaration page with adequate coverage

Sample Deal: Financing a 12-Unit Building

Let us walk through a real scenario. You find a 12-unit apartment building in a mid-size Midwest metro. The building is 83% occupied (10 of 12 units leased), rents are slightly below market, and the property needs about $120,000 in renovations to bring it to full market rate. Here is how the financing works.

Post-Renovation Projected Numbers

The Financing Strategy: Bridge Then Permanent

Step 1: Acquire with a bridge loan. Total project cost is $1,080,000 ($960,000 purchase + $120,000 renovation). A bridge lender at 80% loan-to-cost funds $864,000. You bring $216,000 in cash to closing (including closing costs and reserves). The bridge rate is 10.5% interest-only for 24 months. Monthly interest payment: $7,560.

Step 2: Renovate and stabilize. Over 8 to 12 months, you renovate the two vacant units and the common areas, turn over leases to market rate as existing tenants renew, and fill the building to 100% occupancy at $1,075 per unit.

Step 3: Refinance into permanent financing. Once the building is stabilized at 95%+ occupancy with the $85,295 NOI, you refinance with a commercial or agency loan. Using a 7.0% cap rate, the building appraises at approximately $1,218,500. A 70% LTV permanent loan gives you $852,950. That pays off most of the bridge loan, and your annual debt service on the new permanent loan at 7.0% over 25 years is approximately $72,300. Your DSCR is $85,295 / $72,300 = 1.18. That is tight for some lenders but workable, especially if the NOI continues to grow.

The Return

You invested $216,000 in cash, created $138,500 in equity through the renovation and rent increases, and now generate roughly $13,000 per year in cash flow after debt service. The total return on your cash investment, including the forced appreciation, is over 70%. That is the power of value-add multifamily when the financing is structured correctly.

The Bottom Line

Financing a multifamily property with 5 or more units is not harder than financing a single-family rental. It is different. The underwriting shifts from borrower-focused to property-focused. The metrics change from simple DSCR to NOI, cap rate, and debt yield. The documentation requirements increase. And the loan structures include terms like balloon maturities, yield maintenance, and interest-only periods that do not exist in residential lending.

But for investors who understand these differences, multifamily is where the real wealth building happens. A single 12-unit building can generate more cash flow than a dozen single-family rentals, with less management overhead per unit, stronger economies of scale, and the ability to force appreciation through operational improvements.

Whether you are looking at a small 6-unit with a DSCR loan, a 20-unit value-add with a bridge loan, or a 50-unit stabilized building with a commercial loan, the financing exists. The key is matching the right product to the right deal at the right stage of the investment. Sinai Capital has funded multifamily deals from 5 units to 100+ units across every loan type.
