How is a loan on 5+ units different from a 1-4 unit loan?

    By Updated September 2026

    A loan on five or more units is a commercial loan: the lender underwrites the property's net operating income and your experience rather than a residential rent-to-payment ratio, typically at 20 to 25 percent down, with a five to ten year fixed period, a 25 to 30 year amortization, and often a balloon. Appraisals, reserves, and closing costs are all higher, and the lender pool is different.

    Reserves3 to 6 months6 to 12 months of debt service plus replacement reserves

    Ranges vary by lender.

    How income is underwritten

    The lender starts with gross rent, subtracts vacancy (usually 5 to 10 percent even if the building is full), operating expenses (taxes, insurance, utilities, repairs, management at 4 to 8 percent whether you self-manage or not), and a replacement reserve of $250 to $350 per unit per year. What is left is net operating income. The loan is sized so that NOI covers the annual debt service by 1.20 to 1.25, and capped at 75 to 80 percent of value.

    Who lends

    • Local and regional banks. Relationship-driven, full recourse, competitive rates, 5 to 10 year fixed with a reset.
    • Agency small balance (Fannie Mae, Freddie Mac). Usually $1 million and up, stabilized buildings, non-recourse, 5 to 30 year terms.
    • Debt funds and bridge lenders. Value-add and lease-up, higher rates, 12 to 36 months.
    • DSCR lenders. Some go to 8 or 10 units with residential-style underwriting, which can be simpler on small buildings.

    What the file needs

    Trailing twelve-month operating statement, current rent roll, leases, two to three years of tax returns on the property if available, your personal financial statement and schedule of real estate owned, and a management plan.

    Where first-time buyers get stuck

    Understating expenses, ignoring the management fee the lender will impute, thin reserves, and no experience on the team. A property manager with a track record solves the last one.
