Residential versus commercial treatment

Lenders generally treat one-to-four-unit properties as residential and five or more units as commercial real estate. That difference changes how a loan is underwritten. A residential lender focuses on the borrower’s income and credit. A commercial multifamily lender focuses on the property: its rent roll, expenses and net operating income (NOI). If you are buying two to four units, see our DSCR loan page and the beginner’s guide to multifamily financing.

The numbers lenders use

Net operating income (NOI) is rental income minus operating expenses such as taxes, insurance, maintenance, management and a vacancy allowance. It excludes mortgage payments.

Debt service coverage ratio (DSCR) is NOI divided by annual loan payments. Many commercial lenders look for a minimum somewhere around 1.20 to 1.25, though it varies by lender and loan type.

Loan-to-value (LTV) caps are commonly in the range of 65% to 80%, depending on the program.

An illustration with made-up figures: a building with $180,000 of annual NOI and $144,000 of annual loan payments has a DSCR of 1.25 ($180,000 ÷ $144,000).

What lenders ask you to provide

Is multifamily right for you?

Multifamily can offer steadier cash flow because income comes from several tenants, and value is tied to income rather than only to comparable sales. It also brings more management work, larger capital needs and more complex financing. Many investors start with two to four units and move up.
