Rental income directly influences a multifamily property’s NOI and therefore its DSCR. When occupancy improves or rents increase, the property’s operating income may rise, potentially strengthening its debt-service coverage. Conversely, vacancies, concessions, below-market rents, or tenant turnover can reduce income. Investors should therefore examine actual operating performance rather than relying only on gross scheduled rent. A realistic DSCR calculation begins with reliable income figures and subtracts appropriate operating expenses before comparing NOI with annual debt service.
Operating expenses are equally important. Property taxes, insurance, maintenance, utilities, management fees, and repairs can reduce NOI even when rental revenue remains unchanged. For example, if a building produces $150,000 in NOI and has $120,000 in annual debt service, its DSCR is 1.25x. If expenses increase enough to reduce NOI to $135,000, the ratio falls to 1.13x. Investors reviewing multifamily investment loans should therefore stress-test their assumptions rather than evaluating the property under only the most favorable scenario.
The same analysis can help buyers compare loans for multifamily homes and owners exploring a multifamily refinance loan. Before taking on new debt, investors can examine whether current rents and occupancy provide sufficient coverage for the proposed payments. Reviewing historical financial statements, current leases, operating expenses, and expected changes can provide a more realistic view of debt capacity. A property’s income-producing ability is particularly important for long-term financing because the building’s cash flow is expected to support the loan over time.
