Fannie Mae multifamily requirements in context

Fannie Mae multifamily financing serves stabilized US apartment buildings with five or more units meeting agency underwriting grids. Requirements center on normalized NOI, coverage metrics, asset quality, and sponsor capacity—not residential borrower income tests.

Core underwriting metrics

Agency sizing uses the tightest of:

• DSCR on normalized in-place NOI (directionally about 1.25x on many conventional Tier 2 executions)
• Debt yield floors that vary by market and product
• LTV caps tied to appraisal and grid (conventional Tier 2 often up to about 80%)

Use the commercial DSCR calculator and loan sizing tool before quoting.

Stabilization and occupancy expectations

Agency lenders favor durable physical and economic occupancy with credible rent roll support. Transitional lease-up stories usually belong in bridge execution until stabilized metrics are achievable.

Sponsorship and legal structure

Expect guarantor financials, entity documentation, and experience narrative—especially on smaller sponsor teams or emerging markets. SPE covenants and post-close reporting are standard.

Agency vs alternatives

When Fannie Mae grid constraints bind—or timeline requires speed—compare agency vs bridge and CMBS vs agency. Read agency stabilized loan type for product detail.
