Agency debt is long-term, mostly fixed-rate multifamily mortgage financing originated through the lender networks of Fannie Mae and Freddie Mac, the government-sponsored enterprises. These loans fund stabilized apartment and affordable housing at up to 80% loan-to-value, are typically non-recourse, and are pooled and sold to bond investors under a federal purchase cap.
What Is Agency Debt?
Agency debt is multifamily financing sourced from the two housing government-sponsored enterprises, Fannie Mae and Freddie Mac, through their approved lender programs. Fannie Mae uses its DUS network of delegated lenders who share loss risk, while Freddie Mac uses its Optigo seller-servicer network. Both target stabilized apartments and prioritize mission-driven affordable and workforce housing.
Terms are standardized and borrower-friendly for qualifying properties. Per Fannie Mae's Multifamily Guide and Freddie Mac program materials, common parameters are a maximum 80% loan-to-value, a minimum 1.25x debt service coverage on Fannie Mae DUS loans, and fixed-rate terms of 5, 7, 10, 12, 15, and up to 30 years, with 30-year amortization and non-recourse structure standard.
Agency debt parameter | Representative term (2026) |
Program | Fannie Mae DUS, Freddie Mac Optigo |
Property type | Stabilized multifamily, 5 or more units |
Maximum loan-to-value | Up to 80% |
Minimum DSCR | 1.25x (Fannie DUS), 1.20x and up (Freddie SBL) |
Term | 5 to 30 years, fixed rate common |
Recourse | Non-recourse with standard carve-outs |
The government-sponsored enterprises do not lend limitless volume. Per the FHFA, the 2026 multifamily loan purchase caps are $88 billion each for Fannie Mae and Freddie Mac, a combined $176 billion, up 20.5% from the $73 billion each set for 2025.
Why Agency Debt Matters
Agency debt matters because it is the largest and most reliable source of permanent multifamily financing in the United States, available across the cycle even when banks and CMBS retreat. Because the government-sponsored enterprises buy and securitize these loans, capital flows to apartments steadily, which is why agency debt anchors most stabilized multifamily capital stacks.
The trade-offs are eligibility and mandate. Per the FHFA, at least 50% of the enterprises' 2026 multifamily business must be mission-driven affordable housing, so agency programs favor apartments over most other property types and reward affordability. Rate locks are a distinctive advantage, with agency loans commonly offering 30 to 90 day locks and early rate lock options extending up to 180 days, which lets a borrower fix a coupon well before closing.
The quotable point for an operator: agency debt is the cheapest, longest, most dependable permanent money for stabilized apartments, but only for apartments, and the government-sponsored enterprises price and allocate it around an affordability mandate rather than pure yield.
Example
A sponsor finances a stabilized $25,000,000 apartment property with a Fannie Mae DUS loan. The lender sizes the loan against the 80% loan-to-value ceiling and the 1.25x debt service coverage minimum, then takes the lower result. The table shows both tests.
Item | Calculation | Result |
Property value | Given | $25,000,000 |
LTV-constrained loan | 80% x $25,000,000 | $20,000,000 |
Net operating income | Given | $1,450,000 |
Max annual debt service at 1.25x | $1,450,000 / 1.25 | $1,160,000 |
Assumed constant | Given fixed rate and amortization | 7.20% |
DSCR-constrained loan | $1,160,000 / 0.0720 | about $16,111,000 |
Loan proceeds | Lower of the two tests | about $16,111,000 |
The 80% test allows $20,000,000, but the 1.25x coverage test caps proceeds at roughly $16,111,000, so the debt service coverage constraint binds and the borrower receives about $16.1 million. Coverage, not the loan-to-value ceiling, sizes most agency loans in a higher-rate environment, because a lower coupon would raise the DSCR-constrained amount toward the LTV cap.
Variations and Edge Cases
Agency programs are not uniform: Fannie Mae and Freddie Mac run distinct products for different loan sizes and property missions. The table below covers the main variants.
Variant | Treatment |
Fannie Mae DUS | Delegated lenders share loss risk; standard for stabilized apartments |
Freddie Mac Optigo | Seller-servicer network; conventional and targeted affordable products |
Freddie Mac SBL | Small balance loans from about $2,000,000 to $10,000,000 |
Affordable and LIHTC | Preferential treatment; loans excluded from caps if mission-driven |
Workforce housing | Excluded from the 2026 caps to encourage supply |
A frequent point of confusion is the word agency. In multifamily, agency debt means the housing government-sponsored enterprises, Fannie Mae and Freddie Mac. It does not mean Ginnie Mae or FHA-insured multifamily lending, which is a separate government program with its own terms and longer, fully amortizing structures.
Agency Debt vs CMBS
Agency debt is often confused with a CMBS loan, and both are securitized non-recourse commercial mortgages, but they serve different property sets and lenders. Agency debt comes from Fannie Mae and Freddie Mac and finances only multifamily, with an affordability mandate and standardized terms. A CMBS loan is a conduit product from private lenders that finances all commercial property types and pools loans for private bond investors.
The practical difference is availability and flexibility. Agency debt is deeper, cheaper, and steadier for apartments across the cycle, but it is limited to multifamily and constrained by federal caps. CMBS reaches office, retail, industrial, and hotels, but it prices to the private bond market and can pull back sharply when credit tightens.
