Agency Debt: Why Fannie and Freddie Are Multifamily's Default Lenders

What agency debt is

Fannie Mae and Freddie Mac don't lend directly. Fannie operates through DUS (Delegated Underwriting and Servicing) lenders who share risk on each loan; Freddie buys loans from its Optigo network and securitizes most of them. Either way, the sponsor's experience is similar: you borrow from an approved originator, and the GSE's standards set the terms. Congress chartered both to keep rental housing liquid — which is why agency money stays available in downturns and why its pricing is hard for banks to beat on stabilized assets.

Both agencies lend on conventional apartments, affordable housing, seniors housing, student housing, and manufactured-home communities. Both run small-loan programs (roughly the $1–9 million range) with streamlined processing — relevant for sponsors moving up from small multifamily toward institutional scale.

What the loans look like

Two structural features deserve special attention. Non-recourse means the lender's remedy is the property, not the sponsors' balance sheets — but the carve-out guarantees (fraud, misapplication of funds, unauthorized transfers, environmental) are personal, and key principals sign them. And prepayment protection cuts both ways: yield maintenance makes an early sale or refi genuinely expensive, while assumability can make your loan an asset at exit — a below-market assumable loan has sold many properties in high-rate environments.

Qualifying: the property, then the sponsor

Agency underwriting is formulaic, which is its virtue — you can compute your loan size before you ever talk to a lender. The loan is the smallest number produced by the LTV cap, the DSCR floor at the actual note rate, and (for some executions) a debt-yield test. Sizing inputs are the agency's normalized numbers, not yours: underwritten vacancy floors (commonly ~5% minimum even if the property runs tighter), market-standard management fees, and mandated replacement reserves all come out of NOI before the ratio is computed.

1. The property must be stabilized — commonly ~90% occupancy for ~90 days — physically sound, and in a market the agencies like. Heavy-rehab stories are bridge-loan territory until stabilized.
2. Key principals need experience, net worth, and liquidity — a common bar is net worth around the loan amount and liquidity around 9–12 months of debt service, across the guarantor group. First-time sponsors typically satisfy this by bringing an experienced co-GP or loan sponsor into the general partnership.
3. Expect full third-party diligence: appraisal, physical condition assessment, environmental Phase I — budget the reports and the 45–75 day timeline into your contract dates.
4. Ownership structure gets reviewed: the agencies underwrite the borrower entity, its key principals, and anyone with significant control. Syndication structures are routine, but disclose them early — surprises at closing are how rate locks die.

Agency debt in a syndication

For sponsors, agency debt shapes the deal you can offer investors. The long fixed term removes refinance risk from the hold period; the interest-only years front-load cash-on-cash returns; non-recourse structure is a genuine LP talking point. The costs are flexibility — yield maintenance effectively marries you to the hold plan — and the sizing discipline, which frequently produces smaller proceeds than a sponsor's optimistic model assumed.

• Underwrite loan proceeds at agency standards from day one: their vacancy floor, their reserves, their DSCR at the quoted rate. The gap between 'what the model wants' and 'what the agency sizes' is the most common cause of last-minute equity holes.
• Match the loan term to the business plan — a 10-year yield-maintenance loan under a 3-year value-add plan means either a painful prepay or a plan to sell the loan's assumability.
• Disclose the debt structure in the offering documents: term, rate, IO period, prepayment protection, carve-out guarantors, and what each means for investor returns and exit flexibility. Sophisticated LPs read the debt page first — the debt is the deal's skeleton.
• Bridge-to-agency is the standard value-add sequence: bridge funds the renovation, agency debt is the takeout. Underwrite the takeout at stressed rates before you close the bridge (see our bridge-loan guide) — the agency's sizing floor is what catches over-levered plans.
