Agency debt is the backbone of multifamily finance in the United States: long terms, high leverage, non-recourse, and pricing most banks cannot match on stabilized apartment deals. But there is a structural detail that surprises many first-time sponsors — Fannie Mae and Freddie Mac do not lend to borrowers. Every agency multifamily loan is originated, and usually serviced, by a private lender that holds a coveted seat in one of two approved networks: Fannie Mae's DUS program or Freddie Mac's Optigo network.
Understanding how those networks work — who is in them, how the risk is shared, and why quotes still vary between approved lenders — is the difference between taking the first agency quote you receive and running a real process.
What is an agency multifamily loan?
An agency multifamily loan is a mortgage on an apartment property (typically five or more units) that is funded or purchased by one of the government-sponsored enterprises, Fannie Mae or Freddie Mac, through their approved lender networks. Agency loans are prized for high leverage — commonly up to around 80% LTV with a minimum underwritten DSCR near 1.25x — long terms, competitive fixed rates, and non-recourse structure with standard carve-outs.
Because the agencies exist to support housing liquidity, this capital is multifamily-only: it does not finance office, retail, industrial, or hotels. For a comparison of agency debt against the rest of the multifamily menu, see our guide to multifamily CRE loans in 2026.
Who are the approved lenders for agency multifamily loans?
Approved lenders for agency multifamily loans are the members of two networks: Fannie Mae's DUS (Delegated Underwriting and Servicing) lenders — a small group of roughly two dozen firms — and Freddie Mac's Optigo network of approved seller/servicers. Only these firms can originate agency loans, so borrowers access Fannie and Freddie exclusively through them, never directly.
The rosters are dominated by large commercial mortgage banks — firms like Walker & Dunlop and Berkadia hold seats in both networks — alongside agency-focused platforms at major banks and insurance-affiliated lenders. Membership is hard to win and actively policed: approved lenders must meet capital, underwriting, and servicing standards, and the agencies review their books. For a borrower, that gatekeeping is mostly good news — any approved lender can deliver the same core programs — but it also means the market can feel opaque if you do not already have a relationship.
How does the Fannie Mae DUS model work?
Under the DUS model, Fannie Mae delegates underwriting and servicing to its approved lenders — the lender underwrites the loan, closes it with its own capital, sells it to Fannie Mae, and keeps servicing it, while retaining a meaningful share of the credit risk on every loan through a loss-sharing arrangement.
That risk retention is the defining feature. Because a DUS lender loses real money if the loan defaults, its underwriting incentives are aligned with the agency's, which is what makes delegation workable: most DUS loans do not require Fannie Mae's prior approval on standard terms. For the borrower, delegation means speed and predictability — the lender you are negotiating with genuinely owns the underwriting decision, within the published parameters of the Fannie Mae Multifamily Guide.
How does Freddie Mac Optigo work?
Freddie Mac's Optigo network operates on a prior-approval model: an approved Optigo seller/servicer sources and packages the loan, but Freddie Mac underwrites the credit itself and commits to purchase the loan, which it then typically securitizes through its K-deal program, selling most of the risk to bond investors.
The practical differences from DUS are subtle but real. Freddie's centralized underwriting means the field lender has somewhat less delegated authority, and quotes can involve more back-and-forth with Freddie's regional credit teams. Freddie is also known for program breadth — including its Small Balance Loan (SBL) program for loans of roughly $1 million to $7.5 million, with streamlined documentation aimed at smaller properties. Most sponsors solve for execution by asking a dual-network lender to quote both executions side by side — or by running a process that does it for them.
What terms do agency multifamily loans offer in 2026?
Agency multifamily loans in 2026 typically offer maximum leverage around 80% LTV at a minimum underwritten DSCR near 1.25x, terms from 5 to 30 years with amortization up to 30 years, available interest-only periods, non-recourse structure with standard carve-outs, and features banks rarely match — loan assumption on sale and supplemental loans as the property appreciates.
| Feature | Typical agency execution |
|---|---|
| Maximum leverage | Up to ~80% LTV (tier-dependent) |
| Minimum underwritten DSCR | ~1.25x (tier-dependent) |
| Term | 5-30 years |
| Amortization | Up to 30 years; interest-only available |
| Recourse | Non-recourse with standard carve-outs |
| Prepayment | Yield maintenance or defeasance; step-down options on some executions |
| Assumability | Generally assumable by a qualified buyer |
| Property types | Multifamily only — including affordable, seniors, student, manufactured housing |
The prepayment column deserves attention: agency debt's biggest structural drawback is exit rigidity. Yield maintenance on an early sale can be expensive, which is why sponsors with shorter business plans often pair a bridge loan with an agency takeout instead — a trade-off we cover in bridge vs. Fannie Mae financing.
Do agency loans work for every multifamily deal?
No — agency loans are built for stabilized properties, generally requiring occupancy near 90% with consistent operating history, and they are a poor fit for heavy value-add plans, lease-up deals, or sponsors who expect to sell within a year or two. Deals that miss the box typically use bridge or bank debt first, then refinance into agency once stabilized.
Sponsor qualifications matter too: the agencies look for multifamily experience, net worth and liquidity relative to the loan, and clean background items. A first agency loan is very achievable, but expect the approved lender to underwrite you as carefully as the property, per the documentation standards in the Fannie Mae Guide.
How do you choose an approved lender — and should you get more than one quote?
Choose an approved lender the way you would choose any lender: get multiple quotes. Every DUS and Optigo lender sells the same core programs, but pricing, proceeds, interest-only, waiver appetite, and rate-lock mechanics all vary between shops — and the spread between a strong quote and a mediocre one on the same deal is real money over a 10-year term.
Two structural reasons quotes vary even inside a standardized program: first, DUS lenders retain risk, so each shop's credit culture shows up in its sizing and its willingness to pursue waivers; second, lenders differ in how aggressively they price to win business in a given quarter. A deal that one desk sizes to 70% proceeds, another may push to 75% with a tier adjustment.
This is where a marketplace process earns its keep. YieldStack is a CRE financing marketplace and broker — not a lender and not an agency — that packages your multifamily deal once and matches it against 5,000+ loan programs, including agency executions alongside bank, debt fund, and CMBS alternatives, so you can see whether agency really is your best execution and which terms are competitive. There is no upfront cost to submit.

The bottom line
Agency multifamily loans are originated exclusively by approved lender networks — Fannie Mae's DUS lenders, who underwrite with delegated authority and retained risk, and Freddie Mac's Optigo seller/servicers, who originate for Freddie's centralized underwriting and K-deal securitization. The programs offer leverage, term, and non-recourse structure that banks rarely match on stabilized apartments, but quotes still vary meaningfully between approved lenders — so treat agency debt like any other execution and make lenders compete for the deal. When you are ready, one submission on YieldStack puts agency-eligible programs and their alternatives on the same comparison sheet.
