Fannie Mae DUS and Freddie Mac Optigo are the two government-sponsored enterprise (GSE) multifamily programs that finance roughly 40 to 60 percent of all U.S. apartment debt in any given year. Both deliver non-recourse, long-term fixed-rate financing for stabilized multifamily, typically at 65 to 80 percent LTV with 10-year terms. The difference between them shows up in pricing on a deal-by-deal basis, prepayment structure flexibility, small-balance execution speed, and how each program treats workforce and affordable rent commitments. Choosing correctly can shift your all-in rate by 15 to 30 basis points and your prepayment penalty by hundreds of thousands of dollars over the life of the loan.

Fannie Mae DUS tends to be the right choice when you have a lender relationship that maps to a DUS shop and your deal benefits from DUS-specific structuring options. The DUS program has a deeper bench of life-of-loan supplemental capacity, a slightly more flexible interest-only window in many quotes, and a more straightforward path on tertiary markets and on certain large MHC and student housing assets.
Freddie Mac Optigo often wins on small-balance multifamily under $7.5M and on Targeted Affordable Housing executions with bond credit enhancement. Optigo SBL has been a faster-to-close program for years, with a streamlined underwriting box that benefits sponsors who need certainty of execution under 45 days.
Run both programs on every conventional multifamily refinance or acquisition above $5M. There is no premium for asking, and the spread between agencies on any given day is unpredictable. The lender that wins is rarely obvious before quotes come in. The single biggest mistake we see borrowers make is loyalty to one DUS lender or one Optigo Seller-Servicer based on a prior relationship. The agencies are competing for production every quarter; the spread shifts.
On small balance ($1M to $9M), the speed difference matters more than the rate difference for most acquisitions. Optigo SBL closes 30 to 45 days from application, DUS Small closes 35 to 50. If your purchase contract has a 45-day financing contingency, that 1 to 2 week buffer is the difference between a clean close and an extension fee.
On affordable and mission-driven deals, the answer is structural, not pricing. Fannie's Mission-Driven cap exclusion versus Freddie's TAH bond credit enhancement framework lead to materially different capital stacks. A 4 percent LIHTC bond deal generally goes Optigo TAH; a workforce 80 to 120 percent AMI without LIHTC often goes Fannie Mission-Driven.
On structure and prepayment, the right answer depends on your hold horizon. If you plan to refinance or sell at year 5 of a 10-year fixed, the yield maintenance penalty under either agency can be punishing in a falling-rate environment. Defeasance under Optigo lets you sell the loan to a third-party defeasance buyer without writing the full prepay check. If you are positioning for a sale at year 5, ask the broker to model both YM and defeasance side by side.
On a 124-unit Class B multifamily refinance in a Tier 2 Sun Belt MSA with an institutional sponsor and a 1.32x as-is DSCR, we ran both DUS and Optigo simultaneously through three lenders on each side. The winning DUS quote came back at a 5.78 percent fixed 10-year with two years of interest-only, full term yield maintenance. The winning Optigo SBL quote came back at 5.71 percent with one year of interest-only and a defeasance prepayment option. The 7 basis point coupon advantage on Optigo translated to roughly $42K of interest savings over the term, but the sponsor planned to sell at year 6 and ultimately took DUS because the YM exit math under projected forward rates was more favorable than defeasance economics. The takeaway: rate is one input, prepay structure is another, and you do not know until you run both.

If you are not running Fannie and Freddie simultaneously on every conventional multifamily deal, you are leaving money on the table. The agencies are competing every week for production, and the lender that wins on Tuesday may not be the lender that wins on Friday.
