Agency multifamily debt and CMBS conduit debt both target stabilized rental housing at 60 to 75 percent LTV on 10-year non-recourse terms. They are not interchangeable. Agency wins on coupon for most market-rate deals because the GSEs have a regulatory mandate to lend on multifamily and price accordingly. CMBS wins on a narrower band of deals where deal characteristics fall outside the agency box, where the sponsor needs a structure the agencies will not write, or where the loan is part of a larger pooled execution. Picking the wrong program can cost 30 to 75 basis points in rate or eliminate optionality at exit.

Agency wins on the bulk of stabilized market-rate multifamily because the GSEs price competitively, lever to 80 percent, and have a deep ecosystem of DUS and Optigo lenders competing on every deal. For sponsors planning to hold 7 to 10 years and willing to play in the conforming box, agency is the default choice on price.
CMBS wins on stabilized multifamily when the deal cannot fit cleanly inside the agency box. The CMBS execution layer is more flexible on property condition, sponsor resume, occupancy ramps, and structural quirks, at the cost of a higher coupon and less servicing flexibility post-close.
Start with the agency. If the deal fits inside DUS or Optigo, the agencies will out-price CMBS by 30 to 75 basis points nine times out of ten. The exception is when the property has too much commercial NOI, the sponsor has insufficient liquidity, or the market is too thin for agency Seller-Servicers to compete aggressively. In those cases, CMBS may be the only execution.
Evaluate prepay flexibility. Yield maintenance under Fannie or YM under Freddie can be punishing in a falling-rate environment, but defeasance under Freddie or under CMBS allows the loan to be sold to a defeasance buyer at exit. If the sponsor has a high probability of selling before maturity, defeasance optionality matters more than the headline rate.
Run the math on full-term interest-only. CMBS will sometimes write full-term IO at 60 to 65 percent LTV on stabilized multifamily where the agencies will only quote 3 to 5 years of IO. The IO benefit is meaningful for sponsors looking to maximize cash distributions during the hold period.
On loans above $50M, both agencies and CMBS conduits will compete, but CMBS pool dynamics can sometimes price tighter than the GSEs because the loan becomes a meaningful pool asset. On these large deals, you should run both and let the lenders fight for it.
On a $28M Class B suburban multifamily refinance with a 22 percent ground-floor retail component (a stabilized neighborhood center attached to the apartments), Fannie and Freddie both passed because the commercial NOI exceeded the multifamily cutoff. CMBS quoted at 6.42 percent on a 10-year fixed, 30-year amortization, with 5 years of interest-only, 65 percent LTV, full defeasance prepay. The sponsor took the CMBS execution because no agency lender would quote, and the CMBS structure preserved the optionality of a sale at year 5 through defeasance. Two years later the sponsor sold and defeased the loan in 30 days at a defeasance cost roughly equal to 18 months of yield maintenance, validating the prepay choice.

Agency wins on stabilized market-rate multifamily nine times out of ten. The other one is the CMBS deal, and it is almost always because the property has too much commercial NOI, a thin market, or a sponsor story the agencies will not underwrite.
