CMBS vs Agency (Fannie/Freddie): Which Multifamily Loan Wins in 2026?

For stabilized, conventional apartments, agency debt (Fannie Mae and Freddie Mac) usually wins on rate, leverage, and especially affordable or green incentives, it is purpose-built for multifamily. CMBS conduit wins when the asset is outside the agency box: mixed-use with significant commercial income, smaller or tertiary markets, sub-types agencies decline, or borrowers who want one lender for a multi-property portfolio. Both are non-recourse and the choice turns on asset fit, leverage, and prepayment rather than headline rate alone.

On a clean, stabilized, conventional apartment, agency typically prices at or inside CMBS conduit, and agency affordable and green programs can price meaningfully tighter. CMBS can occasionally match or beat agency on a strong, large, low-leverage asset when conduit spreads are tight, but agency's mission-driven pricing on workforce and affordable housing is hard to beat. Rate is only part of the cost: agency prepayment and CMBS defeasance both carry real exit cost, so compare all-in cost over your actual hold.

Both top out around a 60–65% gold-standard LTV on most stabilized commercial-style underwriting, though agency multifamily can reach up to roughly 70–75% on conventional apartments that clear the DSCR and debt-yield tests, with affordable deals sometimes higher. CMBS multifamily generally sizes to the 60–65% range governed by a minimum debt yield. Neither offers 100% financing, the sponsor still contributes meaningful equity. Final proceeds are set by DSCR and debt yield, not the LTV cap alone.

Both are typically non-recourse, subject to standard bad-boy carve-out guaranties (fraud, misappropriation, bankruptcy, waste). That parity is one reason the choice comes down to asset fit, leverage, prepayment, and servicing rather than recourse. Agency loans are originated by approved DUS and Optigo lenders and sold to Fannie Mae or Freddie Mac; CMBS conduit loans are pooled and securitized. In both cases the borrower deals with a servicer post-close rather than the original lender.

CMBS conduit loans are almost always locked with defeasance, replacing the property's cash flow with a portfolio of government securities to release the lien, which is operationally complex and can be costly when rates have fallen. Agency loans more often use yield maintenance, and many programs offer step-down prepayment options that are simpler and cheaper to exit, especially Freddie Mac small-balance and certain Fannie programs. If you expect to sell or refinance before maturity, agency's prepayment flexibility is frequently the deciding factor.

When the asset or borrower sits outside the agency box: meaningful commercial or retail income in a mixed-use building, markets or sub-types agencies underweight, a borrower who wants a single lender for a portfolio spanning multifamily plus other commercial asset classes, or a deal that needs to close on a story the agencies will not credit. CMBS underwrites the asset's cash flow with more flexibility on these edge cases, at the cost of defeasance-based prepayment and securitized servicing. For a plain-vanilla stabilized apartment, agency usually still wins.
