If you are financing commercial real estate and the deal is too large for a local bank or too complex for an SBA loan, you are likely looking at two primary options: CMBS (Commercial Mortgage-Backed Securities) or agency debt (Fannie Mae / Freddie Mac). These are not interchangeable products. They serve different asset types, different borrower profiles, and different return strategies. Choosing the wrong one costs you basis points, flexibility, or both. This guide breaks down when each makes sense, how pricing compares in 2026, and the structural differences that determine which is right for your deal.
1What CMBS and Agency Debt Actually Are
Both CMBS and agency debt are securitized lending products — meaning the loans are originated by lenders and then packaged into securities that are sold to investors. This securitization model is what allows these lenders to offer non-recourse financing (no personal guarantee) at competitive rates for large commercial real estate deals. But the mechanics, asset types, and lender structures are fundamentally different.
CMBS (Commercial Mortgage-Backed Securities)
CMBS loans are originated by conduit lenders (banks, specialty finance companies) and pooled into trusts that issue bonds backed by the underlying mortgages. The loans are then serviced by a master servicer, with a special servicer handling defaults and workouts. CMBS is available for virtually all commercial property types: office, retail, industrial, mixed-use, hospitality, self-storage, and — in some cases — multifamily.
Agency Debt (Fannie Mae DUS / Freddie Mac Optigo)
Agency debt is originated by approved lenders (Delegated Underwriting and Servicing lenders for Fannie Mae, Optigo lenders for Freddie Mac) and purchased or guaranteed by the government-sponsored enterprises. Because Fannie and Freddie carry an implicit government guarantee, agency debt trades at tighter spreads than CMBS — which translates to lower rates for borrowers. However, agency debt is exclusively for multifamily properties (5+ units). If your asset is not multifamily, agency is not an option.
The Fundamental Distinction
CMBS is asset-type agnostic — it finances any stabilized commercial property. Agency debt is multifamily-only. If your deal is a multifamily asset, you have both options. If it is anything else, CMBS is your securitized lending path. This distinction alone determines the starting point for most borrowers.
2Rate Comparison: CMBS vs Agency in 2026
Pricing is the most common question borrowers ask, and the answer in 2026 reflects the current interest rate environment and risk premiums for each product type. The following ranges represent stabilized assets with institutional-quality borrowers — distressed or transitional assets will price wider.
| Metric | CMBS | Agency (Fannie/Freddie) |
|---|---|---|
| Interest Rate Range | 6.25–9.50% | 5.00–7.00% |
| Rate Type | Fixed (5, 7, or 10 year) | Fixed (5, 7, 10, 12, or 15 year) |
| Spread Over Benchmark | T+180–350 bps | T+140–250 bps |
| Rate Lock Timing | At closing (rate risk until then) | Early rate lock available (30–60 days pre-close) |
| Maximum LTV | 65–75% | 75–80% |
| Minimum DSCR | 1.25x | 1.20–1.25x |
| Amortization | 25–30 years | 30 years standard |
| Recourse | Non-recourse (standard carve-outs) | Non-recourse (standard carve-outs) |
| Minimum Deal Size | $2M–$5M | $1M (Freddie Small Balance) |
| Prepayment Structure | Defeasance or yield maintenance | Yield maintenance, defeasance, or declining prepayment |
| Asset Types | Office, retail, industrial, hospitality, mixed-use, multifamily | Multifamily ONLY (5+ units) |
The rate advantage of agency debt over CMBS is typically 75–200 basis points for comparable multifamily deals. Over a 10-year term on a $10M loan, that spread translates to $750K–$2M in total interest savings. This is why, for multifamily assets, agency debt is almost always the preferred path unless deal-specific factors push you toward CMBS.
3When to Use CMBS
CMBS is the right choice when your asset does not qualify for agency debt, when you need higher leverage than a bank will provide, or when you want non-recourse financing on a non-multifamily asset. Specific scenarios where CMBS is the strategic choice:
Non-multifamily commercial properties
Office buildings, retail centers, industrial properties, hotels, self-storage facilities, and mixed-use assets. Agency debt is not available for these property types — CMBS is the primary securitized lending channel.
Stabilized assets where you want non-recourse and maximum leverage
CMBS provides up to 75% LTV on a non-recourse basis for stabilized commercial properties. A local bank might offer 65% LTV with a personal guarantee. CMBS gives you higher leverage without the recourse — a significant advantage for portfolio borrowers.
Properties in secondary or tertiary markets
CMBS conduit lenders are generally more willing to finance properties in smaller markets than agency lenders, who tend to prefer primary and strong secondary MSAs for multifamily deals. If your asset is in a smaller market, CMBS may be the more accessible channel.
Borrowers who want a transactional relationship
CMBS is a capital markets execution — the loan is originated and sold. There is no ongoing banking relationship, no deposit requirements, and no cross-sell expectations. You get the capital and move on. This suits investors who operate across multiple lender relationships.
Hospitality and specialty assets
Hotels, resorts, and specialty-use properties (medical office, data centers, etc.) are financed almost exclusively through CMBS at the securitized level. CMBS conduits have underwriting expertise and historical performance data for these asset types that agency lenders do not.

4When to Use Agency Debt
Agency debt is the right choice when your asset is multifamily (5+ units), stabilized or near-stabilized, and located in a market with strong demographic fundamentals. The rate advantage, leverage advantage, and structural flexibility of agency debt make it the preferred path for most multifamily acquisitions and refinances.
Stabilized multifamily acquisitions
Agency debt offers the lowest rates and highest leverage available for stabilized multifamily properties. A stabilized 100-unit apartment complex with 90%+ occupancy and a 1.25x DSCR is the ideal agency deal — 75–80% LTV, non-recourse, 30-year amortization, and rates 100–200 bps below CMBS.
Multifamily refinances and recapitalizations
If you own a multifamily asset financed with a bridge loan or bank debt, agency is the preferred permanent financing exit. The rate compression from bridge (8–12%) to agency (5–7%) is the entire value creation strategy for many multifamily operators.
Affordable and workforce housing
Both Fannie Mae and Freddie Mac have dedicated affordable housing programs with enhanced terms — higher LTV (up to 85% in some programs), reduced fees, and preferred pricing for properties that serve low- and moderate-income tenants. If your multifamily asset serves this population, the agency programs are purpose-built for your deal.
Small balance multifamily ($1M–$7.5M)
Freddie Mac's Small Balance Loan program and Fannie Mae's Small Loan program provide agency-level terms for smaller multifamily properties that would be below the minimum deal size for CMBS. This is a significant advantage for investors acquiring 20–80 unit properties in smaller markets.
5Prepayment Structures: The Hidden Cost That Changes the Math
The interest rate is the number everyone focuses on. The prepayment structure is the number that actually determines your flexibility — and potentially your exit cost. Both CMBS and agency loans carry prepayment provisions, but they are structured differently and the financial impact can be enormous.
CMBS Prepayment: Defeasance and Yield Maintenance
Most CMBS loans use either defeasance or yield maintenance as the prepayment mechanism. Defeasance requires you to replace the loan's cash flows with a portfolio of U.S. Treasury securities — essentially substituting government bonds for your property as the collateral backing the securitized trust. The cost of defeasance depends on the current Treasury yield curve relative to your loan rate. In a falling rate environment, defeasance is expensive. In a rising rate environment, it can be close to zero.
Yield maintenance requires you to pay the lender the present value of the remaining interest payments they would have received — essentially making the lender whole on the deal. Yield maintenance is typically more expensive than defeasance in a declining rate environment.
Agency Prepayment: More Flexibility Available
Agency loans offer more prepayment flexibility than CMBS. Fannie Mae and Freddie Mac both offer yield maintenance and defeasance options, but they also offer declining prepayment schedules (e.g., 5-4-3-2-1% of the outstanding balance) on some programs. Additionally, agency lenders can offer prepayment penalties that decline to zero in the final 90 days of the loan term — a feature not typically available in CMBS.
The Exit Strategy Test
Before you commit to any CMBS or agency loan, model your exit scenario. If you plan to sell or refinance in 3–5 years, a 10-year loan with defeasance could cost you hundreds of thousands of dollars to exit early. A 5-year loan with a declining prepayment schedule may cost more in rate but save you significantly on the back end. The right loan term is the one that matches your hold period — not the one with the lowest rate.
6Bridge-to-Permanent: When Neither CMBS Nor Agency Fits Today
Both CMBS and agency debt require stabilized assets — meaning high occupancy, consistent cash flow, and a property condition that does not require significant capital expenditure. If your property is not yet stabilized (value-add multifamily, lease-up office, recently renovated retail), you need a bridge loan first and a plan to refinance into CMBS or agency once the asset is performing.
Bridge loans for commercial real estate typically carry rates of 7–12%, terms of 12–36 months, and interest-only payment structures. The purpose is to provide capital for acquisition, renovation, and lease-up — then exit into permanent financing (CMBS or agency) at substantially lower rates once the asset is stabilized.

The Bottom Line
CMBS and agency debt are both powerful tools for financing commercial real estate — but they are not interchangeable. Agency debt is the preferred path for stabilized multifamily, offering the lowest rates, highest leverage, and most flexible prepayment structures. CMBS is the path for non-multifamily commercial assets, providing non-recourse financing at scale for office, retail, industrial, hospitality, and mixed-use properties. The borrowers who get the best execution are the ones who understand both channels, model the full cost of capital including prepayment, and work with advisors who can access both markets simultaneously.
