A client I work with recently refinanced a 120-unit apartment complex in suburban Phoenix — and his first question wasn’t “what rate can I get?” It was “is this a CMBS deal or a conventional one?” That’s the right question. The answer shapes your interest rate, your prepayment flexibility, and your servicer relationship for the next seven to ten years.
CMBS loans are one of the most powerful tools in commercial real estate financing — and one of the least understood. Here’s what the CMBS loan requirements actually look like in 2026, how the loan structure works, and how to decide if CMBS is right for your deal.
What you’ll learn:
- What CMBS loans are and how they’re securitized
- Loan requirements: DSCR, LTV, debt yield, net worth, liquidity
- Prepayment mechanics (defeasance vs. yield maintenance)
- CMBS vs. conventional commercial mortgages: key differences
- When CMBS makes sense — and when to look elsewhere
What Is a CMBS Loan?
A CMBS loan is a commercial real estate mortgage that gets pooled with other loans, packaged into a trust, and sold to bond investors as securities. Instead of holding the loan on a bank’s balance sheet, the originating lender sells it into the secondary market — which frees up capital for new originations and gives institutional investors access to commercial mortgage cash flows.
This structure has real consequences for borrowers. Once your loan sells into a securitized pool, the originator is gone. The loan is serviced by a master servicer that collects payments and handles routine matters. If you ever need a modification, extension, or covenant waiver, that decision falls to a special servicer, which operates under strict pooling and servicing agreement (PSA) rules. The flexibility you might get from a relationship banker is largely off the table.
CMBS comes in two primary formats:
- Conduit loans: Multiple loans are pooled together, diversifying exposure across property types, geographies, and borrowers. Individual loan sizes typically run $5M to $100M.
- Single-asset, single-borrower (SASB): One loan on one asset or portfolio. Used for larger, high-quality assets ($50M+) where the property warrants its own securitization.
How CMBS Loans Are Structured
CMBS loans are fixed-rate, non-recourse, and amortized over 25–30 years — though the loan term is typically 5, 7, or 10 years. At the end of the term, the remaining balance comes due as a balloon payment. You either refinance, sell, or pay it off.
Non-recourse is the headline feature: the lender’s recourse in default is limited to the property. They can’t pursue your other assets (subject to standard “bad boy” carve-outs for fraud, bankruptcy filing, and other prohibited acts). For investors who want to ring-fence personal liability on a specific asset, this matters.
Fixed rate is the other major feature. CMBS pricing is based on spreads over the corresponding Treasury swap rate. In mid-2026, that translates to roughly 5.75–7.50% depending on property type and LTV.
One thing borrowers often overlook: interest-only periods. Many CMBS deals are structured with IO for part or all of the term. IO reduces annual debt service, which improves DSCR and can allow higher loan proceeds — but your principal balance doesn’t go down. Both facts matter at refinance or sale.
CMBS Loan Requirements: What Lenders Look For
Conduit underwriting is more formulaic than bank lending. Here’s what matters in 2026:
Minimum loan size: $5 million is the practical floor. Some lenders will consider $2–3M on high-quality assets in primary markets, but pricing is worse and the pool of willing lenders shrinks. If your deal is under $5M, you’re looking at a small balance commercial real estate loan through a bank, credit union, or agency execution.
Debt service coverage ratio (DSCR): Minimum 1.20x–1.25x on stabilized, in-place cash flow. Lenders underwrite to actual net operating income — not projected rents. Vacancy allowance, credit loss, and management fees all get applied before DSCR is calculated.
Loan-to-value (LTV): 65–75% is standard. Some lenders go to 80% on institutional-quality assets with strong debt yield. Most conduit programs use 65–70% as the primary underwriting constraint.
Debt yield: This metric matters at least as much as LTV. Debt yield = net operating income ÷ loan amount. Most conduit lenders want 10%+ debt yield; some go to 8–9% for high-quality properties. Debt yield acts as a floor independent of appraised value — so a high-cap-rate asset can sometimes achieve better leverage than a compressed-cap property worth more on paper.
Borrower net worth: At least 25% of the total loan amount. A $20M loan requires $5M+ in documented net worth.
Liquidity: Typically 5–10% of the loan amount in accessible liquid assets at close.
Property type: CMBS lenders finance most income-producing commercial property types — multifamily (5+ units), office, retail, industrial, mixed-use, hospitality, and self-storage. NNN net-lease properties are frequent CMBS candidates given their stable, predictable cash flows. The property must be stabilized. Ground-up construction and transitional assets generally don’t qualify.
CMBS Prepayment: The Part Most Borrowers Don’t See Coming
Prepayment restrictions are the most consequential feature most borrowers don’t fully think through until it’s time to sell or refinance.
Year 1–2: Lockout. No prepayment permitted under any circumstances.
After lockout — defeasance or yield maintenance: These are the two dominant mechanisms, and both are expensive.
- Defeasance: You replace the loan with a portfolio of U.S. Treasury securities that replicates the loan’s cash flows. The cost is driven by the rate differential between your loan and current Treasuries. In a falling-rate environment, this can add 5–10%+ of the loan balance in prepayment costs.
- Yield maintenance: You pay the lender the present value of remaining interest payments, discounted at current Treasury rates. The dollar impact is similar to defeasance in practice.
I’ve seen borrowers walk away from otherwise-profitable sales because the defeasance cost made the math work against them. CMBS is a commitment. If there’s any chance you’ll sell or refinance within five years, model the prepayment cost before signing.

From a recent deal: I recently worked on a CMBS conduit placement for a grocer-anchored retail strip center in the Atlanta metro — 64,000 square feet, long-term tenants, stable rents, low vacancy. The borrower’s bank had quoted the deal themselves, but their pricing was 75bps higher, their LTV ceiling was lower, and they wanted full recourse. The CMBS execution came in at 67% LTV, non-recourse, with a 10-year fixed term at 6.35%. DSCR was 1.31x on stabilized rents. Defeasance was the prepayment mechanism, and the borrower understood he was in this for the long haul — which matched his plan. The savings over the term more than offset the reduced flexibility.
CMBS vs. Conventional Commercial Mortgages
Neither is universally better — they solve different problems. Here’s how the primary differences play out in practice:
| Feature | CMBS Conduit | Conventional Commercial |
|---|---|---|
| Rate | Generally lower (Treasury spread-based) | Higher (bank cost of funds) |
| LTV | 65–75% | 60–70% typical |
| Recourse | Non-recourse (with bad-boy carve-outs) | Usually full recourse |
| Flexibility | Low — standardized docs, limited mods | Higher — bank can waive or modify |
| Prepayment | Lockout + defeasance or yield maintenance | Step-down or open after a period |
| Minimum size | $5M+ | No hard floor (varies by lender) |
| IO availability | Common | Less common |
| Assumability | Yes — fully assumable | Typically not |
Assumability is worth calling out specifically. A CMBS loan can transfer to a buyer at the original terms when you sell — which can be a real selling point if rates have risen since origination. A buyer assuming your 6.35% CMBS loan in a 7.5% rate environment is getting below-market financing built into the purchase price.
For stabilized income-producing properties and larger commercial assets, CMBS often beats conventional on rate, LTV, and recourse. For multifamily refinancing under $5M, or for situations requiring flexibility to modify or exit early, conventional lending or agency execution is typically the better fit.
CMBS Loan Rates in 2026
As of mid-2026, CMBS conduit pricing for stabilized assets runs approximately:
- Multifamily (5+): 5.75–6.50%
- Industrial/warehouse: 5.75–6.25%
- Self-storage: 6.00–6.75%
- Retail (stabilized): 6.25–7.00%
- Office: 6.50–7.50% (elevated spreads due to occupancy uncertainty)
- Hospitality: 6.50–7.50%
These are spread-over-Treasury executions. The 10-year swap has been trading near 4.25–4.50% in August 2026, with conduit spreads ranging 150–300bps depending on property type, LTV, and loan size. SASB deals on larger single assets can price inside conduit on a spread basis.
The rate context matters: according to Scotsman Guide, U.S. private-label CMBS issuance reached $76.2 billion through the first seven months of 2026 — on pace for what KBRA projects could be a post-global financial crisis record of $183 billion for the full year. Lender appetite is real, and competitive spread execution is benefiting borrowers with clean, stabilized assets.
When CMBS Makes Sense — and When It Doesn’t
CMBS tends to win when:
- You’re financing a stabilized, cash-flowing commercial property over $5M
- You want a long-term fixed rate with non-recourse structure
- The property is in a secondary or tertiary market where bank appetite is thin
- You’re planning to hold through the full term — 7 or 10 years
- Assumability adds value to your eventual exit strategy
- The property generates strong debt yield (10%+)
CMBS is usually the wrong tool when:
- The property needs repositioning or renovation — CMBS requires stabilized income. For value-add commercial real estate financing, a bridge loan is the right structure first.
- You expect to sell or refinance within five years — prepayment costs will erode returns
- You need ongoing servicer flexibility: lease approvals, partial releases, future advances
- The property has high vacancy, short lease terms, or significant tenant credit exposure
- Deal size is under $5M — small balance or bank execution is usually more appropriate
One additional consideration in 2026: approximately $76.6 billion in CMBS loans face hard maturities this year, per CRE Daily, many from 2016-era originations on office and retail assets where values have since compressed. If you have a maturing CMBS loan, start refinancing conversations 12–18 months early — not 60 days out. The conduit market is open and active, but the process has a timeline that can’t be rushed.

Frequently Asked Questions
What is the minimum loan amount for a CMBS loan?
Most conduit programs start at $5 million. A handful of lenders will consider $2–3M on high-quality assets in primary markets, but pricing worsens and lender selection shrinks considerably. Below $5M, small balance commercial, bank, or agency execution is typically more appropriate.
Are CMBS loans non-recourse?
Yes — CMBS loans are non-recourse, meaning the lender’s remedy in default is the property itself. Standard “bad boy” carve-outs apply: fraud, misrepresentation, voluntary bankruptcy filing, and other prohibited acts can trigger personal liability even under a non-recourse structure.
What is defeasance on a CMBS loan?
Defeasance is the primary prepayment mechanism after the lockout period expires. To pay off or refinance early, the borrower replaces the original collateral with a portfolio of U.S. Treasury securities that replicates the loan’s remaining cash flows. The cost is driven by the spread between the loan rate and current Treasury yields — which makes it particularly expensive in falling-rate environments.
What property types qualify for CMBS financing?
CMBS lenders finance most income-producing commercial property types: multifamily (5+ units), retail, office, industrial, mixed-use, hospitality, NNN net-lease, and self-storage. The property must be stabilized and generating in-place cash flow. Ground-up construction and transitional value-add properties do not qualify.
How long does a CMBS loan take to close?
CMBS conduit loans typically take 45–90 days from term sheet to close. The process involves third-party reports (appraisal, environmental, property condition assessment), legal coordination, and final trust approval. Start the process early — conduit timelines aren’t compressible the way bank deals sometimes are.
