CMBS vs Bank Permanent for Middle-Market Commercial Real Estate
By Trevor Damyan, Commercial Mortgage Broker at Commercial Lending Solutions
For middle-market commercial real estate between $5M and $50M, the most consequential permanent financing decision is whether to go CMBS conduit or bank balance-sheet. Both products deliver long-term fixed-rate debt on stabilized assets, but they are structurally different instruments serving different sponsor priorities. CMBS wins on non-recourse leverage, longer interest-only periods, 30-year amortization, and the ability to assume the loan at sale. Bank permanent wins on rate for strong sponsors, speed to close, covenant flexibility, and relationship-driven underwriting on assets that do not fit a conduit box. The rate spread between the two is often 25 to 75 basis points, but the more important variables are recourse appetite, hold period, asset class, and exit strategy. Getting this decision wrong costs more than the coupon difference.

When CMBS Conduit Loan Is the Right Call
CMBS conduit is the right tool when the sponsor's primary objective is maximizing non-recourse leverage on a long hold, when the asset class or market does not fit a local bank's appetite, or when the borrower needs the loan to be assumable at a future sale. Conduit underwriting is standardized and scalable, which means hospitality, STNL retail, and large mixed-use assets that fall outside a regional bank's comfort zone routinely clear the conduit credit box.
- Sponsor requires non-recourse at closing and cannot or will not provide a full personal guaranty to a bank
- Hospitality asset such as a select-service or full-service hotel where conduit dominates the permanent market and bank appetite is limited
- Single-tenant net lease retail where CMBS sizing to 70 to 75 percent LTV exceeds what a bank will underwrite on the same tenancy
- Long hold strategy of 7 to 10 years where 30-year amortization and a long interest-only period improve cash-on-cash returns
- Acquisition where the seller has an existing assumable CMBS loan at a below-market rate, allowing the buyer to step into favorable debt
- Portfolio or large mixed-use asset where aggregate loan size exceeds a single bank's legal lending limit or concentration appetite
When Bank Permanent Loan Is the Right Call
Bank balance-sheet permanent debt wins when the sponsor has strong relationships, creditworthy recourse capacity, and a 5 to 7 year hold horizon where the tighter rate more than offsets CMBS structural advantages. Banks also dominate smaller industrial, suburban office, and owner-occupied commercial properties where conduit underwriting is either unavailable or uncompetitive. The ability to negotiate covenant packages, partial release provisions, and construction-to-perm structures gives banks real flexibility that CMBS cannot replicate.
- Creditworthy sponsor with strong global cash flow who can trade recourse for a 25 to 75 basis point rate reduction versus the equivalent CMBS quote
- Small to mid-size industrial or suburban office assets where local bank underwriters know the submarket and can stretch on occupancy or lease term
- Intermediate hold horizon of 3 to 7 years where a bank step-down prepay is meaningfully cheaper than CMBS yield maintenance or defeasance at exit
- Construction-to-permanent financing where the bank retains the loan from construction through stabilization without requiring a separate takeout
- Asset requiring partial release or substitution provisions, such as a portfolio with individual property dispositions, that CMBS pooling prohibits
- Owner-occupied or partially owner-occupied commercial property eligible for SBA 504 or conventional owner-user bank financing at favorable terms
How to Choose Between CMBS Conduit Loan and Bank Permanent Loan
The first question to answer is recourse. If the sponsor cannot or will not sign a full personal guaranty, the decision is largely made: CMBS non-recourse is the standard product, and most banks require recourse except for the largest and most institutionally capitalized borrowers. If the sponsor is willing to provide recourse and has strong global cash flow, the rate advantage of bank debt typically ranges from 25 to 75 basis points, which on a $15M loan at 7 years compounds to a meaningful dollar difference. Model the all-in cost of each structure before letting a single factor drive the decision.
The second variable is hold period and exit strategy. CMBS is purpose-built for 7 to 10 year holds: yield maintenance or defeasance penalties are punishing if you exit in years 2 to 5, but the assumability feature creates real value if a buyer at year 7 can step into your below-market fixed rate without triggering a prepay. Bank loans with step-down prepay schedules are far more forgiving for sponsors who anticipate selling or refinancing within 5 years. A 5,4,3,2,1 step-down on a bank loan costs 1 percent at year 5 exit versus yield maintenance on CMBS that could exceed 5 to 8 percent of the loan balance in a falling-rate scenario.
Asset class and market substantially influence which product is available and competitive. CMBS conduit originators are most active in hospitality, anchored retail, STNL net lease, self-storage, and larger mixed-use. Regional and community banks are most active in industrial, smaller office, owner-occupied commercial, and suburban retail. Banks also have an advantage in secondary and tertiary markets where local underwriters have genuine submarket knowledge. A bank that has financed 20 industrial properties in a mid-size market over 10 years will underwrite sponsor and asset risk differently than a conduit lender applying standardized national criteria.
The tranching mechanics of CMBS deserve specific attention. In a conduit securitization, the loan is pooled with other commercial mortgages and sold to investors in rated tranches. The B-piece buyer, who absorbs the first-loss position in the pool, has veto power over individual loans and sets the practical credit floor. This means the conduit lender's initial term sheet is subject to B-piece review, and deals that look clean at origination can get recut or repriced during securitization. Bank balance-sheet loans have no such re-trade risk because the lender holds the loan and approval is final at commitment. For deals with credit nuance or unusual collateral, the certainty of a bank execution often justifies the structural trade-offs.
A Real Decision in Action
On a 187,000 square foot anchored retail center in a major Sun Belt market, stabilized at 94 percent occupancy with a national grocer anchor and 12 years of lease term remaining, we ran both CMBS conduit and bank balance-sheet simultaneously. The best conduit quote came in at 6.45 percent fixed for 10 years, non-recourse, 25-year amortization, 2 years of interest-only, yield maintenance prepay. The best bank quote came in at 6.10 percent fixed for 7 years, full recourse to the operating entity and key principals, 25-year amortization, step-down prepay at 4,3,2,1. The sponsor had recourse capacity and planned to sell at year 6 after completing a lease-up of two vacant junior anchor spaces. The 35 basis point rate savings on the bank loan translated to approximately $330,000 in interest over 7 years, and the step-down prepay at year 6 was one percent versus an estimated yield maintenance penalty of $1.1M on the CMBS loan under prevailing rate projections. The bank loan won on total cost of capital by a substantial margin. The asset class and exit horizon aligned perfectly with bank execution.

Non-recourse is not free. CMBS charges you for it in spread, in prepay rigidity, and in B-piece re-trade risk. Every sponsor should know their recourse capacity and price it before defaulting to conduit. The sponsors who run both products on every deal consistently find 30 to 70 basis points of savings they would have left on the table by going straight to CMBS.
