For middle-market commercial real estate borrowers seeking $5M to $15M permanent financing, two competitive bank-style options exist: traditional commercial banks and credit unions. Both fund balance sheet and offer 5 to 10 year fixed-rate or floating structures. The differences show up in pricing on smaller loans (where credit unions often beat banks by 25 to 75 basis points), member-only access requirements, geographic restrictions, and underwriting flexibility. The decision depends on member eligibility, deal size, and existing relationships.

Banks win when the borrower needs scale, prefers a national or regional banking platform, or has no path to credit union membership. Banks have deeper balance sheet capacity for $20M+ deals and broader product menus.
Credit unions win on the smaller end of the middle market when the borrower qualifies for membership and the credit union has appetite for the deal. Credit unions often beat banks by 25 to 75 basis points on $5M to $15M deals due to their cooperative ownership structure and lower cost of funds.
Start with membership eligibility. If the borrower qualifies for a strong credit union (often through state of residence, employer affiliation, or trade association membership), credit union pricing becomes available. If not, banks are the only path.
Run the rate spread math. Credit unions on $5M to $15M deals frequently price 25 to 75 basis points inside comparable bank balance sheet quotes. On a $10M loan over 7 years, that 50 basis point spread is approximately $250K of saved interest. The savings is meaningful for relationship-eligible borrowers.
Evaluate balance sheet capacity. Credit unions are smaller institutions and typically prefer loans under $20M. Larger deals push toward banks where balance sheet capacity is deeper. Some larger credit unions handle $20M to $50M but the bench narrows quickly.
Consider service breadth. Banks offer broader products: capital markets, treasury management, international banking, complex syndications. Credit unions excel at member-focused depository, simple commercial loans, and personal banking integration. Match the lender to the borrower's broader banking needs.
On an $8.4M industrial property refinance in a Pacific Northwest market, the sponsor (a local family business with depository relationships at both a regional bank and a state-chartered credit union) ran competing quotes. The regional bank quoted at 7.45 percent fixed 5-year with 25-year amortization at 70 percent LTV with full recourse. The credit union quoted at 7.05 percent fixed 5-year with 25-year amortization at 70 percent LTV with full recourse, plus an existing depository relationship that delivered a 0.05 percent rate buy-down. The 45 basis point spread translated to approximately $190K of saved interest over the 5-year fixed term. The sponsor took the credit union execution.

On $5M to $15M middle-market deals, credit unions are systematically underpriced versus banks. The membership requirement is real, but for borrowers who qualify, the rate compression is meaningful and worth running through the competitive process every time.
