Capital Structure
Subordinate Debt
How institutional CRE subordinate capital actually works. Mezzanine debt, preferred equity, C-PACE, and seller financing. The structures, enforcement mechanics, and 2026 pricing that determine which layer fits which deal.
Subordinate capital fills the gap between what the senior lender will provide and what the sponsor can (or wants to) fund with equity. The gap is typically 10% to 25% of the capital stack, and the structure chosen to fill it determines the deal's cost of capital, the senior lender's consent requirements, the enforcement timeline if things go wrong, and the tax and balance-sheet treatment for both sides. Mezzanine debt, preferred equity, C-PACE, and seller financing each fill the same slot but with fundamentally different legal structures, collateral mechanisms, and risk-return profiles.
These five articles walk the institutional subordinate capital options one by one, then compare them head to head. Start with mezzanine debt if you are negotiating an intercreditor agreement. Start with preferred equity if the senior lender prohibits subordinate debt. Start with C-PACE if the deal has qualifying energy improvements. Start with seller financing if the transaction involves a willing seller with embedded gain. Each piece carries the structure, a worked 2026 example, and the institutional market data behind the pricing.
