Commercial Real Estate Mezzanine Financing

What mezzanine debt does in the capital stack

Mezzanine financing occupies the space between senior debt and sponsor equity. A senior lender may advance 60% to 65% of cost on a transaction the sponsor has underwritten at 85% total leverage. Mezzanine capital funds that gap, sitting junior to the senior loan in payment priority and typically secured by a pledge of the equity interests in the property-owning entity rather than by a mortgage on the real estate itself.

That security structure is what makes mezzanine practical. Because the collateral is the ownership interest rather than the asset, the senior mortgage is not disturbed and the senior lender’s lien position is unaffected. Remedies run through the pledged equity, which is also why the intercreditor agreement — governing standstill periods, cure rights, transfer restrictions and the conditions under which the mezzanine lender may act — is negotiated as carefully as the loan itself.

For a sponsor, the comparison is usually mezzanine debt against joint-venture equity. Mezzanine carries a fixed cost, a defined maturity and no dilution of upside; JV equity shares the profit but demands no scheduled payment. Where the business plan is credible and the cash flow supports the combined debt service, mezzanine preserves the sponsor’s economics.

• Junior to the senior loan in payment priority and remedy
• Secured by a pledge of equity interests, leaving the senior mortgage undisturbed
• Combined leverage commonly reaching approximately 85% of cost
• Governed by an intercreditor agreement negotiated before closing

How the position is sized and tested

Sizing starts with the senior loan. Once senior proceeds, amortization and reserve requirements are known, the mezzanine piece is measured against the remaining gap and then tested for combined coverage: whether stabilized cash flow services both positions with an acceptable cushion. That combined test, not the mezzanine loan in isolation, is the binding constraint on proceeds.

Underwriting also examines the senior loan documents themselves. Many prohibit subordinate debt outright, restrict transfers of equity interests, or require the senior lender’s consent to a pledge. Establishing whether the senior loan permits a mezzanine position — and on what conditions — is the first diligence item, because a structure the senior lender will not approve cannot close regardless of how the property performs.

Repayment is event-driven rather than amortization-driven. Mezzanine terms generally run one to five years and are aligned to a specific exit: the sale of the asset, a recapitalization, or a permanent refinance that retires both positions. Where the senior loan matures first, the mezzanine maturity and any extension mechanics must be coordinated with it.

Where mezzanine capital is most useful

The clearest use is an acquisition where senior proceeds come in below the sponsor’s underwriting. Rather than contributing additional equity or resizing the purchase, the sponsor funds the shortfall with subordinate debt at a fixed cost. A second common use is a recapitalization that returns equity to existing partners without refinancing an in-place senior loan carrying attractive terms or a prohibitive prepayment penalty.

Mezzanine capital is also used above senior loan-to-cost on construction and repositioning projects, where the senior construction lender stops short of the total capital required. In each case the analysis is the same: whether the incremental capital improves returns after accounting for its cost, and whether the property’s cash flow and value support both positions through the full business plan rather than only at stabilization.
