Mezzanine financing, like preferred equity, is driven by the 2026 maturity wall and the gap it creates between senior debt and the capital a deal requires. When senior debt does not cover the full requirement, sponsors turn to subordinate capital, and mezzanine debt is one of the two primary instruments for the purpose, targeting returns in the 10 to 15 percent range and allowing sponsors to increase leverage beyond what a senior lender alone provides. The wave of loans maturing into a higher-rate environment, with average maturing rates well below current new-loan rates, generates strong demand for the subordinate capital that bridges refinancing and recapitalization gaps.
Mezzanine's structure carries distinct features and risks relative to preferred equity. As debt, it appears as a liability increasing total leverage, and interest payments reduce net income, less favorable balance-sheet treatment than preferred equity's equity-like presentation. It typically secures itself through a pledge of the ownership interest rather than a direct property lien, and its conversion-to-equity feature provides recovery if the borrower defaults. A notable structural consideration shapes who holds it: mezzanine loans present challenges for REITs, because while REITs are explicitly permitted to hold interests in mortgages, the rules are silent regarding mezzanine loans, an ambiguity that has led many REITs to exercise caution in owning them, channeling mezzanine provision toward other capital sources. The constraints are the subordinate position behind senior debt, the higher risk reflected in the elevated rates, and the structuring complexity. The maturity wall provides strong, sustained demand, and mezzanine, alongside preferred equity, is positioned to meet it.
