Property Capital Stack: Senior Debt, Mezzanine and Equity — How Claims on Cash Flow Differ

A property’s capital stack describes the hierarchy of claims on the asset and its cash flows. At the base are senior loans: bank or institutional mortgage debt secured by a legal charge over the property. Senior debt typically benefits from the strongest priority in enforcement and lower coupon rates because lenders have first claim to sale proceeds and covenant protections such as loan-to-value (LTV) and debt-service coverage ratios.

Above senior debt sits mezzanine finance or subordinated debt. Mezzanine lenders accept higher risk in return for higher yields; they sit behind senior lenders but ahead of equity in the cash flow waterfall. Mezzanine may be unsecured or secured via pledge arrangements and often includes equity kickers or payment-in-kind features that increase complexity and upside sharing.

Equity investors absorb the first losses but capture residual upside after all debt claims are met. Equity can be structured as preferred equity with fixed distributions and limited upside, or as common equity with variable income and capital gains. Institutional-grade equity strategies use diversification, active asset management and leverage control to smooth returns—benefits historically less available to small retail savers.

For fractional investors, these distinctions are vital. Fractional claims that mimic equity carry higher volatility and dependency on active management and exit outcomes, while fractional debt-like instruments prioritise income predictability but require scrutiny of borrower quality, security and enforcement mechanisms. Clear disclosure of where a fractional interest sits in the capital stack is therefore a principal due-diligence item.
