Mezzanine Capital: Definition, Costs and Applications

mezzanine capital closes the gap between bank loans and equity – and is thus the leverage with which developers handle more projects in parallel.

Last updated: 18 July 2026 · Reviewed by Jürgen Kronawitter

In brief: Mezzanine capital is financing capital between equity and debt capital: it is subordinated to bank financing, but economically treated as equity. Real estate professionals use it to lower the equity ratio – typically as a terminal subordinated loan with terms ranging from 12 to 48 months and significantly higher interest rates than the senior loan.

How does mezzanine capital work?

In the capital structure, mezzanine stands between the first rank Senior loans and the Equity of the sponsor. Legally, it is usually considered Subordinated loans Designed – often Partial with a share of profits; or Equity kicker. Because the mezzanine lender is only served after the bank in the liquidation case, many banks accept it as an economic equity: The developer has to commit fewer own funds.

Typical basic data and use cases

  • Volume and leverage: Mezzanine often raises the total funding to 85–95 % of project costs.
  • Term: Project-accompanying 12 to 48 months, final, repayment from sale or refinancing.
  • coupon: clearly double digits possible – depending on rank, finish and project phase; details in the guide Mezzanine interest rates.
  • Operation: Equity gap at project start, land purchase, construction phase, capital release for parallel projects.

Does mezzanine work? The return logic

Mezzanine is expensive capital – but it replaces the most expensive capital ever: equity. The decisive factor is the comparison at project level: Does the additional leverage increase the return on equity more than the mezzanine interest burden the margin? This is often the case for solid projects with a clear exit; with tight margins, mezzanine can also override a project.
