Where mezzanine sits in the capital stack
Think of a deal’s funding as a stack: the senior mortgage is at the bottom (lowest risk, lowest cost, paid first), the sponsor’s equity is at the top (highest risk, highest return, paid last), and mezzanine debt sits in between. It is repaid after the senior lender but before the equity, which is why it commands a rate above the mortgage but below the return equity expects.
Mezzanine debt is usually secured differently from a mortgage. Rather than a lien on the real estate (which the senior lender holds), the mezzanine lender takes a pledge of the membership interests in the LLC that owns the property. If the borrower defaults, the mezzanine lender can foreclose on that ownership interest and step into control far faster than a traditional mortgage foreclosure.
What it costs and why sponsors use it
Mezzanine money is more expensive than senior debt because it takes more risk — it is repaid later and is effectively second in line. In exchange for that gap-filling capital, the sponsor preserves more of the equity upside than they would by bringing in an equity partner for the same dollars. It is a leverage decision: pay a higher rate on a slice of debt, or give away a share of the profit forever.
It is a commercial tool, not a single-family one. You will see mezzanine financing on apartment complexes, development projects, and larger value-add deals — situations with enough scale and a clear business plan to support a multi-layer capital stack.
Pros and cons
Pros
- Adds leverage beyond what the senior lender will fund
- Cheaper than raising the same dollars as equity
- Lets the sponsor keep more of the upside
- Faster lender remedy (UCC pledge) can mean more flexible terms
Cons
- More expensive than the senior mortgage
- Adds risk — over-leverage can wipe out equity in a downturn
- Complex documentation and an intercreditor agreement required
- A commercial-scale tool — not for small residential deals
Frequently asked questions
How is mezzanine financing secured?
Typically by a pledge of the equity interests in the entity that owns the property, not by a mortgage lien on the real estate itself (the senior lender holds that). On default, the mezzanine lender can foreclose on the ownership interest and take control of the property-owning entity.
Is mezzanine financing debt or equity?
It is debt, but it sits closer to equity in risk and return because it is repaid after the senior loan. Some mezzanine structures include an equity “kicker” (a small share of the upside) on top of the interest rate, which blurs the line further.
