Mezzanine debt is a loan that sits between the senior mortgage and the owner’s equity in a large commercial deal, secured not by the property itself but by a pledge of the borrower’s ownership interest in the entity that holds the property or business. It carries higher interest than a bank loan, typically 10% to 14%, because the lender gets paid only after the senior lender is made whole. So how does mezzanine debt work in practice? It fills the gap between what a senior lender will advance and what the sponsor wants to put in as equity, and it gives the junior lender a fast, UCC-based path to take over the ownership entity if the borrower defaults.
Where It Sits in the Capital Stack
Every commercial deal has a repayment hierarchy. Senior debt sits at the top and gets paid back first in any sale, refinancing, or liquidation. Mezzanine debt sits one level below. Below it come preferred equity and then common equity, held by the sponsors who put the deal together.
The order controls what happens when a deal goes sideways. If the asset is sold or the company is liquidated, the senior lender collects its full principal and interest before a dollar reaches the mezzanine lender. The mezzanine lender then collects everything owed to it before preferred equity sees any return. Common equity gets whatever is left, which in a distressed sale may be nothing. Higher in the stack means safer money and lower returns; lower means the opposite.
What Secures the Loan
A traditional mortgage is secured by the real estate. A mezzanine loan is not. Instead, the lender takes a pledge of the borrower’s membership units or partnership shares in the entity that owns the asset, and that pledge is governed by Article 9 of the Uniform Commercial Code.1Cornell Law School. UCC – Article 9 – Secured Transactions
That difference drives everything else about how mezzanine debt works. If the borrower defaults, the lender does not file a judicial foreclosure action against real estate. It sells the pledged ownership interests through a UCC sale.2Cornell Law School. UCC 9-610 – Disposition of Collateral After Default In a nonconsumer transaction, only 10 days’ notice is required before holding a public or private sale of the collateral.3Cornell Law School. UCC 9-612 – Timeliness of Notification Before Disposition of Collateral The buyer at that sale ends up owning the entity, and the entity continues to own the property subject to the senior mortgage.
What It Costs
Mezzanine interest usually comes in two layers. Cash interest is paid regularly, often monthly or quarterly, at rates generally between 10% and 14%. On top of that, many deals include payment-in-kind interest, which lets the borrower defer part of the coupon. The deferred amount gets added to the loan balance and compounds, so the eventual payoff is larger than the original principal.
Many agreements also give the lender an equity “kicker”: a warrant or option to buy a small ownership stake at a fixed price. Between the coupon, the PIK, and the equity upside, mezzanine lenders typically target total returns of 12% to 17%. Borrowers should also plan for an origination fee at closing, commonly 1% to 3% of the loan amount.
Covenants and Term
Mezzanine lenders ride along with the borrower through ongoing financial covenants. The two most common are a minimum debt-service coverage ratio and a maximum loan-to-value ratio. DSCR minimums are typically set at 1.20x to 1.30x on total debt, meaning the property or business must earn at least $1.20 to $1.30 of net income for every dollar of debt service. Combined LTV caps often sit around 80% to 85% of the asset’s appraised value.
The loans are medium-term, usually five to seven years, and most are interest-only, with the full principal balance due at maturity. That structure forces the borrower to plan an exit from day one: a sale, a refinancing, or a business event that generates enough cash to clear the balloon.
How the Two Lenders Coexist
Because the senior lender and the mezzanine lender share one borrower, their relationship runs through a formal intercreditor agreement. Two of its provisions matter most to understanding how the junior loan actually functions.
Cure Rights
If the borrower misses a payment on the senior loan, the mezzanine lender can step in and make that payment itself.4Fannie Mae. Intercreditor Agreement Without this right, the senior lender could foreclose on the property and extinguish the mezzanine position entirely. Cure rights are the mezzanine lender’s main defense against being wiped out by a senior default it had no part in causing.
Standstill Provisions
Standstill clauses go the other direction. For a set period after a default, often 90 to 180 days, the mezzanine lender cannot foreclose on the pledged equity or take other enforcement actions. This gives the senior lender room to stabilize the situation on its own terms.
Intercreditor agreements also sort out who can replace the property manager during a default. Under a standard framework, the mezzanine lender can replace the manager when certain defaults occur, but only if the senior lender has not already done so; if both have the right, the senior lender’s choice controls, and any replacement must meet the senior lender’s qualifications.4Fannie Mae.

When Personal Liability Kicks In
Mezzanine loans are generally non-recourse, so the lender’s recovery is normally limited to the pledged ownership interest and does not reach the borrower’s personal assets. Nearly every loan, though, includes non-recourse carve-outs, often called “bad boy guarantees,” that convert the debt into a full-recourse obligation if the borrower or a guarantor does certain things.
The usual triggers are:
- A voluntary bankruptcy filing by the borrowing entity or its parent is almost always a full-recourse trigger.5National Association of Insurance Commissioners. Statutory Issue Paper No. 113 – Mezzanine Real Estate Loans
- Fraud or misapplication of funds, such as diverting loan proceeds, rental income, or insurance payments.
- Unauthorized transfers, including selling, encumbering, or transferring the property or the pledged ownership interests without the lender’s consent.
- Taking on additional debt by granting a new lien or incurring borrowing beyond what the loan documents allow.5National Association of Insurance Commissioners. Statutory Issue Paper No. 113 – Mezzanine Real Estate Loans
- Breaking the single-purpose entity covenant, which requires the borrowing entity to engage in no other business activities.
Some carve-outs are negotiable. Borrowers can sometimes limit personal exposure to the lender’s actual damages rather than the full outstanding balance, depending on the lender and the borrower’s leverage.
What Default and Foreclosure Look Like
When the borrower stops paying or breaks a covenant, the mezzanine lender’s main remedy is to foreclose on the pledged ownership interests through a UCC sale. Because the collateral is personal property rather than real estate, the process skips the court proceedings that a mortgage foreclosure would require.2Cornell Law School. UCC 9-610 – Disposition of Collateral After Default
The sequence is usually straightforward. The lender sends a formal default notice to the borrower and any guarantors and notifies the senior lender and any other creditors. Before conducting a public or private sale, the lender must give at least 10 days’ advance notice, though most mezzanine lenders provide 30 or more days to let potential bidders evaluate the opportunity.3Cornell Law School. UCC 9-612 – Timeliness of Notification Before Disposition of Collateral From default notice to completed sale, the process typically runs 45 to 90 days.
The winning bidder, often the mezzanine lender itself, becomes the 100% owner of the entity that holds the asset. The underlying property remains subject to all existing liens, including the senior mortgage, and the new owner inherits the obligation to keep paying the senior loan.
Repayment and Exit
Mezzanine loans typically restrict early repayment to protect the lender’s expected return. A lockout period, usually one to two years, bars voluntary prepayment entirely. After the lockout, the borrower can prepay but owes a prepayment premium, often calculated as a percentage of the outstanding balance or through a yield-maintenance formula that compensates the lender for lost future interest.
Because most of these loans require a balloon payment at maturity, the exit plan is part of the original underwriting. Lenders want to see a realistic path to repaying principal in full, whether through a property sale, a cash-out refinancing, or a business event like an IPO or strategic acquisition. A borrower who stays current on interest for seven years but cannot refinance or sell at the end can still end up in default when the balloon comes due.
