Mezzanine Financing: When and How to Use It

Every CRE deal has a capital stack, and every capital stack has a gap.

The senior lender will go to 65% of the deal. Your equity investors want to contribute 20%. That leaves 15% of the capitalization unaccounted for, and the deal doesn't close until someone fills it.

That's where mezzanine financing lives. It's the layer between senior debt and equity, more expensive than the first, cheaper than the second, and often the difference between a deal that closes and one that dies on the whiteboard.

Mezzanine is also one of the most misunderstood products in CRE finance. Borrowers confuse it with preferred equity. They underestimate its cost. They miss the intercreditor complexities. And they reach for it in situations where it doesn't belong.

This week we're breaking down mezzanine financing: what it actually is, how it's structured, what it costs in 2026, when it makes sense, and when it's the wrong tool for the job.

What Mezzanine Financing Actually Is

Mezzanine debt is a loan secured not by the property itself, but by the ownership interests in the entity that owns the property.

That distinction matters. The senior lender holds a mortgage on the real estate. The mezzanine lender holds a pledge of the equity in the borrowing entity. If the mezz loan defaults, the mezz lender doesn't foreclose on the building. They foreclose on the ownership of the company that owns the building, through a UCC foreclosure process that's dramatically faster than a mortgage foreclosure.

In practice, a UCC foreclosure can be completed in 30-60 days, versus the months or years a judicial mortgage foreclosure can take. This speed is precisely why mezz lenders accept a junior position: their remedy is fast and severe.

Where It Sits in the Capital Stack

A typical capitalization with mezzanine:

The mezzanine slice sits behind the senior loan in payment priority but ahead of all equity. If the deal goes well, mezz gets its coupon and principal back. If the deal goes badly, mezz absorbs losses before the senior lender but after the equity is wiped out.

Mezzanine vs. Preferred Equity

These two products fill the same slot in the capital stack and are constantly confused. The differences matter:

Mezzanine debt:

• Is a loan, with a maturity date, interest rate, and default remedies
• Secured by a pledge of ownership interests (UCC-1 filing)
• Requires an intercreditor agreement with the senior lender
• Interest is deductible as an expense
• Remedy: UCC foreclosure on the equity

Preferred equity:

• Is an equity investment with a preferred return, not a loan
• No lien, no UCC filing; rights come from the operating agreement
• Often doesn't require senior lender consent (though many loan documents now restrict it)
• Returns are distributions, not deductible interest
• Remedy: takeover rights defined in the operating agreement ("change of control")

Senior lenders generally prefer preferred equity over mezz because there's no second lender with foreclosure rights. That's why some senior loan documents prohibit mezzanine debt entirely but permit structured preferred equity. If your senior term sheet is silent on this, ask before you build your stack.

What Mezzanine Costs in 2026

Pricing depends on leverage, asset quality, and sponsor strength, but current ranges:

• Coupon: 10-14% all-in for most CRE mezz
• Structure: Often split between current pay (e.g., 8-10%) and accrued/PIK interest (2-4%)
• Origination: 1-2%
• Exit fees: Common, 0.5-1.0%
• Term: Usually coterminous with the senior loan
• Attachment point: Typically takes total leverage from 60-65% up to 75-85%

The blended math is what matters. Consider a $20M deal:

• Senior: $13M (65%) at 6.5% = $845K/year
• Mezz: $3M (15%) at 12% = $360K/year
• Blended debt cost: $1.205M on $16M = 7.53%

You've taken leverage from 65% to 80% and your all-in debt cost went from 6.5% to 7.53%. Whether that trade makes sense depends entirely on what the extra $3M of leverage does for your equity returns.

When Mezzanine Makes Sense

1. Closing the Gap on an Acquisition

The classic use case. Senior proceeds plus available equity don't reach the purchase price. Mezz fills the gap, the deal closes, and the sponsor refinances the whole stack once the business plan matures.

2. Reducing the Equity Check to Boost Returns

If your equity targets a 15%+ IRR and mezz costs 12%, every dollar of mezz that replaces equity is accretive, as long as the deal performs. Leverage amplifies both directions, but on a strong deal with conservative senior debt, a modest mezz slice can meaningfully lift equity returns.

3. Recapitalizations and Partner Buyouts

You need capital to buy out a partner or return capital to investors, but you don't want to refinance a favorable senior loan. Mezz behind the existing senior (with lender consent) can unlock the capital without disturbing the first mortgage.

4. Construction and Value-Add Stacks

Development deals routinely use mezz to bridge between construction senior debt (60-70% LTC) and the total budget. The mezz retires at stabilization when the permanent loan sizes to the stabilized value.

5. Preserving an Assumable or Below-Market Senior Loan

If your property carries a 4% senior loan from 2021 that's assumable or has years left, refinancing it to pull cash out would be value-destructive. Mezz lets you access equity while keeping the below-market senior in place.

When Mezzanine Is the Wrong Tool

When the Deal Only Works at Maximum Leverage

If your deal needs 85% leverage to pencil, the problem is the deal, not the capital stack. Mezz on top of a thin deal is how sponsors lose properties. The 2021-2022 vintage deals now in distress are disproportionately the ones that stacked mezz to peak leverage at peak pricing.

When Cash Flow Can't Cover the Blended Debt Service

Mezz coupons are demanding. If the property's NOI can't cover senior plus mezz current pay with a reasonable cushion, you're depending on everything going right. Lenders will check this; you should check it first.

When the Senior Lender Prohibits It

Many senior loan documents ban junior debt outright. Layering mezz without consent violates your loan covenants, and can trigger recourse carve-outs. Always clear the intercreditor path first.

When Preferred Equity Fits Better

If the senior lender won't allow mezz, or the UCC foreclosure remedy is too aggressive for your partnership, structured preferred equity may accomplish the same capitalization with less structural friction.

When You Can Just Raise More Equity

Mezz is faster than raising new LP equity, but it's not always better. If you have access to equity at reasonable terms, the permanence and flexibility of equity often beats a hard-maturity, double-digit-coupon loan.

The Intercreditor Agreement: Where Mezz Deals Live or Die

Every mezzanine loan behind a mortgage requires an intercreditor agreement between the senior and mezz lenders. This document governs their relationship and directly affects you:

• Cure rights: The mezz lender's right to cure defaults on the senior loan (they'll pay your late payment to protect their position)
• Purchase rights: The mezz lender's option to buy out the senior loan at par during a default
• Foreclosure standstill: Restrictions on when and how the mezz lender can exercise its UCC remedies
• Qualified transferee provisions: Who's allowed to end up owning the equity if the mezz lender forecloses
• Replacement guarantor requirements: If the mezz lender takes over, someone must replace your guarantees on the senior loan

Negotiating an intercreditor takes time, often weeks, and some senior lenders simply won't sign one. Build this into your closing timeline, and get both lenders talking early.

For borrowers, the key insight: in a stress scenario, the mezz lender can take the keys to your entity in 30-60 days. That's not a hypothetical. It's the design. Never put mezz on a deal whose downside cases you haven't honestly stress-tested.

How to Run a Mezz Process

1. Confirm Senior Lender Consent First

Before you talk to any mezz lender, confirm your senior loan documents permit junior financing and understand the conditions. If you're arranging both simultaneously, tell each lender about the other on day one.

2. Model the Full Stack

Build the blended debt service, the combined DSCR, and the downside scenarios. Know your break-even occupancy and rent levels with the full stack in place.

3. Compare Mezz Against Preferred Equity

Run both structures. The pricing is often similar; the structural differences (tax treatment, remedies, senior consent) usually drive the decision.

4. Negotiate the Cure and Notice Provisions

As the borrower, you want maximum notice and cure periods before the mezz lender can exercise remedies, and clear reinstatement rights if defaults are cured.

5. Shop the Slice

Mezzanine pricing varies widely between capital sources. Debt funds, mortgage REITs, and family offices all play in this space with different return targets. A competitive process on the mezz slice can save 100-200 bps, which is real money at these coupon levels.

The Bottom Line

Mezzanine financing is a precision tool: expensive, structurally complex, and exactly right for specific situations.

• What it is: Debt secured by the ownership of the property entity, sitting between senior debt and equity
• What it costs in 2026: 10-14% coupons, taking total leverage to 75-85%
• When it works: Closing capitalization gaps, boosting equity returns on strong deals, recaps, construction stacks, and preserving below-market senior loans
• When it doesn't: Thin deals that need maximum leverage to pencil, properties whose cash flow can't cover the blended debt service, and stacks the senior lender hasn't blessed
• The fine print: The intercreditor agreement and the UCC foreclosure remedy are where the real risk lives

Used well, mezz closes deals and amplifies returns. Used badly, it's the fastest way in commercial real estate to lose a property you still believe in. The difference is honest underwriting of the downside before you sign.
