Mezzanine Loans and Preferred Equity: How the Capital Stack Works

Large commercial real estate purchases rarely close with a single loan and a check. A $100 million property might carry a $65 million first mortgage, $15 million of mezzanine debt and $20 million of the buyer’s own equity. The middle layer is the one most borrowers understand least, and it is the layer that decides whether a deal pencils. This guide explains what mezzanine loans and preferred equity are, where they sit in the capital stack, who uses them, what they cost, how they are documented, what can go wrong, and how to find lenders that offer them.

The Capital Stack in One Picture

Think of the money in a property as floors in a building. The ground floor is the senior loan: the first mortgage, secured by the real estate itself, paid first, cheapest. The top floor is common equity: the owner’s own money, paid last, most at risk, with the largest upside. Everything in between is “mezzanine” in the broad sense, and the word is borrowed from exactly that architectural idea of a level between two main floors.

Two instruments fill that gap in most deals:

• Mezzanine debt is a loan, but it is not secured by the property. It is secured by the ownership interests in the entity that owns the property. If the borrower defaults, the mezzanine lender takes the company, and with it the building, subject to the senior loan.
• Preferred equity is not a loan at all. The provider becomes a partner in the ownership entity with a preferred return and a priority position ahead of the common equity. It is documented in the operating agreement rather than a loan agreement.

The two are economically similar from the borrower’s chair: both fill the space between what the senior lender will provide and what the sponsor can contribute, both cost more than the senior loan, and both come with strong remedies. They differ in legal form, in how senior lenders treat them, and in how quickly their remedies can be exercised.

Why the Gap Exists

Senior lenders size their loans on three limits: loan-to-value, debt service coverage and debt yield. A stabilized office building might support a first mortgage at 60% to 65% of value from a bank or life company, or up to 70% to 75% from a CMBS conduit. That leaves 25% to 40% of the purchase price to be covered by equity. For a $100 million building that is $25 million to $40 million of cash, which is more than most sponsors want tied up in one asset.

Mezzanine debt or preferred equity typically takes total leverage from the senior lender’s 65% up to 80% or 85% of value. The sponsor’s cash requirement drops from, say, $35 million to $15 million. The sponsor keeps more capital for the next deal and, if the property performs, earns a higher return on the equity it did commit. That is the whole attraction: leverage without a bigger senior loan.

Who Uses Mezzanine Financing

This is institutional-scale financing. Most mezzanine lenders will not look at a piece under $5 million, and many prefer $10 million and up, because the underwriting, legal work and intercreditor negotiation take the same effort on a small deal as a large one. The borrowers are experienced sponsors, funds, REITs and developers with a track record, not first-time buyers.

Typical situations:

• Acquisitions where the senior loan tops out below the leverage the sponsor needs, and the sponsor would rather pay a higher rate on a slice than raise more equity.
• Construction, where construction lenders often cap their loan at 55% to 65% of cost and want the sponsor to fund the rest; a mezzanine piece or preferred equity can cover part of the required equity.
• Recapitalizations, where a property has grown in value but the first mortgage cannot be increased without a prepayment penalty or a full refinance. A mezzanine loan behind the existing first mortgage lets the owner pull equity out.
• Transitional assets, where a value-add plan needs capital that a permanent lender will not advance until the business plan is complete.

What It Costs

Mezzanine debt is priced for its position. Rates have historically run in the low double digits, with a wide range depending on the asset, the leverage, the sponsor and the market. Preferred equity usually carries a similar or slightly higher preferred return, often split between a current-pay portion and an accrued portion that is paid at exit. Both commonly come with origination fees of one to two points and exit fees.

Two features change the all-in cost more than the headline rate:

• Payment-in-kind (PIK) interest. Some mezzanine loans let part of the interest accrue to the balance rather than be paid monthly. That helps cash flow during a lease-up or renovation, but the balance grows and the accrued interest is repaid, with interest on it, at maturity.
• Minimum multiples and lookbacks. Many preferred equity deals guarantee the provider a minimum return multiple or an internal rate of return, however early the sponsor pays them off. A quick sale can mean paying for returns the provider never had time to earn.

Blended cost is what matters. A 65% senior loan at 6.5% plus a 15% mezzanine piece at 12% produces a blended rate on 80% of the capital of about 7.5%. Whether that is worth it depends on what the sponsor would otherwise earn on the equity it saved.

How the Pieces Fit Together: The Intercreditor Agreement

A senior lender does not have to allow mezzanine debt behind its loan, and many loan documents prohibit it. When it is allowed, the senior and mezzanine lenders sign an intercreditor agreement that governs how they behave toward each other. The borrower is not a party to it but lives with its consequences. The main points:

• Cure rights. The mezzanine lender can cure a borrower default on the senior loan, paying what the borrower failed to pay, to protect its own position.
• Purchase option. The mezzanine lender can usually buy the senior loan at par if the senior lender begins to foreclose.
• Standstill. The mezzanine lender agrees to pause its own remedies for a period while the senior lender acts.
• Qualified transferee. If the mezzanine lender forecloses and takes the ownership entity, the senior lender requires the new owner to meet its standards and to replace the guarantor.

Preferred equity avoids the intercreditor agreement because the provider is an owner, not a lender. Senior lenders still review it closely, and many require a “recognition agreement” that gives the preferred equity provider rights similar to a mezzanine lender’s.

The Remedy That Makes Mezzanine Different

A mortgage lender forecloses on real estate, a court-supervised process that in many states takes a year or more. A mezzanine lender forecloses on the ownership interests in the borrowing entity, which are personal property governed by the Uniform Commercial Code. A UCC foreclosure can be completed in weeks. The mezzanine lender ends up owning the company that owns the building, subject to the senior loan, and the sponsor’s equity is gone.

This speed is the reason mezzanine lenders accept the risk of being behind the first mortgage, and the reason sponsors should treat a mezzanine default as a far more immediate danger than a senior default. Preferred equity providers have their own remedies, usually the right to remove the sponsor as managing member and take control of the entity, which can be exercised even faster because no foreclosure is needed at all.

Advantages for the Borrower

• Less cash in the deal. The sponsor’s equity requirement falls, which is the point.
• Higher return on equity when the property performs, because the sponsor earns the spread between the property’s return and the cost of the mezzanine piece on money it did not have to contribute.
• No dilution of control with mezzanine debt; the lender has no say in management unless there is a default. Preferred equity usually comes with consent rights over major decisions.
• Interest deductibility. Interest on mezzanine debt is generally a deductible business expense; preferred returns on equity are generally not. Tax treatment depends on structure, so ask your accountant.
• Flexibility on payments. PIK options and accrual features can match a transitional property’s cash flow.
• A path to cheaper money. Once a value-add plan is complete and income has stabilized, the whole structure is typically refinanced with a larger, cheaper senior loan, retiring the mezzanine piece.

Disadvantages and Risks

• Cost. Double-digit rates, fees at both ends and minimum returns add up. If the business plan slips by a year, the mezzanine piece is the most expensive year of the delay.
• Speed of remedies. A missed payment can cost the sponsor the entire property within weeks, with no equity returned.
• Complexity. Two sets of loan documents, an intercreditor agreement, legal opinions and, for preferred equity, a renegotiated operating agreement. Legal fees are real money and the closing takes longer.
• Refinancing risk. Mezzanine terms are often shorter than the senior loan. If the property has not performed when the mezzanine piece matures, the sponsor must refinance it in whatever market exists then.
• Senior lender constraints. Some senior lenders will not permit subordinate financing at all; others cap total leverage or require it to be preferred equity rather than debt.

Mezzanine Debt or Preferred Equity: Choosing

The choice is often made for you. If the senior loan documents prohibit subordinate debt but allow equity partners, preferred equity is the only option. If the sponsor wants to keep management control and deduct the cost, mezzanine debt is preferable. Preferred equity tends to be more flexible on current pay and more expensive overall; mezzanine debt is more standardized and cheaper when the sponsor qualifies. Construction deals lean toward preferred equity because construction lenders dislike additional debt during the build.

What Lenders Will Ask For

Expect the same package a senior lender wants, plus a focus on the business plan and the sponsor:

• The senior loan term sheet or existing loan documents, so the mezzanine lender can assess the structure it is sitting behind.
• A detailed pro forma with the plan that justifies the leverage: lease-up schedule, renovation budget, exit assumptions.
• The sponsor’s track record on similar plans, with realized returns.
• Personal financial statements, schedule of real estate owned, liquidity after closing.
• Entity organizational documents, because the collateral is the entity itself.
• Third-party reports, usually shared with the senior lender.

Terms to Negotiate

• Prepayment. Lockout periods and minimum interest. Ask for a step-down so an early sale is not punished for the full term.
• Cash management. Many mezzanine loans trigger a cash sweep if coverage falls below a threshold; know the trigger and the cure.
• Extension options. One or two extensions, conditioned on performance tests, give room if the plan runs long.
• Recourse carve-outs. Mezzanine loans are typically non-recourse with “bad act” carve-outs. Read the list: unauthorized transfers, misapplication of funds, environmental liability and voluntary bankruptcy filings are standard.
• Consent rights on leases, budgets and capital calls, especially with preferred equity.

Finding Mezzanine and Preferred Equity Providers

These providers are debt funds, private equity real estate firms, life insurance companies, specialty lenders and, increasingly, the mezzanine desks of banks that also hold the senior loan. They rarely advertise minimums, markets or pricing in public, which makes them hard to compare. On LenderMatrix, lenders publish the criteria they lend to: loan size, property types, states, leverage, recourse and timing. Searching the Mezzanine Debt loan type, or describing your deal once with Get Funding, shows which programs’ published criteria your deal meets. A potential match is a comparison against what each lender listed, not an approval, and every lender underwrites for itself.

A Worked Example

A sponsor is buying a $40 million multifamily property it plans to renovate. A bridge lender will provide 65% of cost, $26 million, at a floating rate. The sponsor wants to limit its equity to $6 million. The gap is $8 million. A mezzanine lender offers an $8 million loan at 12%, interest-only, with 1% in and 1% out, a two-year term with one extension, and PIK for half the interest during the first year. Total leverage reaches 85% of cost. The sponsor’s blended cost on $34 million of debt is about 8.6%. If the renovation lifts income enough to refinance at a 70% loan-to-value on a higher value in year three, the senior refinance retires both loans and the sponsor’s $6 million has earned the entire increase in value. If the plan stalls, the sponsor is paying 12% on $8 million with accrued interest growing, and a missed payment puts the whole property at risk within weeks. That is the trade.

Mezzanine Capital in Construction Deals

Construction is where the gap between a senior loan and the sponsor’s equity is widest. A construction lender typically advances 55% to 65% of total project cost and wants the sponsor’s equity funded first, before the first draw. On a $60 million project that is $21 million to $27 million of cash in the ground before the lender writes a check. Sponsors fill part of that with preferred equity more often than with mezzanine debt, for three reasons. Construction lenders are wary of additional debt during the build, when the collateral is a hole in the ground and a set of drawings. Preferred equity can be structured to fund alongside the senior draws rather than all at closing. And an equity partner’s consent rights over budget changes are easier for a construction lender to accept than a second lender’s foreclosure rights.

The economics are also different during construction. There is no income to pay current interest, so the preferred return accrues until stabilization or sale. The provider’s protection is the completion guarantee from the sponsor, the lender’s own completion and cost-overrun requirements, and the right to step in and take control if the sponsor fails to fund overruns. Read the “major decision” list in the operating agreement carefully: change orders above a threshold, changes to the construction contract, leasing guidelines and the decision to sell are usually on it.

How Senior Lenders See It

Senior lenders think about subordinate capital in terms of two questions: does it increase the chance the borrower defaults, and does it complicate their exit if the borrower does? Higher total leverage makes a default more likely, which is why senior lenders cap combined leverage and often require higher coverage when mezzanine debt is present. On the exit, the intercreditor agreement is designed to keep the mezzanine lender out of the senior lender’s way: standstills, qualified transferee tests, and a purchase option that gives the mezzanine lender a way to protect itself by buying the senior loan rather than fighting it.

Some senior lenders will only allow subordinate capital from a pre-approved list of institutional providers. Others require that mezzanine debt be held by a lender with a minimum net worth, so that the cure and purchase rights mean something. If you plan to add mezzanine capital, raise it with the senior lender before term sheets are signed; it is far easier to document at the start than to negotiate a consent later.

Questions to Ask a Mezzanine or Preferred Equity Provider

1. What is the minimum and maximum piece you will write, and in which states and property types?
2. Is your rate fixed or floating, and how much is current-pay versus accrued?
3. What are the fees at closing and at exit, and is there a minimum multiple or minimum return?
4. What is the term, what extensions exist, and what tests do they depend on?
5. Which senior lenders have you signed intercreditor agreements with before?
6. What are your cash management triggers, and how is a trigger cured?
7. What consent rights do you require, and what happens if we disagree?
8. What is your remedy on a payment default, and how long before you exercise it?
9. Will you require a replacement guarantor if you take the ownership interests?
10. How long does your closing take, and what legal budget should we expect on your side?

LenderMatrix is a marketplace, not a lender, and nothing here is financial, tax or legal advice. The structures described are complex and carry real risk; involve counsel and an accountant who work with them regularly before signing anything.

Summary

Mezzanine loans and preferred equity let experienced sponsors put less cash into large deals and earn more on the cash they do commit, at the price of higher cost, more complexity and the fastest remedies in commercial real estate. They belong in transitional and large transactions with a clear path to a cheaper refinance, and they belong in the hands of borrowers who have read every page of the intercreditor and operating agreements. Compare providers on published criteria before you talk to any of them, and bring counsel who has closed these structures before.
