Capital Stack in Real Estate: Layers, Risk, Who Gets Paid

The capital stack is the full list of money used to buy and improve a property, ranked by who gets paid first and who takes losses first. In a typical multifamily deal, that means senior debt at the bottom, then any mezzanine debt, then preferred equity, then common equity on top. Know where your dollars sit in that order and you know most of what you need to judge a deal’s risk, return and control.

This guide walks through each layer, shows a worked example with real arithmetic, explains mezzanine debt and how it is secured, and gives you a checklist for reading any stack before you commit capital.

TL;DR

• The capital stack ranks every source of money in a deal by payment priority. Debt is paid before equity, and common equity is paid last.
• Four layers are possible: senior debt, mezzanine debt, preferred equity and common equity. Many multifamily deals use only senior debt and common equity.
• The lower you sit, the safer you are and the less upside you get. The higher you sit, the more you risk and the more you can earn.
• Mezzanine debt is usually secured by a pledge of ownership interests in the borrowing entity, not a lien on the building.
• Before you invest, read the loan agreement, the operating agreement, the waterfall and any intercreditor agreement. The stack on a pitch deck is only a summary.

What the capital stack actually shows

Think of the stack as a ranking, not a picture of who owns the building. Real estate finance scholar Stace Sirmans defines it as the set of claims financing a property, ordered by payment priority. That ordering answers two questions at once: who gets cash first, and who absorbs the first dollar of loss.

The answer to the second question is the one many new investors miss. The most junior claim absorbs the first dollar lost, and the most senior claim absorbs the last. That is why a lender at 65% of value can sleep at night while the equity partner on top watches occupancy numbers every month.

The stack matters for three reasons:

1. Risk. Your position decides how much value can disappear before you lose a dollar.
2. Return. Higher risk is paid for with higher target returns. Moving down the stack toward debt, risk and potential return both fall.
3. Control. Each layer carries its own rights and obligations, from voting and approval rights to remedies when a deal goes sideways.

The four layers, from bottom to top

Senior debt

Senior debt is the first mortgage. It sits at the bottom of the stack, carries the lowest risk and is paid first. If the borrower defaults, the lender can take possession of the asset. Because it is protected by a recorded lien on the property, it is priced as the cheapest capital in the deal.

For most multifamily buyers this is the loan that does the heavy lifting. Which loan you qualify for depends heavily on unit count, and we break that down in our guide to multifamily financing options for 2-4 unit and 5+ unit properties.

Mezzanine debt

Mezzanine debt sits between the senior loan and the equity. It is subordinate to the senior mortgage, so it is paid after the senior lender, and it charges more for taking that position. We cover it in detail in the next section because it is the layer people misunderstand most.

Preferred equity

Preferred equity is an ownership interest, not a loan. It has priority distribution rights over common equity but sits behind all debt. In practice, a preferred investor receives a stated return before the common investors see a cent. Sirmans describes the common layer as the residual claim: it receives whatever is left after every other layer is satisfied.

The key difference from mezzanine debt is the remedy. A preferred investor generally cannot foreclose on the property, so protection comes from the documents: approval rights, return thresholds and what happens if the sponsor misses a payment.

Common equity

Common equity is the top of the stack. It is the riskiest layer and is paid last, but it can capture unlimited upside and keeps ultimate control over property decisions, subject to lender covenants. In a syndication, the sponsor (general partner) and the passive limited partners usually hold common equity, with the split of profits set in the operating agreement.

Quick comparison

Mezzanine debt: what it is and how it is secured

Mezzanine debt is subordinate real estate debt positioned behind the senior mortgage and ahead of equity. The detail that trips people up is the collateral. In its Multifamily Guide, Fannie Mae describes mezzanine debt as debt secured by a pledge of the borrower’s direct or indirect equity interests, not by a lien on the property itself. The lender’s remedies and priority are also governed by the loan and intercreditor documents.

What does that mean in plain terms? If the borrower stops paying the mezzanine lender, the lender does not foreclose on the building. It can move against the ownership interests in the entity that owns the building, which can mean the mezzanine lender ends up controlling the property without a traditional foreclosure. That is why the intercreditor agreement, which sets out how the senior and mezzanine lenders deal with each other, matters so much.

Why sponsors use it

Mezzanine debt adds leverage. If a senior lender will lend only up to a certain share of value, mezzanine financing fills part of the gap so the sponsor writes a smaller equity check. Whether that strengthens or strains the project depends on the exit: when rents and values grow as planned, the extra leverage amplifies equity returns, and when they do not, the extra debt service squeezes cash flow.

What it means if you are a passive investor

More layers mean more claims ahead of you. If a sponsor adds mezzanine debt to a deal you are evaluating, ask three questions:

• What are the total debt payments now, and does the property’s net operating income (NOI) cover them with room to spare?
• What happens if the business plan runs 12 months late?
• What rights does the mezzanine lender have over the entity if a payment is missed?

A worked example: $10 million apartment deal

The numbers below are a hypothetical illustration, not a real deal. They show how the ranking works when a sale does not go as planned.

Each layer has an attachment point, the percentage of value where it starts being exposed, and a detachment point, where it is fully covered. Here the senior loan covers 0% to 65%, mezzanine 65% to 75%, preferred equity 75% to 80%, and common equity 80% to 100%. Fairbridge, a commercial lender, uses the same attachment-point idea to compare risk and reward by position.

Scenario 1: the sale goes to plan

The property sells for $12,000,000. The senior lender takes $6,500,000, mezzanine takes $1,000,000 plus interest, preferred takes $500,000 plus its stated return, and the common equity holders split everything left over. The top of the stack earns the most because it carried the most risk.

Scenario 2: values drop 20%

The property sells for $8,000,000. Senior ($6,500,000), mezzanine ($1,000,000) and preferred ($500,000) are all repaid principal, which totals exactly $8,000,000. Common equity receives nothing. The whole $2,000,000 cushion was consumed.

Scenario 3: values drop 28%

The property sells for $7,200,000. Senior is repaid in full. Mezzanine receives $700,000 of its $1,000,000. Preferred and common receive zero. The senior lender never took a loss, which is the entire point of its position.

Notice what the example teaches. Your risk is not just your own check size, it is the amount of capital ahead of you and the cushion behind you. Upon sale or refinance, the bottom position is paid first and losses run from the top down.

Not every deal has four layers

The full four-layer structure is common in larger commercial deals, but it is not required. A multifamily acquisition might include only senior debt and common equity. Smaller deals, such as a duplex or fourplex bought with a conventional loan and your own cash, have a two-layer stack by default.

The structure should follow the deal. Ask why each layer exists. A sponsor who can explain in one sentence why mezzanine debt or preferred equity is in the deal, and what happens to it at refinance or sale, is usually a sponsor who has stress-tested the plan.

How to read a capital stack before you invest

Here is the process we use when we analyze a deal.

1. Write the stack as a table. List each layer, the dollar amount, the percentage of total capitalization and the cost (interest rate or preferred return).
2. Find your attachment point. Add up all the capital ahead of you. That is the amount of value that has to disappear before you take your first loss.
3. Measure the cushion behind you. How much equity sits below the sale price you would lose money at? A thin cushion means little room for error.
4. Test the debt service. Divide stabilized NOI by total annual debt payments across every debt layer, not only the senior loan. Check the result against the lender’s minimum debt-service requirement in the loan documents.
5. Check the maturity dates. A loan that matures before the business plan is done forces a refinance or sale at the wrong time.
6. Read the waterfall. Find the preferred return, any catch-up and the split of profits above it. Two deals with the same stack can pay very differently.
7. Stress the exit. Rerun the deal with lower rents, higher expenses and a higher exit cap rate. See which layer breaks first.

Debt or equity: where should you sit?

There is no universally right layer. Investors may choose debt positions for steady income or equity positions for growth. Use these criteria:

• Income now versus growth later. Debt pays on schedule. Common equity usually pays after the business plan works.
• Appetite for loss. If a 20% drop in value is unacceptable, you want to sit lower in the stack.
• Control. Active investors who want a say in decisions generally need to be in the common equity or sponsor position.
• Tax goals. Debt interest is typically ordinary income, while equity ownership can bring depreciation and other tax benefits. Talk to a CPA who works with real estate investors before choosing a position based on tax outcomes.

High earners we work with usually land in common equity, either as passive limited partners or as the sponsor of their own small apartment deal. That is where the tax benefits and the upside live, and it is also where understanding the stack matters most, because you are last in line.

Is capital stacking legitimate?

Yes. Layering debt and equity is a standard and common way to finance commercial property. What varies is whether a specific structure is enforceable and safe, and that depends on the documents and the law that applies. Fannie Mae’s guidance on mezzanine financing and preferred equity shows how formal these arrangements are: the lender’s rights and priority depend on the loan documents and intercreditor terms.

So a stack is not a red flag. A stack you cannot verify is. Before you wire money, ask to see:

• The senior loan agreement and any guarantees
• The mezzanine or preferred equity agreement
• The operating or partnership agreement, including the waterfall
• The intercreditor agreement, if there is more than one lender
• Security instruments, such as UCC filings for pledged equity interests
• Leverage and debt-service tests, plus cure and standstill rights
• Remedies on default, including foreclosure and ownership-transfer provisions

Have a real estate attorney review these before you sign. A sponsor who is reluctant to share them has told you something useful.

Perspective: what we tell students about the stack

Most people learn the capital stack as vocabulary and then forget it. We teach it as a decision tool. Every deal we review starts with one question: who is in front of me, and how much room do I have if the plan slips?

The biggest mistakes we see are not exotic. They are investors who focus on a projected return and never ask where they sit, sponsors who stack on debt to shrink the equity check and leave no cushion for a slow lease-up, and buyers who assume the senior lender will be flexible when the loan matures. Concessions rise, NOI softens, and the refinance does not pencil. The layer on top gets hit first, every time.

Our view is simple: learn to build the stack yourself. When you can raise capital, structure it and explain it in plain English, you stop depending on someone else’s pitch deck. That is the skill that takes you from buying your first small property to running larger deals with other people’s money.

FAQ

What is a capital stack in real estate?

It is the structure of all capital used to finance a property, ranked by priority of payment. Senior debt is paid first, followed by mezzanine debt, preferred equity and common equity. The ranking also shows who takes losses first, which is the reverse order.

Who gets paid first in the capital stack?

The senior lender is paid first, then mezzanine lenders, then preferred equity investors, and finally common equity. Common equity is paid only after the other parties receive their entitled funds. In exchange for going last, common equity holders have the most upside.

Is mezzanine debt secured by the property?

Usually not directly. It is typically secured by a pledge of the ownership interests in the entity that owns the property, rather than a mortgage on the building. If the borrower defaults, the mezzanine lender may be able to take control of that entity under the terms of the loan and intercreditor documents.

What is the difference between mezzanine debt and preferred equity?

Mezzanine debt is a loan with interest and a maturity date, secured by equity interests. Preferred equity is an ownership stake that receives a stated return before common equity and sits behind all debt. The practical difference is remedies: a mezzanine lender has creditor remedies, while a preferred investor relies on rights written into the operating agreement.

Do small multifamily deals have a capital stack?

Yes, though it is simple. A fourplex bought with a mortgage and your own cash has two layers: senior debt and common equity. The same logic applies: the lender is paid first, and your equity absorbs the first loss.
