Every time I sit down with a new investor and start talking about the capital stack, I can see the exact moment their eyes glaze over. Debt, mezzanine, preferred equity, common equity. It sounds like a finance exam. It's actually very simple once you strip away the jargon.

The capital stack is just the answer to one question: who put money into this deal, and in what order do they get paid back?

That's it. Everything else is details. Important details, but details that only make sense once you understand the basic framework.

Think of It Like a Building

Imagine a four-story building. The ground floor is the most protected. It's the first thing built and the last thing destroyed. The top floor has the best view, but it's the most exposed to the elements. If a storm takes the roof off, the top floor gets hit first. The ground floor barely notices.

The capital stack works the same way. Money at the bottom of the stack is the safest. Money at the top has the most upside but takes the first loss if things go wrong.

Let's walk through each layer.

Layer 1: Senior Debt (The Ground Floor)

This is the bank loan. It sits at the bottom of the stack, which means it gets paid first. Before anyone else sees a dollar, the bank gets its mortgage payment.

In a typical multifamily acquisition, senior debt makes up 60-75% of the total capital. If you're buying a building for $2 million, the bank might lend you $1.4 million. That $1.4 million is the senior debt.

Why does the bank get paid first? Because they demanded it. The loan is secured by the property itself. If you stop paying, they foreclose and take the building. That security is why bank debt is the cheapest money in the stack, typically 6-8% interest in the current market.

Key point: The bank doesn't share in the upside. If the property doubles in value, the bank still gets the same mortgage payment. They traded upside for security. That's the deal.

Layer 2: Mezzanine Debt (The Second Floor)

Sometimes the bank won't lend enough to cover the deal. You need $1.4 million, but the bank will only do $1.2 million. That leaves a $200,000 gap. Mezzanine debt fills that gap.

Mezzanine lenders sit above the bank but below the equity. They get paid after the bank but before any equity investors. Because they take more risk than the bank, they charge more. Mezzanine debt typically runs 10-15% interest, sometimes higher.

Mezzanine debt is usually secured by the ownership interest in the entity that owns the property, not by the property itself. If things go sideways, the mezzanine lender can't foreclose on the building directly. They can take over the LLC that owns the building. That's a meaningful legal distinction that matters when things get ugly.

When do you see mezzanine debt? Mostly on larger deals where the equity gap is significant and the sponsor doesn't want to raise more equity. On a $10 million acquisition where the bank lends $6.5 million and the sponsor has $1.5 million in equity, mezzanine debt might fill the remaining $2 million.

For smaller deals under $5 million, mezzanine debt is less common. The transaction costs of structuring it often don't justify the complexity. But you should understand what it's because you'll encounter it as you scale.

Layer 3: Preferred Equity (The Third Floor)

This is where it gets interesting for passive investors. Preferred equity sits above all the debt but below common equity. Preferred equity investors get paid a set return, usually 8-12%, before the common equity holders get anything.

Here's the simplest way to think about it. Preferred equity is like debt that pretends to be equity. The preferred investor gets a predictable return, similar to an interest payment, but they don't hold a lien on the property. They own a piece of the entity, with terms that say they get paid their return before the common equity splits the remaining profits.

Example: You buy a building for $2 million. The bank lends $1.4 million. You raise $400,000 in preferred equity at a 10% preferred return. You put in $200,000 of common equity.

The property generates $180,000 in NOI. Debt service takes $100,000. That leaves $80,000. The preferred equity investors get their 10% return first, which is $40,000. The remaining $40,000 goes to the common equity.

If the property underperforms and only produces $50,000 after debt service, the preferred equity still gets their $40,000. The common equity gets $10,000. If it only produces $30,000, the preferred equity gets the full $30,000 and the common equity gets nothing.

That's the deal. Preferred equity gets consistency. Common equity gets whatever is left, which could be a lot or could be nothing.

Layer 4: Common Equity (The Penthouse)

Common equity is the top of the stack. It's the riskiest position and the one with the most upside. Common equity holders are last to get paid, but they capture all the remaining profit after everyone else gets theirs.

In a syndication-model-explained-simply) or fund structure, common equity is typically split between the sponsor (the person running the deal) and the limited partners (passive investors). The split might be 70/30, 80/20, or some other arrangement depending on the deal structure.

Common equity is where wealth is really built. If the property appreciates significantly, or if the value-add-playbook-for-b-and-c-class-multifamily) plan works and NOI jumps, the common equity holders capture that gain. The bank doesn't benefit. The mezzanine lender doesn't benefit. The preferred equity gets their fixed return and nothing more. All the excess flows to common equity.

But the flip side is real. If the deal underperforms, common equity absorbs the loss first. If the property loses value, the common equity holders lose their investment before anyone else is affected.

This is why the position you occupy in the capital stack matters more than the total return number someone quotes you. An 18% return in a common equity position carries fundamentally different risk than a 10% return in a preferred equity position. The numbers alone don't tell you the story. The position tells you the story.

Why This Matters to You

Whether you're investing passively in someone else's deal or structuring your own acquisitions, understanding the capital stack changes how you evaluate risk.

If You Are a Passive Investor

Ask where your money sits in the stack. When a sponsor says "we're offering a 12% preferred return," understand what that means. You're in the preferred equity layer. You get paid before the common equity. But you're subordinate to the debt. If the property can't service its debt, your preferred return is at risk.

Questions to ask:

What's the loan-to-value ratio? The more debt ahead of you in the stack, the thinner the cushion if property values decline.

What's the debt service coverage ratio (DSCR-and-why-your-lender-cares))? A DSCR of 1.25 means the property generates 25% more income than needed to cover debt payments. That's your buffer. Below 1.1 and there's very little margin for error.

What happens if the preferred return can't be paid in a given quarter? Does it accrue and get paid later? Or is it simply lost? This is a critical term in any preferred equity structure.

If You Are Structuring a Deal

The way you build the capital stack determines your risk, your return, and your flexibility. More debt means more leverage and higher returns on equity when things go well, but tighter margins and more risk when they don't.

A conservative stack on a $2 million deal might look like:

Senior debt: $1.3 million (65% LTV)

Preferred equity: $400,000

Common equity: $300,000

An aggressive stack might look like:

Senior debt: $1.5 million (75% LTV)

Mezzanine debt: $200,000

Preferred equity: $200,000

Common equity: $100,000

The aggressive stack uses less of your own money and generates higher returns if the deal works. It also has less margin for error and more layers of obligation that must be met before you see a dollar.

There's no universally right answer. The right capital stack depends on the deal, the market, your risk tolerance, and your ability to manage through a downturn.

The One Thing to Remember

The capital stack is a pecking order. It tells you who eats first and who eats last. The people who eat first accept lower returns in exchange for more safety. The people who eat last accept more risk in exchange for more upside.

Every investment decision you make, whether you're putting $50,000 into a syndication or structuring a $5 million acquisition, starts with this question: where do I sit in the stack, and am I being compensated fairly for that position?

If you can answer that question honestly for every deal you evaluate, you will make better investment decisions than 90% of the people in this industry. Not because the concept is hard. Because most people never bother to ask.
