Why does one investor get paid back before another on the same project, even though they both put money into the exact same building? The answer has nothing to do with who invested more. It comes down to where each dollar sits in what real estate professionals call a capital stack, the layered order of debt and equity that decides who gets paid first, who takes on the most risk, and who earns the most upside if the project performs well. This guide walks through what a capital stack in real estate actually looks like, in plain terms, and why the order matters more than the total amount raised.
What a Capital Stack Actually Looks Like
Picture a project’s total funding as a tower built in layers. At the bottom sits senior debt, the largest and safest layer, since it gets repaid before anything else. Above that often sits a smaller layer of higher-cost debt or preferred equity. At the top sits common equity, the smallest layer in dollar terms but the one that carries the most risk and, if things go well, the most reward. Every layer above senior debt is, in effect, absorbing risk on behalf of the layers below it.
Senior Debt vs Mezzanine Debt in Real Estate
Senior debt vs mezzanine debt real estate financing is one of the first distinctions investors need to understand. Senior debt is the first loan registered against the property, usually provided by a bank or an insured lender, and it gets repaid before any other source of capital. It typically carries the lowest interest rate in the stack because it carries the least risk. Mezzanine debt sits above senior debt and below equity. It is still debt, meaning it has to be repaid on a set schedule, but it is subordinate to the senior loan, which means it only gets paid after the senior lender is satisfied. Because it takes on more risk than senior debt, it charges a meaningfully higher rate.
Preferred Equity vs Common Equity
This is the equivalent distinction on the equity side of the stack. Preferred equity investors are entitled to a set return before common equity investors see anything, similar to how mezzanine debt sits ahead of common equity but behind senior debt. Preferred equity does not usually share in the additional upside if a project performs above expectations. Common equity, often held by the sponsor and its co-investors, is paid last but keeps the majority of any profit once every other layer above it has been paid its share.
How Capital Stack Risk and Return Work Together
These move in the same direction throughout the stack. Senior debt takes the least risk and earns the lowest return. Mezzanine debt and preferred equity sit in the middle, taking on more risk in exchange for a higher fixed or semi-fixed return than senior debt. Common equity takes on the most risk, since it absorbs losses first if a project underperforms, but it also keeps the most upside if the project outperforms its underwriting. This is why the order of the stack matters as much as the amount of money in it. Two investors can put in the same dollar amount and end up with very different outcomes depending on where in the stack their money sits.
How Developers Finance Large Projects
This almost always means combining several of these layers rather than relying on just one. A large purpose-built rental tower is too capital-intensive for equity alone to fund efficiently, and too risky for a lender to finance entirely with debt. Layering senior debt, sometimes a layer of mezzanine debt or preferred equity, and a base of common equity, lets a developer fund a large project while spreading risk across investors with different risk appetites and return expectations.
Debt and Equity Financing in Real Estate Development
This, in a Canadian context, often relies on government-backed lending programs to shape the senior debt layer. CMHC’s MLI Select program, for example, offers insured financing with favourable terms for purpose-built rental projects that meet certain affordability, accessibility, or energy performance criteria. Access to a program like this can materially change what the senior debt layer looks like, which in turn affects how much equity a project needs and what return that equity has to target.
A Simple Example
A basic capital stack for a mid-size rental project might look something like this.
- Senior debt covering roughly 65 to 75 percent of total project cost, insured or conventional, repaid first and at the lowest rate.
- A smaller layer of mezzanine debt or preferred equity covering another 10 to 15 percent, repaid next at a higher fixed return.
- Common equity, usually sponsor and investor capital, covering the remaining balance, repaid last but entitled to the majority of profit above the other layers’ returns.
The exact split shifts from deal to deal based on the lender’s terms, the project’s risk profile, and how much return the sponsor and investors are targeting.
Where This Matters for Investors
Understanding where a specific investment sits in the stack matters more than the headline return being advertised. An investment described as targeting a strong return could sit anywhere from a relatively secure mezzanine position to a much riskier common equity position, and the underlying risk of each is very different even if the projected numbers look similar on paper. Working through what is a capital stack in real estate before committing capital is what keeps that distinction from getting lost in a pitch deck. This is part of why Black Creek Group is direct about where investor capital sits in a deal’s capital stack, rather than presenting a single blended return figure without context. Project Vespra is one example of a project structured with this layered approach in mind.
FAQs
What does “capital stack” mean in real estate?
It refers to the layered combination of debt and equity used to fund a real estate project, arranged in an order that determines who gets repaid first and who takes on the most risk.
What are the main layers of a typical capital stack?
Senior debt at the bottom, often followed by mezzanine debt or preferred equity in the middle, and common equity at the top.
Why does the order of the capital stack matter to investors?
Because it determines the sequence of repayment and the level of risk each investor is taking. A layer near the bottom is repaid first and takes less risk. A layer near the top is repaid last but usually keeps more of the upside.
How is a capital stack different for a development project versus buying an existing property?
A development deal often carries more equity risk during construction and lease-up, before there is any income to support debt. An existing, income-producing property can usually support a larger senior debt layer from the start, since it already has rent coming in.
What’s the simplest example of a capital stack?
Senior debt covering the majority of project cost, repaid first at the lowest rate, with common equity covering the rest, repaid last but keeping most of the profit if the project performs well. Many projects add a middle layer, such as mezzanine debt or preferred equity, between the two.
