Capital Stack: How It Works and What Every Real Estate Investor Should Know

The capital stack is the single most important concept to understand before putting money into any private real estate deal. It determines who gets paid first, who gets paid last, what return each position targets, and how risk is distributed across the people financing the property. This guide walks through each layer, explains how they interact during good performance and bad, and covers what the structure means for investors evaluating any specific deal.

The Direct Answer: What the Capital Stack Is

The capital stack is the ordered structure of all capital used to finance a real estate deal, from the lowest-risk, lowest-return position at the top to the highest-risk, highest-return position at the bottom.

Every dollar that funds a property sits somewhere in that stack. Senior debt sits at the top and gets paid first. Common equity sits at the bottom and gets paid last. Between them sit mezzanine debt and preferred equity, each with its own priority and return profile.

The stack isn't just about who gets paid. It defines who bears losses first when a deal underperforms, which is the part most investors underestimate.

The Four Layers of the Capital Stack

A typical commercial real estate capital stack has four layers, though not every deal uses all four.

Risk and return move in the same direction. Senior debt has the lowest expected return because it has the strongest claim on cash flow and collateral. Common equity has the highest expected return because it's the first layer to absorb losses.

Senior Debt

Senior debt is the mortgage or primary loan secured against the property. It typically represents 55% to 70% of the total capital in a commercial deal. The lender sits at the top of the stack with the strongest legal protection of any capital provider.

How senior debt gets paid

Monthly interest and principal payments come out of the property's net operating income before any other capital provider sees a dollar. If the property underperforms, the lender is still paid first. If the property is sold, proceeds pay off the senior debt in full before any other layer receives anything.

What happens when deals fail

If the property can't service the debt, the lender can foreclose and take possession. Everyone below senior debt, including every investor, can be wiped out completely. Senior debt is boring until things go wrong, and then it's the only position that reliably comes out whole.

Mezzanine Debt

Mezzanine debt sits between senior debt and equity. It's junior to the senior loan but senior to every equity position. Deals that use mezzanine typically use it for 10% to 20% of the stack, filling the gap between what senior lenders will provide and the equity the sponsor wants to raise.

How it's secured

Mezzanine debt is usually not secured by the property itself. Instead, it's secured by a pledge of the equity interests in the LLC that owns the property. If the borrower defaults, the mezz lender can foreclose on the LLC equity rather than the real estate.

That distinction matters. Senior lenders have to go through property foreclosure, which takes months. Mezzanine lenders can take control of the property-owning entity much faster, which is why they accept a lower position for higher return.

Return profile

Target returns on mezzanine typically run 9% to 13%, paid as current interest plus accrued interest paid at exit. Some mezz positions include a small equity participation, called a kicker, to sweeten the return.

Preferred Equity

Preferred equity is one of the most commonly misunderstood positions in the stack. It's technically equity, not debt, but it behaves more like debt in terms of payment priority and return expectations.

How preferred equity works

Preferred equity investors contribute capital in exchange for a fixed or capped preferred return, paid from cash flow before common sees anything. A typical structure might pay 10% to 15% annually, with any unpaid portion accruing until exit.

The investor sits behind all debt but ahead of common. They don't share in upside beyond their preferred return, which is the tradeoff for priority position.

Common Equity

Common equity sits at the bottom of the stack. It's the capital that owns the residual value of the deal after every other capital provider has been paid. It also bears losses first when the deal underperforms.

The upside case

Common equity investors share in property appreciation. If a deal is acquired for $10 million and sold three years later for $14 million after debt paydown, the $4 million gain flows almost entirely to common equity. That's where 15% to 25% target returns come from, and why common equity is the dominant position sponsors offer to LP investors.

The downside case

When deals underperform, common equity is the first position to lose value. If NOI drops and can't cover debt service, common dividends stop. If the property sells at a loss, debt gets paid first, preferred takes anything remaining, and common takes whatever's left. In a failed deal, that can be zero.

Preferred Equity vs Common Equity: The Key Distinction

Many investors don't distinguish clearly between these two positions, and the difference matters enormously for risk-adjusted returns.

A useful way to think about it: preferred equity is for investors who want higher yield than debt without the unlimited risk of common. Common equity is for investors who want full participation in upside and are willing to bear first-loss risk in exchange.

A Worked Example: What a Deal Looks Like

Consider a commercial real estate acquisition with a $10 million total capital requirement. A realistic stack might look like this.

If the property performs as underwritten and sells for $13 million three years later, debt service is paid through the hold, principal returns on debt and preferred equity at exit, and remaining gain flows to common equity.

If the property underperforms and sells for $8 million, debt is paid first ($7.5 million between senior and mezz), leaving $500,000. Preferred equity takes that $500,000, and common equity loses its entire $2 million. Senior debt is made whole, and everyone below it takes losses in order.

Why the Capital Stack Matters for Investors

Understanding where you sit in the stack is the difference between informed investing and gambling.

Risk positioning: a 15% target on common and 12% on preferred look similar on paper. The risk is not.

Return math: common returns are not guaranteed; preferred returns are contractual but capped.

Loss absorption: common absorbs the first dollar of losses. Debt holders see losses only after equity is wiped out.

Liquidity: senior lenders can force a sale; equity holders generally cannot.

Tax treatment: debt interest is tax-deductible to the entity; equity distributions flow through as pass-through income.

How Tokenization Affects the Capital Stack

Tokenization doesn't change the capital stack. Every legal structure, payment priority, and risk layer stays identical whether shares are issued as traditional LP units or digital security tokens.

What tokenization changes is access. Common equity positions in institutional deals historically required $100,000 to $250,000 minimums. Preferred equity was often available only to family offices and institutional LPs. Tokenization reduces these to $100 to $1,000 per token, opening positions that used to be structurally inaccessible.

The economic substance is unchanged. A tokenized common equity holder bears first-loss risk the same way a traditional LP does. What's different is ticket size, liquidity after lockup, and record-keeping quality.

What to Check Before Investing in Any Position

The full stack: what's the loan-to-value, and how much equity sits between you and the debt?

Your specific position: are you buying common equity, preferred equity, or something in between?

Payment priority: in a distressed scenario, how many dollars of losses must occur before your position is impaired?

Return structure: fixed preferred, participating preferred, or full common upside?

Debt terms: is the senior loan interest-only, and when does it mature relative to the hold period?

Sponsor capital: how much of the common equity is the sponsor contributing?

Where Node Proptech Fits

Node Proptech offerings are structured as common or preferred equity positions in SPVs that hold individual properties. Each offering document specifies which position a given Node represents, the target return, and payment priority relative to any debt.

Tokenization doesn't change the capital stack logic. Node investors own the same economic interests they would through a traditional syndication, with the same priority and payment order. What's different is the $100 ticket, the on-chain record, and the ability to exit through a regulated secondary venue after Rule 144 lockup.

Every Node offering includes full disclosure of the capital stack pre-investment, so investors can see exactly where they sit, how much leverage the deal uses, and what sits ahead of and behind them.

Final Word

The capital stack is the legal and economic map of a real estate deal. It tells you who holds power, who gets paid, and who bears the cost when things go sideways. Reading the stack accurately is a baseline skill, not an advanced one.

Every serious private real estate investment starts with understanding the stack. Everything else (sponsor, market, business plan, tax treatment) is secondary to knowing where you sit and what you're owed in each scenario.
