Capital Stack — at a glance

The capital stack is the layered structure of debt and equity financing that funds a real estate transaction. Each layer has a different position in the priority of payment, a different risk profile, and a different return expectation — from senior debt at the safest position with lowest returns, to common equity at the riskiest position with the highest upside.

Formula

How Capital Stack is calculated

Capital Stack (Top to Bottom): Senior Debt → Mezz Debt → Preferred Equity → Common Equity
Senior Debt
First-position mortgage. Safest, lowest cost (6–10%). Typically 50–70% of stack.
Mezz Debt
Subordinated debt secured by LLC interest. 11–16% cost. 5–15% of stack.
Preferred Equity
Priority equity with defined returns. 8–14% coupon. 5–20% of stack.
Common Equity
Residual ownership; gets paid last, captures upside. 15–30% of stack.
In depth

What Capital Stack actually means in practice

The capital stack determines both the financial structure and the risk distribution of a deal. Senior debt is the largest and safest layer — it gets paid first from cash flow and gets first claim on proceeds in default. Common equity is the smallest (but most levered) layer — it's last to be paid but captures all upside above the other layers' returns. Everything in between (mezz, pref) is structured to bridge the gap.

The structure each deal uses depends on the asset type, sponsor strategy, and risk tolerance. Stabilized core property might use just senior debt + sponsor equity. Value-add deals often add mezz to push leverage higher without diluting sponsor equity. Ground-up development typically uses the deepest stacks — senior construction + mezz + pref + common — because total capital needs are high relative to any single source.

Each layer's return reflects its risk position. Senior debt at first position with collateral protection prices at 6–10%. Mezz at second position with LLC interest pledge prices 11–16%. Pref equity with priority distributions but no security prices 8–14%. Common equity has no defined return but targets 14–25%+ IRR by capturing upside above all other layers.

Sophisticated sponsors think about the capital stack as a portfolio of capital sources, each with its own cost, terms, and execution risk. Optimizing the stack means finding the mix of leverage, mezz, and pref that maximizes sponsor returns at acceptable execution risk. Over-leveraging produces fragile deals; under-leveraging dilutes sponsor returns. The right answer is asset-, market-, and timing-specific.

Worked example

Worked example: capital stack on a $25M value-add deal

Total project cost$25,000,000
Senior bridge debt (65% LTC)$16,250,000 — SOFR + 350, IO
Mezz debt (12% LTC)$3,000,000 — 12.5% fixed, IO
Preferred equity (8% LTC)$2,000,000 — 10% pref + 25% upside
Common equity (15% LTC)$3,750,000
Total stack share
Senior65%
Mezz12%
Preferred equity8%
Common equity15%
Result: A typical value-add capital stack — 85% non-equity capital, 15% sponsor equity. Common equity captures most of the upside at exit.

Why it matters

The five things to remember about Capital Stack

Stack structure determines risk distribution and return capture.
Senior debt is safest + cheapest; common equity is riskiest + highest upside.
Each layer's return reflects its risk position in the stack.
Optimal stack varies by deal type, asset, and sponsor strategy.
Over-leveraged stacks produce fragile deals; under-leveraged dilute returns.

FAQ

Common questions about Capital Stack

What is the capital stack in real estate?

The layered structure of debt and equity financing that funds a real estate deal. From safest (senior debt) to riskiest (common equity), each layer has different priority, risk, and return.

What's the order of payment in the capital stack?

Senior debt is paid first (interest, then principal in default). Mezz second. Preferred equity third. Common equity is paid last from whatever remains.

Why do sponsors use multiple capital layers?

To optimize leverage without ceding too much equity to LP investors. Adding mezz and pref to senior debt lets sponsors do larger deals without diluting their equity stake or returns.

How does the capital stack affect sponsor returns?

More leverage (deeper stack) generally amplifies sponsor returns but increases execution risk. The optimal stack balances return amplification against fragility.

Who decides the capital stack structure?

The sponsor, in negotiation with each capital source. Senior lenders set their max LTV/LTC, mezz lenders set their max combined leverage, pref / common equity investors negotiate their return waterfalls. Sponsors quarterback the whole structure.
