What is Capital Stack?
The complete structure of debt and equity financing used to fund a real estate acquisition.
Definition
The capital stack represents the total financing structure of a real estate deal, arranged by seniority from most senior (lowest risk, lowest return) to most junior (highest risk, highest return). A typical syndication capital stack includes: senior debt (first mortgage), mezzanine debt (subordinated loan), preferred equity, and common equity (LP and GP contributions). Each layer has different rights, return profiles, and risk characteristics. Complex syndication deals may have multiple debt tranches, multiple equity classes, and hybrid instruments that blur the lines between debt and equity.
Example
A $30M multifamily acquisition might be financed with: $21M senior loan (70% LTV, 6.0%), $3M mezzanine loan (10%, 11.0%), $1M preferred equity (3.3%, 12% coupon), and $5M common equity (16.7%, split between LP and GP). Each layer is paid in order of seniority — senior debt first, then mezzanine, then preferred equity, then common equity splits through the waterfall.
Why It Matters for Syndication
The capital stack determines leverage, risk profile, and return potential for every participant in the deal. Modeling the interaction between multiple debt instruments and equity layers is one of the most complex tasks in syndication underwriting. Syndication Analyzer supports up to 3 concurrent loans with independent terms, amortization schedules, and maturity dates — alongside multi-class equity structures.
