Building Your Capital Stack

Expanding a real estate portfolio requires a strategic approach to financing, and a well-structured capital stack is key to making it happen. The capital stack represents the financial structure of a commercial real estate deal, detailing the various sources of debt and equity used to fund the acquisition, development, and management of a property.

Understanding how the capital stack is structured can help investors assess risk, optimize returns, and secure the right mix of funding for their projects.

The Structure of the Capital Stack

A capital stack is often visualized as a layered structure, with each level representing a different type of financing. These layers indicate the priority of payment, risk exposure, and potential return for investors. Generally, the capital stack is composed of four primary layers: common equity, preferred equity, mezzanine debt, and senior debt. The lower the position in the stack, the lower the risk—but also the lower the return.

Common Equity – The Highest Risk, Highest Reward

At the top of the capital stack is common equity, where the primary investors and owners hold their stake in the property. This group takes on the most risk, as they are the last to receive payments from cash flow or property sales. However, common equity investors also have the highest earning potential through property appreciation and rental income.

Most commercial real estate investments are structured under a holding or management company, which oversees the property’s operations, leasing strategy, and overall business plan. The strength of the common equity partners is critical in attracting additional investors and lenders to the deal.

Preferred Equity – A Balanced Approach

Preferred equity sits just below common equity in the stack. Investors in this tier take on less risk than common equity holders, as they have a structured return and repayment priority. Preferred equity often operates like a loan, paying a fixed or variable return over a specified period. In some cases, if the project encounters financial distress, preferred equity investors may have the right to convert their stake into common equity or even assume control of the property.

Mezzanine Debt – Bridging the Gap

Mezzanine debt is a hybrid financing option that blends characteristics of both debt and equity. It sits between preferred equity and senior debt, offering investors higher returns than traditional debt but with greater security than equity positions.

Lenders providing mezzanine debt often charge higher interest rates than senior lenders, as their repayment priority is lower. However, this type of financing can be crucial for investors looking to bridge the gap between available senior debt and required equity. In some cases, mezzanine debt agreements include the option to convert a portion of the loan into equity, allowing lenders to share in the project’s upside potential.

Senior Debt – The Foundation of the Stack

At the base of the capital stack is senior debt, which represents the safest and most stable form of financing. Senior debt holders, typically banks or institutional lenders, are the first to be repaid in the event of a property sale or refinancing. Because of their lower risk exposure, senior lenders offer the most favorable interest rates.

Lenders at this level focus heavily on Debt Service Coverage Ratio (DSCR) when determining loan eligibility. DSCR measures a property’s ability to generate sufficient income to cover its debt obligations, ensuring that the investment remains financially viable.

The Purpose of the Capital Stack

A well-balanced capital stack benefits all parties involved by minimizing risk and maximizing returns. Investors at each level of the stack play a specific role in funding the project while protecting their financial interests.

When structured effectively, the capital stack allows investors to:

  • Leverage multiple financing sources to optimize returns
  • Mitigate risk by diversifying funding commitments
  • Attract additional investment partners by creating a clear financial structure
  • Ensure stability and long-term profitability for the property

Final Thoughts

Building an effective capital stack is a critical component of any successful commercial real estate investment. Understanding the different layers of financing—from common equity to senior debt—helps investors structure deals that attract capital, mitigate risk, and maximize profitability.
