What are the four ways to invest in real estate capital markets?
Classify the security you hold on two axes: equity versus debt, and publicly traded versus private. Equity participates in residual gains and losses. Debt has a contractual claim whose risk depends on its terms, seniority, and collateral.

Understand the numbers
A worked example, step by step
Compare four examples: shares of a listed equity REIT, a traded commercial mortgage-backed security (CMBS), a private property partnership interest, and a directly originated commercial mortgage.
This fixed teaching example is separate from your saved calculator inputs. Enter the assumptions above to reproduce it.
- Listed REIT shares: public equity. Traded CMBS: public debt.
- Private property partnership interest: private equity. Directly originated mortgage: private debt.
- Ask what you actually own. Shares of a mortgage REIT are equity in a company that invests in mortgages; the shares do not turn their holder into a mortgage lender.
Identify the claim first, then liquidity and control
What the result tells you
Public trading can make a position easier to sell, but liquidity varies and prices move. Private equity can offer negotiated governance, yet a passive limited partner may have little day-to-day control.
Assumptions to check
These categories are not risk ratings. Debt is not automatically safe, equity does not guarantee control, and listed securities do not always trade easily. Benchmarks also differ in leverage, valuation methods, and fees.
Try one change
Select each quadrant and explain who pays you, how you could exit, and what happens if the property underperforms.
