Key Takeaways
- The discount rate represents an investor's required return and is built on the risk-free rate plus various risk premiums.
- The 10-year U.S. Treasury yield is the standard risk-free rate benchmark, averaging approximately 4.2% in 2024.
- Real estate discount rates include premiums for illiquidity (1–3%), market risk, and property-specific risk.
- Cap rates and discount rates differ: cap rates are single-period measures, while discount rates are used in multi-period DCF analysis.
- When income is expected to grow, the discount rate approximately equals the cap rate plus the growth rate.
The discount rate is the rate of return an investor requires to justify committing capital to a particular investment. It serves as the bridge between future cash flows and present value. Understanding how discount rates are constructed — and why they differ across asset classes — is essential for sound real estate analysis.
The Risk-Free Rate as Foundation
Every discount rate starts with the risk-free rate, typically represented by the yield on U.S. Treasury securities. The 10-year Treasury yield is the most common benchmark, averaging approximately 4.2% in 2024 according to the Federal Reserve. This rate represents the return available with virtually zero default risk and serves as the floor for all other required returns.
The risk-free rate itself has two components: the real risk-free rate (compensation for deferring consumption, historically around 1–2%) and expected inflation. When inflation expectations rise, Treasury yields rise with them, pushing up discount rates across all asset classes — including real estate.

Building Up the Required Return
Investors add risk premiums to the risk-free rate to arrive at a required return. The build-up method is widely used in real estate: Required Return = Risk-Free Rate + Equity Risk Premium + Illiquidity Premium + Property-Specific Risk Premium. The equity risk premium for U.S. stocks has averaged 5.5–6.0% over the period 1926–2023 according to Ibbotson/Morningstar data. Real estate typically commands an additional illiquidity premium of 1–3% because properties cannot be sold as quickly as publicly traded securities.
Property-specific premiums vary by asset class, location, tenant quality, and lease structure. A Class A office building in Manhattan with long-term investment-grade tenants might carry a total discount rate of 7–8%, while a value-add multifamily property in a secondary market could require 10–13%. Institutional investors such as pension funds commonly target unlevered returns of 7–9% for core real estate.

Cap Rates, Discount Rates, and Yield Rates
Capitalization rates (cap rates) and discount rates are related but distinct concepts. A cap rate is a single-period return measure: Cap Rate = NOI / Property Value. A discount rate is used in multi-period discounted cash flow (DCF) analysis. For a property with stable, non-growing income, the cap rate equals the discount rate. When income is expected to grow, the discount rate equals the cap rate plus the expected growth rate (Gordon Growth Model: r = Cap Rate + g).
As of mid-2024, NCREIF reported average cap rates of 4.5% for industrial, 5.0% for multifamily, 6.5% for office, and 6.0% for retail properties. These differences reflect varying risk levels: industrial benefits from e-commerce tailwinds and strong tenant demand, while office faces headwinds from remote work. Understanding this relationship helps investors avoid the mistake of comparing cap rates across fundamentally different risk profiles.

Common Mistakes to Avoid
Applying the same discount rate to all property types
Consequence: Overpaying for risky assets and underbidding on stable ones, because different property types carry different risk premiums.
Correction: Calibrate the discount rate to the specific property type, market, tenant profile, and lease structure. Office assets carry different risk premiums than industrial or multifamily.
Confusing the cap rate with the discount rate
Consequence: Underestimating required returns when income is expected to grow, since the cap rate alone does not capture future growth expectations.
Correction: Use the cap rate for quick single-year comparisons and the discount rate for multi-year DCF analysis. Remember: Discount Rate ≈ Cap Rate + Growth Rate.
Using a stale risk-free rate instead of the current yield
Consequence: The discount rate may not reflect current market conditions, leading to mispriced investments.
Correction: Always use the current 10-year Treasury yield when constructing discount rates, and update the analysis if rates change materially before closing.
