Direct answer: A real estate investment trust (REIT) is a company that owns, operates, or finances income-producing real estate. To qualify as a REIT under U.S. tax law, the company must distribute at least 90% of taxable income to shareholders as dividends. This requirement means REITs typically pay high dividend yields but retain little cash for reinvestment. REITs provide exposure to real estate without the illiquidity of direct property ownership and trade on stock exchanges like equity shares.
Fact Sheet: Real Estate Investment Trusts (REITs)
Key Takeaways
- REITs must by law distribute at least 90% of taxable income as dividends; they often distribute 100% because REIT income is not subject to corporate tax (the income is passed through to shareholders, who pay individual income tax on it). REIT dividends are typically classified as ordinary income (taxed at marginal rates), not qualified dividends (taxed at lower capital gains rates).
- The major REIT categories: equity REITs (own and operate properties: office, retail, industrial, residential, healthcare, data centers, cell towers); mortgage REITs (invest in mortgage-backed securities or make mortgage loans); and hybrid REITs (both).
- Historically, U.S. equity REITs have provided returns similar to the broader stock market over long periods, with higher income component and somewhat lower correlation to U.S. large-cap stocks than many investors expect (correlation to S&P 500 is approximately 0.6 to 0.7 over rolling 5-year periods).
- The MSCI U.S. REIT Index represents approximately 99% of the U.S. REIT market; Vanguard Real Estate ETF (VNQ) tracks this index at 0.12% expense ratio. This is broadly accessible to all investors.
- REITs are tax-inefficient in taxable accounts (ordinary dividend income taxed at marginal rates); they belong in tax-deferred accounts (traditional IRA, 401(k)) rather than taxable accounts.
REIT Categories in Detail
Equity REIT subcategories show substantial return variation: data center REITs and cell tower REITs (Equinix, American Tower, Crown Castle) have been the strongest performers over the past decade, driven by technology infrastructure demand. Retail REITs (shopping malls: Simon Property Group, Macerich) underperformed significantly during the 2010s as e-commerce displaced physical retail. Healthcare REITs (senior housing, medical office, hospitals) have shown more stable income characteristics. Industrial REITs (logistics warehouses: Prologis) outperformed dramatically during the e-commerce growth period. Office REITs faced significant pressure following post-COVID work-from-home adoption. Investors in broad REIT index funds own all these subcategories in proportion to market cap.
Return and Correlation Characteristics
The FTSE Nareit All Equity REITs Index returned approximately 9.5% per year from 1994 to 2023 (total return including dividends), compared to approximately 10.5% for the S&P 500 over the same period. REIT returns include a substantial dividend component (yield of 3% to 5% historically) plus lower price appreciation than non-dividend-paying equities. REIT correlation to broad equity markets increases during market stress (all risk assets become more correlated in crises), which reduces their diversification value in the scenario where diversification is most needed. Interest rate sensitivity: REITs tend to underperform when interest rates rise sharply (their dividends become less attractive relative to fixed income, and borrowing costs for property acquisitions increase).
Tax Treatment
REIT dividends are classified as ordinary income for tax purposes (taxed at marginal income tax rates, up to 37%) unless the REIT pays a qualified dividend. Most REIT dividends are nonqualified. The 20% pass-through deduction (Section 199A) allows non-corporate taxpayers to deduct 20% of qualified REIT dividends, reducing the effective tax rate. In a taxable account, an investor in the 32% marginal bracket pays 32% minus 20% of 32% = 25.6% effective rate on REIT ordinary dividends. Compare to qualified stock dividends taxed at 15% to 20%; REITs are significantly less tax-efficient. Place REITs in a traditional IRA or 401(k) to defer taxation; place in a Roth account to eliminate it entirely.
REITs in a Portfolio
Academic research (Ibbotson, Mueller) finds that adding a 5% to 15% REIT allocation to a diversified stock/bond portfolio slightly improves risk-adjusted returns over long periods, driven by the diversification benefit and high income component. Practical portfolio construction: a broad REIT index fund (VNQ or SCHH) can serve as the REIT allocation within the equity portion of a portfolio. Some investors prefer REITs to provide real asset exposure as an inflation hedge; the evidence for REITs as an inflation hedge is mixed (rental income may keep pace with inflation, but REIT prices also reflect interest rates which move inversely to inflation sometimes). International REITs (VNQI) provide additional diversification beyond U.S. real estate markets.
Frequently Asked Questions
How are REITs different from directly owning real estate?
Direct real estate ownership provides leverage, tax advantages (depreciation, 1031 exchanges), and control over the property, at the cost of illiquidity, management burden, and concentration in a single property or geographic area. REITs provide liquidity (tradeable on exchanges), diversification across many properties, professional management, and income without management burden, but no leverage at the investor level, no depreciation tax shelter at the individual level, and no control over specific properties. REITs are appropriate for investors who want real estate exposure within a liquid, diversified investment portfolio; direct ownership is appropriate for investors who want to use leverage, the depreciation tax benefit, or 1031 exchanges.
What is a mortgage REIT and how does it differ from an equity REIT?
An equity REIT owns physical real estate properties and earns income from rents. A mortgage REIT (mREIT) invests in mortgages and mortgage-backed securities and earns income from interest. mREITs are highly interest-rate sensitive because they typically borrow short-term at lower rates and lend long-term at higher rates; when short-term rates rise sharply (as they did in 2022), the spread compresses and mREIT returns can be severely negative. mREITs are more volatile and less correlated to real estate fundamentals than equity REITs; they are better understood as leveraged fixed-income vehicles than real estate investments.
Does adding a REIT allocation improve a portfolio?
The evidence supports a modest allocation (5% to 15% of the equity portion) improving long-run risk-adjusted returns in historical data due to partial diversification from U.S. large-cap equities. The benefit is not guaranteed in every period; REITs underperformed significantly relative to the S&P 500 from 2010 to 2020. If you already hold a total stock market index fund, you already have REIT exposure (REITs represent approximately 3% to 4% of the total U.S. market capitalization); a separate REIT allocation is a tilt toward real estate, not the introduction of a new asset class.
