REITs Explained: Investing in Real Estate Without Buying Property

$1 Trillion in Assets and a 90% Payout Requirement

Real Estate Investment Trusts collectively own over $1 trillion in U.S. commercial real estate, from skyscrapers to cell towers to hospital buildings — and by federal law, they must distribute at least 90% of their taxable income to shareholders every year. That single rule shapes almost everything about how REITs behave as investments.

Congress created the REIT structure in 1960 specifically to give ordinary investors access to large-scale commercial real estate, assets that previously required either vast personal wealth or institutional backing. Today, roughly 145 million Americans hold REIT shares directly or through mutual funds and ETFs.

How a REIT Actually Works

A REIT is a company that owns, operates, or finances income-producing real estate. To qualify for special tax treatment under the Internal Revenue Code, a REIT must satisfy a dense checklist: at least 75% of its total assets must be real estate related, at least 75% of gross income must come from real estate sources, and it must have at least 100 shareholders with no five individuals owning more than 50% of shares. Meet those tests and the REIT pays no corporate income tax on distributed earnings — those taxes pass through to shareholders instead.

The result is a legal structure optimized for income extraction. Because retained earnings face double taxation, most REITs pay out far more than the legal minimum and rely on debt and equity markets rather than retained cash to fund acquisitions.

The Major REIT Categories

Equity REITs

Equity REITs own physical properties and collect rent. They represent roughly 90% of the REIT market by market capitalization. Subcategories include retail, office, industrial, residential, healthcare, data center, self-storage, and timber REITs — each with distinct demand drivers and risk profiles.

Mortgage REITs (mREITs)

Mortgage REITs invest in real estate debt rather than physical properties. They borrow at short-term rates and lend at long-term rates, earning the spread. This makes them acutely sensitive to interest rate movements and yield curve shape. When short rates spike — as they did in 2022 — mREIT net asset values can collapse with stunning speed.

Hybrid REITs

Hybrid REITs combine both equity and mortgage strategies. They are relatively uncommon and add complexity that often obscures risk.

REIT Type	Income Source	Primary Risk	Typical Yield Range
Equity REIT	Rental income	Vacancy, cap rate expansion	2–6%
Mortgage REIT	Interest spread	Interest rate volatility	8–14%
Hybrid REIT	Both	Compounded exposure	5–10%

Key Metrics for Evaluating REITs

Applying standard price-to-earnings analysis to REITs is misleading because accounting depreciation — a non-cash charge — dramatically reduces reported net income even as a building appreciates in real-market value. Analysts instead use Funds From Operations (FFO), which adds back depreciation and amortization, and Adjusted FFO (AFFO), which further adjusts for recurring capital expenditures required to maintain properties.

FFO per share: The baseline earnings metric for REIT comparison
AFFO per share: More conservative; subtracts maintenance capex and straight-lining of rents
Net Asset Value (NAV): Appraised property value minus liabilities; premium or discount to NAV signals relative valuation
Debt-to-EBITDA: REITs carry more leverage than typical equities; 5–7x is common, above 8x warrants scrutiny
Occupancy rate: Vacancy directly translates to lost revenue with fixed operating costs remaining

Tax Treatment of REIT Distributions

REIT dividends are mostly taxed as ordinary income at the investor's marginal rate — not at the lower qualified dividend rate that applies to most corporate dividends. This makes REITs substantially less tax-efficient in taxable accounts than in IRAs or 401(k)s, where distributions accumulate without current-year taxation. The Tax Cuts and Jobs Act of 2017 added a 20% deduction for pass-through income, which reduces the effective tax rate on REIT dividends for many investors, but the math still favors holding REITs in tax-advantaged accounts.

Distribution Component	Tax Treatment	Notes
Ordinary income	Marginal income tax rate	Most common; reduced by 20% QBI deduction
Qualified dividends	0–20% preferential rate	Only when REIT receives qualified dividend income
Return of capital	Deferred; reduces cost basis	Triggers capital gains when shares sold
Capital gains distributions	Long-term capital gains rate	When REIT sells appreciated properties

Sector Spotlight: Data Centers and Cell Towers

Not all real estate is bricks and mortar. Data center REITs like Equinix and Digital Realty own the physical infrastructure that hosts cloud computing. Cell tower REITs like American Tower and Crown Castle own the steel structures that carry wireless signals. Both sectors benefit from contracts with creditworthy tenants on long-term leases with built-in escalators — and both have dramatically outperformed traditional property sectors over the past decade because digital infrastructure demand is structurally growing rather than cyclical.

Risks Worth Understanding

Rising interest rates are the canonical REIT risk: higher rates increase borrowing costs, compress cap rate spreads, and make REIT dividends less attractive relative to bonds. The 2022 rate cycle cut the REIT index by roughly 25% from peak to trough. Leverage amplifies every downturn. Sector-specific risks are significant: office REITs face structural headwinds from remote work, retail REITs from e-commerce, and healthcare REITs from reimbursement policy changes.

Interest rate risk: Higher rates compress valuations and raise refinancing costs
Concentration risk: Single-sector REITs lose diversification when their niche suffers
Dilution risk: REITs that can't retain capital frequently issue new equity, diluting existing shareholders
Management quality: Capital allocation decisions in acquisitions have enormous long-run impact
