Direct Answer
Real estate investment trusts (REITs) own, operate, or finance income-producing real estate and must distribute at least 90% of taxable income as dividends to maintain their tax-advantaged status. The REIT structure means investors effectively own real estate portfolios with stock market liquidity. REITs are categorized by property type: industrial (Prologis, Duke Realty), data centers (Equinix, Digital Realty), residential (AvalonBay, Equity Residential), retail (Simon Property Group, Realty Income), healthcare (Welltower, Ventas), self-storage (Public Storage, Extra Space), and office (Boston Properties). Investors analyze REITs on funds from operations (FFO), net operating income (NOI), cap rates, and dividend sustainability rather than traditional earnings metrics.
REIT Structure, Tax Status, and Property Types
REITs were created by Congress in 1960 to allow individual investors to access large-scale real estate portfolios with the liquidity of a publicly traded stock. To qualify for REIT status (and the resulting pass-through of income without corporate-level tax), a company must meet several requirements:
- At least 75% of total assets must be in real estate, cash, or U.S. government securities
- At least 75% of gross income must come from rents, mortgage interest, or gains from real estate sales
- At least 90% of taxable income must be distributed to shareholders as dividends
- At least 100 shareholders after the first year, with no five individuals owning more than 50% of shares
The 90% distribution requirement means REITs retain little cash for reinvestment and must access capital markets (equity or debt) for growth. This makes REITs more interest rate sensitive than typical operating companies -- they are essentially levered real estate portfolios, and rising rates both increase borrowing costs and reduce the relative attractiveness of REIT dividend yields compared to bond yields.
REIT property types include:
Industrial: Warehouse, distribution, and logistics facilities. Prologis is the dominant global industrial REIT. Demand is driven by e-commerce fulfillment (Amazon, UPS, FedEx), last-mile delivery, and supply chain restructuring. Industrial was the best-performing property type from 2015-2022 as e-commerce demand drove record rent growth and occupancy.
Data centers: Equinix, Digital Realty, and Iron Mountain operate large colocation and hyperscale data center facilities. Demand is driven by cloud computing growth (AWS, Azure, Google Cloud) and AI workload expansion. Data centers have longer-than-average lease terms (10-20 years for hyperscale), high switching costs, and significant barriers to entry from power and land constraints.
Residential: Apartment REITs (AvalonBay, Equity Residential, Camden Property, NMI Holdings) focus on urban and suburban multifamily. Single-family rental REITs (Invitation Homes, AMH) own and rent single-family homes. Demand is driven by household formation, affordability dynamics (high home prices push renters from owning), and migration trends to Sun Belt markets.
Retail: Ranges from mall-anchor REITs (Simon Property Group, Macerich) to net lease (Realty Income, NNN REIT) to strip centers (Regency Centers, Kimco). Net lease REITs own freestanding single-tenant properties leased to retailers on long-term leases (10-25 years) where the tenant pays property taxes, insurance, and maintenance in addition to base rent, resulting in highly predictable income streams.
Healthcare: Senior housing, medical office buildings, skilled nursing facilities, and life science campuses. Welltower, Ventas, and Healthpeak own portfolios that benefit from aging demographics (senior housing demand) and growing healthcare real estate demand (medical office, life science).
Self-storage: Public Storage, Extra Space Storage, and CubeSmart operate self-storage facilities with very high operating leverage (low labor per square foot), no long-term leases (month-to-month tenants), and high barriers to new supply in urban markets. Self-storage has historically been one of the most resilient real estate sectors in recessions because demand comes from life events (moving, downsizing) that continue regardless of economic conditions.
Funds From Operations and REIT Earnings Metrics
Traditional GAAP earnings metrics are misleading for REITs because depreciation is a large non-cash charge that reduces net income even when the underlying real estate is appreciating in value. REIT investors use funds from operations (FFO) and adjusted FFO (AFFO) instead:
FFO = Net Income + Depreciation and Amortization - Gains on Property Sales
FFO adds back real estate depreciation (which is a paper charge, not an economic cost for appreciating properties) and excludes gains on property sales (which are non-recurring). It is the REIT industry's primary earnings metric, defined by Nareit (the National Association of Real Estate Investment Trusts). FFO per share is the REIT equivalent of EPS.
AFFO (Adjusted FFO) is a further refinement that subtracts recurring capital expenditures required to maintain existing properties (tenant improvements, leasing commissions, maintenance capex). AFFO better represents the cash available for distribution to shareholders. Different REITs calculate AFFO differently; investors should read the definition in earnings releases carefully.
Net operating income (NOI) is property-level income before debt service: rental income minus operating expenses (property taxes, insurance, utilities, maintenance, management fees). NOI measures the operating performance of the real estate itself, separate from how the REIT is financed. Same-store NOI growth (NOI growth from properties owned in both periods) is the organic growth metric, analogous to same-store sales for retailers.
Cap rate (capitalization rate) measures property valuation: NOI divided by the property value. A property generating $5M of NOI purchased at $100M has a 5% cap rate. Cap rates are the real estate equivalent of price-to-earnings ratios: lower cap rates indicate higher valuations (investors accept lower current income for growth or quality). Cap rates spread over Treasury bonds matters: when Treasury yields rise, cap rates typically follow, compressing real estate values.
Key Metrics to Track
| Metric | What It Measures | Benchmark Context |
|---|---|---|
| FFO Per Share Growth | Primary earnings metric for REITs; analogous to EPS growth | Best-in-class: 5-10% annual FFO/share growth; compare to dividend growth |
| AFFO Payout Ratio | Dividends paid / AFFO; measures dividend sustainability | Below 85% is sustainable; above 95% leaves little retained cash; watch trend |
| Same-Store NOI Growth | NOI growth from properties owned in both periods; organic growth measure | Normal: 2-5%; strong rental market: 5-10%; negative = operating problems or rent roll declining |
| Occupancy Rate | Leased percentage of available space; demand signal | Industrial/data center: 95-99%; office: 80-90%; retail: 92-96%; multifamily: 93-97% |
| Lease Expiration Schedule | Percentage of leases expiring each year; roll risk | Higher near-term expirations = roll risk if market rents have fallen; opportunity if rents have risen |
| Net Debt / EBITDA | Leverage measure for REITs; EBITDA proxy is usually NOI | Well-capitalized REITs: 4-6x; higher leverage (7-10x) adds interest rate risk and refinancing risk |
| Debt Maturity Profile | When existing debt matures; refinancing risk assessment | Long duration debt (5-10 year maturities) reduces near-term refinancing risk at higher rates |
| Price / FFO Multiple | Stock price / FFO per share; REIT valuation metric analogous to P/E | Industrial/data center: 25-40x FFO; net lease: 15-20x; office: 8-12x; reflects growth expectations |
Interest Rate Sensitivity and Capital Structure
REITs are among the most interest rate-sensitive sectors in the equity market. This sensitivity has two components:
Direct financial sensitivity: REITs carry significant debt (typically 30-50% of total capitalization). Rising interest rates increase the cost of refinancing maturing debt, compressing FFO per share and reducing dividend coverage. A REIT with $10B of debt and an average cost of 3.5% that must refinance at 5.5% faces $200M of additional annual interest expense. The impact depends on the maturity schedule -- REITs with longer-duration fixed rate debt are insulated in the near term but face eventual refinancing at higher rates.
Relative valuation sensitivity: REITs are valued partly as yield instruments (high-dividend-paying stocks). When risk-free rates rise, the yield spread that investors demand over Treasuries may remain constant, requiring a higher dividend yield (lower stock price) to equilibrate. This creates a mechanical headwind: even if REIT fundamentals are unchanged, the stock price must fall to maintain the appropriate yield spread. This effect was the primary driver of REIT underperformance in 2022-2023 as the Federal Reserve raised rates rapidly.
Capital structure best practices: REITs manage interest rate risk through fixed-rate debt (locking in current rates for 5-10 years), staggered debt maturities (no concentration in any single year), and maintaining undrawn credit lines for liquidity. Investment-grade credit ratings are important for REITs because they determine access to the unsecured bond market, which is more flexible and cheaper than secured mortgage financing. A credit downgrade can significantly increase a REIT's cost of capital and limit growth opportunities.
Principal Risks
- Interest rate risk: Rising rates compress real estate cap rates and increase debt costs, creating a dual headwind to both valuations and earnings. The magnitude depends on the REIT's leverage, debt maturity profile, and the sensitivity of its specific property type to rate changes. Net lease REITs with long-term fixed leases are more rate sensitive than self-storage or residential REITs with short-term leases that can reset rents quickly.
- Property type obsolescence: Structural changes can permanently impair certain property types. Office demand declined sharply after COVID-19 as remote and hybrid work became mainstream, leaving many suburban office buildings with permanently impaired occupancy. Regional malls faced long-term decline from e-commerce before the pandemic accelerated tenant departures. Investors should assess whether a REIT's property type faces structural demand tailwinds or headwinds over a 5-10 year horizon.
- Tenant concentration and credit risk: REITs with high exposure to a few tenants face the risk that a major tenant bankruptcy or lease non-renewal materially impairs occupancy and NOI. Net lease REITs with exposure to retailers that have subsequently filed for bankruptcy (Rite Aid, Party City, Tuesday Morning) experienced significant occupancy and rent losses on those properties.
- Development risk: REITs that develop new properties rather than only acquiring existing ones take on construction and lease-up risk. Cost overruns, permitting delays, and demand disappointments at completion can impair expected returns. Development-heavy REITs trade at higher premiums during strong demand periods but face greater downside if market conditions shift during the multi-year development timeline.
- Equity dilution risk: REITs must distribute most taxable income and therefore fund growth through capital markets rather than retained earnings. In rising-rate environments, when REITs trade at significant discounts to estimated net asset value, issuing equity to fund acquisitions is dilutive to existing shareholders. Management teams that grow aggressively through dilutive equity issuance destroy per-share value even as total enterprise value grows.

FAQ
What is FFO and why do REITs use it instead of earnings per share?
Funds from operations (FFO) is the primary earnings metric for REITs because it adjusts for a significant accounting distortion in GAAP net income. Under GAAP, real estate assets are depreciated over their useful lives (27.5 years for residential, 39 years for commercial property), which creates a large non-cash expense that reduces net income. However, real estate often appreciates rather than depreciates in value over time, making this depreciation charge economically misleading. FFO adds back real estate depreciation to net income and also excludes gains on property sales, which are non-recurring and not reflective of ongoing operating performance. The result is a metric that better represents the cash generated by the REIT's real estate operations available for distribution to shareholders. Nareit (the National Association of Real Estate Investment Trusts) defined FFO in the 1990s to standardize reporting, though individual REITs still make various adjustments. Adjusted FFO (AFFO) is a further refinement that subtracts recurring maintenance capital expenditures, providing a still better estimate of true cash available for distributions.
How does a net lease REIT differ from a traditional REIT?
A net lease REIT (also called a triple net lease or NNN REIT) owns freestanding single-tenant commercial properties leased to retailers, restaurant chains, service businesses, and other operators under long-term leases (typically 10-25 years) where the tenant pays most or all of the property operating costs including taxes, insurance, and maintenance. The "triple net" in triple net lease refers to the tenant bearing these three categories of costs, leaving the landlord with a very predictable net rental income stream with minimal operating involvement. Realty Income is the largest publicly traded net lease REIT; NNN REIT (formerly National Retail Properties) and STORE Capital are others. Net lease REITs trade at a premium to traditional property types because of the predictability and lease length of their income. However, they are more sensitive to tenant credit quality (a bankrupt tenant stops paying rent and the landlord gets the property back) and interest rates (their long lease terms with modest rent bumps are similar to long-duration bonds, making them particularly sensitive to rising rates).
Why do REITs perform poorly when interest rates rise?
REITs underperform in rising interest rate environments for two interrelated reasons. First, REITs carry significant debt that must be refinanced at higher rates as it matures, increasing interest expense and reducing FFO per share. A REIT with $5 billion of debt at an average 3% coupon that refinances at 5.5% pays $125 million more annually in interest. Second, REITs are valued partly as yield instruments, with investors comparing their dividend yields to risk-free alternatives like Treasury bonds. When Treasury yields rise, the absolute yield that REITs must offer to remain competitive must also rise, which requires either dividend growth or lower stock prices. In the 2022-2023 rate cycle, the 10-year Treasury yield rose from under 1.5% to over 5%, and many REITs fell 20-40% in stock price as investors demanded higher dividend yields to maintain the spread over bonds. The impact was more severe for property types with long-duration income streams (net lease, data centers) and more modest for property types with short lease terms that could quickly reset rents higher.
What are cap rates and how do they relate to property values?
A capitalization rate (cap rate) is the ratio of a property's annual net operating income to its purchase price, expressing the income return on an investment. A property generating $1 million of NOI purchased for $20 million has a 5% cap rate. Cap rates are the real estate equivalent of an earnings yield (the inverse of a price-to-earnings ratio): lower cap rates indicate higher valuations (paying more per dollar of income), and higher cap rates indicate lower valuations. Cap rates are compared against the risk-free rate (typically the 10-year Treasury yield) to assess the income spread that real estate offers over government bonds. When Treasury yields rise, real estate cap rates typically follow (with some lag), compressing property values. For example, if a property has $5M of NOI and cap rates expand from 4% to 5.5%, the property's implied value falls from $125M ($5M / 4%) to $91M ($5M / 5.5%), a 27% decline. Cap rates vary significantly by property type and market: high-quality industrial and data center properties in primary markets trade at 4-5% cap rates; suburban office and secondary-market retail trade at 7-9% cap rates, reflecting the different growth and risk profiles.
How should investors evaluate REIT dividend sustainability?
REIT dividend sustainability is evaluated by comparing the dividend to AFFO (adjusted funds from operations) rather than to GAAP earnings. The AFFO payout ratio (dividends per share / AFFO per share) should be below approximately 85% to allow the REIT to retain some cash for maintenance and modest growth while still meeting the 90% taxable income distribution requirement. A payout ratio consistently above 95% leaves little margin; a ratio above 100% means the REIT is paying out more than it earns in AFFO and must either cut the dividend or raise equity to fund it. Beyond the payout ratio, dividend sustainability depends on the trajectory of NOI growth (a growing property portfolio can grow into an elevated payout ratio), the debt maturity profile (upcoming large maturities at higher rates may compress AFFO), and the quality of the tenant base (financially weak tenants create lease non-renewal or bankruptcy risk that would reduce NOI). REITs with long lease terms and contractual rent bumps (net lease, industrial) offer more dividend visibility than those with short lease terms and volatile demand (self-storage, lodging).
