What Is a REIT?
A Real Estate Investment Trust (REIT) is a company that owns, operates, or finances income-producing real estate. Congress created the REIT structure in 1960 to let ordinary investors access large-scale commercial real estate — office buildings, shopping centers, hospitals, data centers, warehouses — the same way they access stocks. In exchange for special tax treatment, REITs must distribute at least 90% of their taxable income to shareholders as dividends each year.
This mandatory dividend requirement is what makes REITs stand out in any income portfolio. REIT dividend yields typically range from 3% to 8%, significantly above the S&P 500 average yield of around 1.5%. And because they own real physical assets that appreciate over time, REITs also offer capital appreciation potential on top of income.
How REITs Work
REITs pool capital from many investors to purchase and manage real estate portfolios that would be impossible for individuals to own. The REIT collects rent from tenants, covers operating expenses and debt service, then distributes the remaining income to shareholders as dividends. Publicly traded REITs (listed on stock exchanges like the NYSE) offer the same liquidity as any stock — you can buy and sell shares instantly at market prices, unlike physical real estate which takes months to sell.
There are also non-traded REITs (not listed on exchanges, sold through broker-dealers) and private REITs (for institutional investors). For individual investors, publicly traded REITs are almost always the better choice because of their liquidity, price transparency, and regulatory oversight.
Types of REITs
Equity REITs
The most common type — equity REITs own and operate physical properties. Within equity REITs, there are dozens of sub-sectors: Residential REITs (apartment communities, manufactured housing, single-family rentals); Industrial REITs (warehouses, distribution centers, logistics facilities — massive demand from e-commerce growth); Office REITs (office buildings and business parks — facing headwinds from remote work trends); Retail REITs (shopping malls, strip centers, net lease properties — structurally challenged by e-commerce); Healthcare REITs (hospitals, medical office buildings, senior housing, skilled nursing facilities); Data Center REITs (facilities housing servers and networking equipment — one of the fastest-growing REIT sectors driven by cloud computing and AI demand); Self-Storage REITs (storage facilities — simple business model with low capital requirements and high margins); and Cell Tower REITs (American Tower, Crown Castle — own the towers that telecom companies lease for wireless infrastructure).
Mortgage REITs
Instead of owning properties, mortgage REITs invest in mortgage-backed securities and real estate loans. They profit from the spread between the interest they earn on mortgages and their borrowing costs. Mortgage REITs tend to have much higher yields (often 8-12%) but are far more volatile — they're essentially leveraged fixed-income investments that suffer heavily when interest rates rise. Most income investors are better served by equity REITs for their combination of income and real asset backing.
Key REIT Metrics
Funds From Operations (FFO)
Standard earnings per share (EPS) is a poor measure for REITs because it subtracts depreciation — a non-cash expense that doesn't reflect the actual economics of real estate ownership (properties typically appreciate, not depreciate). FFO adds back depreciation to net income to give a clearer picture of cash earnings. This is the primary valuation metric for REITs. Price-to-FFO (like P/E for regular stocks) is how REITs are valued. A P/FFO below 15x is generally attractive; above 25x is expensive. AFFO (Adjusted Funds From Operations) also subtracts recurring capital expenditures needed to maintain properties, giving an even more conservative cash flow measure.
Net Asset Value (NAV)
REITs can also be valued by their underlying real estate. NAV estimates the market value of all properties owned minus all debt. If a REIT trades at a significant discount to NAV, it may be undervalued. If it trades at a large premium, it may be expensive or overvalued. Real estate data companies like Green Street Advisors publish NAV estimates for publicly traded REITs.
Occupancy Rate
High occupancy is the lifeblood of a REIT's revenue. Vacancy reduces rental income while fixed costs (debt service, maintenance) remain. Look for REITs with occupancy rates above 90% across their portfolio. Declining occupancy is an early warning sign of deteriorating business conditions.
Dividend Coverage Ratio
FFO divided by dividends paid shows how safely a REIT covers its dividend. A coverage ratio above 1.2x (paying out less than 83% of FFO as dividends) is healthy and leaves room for dividend growth. Below 1.0x — paying out more than FFO — is unsustainable and often signals an upcoming dividend cut.
Best and Worst REIT Sectors Right Now
Strong tailwinds: Industrial/logistics REITs (Prologis, EastGroup) benefit from e-commerce growth and supply chain reshoring. Data center REITs (Equinix, Digital Realty) benefit from AI infrastructure buildout. Self-storage REITs (Public Storage, Extra Space) have demonstrated pricing power and recession resilience. Cell tower REITs (American Tower, SBA Communications) have long-term lease agreements with major telecoms providing predictable cash flows. Facing headwinds: Office REITs are under structural pressure from remote and hybrid work — vacancy rates in many major US cities remain elevated post-pandemic. Regional mall REITs face ongoing tenant concentration risk and traffic declines as department store anchors close.
How to Add REITs to Your Portfolio
REITs make sense as 5-15% of a diversified investment portfolio. The most practical approach: buy a low-cost REIT ETF for broad exposure — Vanguard Real Estate ETF (VNQ) covers the full US REIT market at 0.12% expense ratio; Schwab US REIT ETF (SCHH) at 0.07%. If you want targeted exposure to high-quality sectors, individual REITs like Prologis (industrial), Equinix (data centers), or Realty Income (net lease retail) are blue-chip choices with long dividend growth histories.
Tax note: REIT dividends are mostly ordinary income (not qualified dividends), taxed at higher rates. Hold REITs in tax-advantaged accounts (IRA, 401k) where possible to avoid the tax drag. In a taxable account, REITs may benefit from the 20% pass-through deduction available under current tax law.
Bottom Line
REITs democratize access to commercial real estate in a way that was impossible for most investors before 1960. They offer higher income than most stocks, real asset backing, and long-term inflation protection through rent escalation. The best REITs combine high-quality properties in growing markets, conservative balance sheets, and strong dividend growth histories. Avoid chasing high yields in struggling sectors (office, retail) and focus on the sub-sectors with structural growth tailwinds: industrial, data centers, and healthcare real estate.
