How REITs Work: Real Estate Returns Without the Toilets
A 1960 law lets anyone own a slice of skyscrapers, warehouses, and cell towers through the stock market, on one condition: the profits must be paid out. Here is the machine, its math, and its quirks.
The Democratization Deal
Until 1960, owning commercial real estate required being rich enough to buy buildings. Then Congress created the REIT, the real estate investment trust, a company that owns income producing property and trades like any stock, built around a simple exchange, the REIT pays no corporate income tax, and in return it must distribute at least 90 percent of its taxable income to shareholders as dividends, hold most of its assets in real estate, and earn most of its income from it. The deal eliminated the double taxation that burdens ordinary corporations and turned real estate into something a college student can own for the price of one share, which is exactly what the law intended. Today the listed US REIT sector spans well over a trillion dollars in equity, and, crucially for anyone learning it, the word REIT covers wildly different businesses wearing one wrapper.
What Is Actually Inside the Wrapper
The mental model most people carry, office towers and malls, describes the sector\'s past. Modern REIT indexes are dominated by the economy\'s newer physical infrastructure, cell tower REITs leasing antenna space to carriers, the data center landlords our hottest trade article profiles, logistics warehouses serving e-commerce, self storage, apartments, medical facilities, and specialist niches from timberland to casinos. Each type is its own business with its own cycle, the office REITs lived the bifurcation our office reset describes, apartment REITs ride the shortage math of our multifamily piece, and tower and data center REITs trade like technology infrastructure. There are also mortgage REITs, a separate species entirely, they own property debt rather than property, run on leverage and rate spreads, and their double digit yields carry precisely the risk that phrase implies. Sector selection inside REITs matters more than the decision to own REITs at all.
A REIT is a wrapper, not an asset class. The wrapper guarantees the tax treatment and the payout. What is inside, towers, warehouses, offices, mortgages, determines everything else, which is why two REITs can sit at opposite ends of a year\'s performance table every single year.
The Math: FFO and the Growth Treadmill
Two mechanics make REIT analysis different from ordinary stocks. First, earnings are the wrong metric, real estate accounting charges depreciation, covered elsewhere on this site, against buildings that often appreciate, so REITs report funds from operations, FFO, net income with depreciation added back and property sale gains stripped out, and price to FFO plays the role P/E plays everywhere else, alongside net asset value, the market worth of the buildings minus debt, with REITs trading at premiums or discounts to NAV as the market\'s live opinion of private real estate pricing. Second, the payout rule creates a growth treadmill, a company distributing 90 percent of income retains almost nothing to reinvest, so REITs grow by continually issuing new shares and debt to buy buildings, which works beautifully when their stock trades above NAV, each share issued buys more building than it costs, and stalls when it trades below, a reflexive loop where the stock price partially determines the business\'s ability to grow. It also makes REITs rate sensitive twice over, higher rates raise their borrowing costs and compete with their dividend yields, the dynamic that made 2022 brutal for the sector and makes every Fed meeting a REIT event.
Where They Fit for an Investor
The practical case, sized honestly. REITs deliver the diversification and income of commercial real estate with daily liquidity and thousand dollar entry, historical long run returns competitive with equities, and inflation participation through the rent resets our multifamily article explains. The caveats, their dividends are taxed mostly as ordinary income, which argues for holding them inside the tax sheltered accounts our Roth IRA article covers, their daily prices inherit stock market volatility, real estate crashes and REIT crashes arrive on different calendars, and they are already inside every total market index fund, so a dedicated allocation is a deliberate overweight, defensible for income seekers, not mandatory for anyone. The professional\'s use is subtler, listed REIT prices reprice property values months before private appraisals admit anything, making the REIT market the best free leading indicator of where buildings are actually headed, the exact role it played through the office reset.
The Bottom Line
REITs trade corporate tax freedom for a 90 percent payout, wrapping every kind of income property in a liquid stock, analyzed through FFO and NAV rather than earnings, growing on a treadmill of perpetual capital raising, and swinging with interest rates by construction. Pick the property type before the ticker, hold them tax sheltered, and read their prices as the market\'s fastest opinion on real estate itself. Owning buildings without toilets is a genuinely good deal, provided you understand which buildings, and whose plumbing, you actually bought.
