REIT Investing Guide: How Real Estate Investment Trusts Work and Why They Belong in Your Portfolio

Real estate has produced more American millionaires than almost any other asset class, but buying a rental property means finding tenants, fixing what breaks, and tying up six figures in one illiquid address. A REIT lets you own the same kind of income-producing real estate - apartment towers, warehouses, hospitals, shopping centers - for the price of one share, with a dividend check that shows up whether or not you ever answer a maintenance call. Here is how the structure actually works, and what separates a well-run REIT from a value trap yielding double digits for a reason.

What a REIT Actually Is

A Real Estate Investment Trust is a company that owns - and in most cases actively manages - a portfolio of income-producing real estate, and whose shares trade on a stock exchange exactly like any other public company. Congress created the REIT structure in 1960 specifically to let ordinary investors access commercial real estate the same way they access stocks: without the capital, expertise, or hassle of buying and operating a building directly.

What makes a REIT legally distinct from an ordinary real estate company is a trade-off written into the tax code. In exchange for avoiding corporate income tax - the tax a normal company pays on its profits before anything reaches shareholders - a REIT must meet a specific set of requirements:

• Distribute at least 90% of taxable income to shareholders annually as dividends
• Hold at least 75% of total assets in real estate, cash, or government securities
• Derive at least 75% of gross income from rents, mortgage interest, or real estate sales
• Have at least 100 shareholders, with no five or fewer shareholders owning more than 50% of shares

The 90% distribution rule is the one that matters most to an investor's experience owning the stock. It is the mechanical reason REITs pay dividend yields that are structurally higher than the average public company's - a typical business retains most of its profit to reinvest in growth or buy back stock, while a REIT is required to send nearly all of it back to shareholders every year, then usually raise fresh capital (debt or new share issuance) separately to fund acquisitions and development.

That trade-off defines the REIT investment case in one sentence: you are buying current income and a call on real estate appreciation, in exchange for slower reinvestment-driven growth than a typical operating company.

The Five Major REIT Property Sectors

"REIT" is not one investment - it is a legal structure applied across property types with very different tenants, lease structures, and economic drivers. Understanding which sector a REIT operates in matters more than almost any other single fact about it.

1. Retail REITs

Retail REITs own shopping centers, malls, and freestanding stores, collecting rent from tenants ranging from grocery-anchored strip centers to luxury mall retailers. The sector split sharply after the 2010s e-commerce shift: malls anchored by struggling department stores faced years of tenant bankruptcies and store closures, while grocery-anchored and necessity-based retail centers (pharmacies, discount stores, service tenants that online shopping cannot replace) held up far better because their tenants depend on foot traffic that e-commerce does not substitute for.

What to watch: tenant quality and diversification, exposure to department-store anchors versus necessity retail, and same-store sales growth at the tenant level, since a struggling tenant base eventually shows up as rent concessions or vacancies.

2. Residential REITs

Residential REITs own apartment communities (and in some cases single-family rental homes and manufactured housing communities), earning revenue from lease renewals and turnover in markets with strong population and job growth. Residential REITs benefit from short lease terms (typically 12 months) that let rents reset to market relatively quickly compared to other sectors - a meaningful advantage during inflationary periods, since rents can catch up to rising costs faster than a REIT locked into 10-year commercial leases.

What to watch: occupancy rates, same-store rent growth, and geographic exposure - Sun Belt markets with strong in-migration have generally posted stronger multi-year rent growth than slower-growing coastal metros, though supply of new apartment construction in fast-growing markets can pressure rents when a large wave of new units delivers at once.

3. Office REITs

Office REITs own corporate office buildings, and the sector has faced the most acute structural challenge of any REIT category since 2020: the shift to hybrid and remote work reduced the amount of office space many companies need, which has pressured occupancy and rents broadly across the sector, with older, lower-quality ("Class B" and "Class C") buildings in secondary locations affected far more severely than newer, amenity-rich "Class A" towers in prime locations that companies use to attract employees back to the office.

What to watch: lease expiration schedules (a wall of leases expiring in a weak leasing market is a real risk), the quality and location of the specific buildings owned, and whether occupancy is stabilizing or still declining - office has been the property type where "cheap" valuation and "value trap" have been hardest to tell apart in recent years.

4. Industrial and Logistics REITs

Industrial REITs own warehouses, distribution centers, and logistics facilities - the physical infrastructure behind e-commerce fulfillment and modern supply chains. This sector was the single biggest beneficiary of the shift to online shopping: every incremental dollar of e-commerce sales requires meaningfully more warehouse space than the same dollar of in-store retail sales, because online fulfillment requires holding and sorting inventory that a physical store customer would otherwise carry out the door themselves.

What to watch: rent growth on lease renewals (a strong signal of pricing power in a market), exposure to e-commerce versus traditional manufacturing tenants, and new supply - a wave of speculative warehouse construction can temporarily outpace demand in specific markets, pressuring rents even for a structurally strong sector.

5. Healthcare REITs

Healthcare REITs own medical office buildings, senior housing communities, skilled nursing facilities, and hospitals, leasing space to healthcare operators and, in senior housing, sometimes participating directly in operating economics rather than collecting a fixed rent check. The demographic tailwind is straightforward and durable: the aging U.S. population structurally increases demand for senior housing and medical office space over multi-decade horizons, though senior housing specifically carries more operating risk than a triple-net lease structure, since occupancy and staffing costs flow more directly into REIT-level results.

What to watch: the split between triple-net leased assets (predictable, bond-like income) and operating assets (more volatile, more upside), occupancy trends in senior housing, and government reimbursement policy exposure for skilled nursing operators.

Beyond these five, several specialized REIT categories have grown substantially: data center REITs (owning the physical infrastructure behind cloud computing and AI workloads), cell tower REITs (leasing space on communications infrastructure to wireless carriers), self-storage REITs, and casino/gaming REITs that own the real estate underlying casino operations under long-term net leases. Each behaves more like its own micro-sector than a subset of the five above, with different tenants and demand drivers entirely.

Equity REITs vs. Mortgage REITs

The single most important structural distinction in REIT investing - more important than property sector - is the split between equity REITs and mortgage REITs, because the two types earn money in fundamentally different ways and carry very different risk profiles.

Equity REITs own physical property directly and earn revenue from rent. This is what most people mean when they say "REIT," and it covers the five sectors above. An equity REIT's economics are relatively straightforward to understand: rent collected, minus operating expenses, financing costs, and depreciation, distributed to shareholders.

Mortgage REITs (mREITs) do not own physical property at all. Instead, they own mortgages and mortgage-backed securities, earning income from the spread between what they collect in interest on those loans and what they pay to borrow the money used to buy them - a business model that is functionally closer to a leveraged bond fund than to a landlord. Mortgage REITs typically use significant leverage (borrowing several dollars for every dollar of shareholder equity) to amplify that interest-rate spread into a meaningful return, which is also why mortgage REITs carry a materially different - and often higher - risk profile than equity REITs.

That leverage cuts both directions. In a stable or falling-rate environment with a healthy yield curve, mortgage REITs can generate very high dividend yields off a relatively small equity base. But mortgage REITs are acutely exposed to interest rate volatility, credit spread widening, and - critically - to a flat or inverted yield curve, where the cost of short-term borrowing rises toward or above the yield on the longer-term mortgages the REIT holds, compressing or eliminating the spread the entire business model depends on. Mortgage REIT dividend cuts during periods of rate volatility have historically been sharper and more frequent than equity REIT dividend cuts.

For most investors building long-term real estate exposure, equity REITs are the more intuitive and generally steadier building block. Mortgage REITs can play a role for income-focused investors specifically seeking high current yield and who understand the added leverage and rate-spread risk they are taking on - they are a different asset, not a higher-yielding version of the same asset.

How to Value a REIT: FFO and AFFO Instead of EPS

Valuing a REIT using standard earnings per share is one of the most common mistakes new REIT investors make, because GAAP net income systematically understates a REIT's real economic profitability - and the reason is a single accounting line item: depreciation.

Accounting rules require every company to depreciate its physical assets over time, expensing a portion of the building's value each year as if it were steadily wearing out. For most industries this is a reasonable approximation of reality - a factory's machinery does wear out. But well-located, well-maintained commercial real estate has often historically appreciated over long holding periods rather than declined in value, which means the depreciation expense on a REIT's income statement can be a large, entirely non-cash charge that has little relationship to what is actually happening to the value of the underlying property.

Funds From Operations (FFO) is the REIT industry's standard adjustment for this distortion. The formula, defined by the National Association of Real Estate Investment Trusts (Nareit):

code-highlight
FFO = Net Income
    + Real Estate Depreciation & Amortization
    - Gains on Property Sales
    + Losses on Property Sales

Adding back depreciation removes the non-cash distortion, and removing gains and losses on property sales strips out one-time transactions that do not represent the REIT's ongoing, recurring operating performance.

Adjusted FFO (AFFO) goes a step further, subtracting recurring capital expenditures required to maintain the properties (roof replacements, HVAC systems, tenant improvements) - expenses that are real and recurring even though FFO does not capture them. AFFO is generally considered the closest REIT equivalent to free cash flow, and it is the figure most commonly used to assess whether a REIT's dividend is actually well-covered by the cash the business generates.

The metrics that replace P/E and dividend payout ratio for REITs:

A REIT trading at what looks like an expensive P/E ratio based on GAAP net income can be reasonably valued - or even cheap - on a Price/FFO basis, because the depreciation charge dragging down net income is not a real cash cost. Conversely, a REIT paying out well over 100% of AFFO as dividends is a warning sign regardless of how attractive the headline yield looks, since it implies the dividend is being funded by something other than the cash the properties are actually generating - new debt, asset sales, or dilutive share issuance - none of which is sustainable indefinitely.

Why REITs Are So Sensitive to Interest Rates

No macro variable moves REIT prices as consistently as the direction of interest rates, and understanding why requires separating three distinct mechanisms that all point the same direction when rates rise.

1. Financing costs. REITs typically carry meaningful debt to finance property acquisitions and development, and both new borrowing and the refinancing of maturing debt become more expensive as rates rise. A REIT with a large slate of debt maturing during a high-rate period faces a real earnings headwind simply from refinancing at a higher cost than the loan it is replacing.

2. Yield competition. REITs are widely held by income-focused investors specifically for their dividend yield, and that yield does not exist in a vacuum - it competes with the yield available on investment-grade corporate bonds, Treasury bonds, and even cash equivalents like money market funds. When those "safer" yields rise, a REIT's dividend yield needs to stay competitive to hold investor capital, which typically happens through a falling stock price (since the dividend itself does not usually change quickly) rather than a rising payout.

3. Cap rate expansion. Commercial real estate is commonly valued using a capitalization rate ("cap rate") - the ratio of a property's annual net operating income to its market value. Cap rates tend to move with the broader interest rate environment over time, since real estate competes with bonds as a yield-generating asset class for the same institutional capital. When rates rise, cap rates have historically tended to follow (with a lag), which mechanically implies a lower valuation for a given stream of rental income - the same rent, capitalized at a higher rate, is worth less.

This dynamic played out clearly during the aggressive rate-hiking cycle of 2022, when REITs as a sector fell sharply even though rental income and occupancy at the property level, in most sectors, remained healthy - the pressure was almost entirely a valuation and financing-cost story rather than an operating-fundamentals story, illustrating how much of REIT price action can be macro-driven independent of what is actually happening inside the buildings.

None of this means REITs are doomed to underperform in every rising-rate environment. Strong rent growth, high occupancy, and low leverage can offset rate pressure - and REIT sectors with short lease durations (residential, in particular) can reprice rents upward faster than sectors locked into long fixed-rate leases, partially offsetting the financing-cost headwind with organic income growth. But as a starting framework, rate direction is one of the most reliable single variables for understanding REIT sector performance.

REIT ETFs vs. Individual REITs

Building REIT exposure comes down to a choice between a diversified fund and a portfolio of individually selected companies - and the right answer depends on how much sector-specific conviction an investor has.

Broad REIT ETFs (such as VNQ, SCHH, and IYR) hold dozens to well over a hundred REITs spanning every major property sector in a single trade, providing instant diversification against the single biggest risk in REIT investing: a concentrated bet on one property type or one overleveraged company going wrong at the same time the sector as a whole is under pressure. A broad ETF also removes the research burden of evaluating individual balance sheets, lease schedules, and management teams.

Individual REITs let an investor express a specific, researched view - overweighting industrial/logistics REITs on an e-commerce and supply-chain-reshoring thesis, favoring residential REITs in high-growth Sun Belt markets, or deliberately avoiding office REITs given the sector's structural post-2020 headwinds. That precision comes at the cost of concentration risk: a single company's leverage, tenant concentration, or management missteps can meaningfully affect returns in a way a diversified fund smooths out.

Sector-specific REIT ETFs occupy a middle ground - funds concentrated in a single property type (industrial, data center, residential) let an investor take a targeted sector bet with the diversification benefit of holding multiple companies within that sector rather than a single name.

A common approach many REIT investors land on: a core, low-cost broad REIT ETF position for baseline diversified real estate exposure, supplemented with a small number of individually selected REITs in sectors where the investor has done the underlying research and holds a specific, higher-conviction view.

The Tax Treatment of REIT Dividends

REIT dividends are taxed differently from a typical stock's dividend, and the distinction matters enough to affect where an investor chooses to hold REIT shares.

Most corporate dividends qualify for the lower qualified dividend tax rate (the same preferential rate as long-term capital gains) because the underlying profit was already taxed once at the corporate level before being distributed - the lower individual rate exists specifically to avoid taxing that income twice. A REIT, by design, pays no corporate income tax on the income it distributes, so that justification for a discounted rate does not apply. As a result, the majority of a REIT distribution is typically taxed as ordinary income at the investor's regular marginal tax rate - which can be substantially higher than the qualified dividend rate for investors in higher tax brackets.

A REIT distribution reported on Form 1099-DIV commonly breaks into three components:

Because of this ordinary-income tax treatment, many investors deliberately hold REITs inside tax-advantaged accounts (a 401(k), traditional or Roth IRA) rather than a taxable brokerage account, deferring or eliminating the tax drag entirely depending on account type - a meaningful, and easily overlooked, portfolio construction decision for anyone building significant REIT exposure. It is worth noting the 2017 tax law introduced a qualified business income deduction that can reduce the effective rate on the ordinary-income portion of REIT dividends for many investors, though the specific benefit depends on individual tax circumstances and is worth confirming with a tax professional rather than assuming it applies uniformly.

Screening for REITs: The Filters That Actually Matter

Because REIT sectors behave so differently from one another, a REIT-specific screen should go beyond the generic valuation filters used for the broader market.

FFO yield (FFO per share ÷ share price). The REIT equivalent of an earnings yield, and a starting point for relative valuation - a REIT trading at a high FFO yield relative to sector peers and its own history may be cheap, though it is worth checking why before assuming it is a bargain rather than a business under real fundamental pressure.

Occupancy rate. A direct read on demand for the REIT's specific properties. A REIT with occupancy meaningfully below sector peers, or declining over several quarters, is signaling either weaker-quality assets, weaker-quality tenants, or a market-specific supply/demand imbalance - occupancy trend is frequently the earliest visible signal of trouble, well before it shows up in FFO.

Debt levels and maturity schedule. Because REITs are structurally leveraged and required to pay out nearly all their income rather than retain cash, debt management is a genuinely bigger determinant of REIT survival through a downturn than for the average operating company. Screen for debt-to-EBITDA relative to sector peers, and check whether a large share of debt is maturing during a period when refinancing could be expensive.

Dividend coverage (Dividend / AFFO). A payout ratio meaningfully above 100% of AFFO is a warning that the dividend is not fully funded by recurring cash flow - worth investigating before treating a high headline yield as free money.

Same-store rent growth. Comparing rent growth on the same set of properties year over year isolates organic pricing power from growth that comes purely from acquiring new buildings, giving a cleaner read on whether the underlying portfolio is actually strengthening.

Common REIT Investing Mistakes

Chasing the highest headline yield without checking the payout ratio. A REIT yielding well above its sector peers is often signaling elevated risk that the market has already priced in - an unsustainable payout ratio, deteriorating occupancy, or excessive leverage - rather than simply being a bargain. High yield paired with a payout ratio well over 100% of AFFO is a dividend cut waiting for a catalyst, not a discount.

Valuing a REIT on P/E instead of P/FFO. As covered above, GAAP earnings understate REIT profitability because of non-cash depreciation. A REIT that looks expensive on a P/E basis can be reasonably or even cheaply valued on Price/FFO - using the wrong metric can screen out perfectly healthy REITs and screen in ones that are actually overvalued.

Ignoring lease expiration schedules, especially in office. A REIT with a large share of leases expiring during a weak leasing environment faces real re-leasing risk that will not show up in trailing financial results - it shows up in the forward lease schedule, which most REITs disclose in quarterly filings and investor presentations.

Treating "REIT" as one homogeneous asset class. Office and industrial REITs have faced almost opposite fundamental trends since 2020 - one structurally pressured by remote work, the other structurally boosted by e-commerce. A portfolio-level view of "REIT exposure" without a sector breakdown can mask very different risk profiles hiding under the same label.

Holding REITs in a taxable account without considering the tax treatment. Because most REIT income is taxed as ordinary income rather than at the qualified dividend rate, the after-tax return of the same REIT can differ meaningfully depending on whether it is held in a taxable account or a tax-advantaged retirement account.
