A REIT (real estate investment trust) is a publicly-listed company that owns or finances a portfolio of income-producing real estate and is required by IRC §856 to distribute at least 90% of its taxable income to shareholders each year as dividends. The structure gives any retail investor exposure to commercial real estate through a brokerage account, with daily liquidity, no accreditation requirement, and no minimum investment beyond the price of a single share.

For an accredited investor with capital to deploy, though, the more useful question is not what a REIT is in the abstract but where it actually fits in an allocation alongside the private multifamily syndication market. The two routes share an underlying asset class but produce very different outcomes on the dimensions that matter most to long-duration capital: how the income is taxed, how the principal value behaves through stock-market drawdowns, and how much of the return is structurally captured by the investor versus consumed by the vehicle.

This guide walks through what a REIT actually is and how it works, the property categories REITs invest in, the IRS qualification rules, the three structural types, and where the REIT chassis genuinely makes sense for an investor relative to a direct private syndication position.

What's a REIT (Real Estate Investment Trust)?

A REIT pools capital from public shareholders to acquire, operate, and in some cases finance income-producing real estate, then returns the operating income to those shareholders through a dividend that has to clear the 90%-of-taxable-income threshold to keep the entity's REIT tax status. The wrapper has been around since the 1960 Real Estate Investment Trust Act, which Congress passed specifically to let retail investors access institutional-scale commercial real estate the way they could already access institutional stocks and bonds.

In practical terms a publicly-traded REIT looks and behaves like a stock. Shares are bought and sold on the NYSE or Nasdaq, prices reset every trading second based on what the market thinks of the company's portfolio and management, and the dividend yield is the headline return number most retail investors anchor on when they evaluate one. The annual dividend payout typically runs 3 to 5 percent in equity REITs and somewhat higher in mortgage REITs, with any additional return coming from share-price appreciation if the market revalues the portfolio over the holding period.

The structural tradeoff against a private real estate syndication is that the REIT chassis taxes the dividend as ordinary income (with limited exceptions), forces the entity to pay out 90% of taxable income rather than retain it for reinvestment, and prices the underlying portfolio at whatever the public market decides on any given day rather than at the asset's intrinsic value. Those three constraints are what separate REIT investing from the private syndication route, and they explain most of the after-tax return gap between the two.

What Properties do REITs Invest in?

The publicly-traded REIT universe covers most income-producing real estate categories, which is part of the appeal as a diversified entry point into the asset class. NAREIT (the industry trade association) tracks roughly twelve major property-sector groupings across the publicly-listed REIT market, with multifamily, retail, office, industrial, healthcare, data centers, cell towers, and self-storage being the largest by aggregate market capitalization. Each property sector has its own demand drivers, supply dynamics, and cyclical pattern, which means a portfolio built from multiple REITs ends up looking quite different from one built from a single sector.

The four categories that matter most to an accredited investor evaluating REITs as an alternative to private real estate are residential (multifamily), retail (shopping centers and free-standing retail), office, and healthcare. These four together account for a meaningful share of total REIT market cap and represent the cleanest comparison set against the private syndication market, where multifamily is the most common LP-facing product. The structural tradeoffs covered in the rest of this section apply across all four, with sector-specific nuances on top.

Residential Properties

Residential REITs own and operate apartment communities, manufactured housing parks, single-family rental portfolios, and in some cases student housing, and they are the public-market analog to the private multifamily syndication product. The largest publicly-traded multifamily REITs (Equity Residential, AvalonBay, Camden Property Trust, Mid-America Apartment Communities, Essex) collectively own hundreds of thousands of units across major US metros, and their portfolios skew toward Class A urban product in coastal and high-cost markets.

The case for residential REITs over private multifamily syndications usually rests on three points: liquidity at any market open, no accreditation gating, and instant diversification across the REIT's full portfolio rather than a single property or small set of properties. The case against rests on the tax treatment (ordinary-income dividends with no depreciation pass-through to the shareholder), the correlation to the broader equity market (residential REIT share prices have routinely dropped 20 to 30 percent during S&P drawdowns even when the underlying buildings were collecting rent normally), and the structural cap on retained capital that limits the REIT's ability to reinvest meaningfully in value-add improvements without raising new equity or debt.

For an accredited investor who specifically wants apartment exposure, the choice between a residential REIT and a private multifamily syndication is rarely an either-or. Most institutional-style LP allocations end up with both, sized to match the investor's liquidity needs against the appetite for the K-1 depreciation shield and the private-market return premium.

Retail Properties

Retail REITs own shopping centers, malls, free-standing retail, and net-leased retail product, and the sector has been one of the more volatile categories in the public market over the past decade. Regional mall REITs lost meaningful share-price value through the 2018 to 2020 retail apocalypse narrative and again through the COVID closures, while grocery-anchored neighborhood centers and free-standing net-leased retail (think Realty Income's portfolio of single-tenant Walgreens, Dollar General, FedEx properties) held up materially better.

The fundamental risk in any retail REIT is tenant credit. A retail property's rent roll is built on individual store leases, and the underlying tenants compete with e-commerce, with each other, and with shifts in consumer spending patterns that can change faster than the REIT can re-tenant the space. When evaluating a retail REIT, the anchor question is not the headline dividend yield but the credit quality and lease structure of the top tenants in the portfolio. A 5 percent yield from a portfolio leased to investment-grade tenants on long-term triple-net leases is a different security than a 5 percent yield from a portfolio of regional mall space with rolling lease maturities.

Office Properties

Office REITs own commercial office buildings, typically the Class A high-rise product in major metros, and the sector has been the cleanest example of how a structural shift in the underlying asset can flip a long-stable REIT category into a problem. The post-2020 move toward hybrid and remote work has materially reduced office utilization across most major US markets, and the resulting vacancy increases, lease-rollover risk, and capex requirements have pushed office REIT share prices down by half or more from pre-pandemic levels in many cases.

The investor question on office REITs today is not whether the headline cap rate looks attractive (it almost always does, at current depressed prices) but whether the underlying buildings will generate the rent and occupancy implied by the trailing financials over the next five to ten years. Some markets and some specific product types (newer Class A buildings in growing Sun Belt metros, life-sciences office in Boston and the Bay Area) are likely to hold up better than the broader category. Older Class B office in declining markets is structurally challenged in a way that no operator skill can fully offset.

Healthcare

Healthcare REITs own medical office buildings, hospitals, senior housing, skilled nursing facilities, and life-sciences research properties. The sector splits cleanly into two categories with very different risk profiles. Triple-net-leased healthcare property (where the REIT owns the building and a healthcare operator runs the business under a long-term lease) behaves more like a credit instrument tied to the operator's ability to pay rent. Operating-property healthcare (where the REIT actually runs the senior housing or skilled nursing business through a related entity) behaves more like a healthcare operating company with all of the labor cost, regulatory risk, and reimbursement exposure that implies.

For an accredited investor, the healthcare REIT category is the most operationally complex of the major REIT sectors, and the headline yields can mask significant underlying risk in the operating-property segment that does not show up in a casual screening. The triple-net side is closer in risk profile to a high-quality corporate bond than to traditional real estate, while the operating-property side is closer to investing in a healthcare services company than in real estate.

How does a Business Qualify as REIT?

The REIT tax status comes from IRC §856 through §859, and the rules are specific enough that the entity has to be structured deliberately from inception to qualify and to maintain qualification annually. A failure to meet any one of the threshold tests in a given tax year forfeits REIT status and triggers full corporate taxation on the entity, which is the kind of outcome that gets management replaced.

• Asset test: At least 75 percent of the entity's total assets must be invested in real estate, cash, or government securities.
• Income test: At least 75 percent of gross income must come from real estate sources, meaning rents from real property, interest on mortgages secured by real property, or gains from the sale of real estate.
• Corporate taxation: The entity must be organized as and taxable as a corporation, with a board of directors or trustees overseeing management.
• Distribution test: At least 90 percent of the entity's taxable income must be distributed to shareholders as dividends each year, which is the structural rule that drives the high payout ratios across the REIT sector.
• Ownership tests: The REIT must have at least 100 shareholders, and no more than 50 percent of its outstanding shares can be held by five or fewer individuals (the so-called "five or fewer" rule).

The 90 percent distribution requirement is the most structurally important constraint for an investor comparing REITs to private syndications. It forces the REIT to push almost all of its earnings out as dividends rather than retain capital for reinvestment, which in turn means most growth in a REIT's portfolio has to be funded by issuing new equity or new debt rather than from internally-generated cash. Private syndications operate under no such mandate, which is part of why our value-add deals can fund their capex programs from operations and refi proceeds rather than calling additional capital from LPs.

Which Types of REIT Invests Directly in Properties?

REITs split structurally into three categories based on what they actually do with the capital they raise.

Equity REITs own and operate the underlying real estate directly, which is the structure most retail investors picture when they think of a REIT. The income comes from rent collected on the operating property, and the return profile includes both the dividend yield and any appreciation in the underlying real estate over the holding period. The major publicly-traded multifamily, retail, office, healthcare, industrial, and self-storage REITs are all equity REITs. This category accounts for the substantial majority of the REIT market by capitalization and is the most direct public-market analog to private real estate investing.

Mortgage REITs hold portfolios of real estate debt rather than the property itself, earning income from the interest spread between what they pay for borrowed capital and what they earn on the mortgages they own. The model is structurally levered: a mortgage REIT typically funds a long-duration mortgage portfolio with shorter-duration repo borrowing, which means the underlying business is heavily exposed to changes in the slope of the yield curve and to mortgage prepayment behavior. Mortgage REIT yields look high relative to equity REITs (often in the 8 to 12 percent range) for the same reason high-yield bond yields look high relative to investment-grade: the underlying risk is materially higher. We operate strictly on the equity side of multifamily and have not held or sponsored debt-side product as of 2026.

Hybrid REITs combine both approaches in a single entity, holding direct property along with a mortgage or mortgage-backed-securities portfolio. The category is smaller than either equity or mortgage REITs and has fallen out of favor in the public market over the past decade, in part because investors generally prefer pure-play exposure they can size deliberately within an allocation.

REIT Investing & Passive Income

Calling a REIT a passive investment is technically accurate (the shareholder makes no operating decisions) but it understates how active the position actually is from a portfolio-management perspective. REIT share prices move with the broader equity market on most trading days, which means a REIT allocation has to be sized and rebalanced like any other stock position rather than set aside and forgotten. Investors who treat REIT shares as a sleep-at-night income vehicle the way they would a Treasury bond or a CD typically discover during the next equity drawdown that the position behaves nothing like the income vehicles it was supposed to substitute for.

The income stream itself is passive in the IRS sense. The dividends arrive quarterly without any action required from the shareholder, and the entity handles every operational decision from acquisition through disposition. The distinction worth making is between operational passivity (true of both REITs and private syndications) and price stability (true of neither, but REIT prices reset publicly every second while private syndication valuations only reset at major events). For an LP whose objective is durable monthly cash flow that does not vanish during a stock-market correction, the price-stability question is the load-bearing one, and it generally pushes the allocation toward private real estate rather than public REITs at the margin.

How does a REIT Profit?

An equity REIT generates operating profit the same way a private real estate portfolio does: rental income minus operating expenses, debt service, and overhead, with what is left over distributed as the dividend. The headline difference is scale and diversification. A large publicly-traded REIT might own hundreds of properties across dozens of markets, which spreads operating risk across a much wider base than any single private syndication can match. The cost of that diversification is the entity-level overhead (corporate G&A, public-company reporting, executive compensation) that consumes a meaningful share of the operating income before it reaches the shareholder.

The 90 percent distribution mandate caps how much of that operating income the REIT can retain for reinvestment, which is one of the structural reasons REIT growth tends to come from issuing new shares or new debt rather than from compounding internal cash flow. When the REIT acquires a new property, that acquisition is generally funded by tapping the capital markets rather than from retained earnings, and the dilutive effect on existing shareholders is a real factor in the long-run total return.

Private syndications operate under different mechanics. Our own multifamily deals are each a single special-purpose entity holding a single property, with a defined hold period (typically 5 to 7 years), a defined business plan (value-add through unit renovations and operational improvements), and a return structure that pays LPs a cumulative-and-compounding preferred return out of operating cash flow before any GP promote kicks in. Most of the return comes through the back end at refinance and sale rather than through the in-hold distributions, which is a fundamentally different cash-flow shape than a REIT dividend stream and produces a different after-tax outcome for the LP through depreciation pass-through on the K-1.

Frequently Asked Questions About Whats REIT

What's a REIT - Conclusion

A REIT gives a retail investor liquid, diversified exposure to commercial real estate at any account size, and that accessibility is the reason the structure has grown from a 1960 legislative experiment into a multi-trillion-dollar global asset class. For an investor without accreditation, without enough capital to meet syndication minimums, or with a specific need for daily liquidity, the REIT chassis genuinely solves a problem that the private market does not.

For an accredited investor with long-duration capital, though, the harder comparison is against the private real estate syndication market. The REIT structure gives up three things that matter materially over a multi-year hold: the K-1 depreciation pass-through that shelters most of the cash distribution from current tax, the price decorrelation from the broader equity market that makes private real estate a useful diversifier in a stock-market drawdown, and the ability of the deal entity to retain capital for value-add reinvestment rather than push 90 percent of earnings out as taxable dividends. Those three structural advantages of the private route are the reason most institutional allocators put the majority of their real estate exposure in private vehicles rather than in public REITs, even though the public route is simpler to access.

The right answer for any specific investor is rarely either-or. A measured allocation across both public REITs (for liquidity and diversification) and private syndications (for the tax and return profile) usually outperforms either single-route approach over a full cycle. Where the line falls depends on the investor's liquidity needs, accreditation status, and the share of total capital they are willing to deploy into illiquid positions with 5- to 7-year hold periods.
