Real Estate Investment Trust (REIT)

How Does a REIT Work?

REITs can invest in all property types, although most specialize in specific property types. There are around 160 US public REITs with a combined market cap of $1 trillion (Globally, there are 300 REITs with a market cap of $3 trillion).

Most REITs are publicly traded, which enables investors to gain access to a diversified collection of income-producing real estate similar to investing in mutual funds.  Unlike regular companies that can hold on to their profits, REITs must distribute at least 90% of their profits every year back to shareholders in the form of dividends.

As a result of the dividend requirement, the dividend yield on REIT stocks is above 4% – significantly higher than the 1.6% dividend yield for the S&P 500 overall.

In addition to facilitating diversification and high dividend yield, the other major benefit of REITs over other forms of real estate investment is the tax advantages.

Why Invest in REITs?

REITs are a tax-efficient, diversified alternative to direct real estate ownership and investment.

Rather than having to buy and maintain actual physical real estate properties, investors can simply own REIT shares, which are backed by physical assets managed by the REIT.

Feature REITs Real Estate
Liquidity (Easy to buy and sell) Advantage
Low capital intensity (Doesn’t require a lot of capital to invest upfront) Advantage
Diversification (Easy to invest in multiple property types across geographies) Advantage
Control (Influence on management and strategy) Advantage

What are the Historical Returns on REITs?

Contrasting REIT vs Real Estate returns is a little more complicated.

REITs have generated 10% in annualized returns over the long run (including the last 10 years).

Meanwhile, real estate assets have grown at 2-3% annually, seemingly giving an advantage to REITs.  However, this is not an apples-to-apples comparison.

A huge accelerator of returns is leverage: The average debt / total value for Equity REITs is 37.0% as of 2020 (Source: NAREIT).

Meanwhile, direct real estate investment can range widely, but at the high end, investors can secure debt upwards of 80% of the total property value, which all else equal amplifies returns (and risk) significantly.

What are the Tax Advantages of REITs?

Entities qualifying for REIT status under the tax code receive preferential tax treatment: The income generated by REITs is not taxed on the corporate level and is instead taxed only on the individual shareholder level.

Specifically, REIT profits pass through – untaxed –to shareholders via dividends.

This is a tax advantage over C-corporations, which are taxed twice – first, on the corporate level, and then a second time on the individual level via a tax on dividends.

In order to qualify for this tax status, REITs must comply with certain requirements, the biggest one being that REITs are required to distribute nearly all profits (at least 90%) as dividends 

What are REIT Dividends?

REIT dividends are cash distributions to REIT shareholders. REITs distribute almost all of their profits as dividends.

REIT dividends are typically “non-qualified” dividends, meaning they are taxed at ordinary income tax rates (up to 29.6%1), as opposed to the lower capital gains (up to 20%) on the shareholder level.

That doesn’t sound so great but remember that this is the only tax the investor pays because REITs entirely avoid a corporate-level tax.

In contrast, in a C-corp, there is a corporate-level tax (up to 21%), followed by a second tax on any dividends distributed to shareholders (albeit at the lower capital gains rate of 20% because C-corp dividends are typically “qualified dividends”).

REIT vs. C-Corp: What is the Difference?

This simple illustration shows the basic difference between the single pass-through taxation of a REIT and the double taxation of a C-corp.

Note, however, the following model is a simplification of a rather complex topic.

REIT tax rules can get quite complicated, especially if tax breaks for depreciation are brought into the picture, which can further increase the tax advantages of REITs.

How Does a Company Qualify as a REIT?

In order to qualify and be formally recognized as a REIT, the following requirements must be met (and abided by):

Requirement Description
Dividends At least 90% of taxable income must be distributed as a dividend

  • Income not distributed is taxed at the corporate level
Gross income

(annual test)

At least 75%of gross income must come from

  • Rents from real property
  • Interest income from mortgages held
  • Gain from the sale of real property/shares of other REITs
  • Certain qualified investment income

At least 95% of gross income must come from

  • All of the above, plus:
  • Dividends, interest, and gain on sale from non-real estate investments
Assets At least 75% of assets must be
Real estate, mortgages, equity in other REITs, cash, and government securities
  • A REIT’s taxable subsidiaries (companies providing services to tenants in REIT buildings) must be < 25% of the REIT’s assets
  • Their income does not count toward the 75% income test
  • Shares must be owned by at least 100 shareholders
  • Must have transferrable shares
  • No more than 50% of shares outstanding can be owned by 5 or fewer people (“5/50 test”)
  • Although not a legal requirement, virtually all REITs limit individual ownership to 9.9%
  • Must be a domestic corporation for federal tax purposes
  • Cannot be a financial institution or insurance company
  • Must have a calendar year tax year

What are the Different Types of REITs?

Equity vs. Mortgage REITs

Most REITs directly own the real estate and are called equity REITs. However, a few REITs simply own mortgages (Mortgage REITs) and collect income (interest income) from the mortgages.

REIT Type Description

90% of total

Equity REITs acquire, develop, and then operate its own properties, unlike other real estate companies which tend to resell once developed

10% of total

Purchase debt (real estate loans and mortgage-backed securities)

Internal vs. External Management

REITs can be internally or externally managed

REIT Type Description
Internal management
  • Management are employees of the REIT
  • Majority of public REITs are internally managed
External management
  • Similar to private equity, external management receives flat and incentive fees for managing the real estate portfolio
  • Flat fee based on assets under management
  • Incentive fee based on returns from the sale of assets
  • Typically incentive fee carries a high water mark (i.e. only kicks in if NAV exceeds the highest historical NAV)
  • Private and mortgage REITs tend to be externally managed

How to Analyze REITs?

When valuing REITs, investors look at both traditional profit metrics such as EBITDA, as well as real estate and REIT-specific metrics, including:

  1. Net Operating Income (“NOI”)
  2. Funds from Operations (“FFO”)
  3. Adjusted Funds from Operations (“AFFO”)
  4. Capitalization Rate (“Cap Rate”)

What are the Key REIT Metrics? 

Net Operating Income (NOI)

Net operating income, or “NOI”, is the most important profit measure in real estate.

NOI strives to isolate to core operating profits of real estate assets, so as to avoid muddying the waters with non-operating items such as corporate overhead and major non-cash items like depreciation.

In a sense, NOI is similar to EBITDA, but with even more add-backs to really focus on pure operating income generated by the properties.

Net Operating Income (NOI) = Rental and Ancillary Income Direct Real Estate Expenses

Thus, NOI captures profitability before any depreciation, interest, taxes, corporate-level SG&A expenses, capital expenditures, or financing payments

Funds from Operations (FFO)

While NOI is a useful profit measure for analyzing real estate down to the property level, FFO is a real estate-specific metric for cash generated from operations.

FFO is an attempt to reconcile accounting (GAAP) net income to a consistent measure of profit specifically tailored for analysis of REITs. In fact, most REITs provide FFO reconciliations in their filings.

Funds From Operations = Net Income to Common + Depreciation Gains on Sale + Non-Controlling (NCI) Interest Expense, net of NCI Cash Dividends

While often misunderstood, FFO is NOT actually designed to be a measure of cash flow because the formula excludes working capital, capital expenditures (Capex), and other cash flow adjustments

Learn More → Funds from Operations (FFO)

Adjusted FFO (or Cash Available for Distribution)

Over time, analysts and REITs themselves have begun using slightly altered versions of FFO, generally called “adjusted FFO” or AFFO.

The reason for this is that FFO included things like nonrecurring items and notably omitted key outflows like capital expenditures.

While there remains some inconsistency across how these are calculated, the most common calculation is:

Adjusted Funds from Operations (AFFO) = FFO + Nonrecurring Expenses – Capital Expenditures

Note: The adjusted funds from operations (AFFO) is also known as cash available for distribution or “CAD”.

Learn More → Adjusted FFO

Cap Rate (Capitalization Rate)

The cap rate, along with NOI are arguably the most important metrics in real estate. Unlike NOI or FFO, however so far, the cap rate is not actually a measure of profit, but rather a yield measure.

It measures the real estate property’s operating profit as a % of the property’s value. If you’re familiar with EV/ EBITDA multiples, the closest thing to a cap rate is an inverse EBITDA multiple.

Cap rates are the primary shorthand by which different real estate properties are compared by investors.  For example a property with a 10% cap rate provides a better yield than a comparable property with a 7% cap rate.

Cap Rate = Net Operating Income (NOI) ÷ Market Value of Property

Capitalization Rate Calculation Example

A property with an asking price of $1m and NOI of $125k will have a $125k / $1 m = 12.5% cap rate

As we’ve noted, cap rates are simply the inverse of a traditional valuation multiples like EV/EBITDA.

What Factors Influence the Cap Rate?

Just as with traditional multiples, there are many variables that can distort the comparison of properties using this metric, including:

  1. Timing of NOI (LTM or forward)
  2. Growth rates
  3. Returns on capital
  4. Cost of capital of properties (or REITs) being compared

However, in real estate, it is much easier to find comparable properties (with therefore similar growth, returns, and cost of capital profiles), which mutes the problems described above.

How to Build a REIT Model in Excel

A REIT model will first forecast the financial statements and then apply the valuation methodologies discussed above to arrive at an investment thesis.

The key challenges in modeling REITs include modeling individual (same-store properties, acquisitions, developments, and dispositions) using the appropriate drivers and occupancy rate assumptions: Obviously mature properties with stable occupancy rates will have a different forecast profile than properties under development.

A second challenge is working with a real company’s financial statements. This requires digging into a REIT’s financial statements and ensuring consistent and logical modeling of REIT-specific metrics and ratios like funds from operations (FFO) and adjusted funds from operations (AFFO / CAD).

What are the REIT Valuation Methods?

So, how can the value of a REIT be determined?

In practice, analysts primarily value REITs using the following four approaches:

  1. Net Asset Value (“NAV”)
  2. Discounted Cash Flow (“DCF”)
  3. Dividend Discount Model (“DDM”)
  4. Multiples and Cap Rates

The most common of these approaches is the NAV and DDM due to the unique features of REITs.

What are the Other Types of Real Estate Companies?

There are other types of companies in real estate, most notably real estate private equity firms, as well as Real Estate Investment Management firms and REOCs, all with different characteristics and considerations.

The biggest difference between REITs and these other real estate companies is that REITs are publicly traded and report earnings quarterly.

From a strategy perspective, REITs tend to have a much lower risk tolerance than private real estate investment firms, which results in REITs’ portfolios consisting of primarily core assets (meaning more stable, lower cap rates), an aversion to redevelopment and development, and much less acquisition and disposition activity. Asset management roles are featured prevalently at most REITs.
