Equity REITs vs. Mortgage REITs: What's the Difference?

Equity REITs vs. Mortgage REITs: Understanding the Two Main Types of REITs

When most people hear the word "REIT," they picture a company that owns buildings — apartment complexes, shopping centers, or office towers. And while that description fits many REITs, it does not capture the full picture. The two primary categories of real estate investment trusts — equity REITs and mortgage REITs — operate in fundamentally different ways, carry different risk profiles, and generate income through entirely different mechanisms.

Understanding the difference between equity REITs and mortgage REITs is essential for any investor exploring the REIT space. One type owns physical real estate and collects rent. The other finances real estate and earns interest income. Both are structured as REITs under U.S. law, but they behave very differently as investments.

By the end of this article, you will understand how each type works, how they generate income, the risks associated with each, and what investors typically look for when comparing them.

What Are Equity REITs?

Equity REITs are the most common type of REIT. According to Nareit, the industry's leading trade association, equity REITs make up the majority of the U.S. REIT market. These companies directly own and typically manage income-producing properties. Their primary business is to acquire, operate, and maintain real estate assets and collect rental income from tenants.

Equity REITs invest across a wide variety of property sectors, including:

• Residential apartments and multifamily housing
• Office buildings
• Retail shopping centers and malls
• Industrial warehouses and logistics centers
• Healthcare facilities and medical office buildings
• Data centers and cell towers
• Self-storage facilities
• Hotels and hospitality properties

According to Nareit, REITs of all types collectively own more than $4.5 trillion in gross assets across the United States, and U.S. public REITs own an estimated 570,000 properties across all 50 states. The vast majority of that ownership is concentrated in equity REITs.

How Equity REITs Generate Income

Equity REITs earn money primarily through two channels:

1. Rental income: Tenants pay rent for the use of the REIT's properties. The REIT collects this rent, covers operating expenses (such as property taxes, maintenance, and management costs), and distributes the remaining income to shareholders as dividends.
2. Property appreciation: When a REIT sells a property for more than it paid, it generates a capital gain. This gain may be distributed to shareholders or reinvested in new properties.

Like all REITs, equity REITs must distribute at least 90% of their taxable income to shareholders each year. Most distribute close to 100% to avoid paying corporate income tax at the entity level.

What Are Mortgage REITs (mREITs)?

Mortgage REITs — commonly abbreviated as mREITs — operate very differently from equity REITs. Rather than owning physical properties, mortgage REITs provide financing for real estate by purchasing or originating mortgages and mortgage-backed securities (MBS). In essence, mREITs function more like financial companies than property companies: they are lenders and investors in real estate debt, not owners of real estate.

According to Nareit, mREITs invest in both residential and commercial mortgages, as well as residential mortgage-backed securities (RMBS) and commercial mortgage-backed securities (CMBS). Their fundamental business is to earn a profit from the net interest margin — the spread between the interest they earn on mortgage assets and the cost of the short-term debt they use to finance those investments.

How Mortgage REITs Generate Income

mREITs earn income primarily from interest payments on the mortgages and mortgage-backed securities they hold. Their income model has two key elements:

• Interest income: Borrowers or the agencies that guarantee mortgage-backed securities make regular interest payments to the mREIT.
• Leverage and spread: Many mREITs borrow money at short-term interest rates and invest the proceeds in longer-term mortgage assets that yield higher interest rates. The difference between what they earn and what they pay to borrow is the net interest margin — the source of their profit.

This leverage-driven model is one reason mREITs can offer higher dividend yields than equity REITs. It is also one reason they carry greater risk.

Agency vs. Non-Agency Mortgage REITs

Within the mortgage REIT category, investors often distinguish between:

• Agency mREITs: These invest primarily in mortgage-backed securities guaranteed by U.S. government-sponsored enterprises such as Fannie Mae, Freddie Mac, or Ginnie Mae. Because these securities carry a government guarantee, they carry minimal credit risk (the risk of borrower default). However, they are still highly sensitive to interest rate changes.
• Non-agency mREITs: These invest in mortgages and mortgage-backed securities without government guarantees. They carry higher credit risk but may offer higher potential returns.

What Are Hybrid REITs?

A third, less common category — hybrid REITs — combines elements of both equity and mortgage REITs. Hybrid REITs own physical real estate properties and also invest in mortgages and mortgage-backed securities. This structure allows them to earn both rental income and interest income. Hybrid REITs are far less common than pure equity or mortgage REITs.

Key Differences Between Equity REITs and Mortgage REITs

The following summary highlights the most important differences between equity REITs and mortgage REITs:

• What they own — Equity REITs: Physical properties (buildings, land). Mortgage REITs: Mortgages and mortgage-backed securities.
• How they earn income — Equity REITs: Rental income and property sales. Mortgage REITs: Interest on loans and MBS.
• Primary risk — Equity REITs: Property value, occupancy, and real estate market cycles. Mortgage REITs: Interest rate changes, prepayment, and credit risk.
• Dividend yield profile — Equity REITs: Generally moderate and stable. Mortgage REITs: Often higher but more volatile.
• Use of leverage — Equity REITs: Less reliant on short-term borrowing. Mortgage REITs: Often rely heavily on leveraged short-term borrowing.
• Sensitivity to interest rates — Equity REITs: Less directly sensitive. Mortgage REITs: Highly sensitive to interest rate movements.

How It Works in Practice: Hypothetical Examples

The following examples use hypothetical, made-up numbers to illustrate how each type of REIT works. These are not real REITs or actual financial data.

Hypothetical Equity REIT Example

Imagine a hypothetical equity REIT called Westview Properties Trust. Westview owns a portfolio of 50 apartment buildings across several states. It collects a total of $20 million in annual rent from tenants. After paying $8 million in operating expenses (maintenance, insurance, property taxes, management fees), Westview has $12 million in net operating income. After paying interest on its debt and other costs, it has $9 million in taxable income. To maintain its REIT status, it distributes at least 90% of that — approximately $8.1 million — to shareholders as dividends.

If property values increase over time, Westview may also sell properties at a gain and reinvest proceeds into new acquisitions, growing its portfolio and potential income over time.

Hypothetical Mortgage REIT Example

Now imagine a hypothetical mortgage REIT called NorthStar Mortgage Trust. NorthStar does not own any buildings. Instead, it holds a portfolio of agency mortgage-backed securities — bonds backed by pools of residential mortgages guaranteed by government-sponsored enterprises. These MBS pay NorthStar an average interest rate of 5% per year.

To increase its returns, NorthStar borrows money through short-term repurchase agreements (repos) at an interest rate of 3%, then uses those borrowed funds to purchase additional MBS yielding 5%. The 2% spread on the leveraged portion is its net interest margin. As long as short-term rates remain below the yield on its MBS portfolio, the strategy is profitable. However, if short-term interest rates rise sharply, the cost of borrowing could approach or exceed what NorthStar earns on its portfolio, compressing or eliminating its profit margin.

Why the Difference Matters to REIT Investors

Income Stability

Equity REITs tend to generate relatively stable rental income backed by long-term lease agreements. This makes their dividend income more predictable over time, though it is still affected by economic cycles, vacancy rates, and property market conditions.

Mortgage REIT income depends heavily on the interest rate environment. When interest rates change rapidly — especially when short-term rates rise faster than long-term rates — a mortgage REIT's net interest margin can shrink significantly, leading to dividend cuts.

Dividend Yield

Mortgage REITs often offer higher current dividend yields than equity REITs. This is largely because mREITs use leverage to amplify returns, and because they pass through substantial interest income to shareholders. However, higher yields come with higher risk. An mREIT that cuts its dividend due to interest rate pressure can see its share price drop sharply.

Interest Rate Sensitivity

This is one of the most important distinctions between the two types. Mortgage REITs are significantly more sensitive to interest rate movements than equity REITs. When interest rates rise, several things happen to mREITs simultaneously: the value of existing MBS tends to fall, borrowing costs rise, and prepayment patterns shift. Equity REITs are affected by interest rates too — primarily because rising rates increase borrowing costs and can make REIT dividend yields look less attractive compared to bonds — but the relationship is less direct than it is for mREITs.

Portfolio Role

Equity REITs provide exposure to real estate as a hard asset class with potential inflation protection, since landlords can increase rents over time. Mortgage REITs behave more like fixed-income or credit investments, since their returns are driven by interest rates and credit spreads rather than property values. Some investors use both types for different purposes in their portfolios.

Risks and Considerations

Equity REIT Risks

• Real estate market risk: Property values can decline due to economic downturns, oversupply, or local market conditions.
• Tenant and occupancy risk: If tenants vacate or fail to pay rent, income declines. Vacancy rates directly affect revenue.
• Property-sector risk: REITs focused on a single sector (such as retail malls or office buildings) can suffer when that sector faces challenges.
• Interest rate risk: Rising rates increase borrowing costs and can reduce property valuations.
• Management risk: Poor property acquisition decisions or capital allocation can reduce returns.

Mortgage REIT Risks

• Interest rate risk: This is the dominant risk for mREITs. Rapid changes in interest rates — particularly when short-term rates rise faster than long-term rates — can compress net interest margins and reduce earnings significantly.
• Prepayment risk: When interest rates fall, homeowners refinance their mortgages and repay their loans early. The mREIT must reinvest that returned principal at lower rates, potentially reducing income.
• Credit risk: For non-agency mREITs, if borrowers default on their mortgages, the mREIT suffers losses. Agency mREIT securities carry government guarantees, which largely eliminate default risk, but non-agency portfolios do not.
• Leverage and liquidity risk: Many mREITs use short-term borrowing to fund long-term assets. If short-term credit markets become stressed, the mREIT can face a funding crisis.
• Dividend volatility: Because mREIT income depends on the interest rate spread, dividends can be cut quickly when rate conditions change unfavorably.

Important Metrics for Each REIT Type

For Equity REITs

• Funds From Operations (FFO): The standard REIT earnings metric defined by Nareit. FFO equals net income plus real estate depreciation and amortization, minus gains from property sales. Because depreciation reduces GAAP net income even as properties may hold or increase their value, FFO provides a clearer picture of recurring operating performance.
• Net Operating Income (NOI): Total property revenues minus direct operating expenses (before interest, taxes, and depreciation). NOI measures the income generated by properties before financing and overhead costs.
• Occupancy rate: The percentage of rentable space that is currently occupied and generating revenue.
• Dividend yield: Annual dividends per share divided by the current share price.

For Mortgage REITs

• Net interest margin (NIM): The spread between interest earned on mortgage assets and interest paid on borrowed funds. This is the fundamental driver of mREIT profitability.
• Book value per share: The net asset value of the mREIT's portfolio divided by shares outstanding. mREIT share prices often trade at a discount or premium to book value.
• Leverage ratio: How much debt the mREIT uses relative to its equity. Higher leverage amplifies both gains and losses.
• Dividend yield: mREITs often have higher yields than equity REITs, reflecting their leveraged income model and higher risk.

Note: FFO is a metric designed for equity REITs that own depreciating real estate assets. It does not apply to mortgage REITs, whose assets are financial instruments. For mREITs, investors typically focus on earnings available for distribution (EAD), book value, and net interest margin.

Common Mistakes to Avoid

• Assuming all REITs are the same: Equity REITs and mortgage REITs have fundamentally different business models, risk profiles, and income sources. Treating them interchangeably can lead to unexpected outcomes.
• Chasing high mREIT yields without understanding the risks: A high dividend yield on an mREIT reflects higher risk, not guaranteed income. Mortgage REIT dividends have been cut during periods of interest rate volatility.
• Ignoring interest rate risk for mREITs: Even relatively small shifts in the yield curve can have large effects on mREIT earnings and dividends.
• Applying FFO analysis to mortgage REITs: FFO is designed for equity REITs. Using the wrong valuation metric for an mREIT produces misleading conclusions.
• Overlooking leverage: Mortgage REITs often use significant leverage. High leverage amplifies losses, not just gains.
• Ignoring sector differences within equity REITs: A retail-focused equity REIT carries different risks than a data center REIT or a healthcare REIT. Understanding the underlying property sector matters.

Frequently Asked Questions

Are equity REITs safer than mortgage REITs?

Generally speaking, equity REITs are considered less volatile than mortgage REITs because their income comes from rents backed by real property rather than leveraged interest rate spreads. However, equity REITs still carry real estate market risk, tenant risk, and sector-specific risks. No REIT is risk-free.

Why do mortgage REITs pay higher dividends?

Mortgage REITs typically pay higher dividends than equity REITs because they use leverage to amplify interest income — borrowing at short-term rates and investing in higher-yielding mortgage assets. The higher yield reflects the higher risk associated with this model, particularly its sensitivity to interest rate changes and leverage.

Can I invest in both equity REITs and mortgage REITs?

Yes. Many investors hold both types, though with different allocations based on their income goals and risk tolerance. Some diversified REIT ETFs include both equity and mortgage REITs. Others focus exclusively on one type or the other.

Does FFO apply to mortgage REITs?

FFO (Funds From Operations) is a metric designed specifically for equity REITs that own depreciating real estate assets. It does not apply to mortgage REITs, whose assets are financial instruments. For mREITs, investors focus on net interest income, earnings available for distribution (EAD), and book value metrics.

How do interest rate changes affect equity REITs vs. mortgage REITs?

Rising interest rates affect both types differently. For equity REITs, higher rates increase borrowing costs and can make dividend yields look less attractive relative to bonds. The effect on income is less direct because rents are contractual. For mortgage REITs, rising rates are more immediately threatening: they increase borrowing costs, compress net interest margins, and reduce the market value of existing MBS. Mortgage REITs are generally considered more sensitive to interest rate changes than equity REITs.

What is a hybrid REIT?

A hybrid REIT combines characteristics of both equity and mortgage REITs. It directly owns real estate properties and also holds mortgages or mortgage-backed securities. Hybrid REITs earn both rental income and interest income, but they are less common than pure equity or mortgage REITs.

Conclusion

The distinction between equity REITs and mortgage REITs is one of the most fundamental concepts in REIT investing. Equity REITs own physical real estate and earn income from rents and property appreciation. Mortgage REITs own mortgages and mortgage-backed securities and earn income from interest. These two types carry different risk profiles, respond differently to interest rate environments, and serve different roles in an investor's portfolio.

Equity REITs are generally considered more stable, with income backed by leased properties and long-term real estate fundamentals. Mortgage REITs typically offer higher dividend yields, but that yield comes with greater sensitivity to interest rates, leverage, and credit market conditions.

Neither type is inherently better than the other — the right choice depends on your investment goals, risk tolerance, and how REITs fit within your broader portfolio. The key is to understand what you own before you invest.
