Equity REITs vs Mortgage REITs
Equity REITs vs Mortgage REITs
There are two fundamentally different types of REITs. Equity REITs own and operate real estate properties. Mortgage REITs, also called mREITs, finance property acquisitions by holding mortgages and mortgage-backed securities. The distinction is simple: equity REITs own the building; mortgage REITs own the mortgage on the building. This difference creates vastly different risk profiles, return drivers, and interest-rate sensitivities.
Key takeaways
- Equity REITs own income-producing properties and are sensitive to real estate market fundamentals—rent growth, vacancy, property values.
- Mortgage REITs hold mortgages and mortgage-backed securities, earning interest income, and are highly sensitive to changes in interest rates.
- Equity REITs typically yield 2% to 4%; mortgage REITs often yield 6% to 9% or higher, but with much greater volatility.
- When interest rates rise, equity REITs often fall due to discount rate effects, but mortgage REITs can suffer additional losses if refinancing demand collapses.
- Mortgage REITs are leveraged bets on real estate financing; they are more suitable for income-focused investors with high risk tolerance.
Equity REITs: The property owners
An equity REIT owns and operates real estate properties. Apartment complexes, office buildings, industrial warehouses, shopping centers, healthcare facilities, data centers, and other income-producing assets. The equity REIT collects rents from tenants, pays operating expenses (property taxes, insurance, utilities, maintenance), and distributes the net operating income (after debt service) to shareholders as dividends. The equity REIT's value is driven by the underlying real estate—how much rent it can collect, how efficiently it can operate the properties, and what the properties are worth.
An equity REIT like Realty Income (O), which owns 15,000+ retail properties, operates as a large real estate company. It acquires properties, negotiates leases, maintains buildings, handles tenant relations, and decides when to sell. Its success depends on real estate fundamentals: whether rents are growing, whether vacancies are rising or falling, whether maintenance costs are controllable, and whether it can renew or escalate leases as they expire. Over a 10- or 20-year period, an equity REIT's returns closely mirror the underlying property market. If the U.S. apartment market appreciates 3% per year on average and rents grow 2% per year, an apartment REIT should deliver similar long-term returns (plus the distribution yield).
Mortgage REITs: The real estate lenders
A mortgage REIT does not own property. Instead, it buys mortgages, mortgage-backed securities (MBS), and other real estate debt instruments. When a homebuilder or developer wants to finance a $50 million office tower, the mortgage REIT might originate or buy that $40 million mortgage. The mortgage REIT earns the interest on that debt—if the mortgage carries a 5% interest rate, the REIT collects 5% of the outstanding balance each year. It distributes most of that interest income to shareholders.
Mortgage REITs are therefore lenders, not owners. They do not care about the rental market, occupancy rates, or property management. They care about whether borrowers pay their mortgages on time. A mortgage REIT profits when interest rates are high (it earns more interest income), when credit spreads are wide (borrowers pay more for risky loans), and when the real estate market is strong (defaults are rare). It loses when interest rates fall (it earns less interest on new investments and must mark down the value of existing mortgages), when credit spreads compress (borrowers demand lower rates), and when the real estate market weakens (defaults rise).
Interest rate sensitivity: The critical difference
The most important difference between equity and mortgage REITs is how they respond to interest rate changes. When the Federal Reserve raises interest rates, equity REITs typically fall because the discount rate applied to their future cash flows increases. The same rent-generating property is worth less at a 6% discount rate than at a 4% discount rate. This is the same reason long-duration bonds fall when rates rise. Equity REIT returns correlate modestly with bond returns—both fall when rates rise, though equity REITs are more stable because rents can grow over time.
Mortgage REITs face a double whammy. First, the same discount rate effect: the value of their existing mortgage portfolio falls when rates rise. A $1 million 4% mortgage is worth less when the market rate is 6%. Second, and more severe, when rates rise, new mortgage originations carry higher rates. A mortgage REIT that was buying 4% mortgages can now buy 6% mortgages. But if it is fully deployed (all capital already lent out), it cannot quickly shift its portfolio. It sits with a $1 billion portfolio earning 4% while new loans would earn 6%. Its earnings per share fall until mortgages mature and are replaced at higher rates. Additionally, if rates rise sharply, refinancing demand collapses. Borrowers who could have refinanced their 3% mortgages into 4% mortgages are locked in at 3%. The mortgage REIT's portfolio stagnates and the REIT has trouble deploying capital.
Conversely, when interest rates fall, equity REITs often rise (discount rates fall) and mortgage REITs often fall (because reinvestment rates fall). A mortgage REIT yielding 8% looks attractive in a low-rate environment, but as rates stay low, the REIT must roll off maturing mortgages into new 3% or 4% mortgages. Earnings per share decline and the high yield compresses. This happened to mortgage REITs in 2020 and 2021 when the Fed cut rates to near zero.
Leverage and volatility
Both equity and mortgage REITs use leverage, but mortgage REITs typically use much more. An equity REIT might be 40% debt and 60% equity. A mortgage REIT might be 85% debt and 15% equity. This extreme leverage amplifies returns in good times and losses in bad times. When interest rates are stable and the mortgage REIT earns 8% on its mortgages while paying 3% on its debt, the equity earns 16% (8% times 5.67, which is the leverage multiple). But if rates spike and mortgage values fall 10%, the equity falls 50% or more. Mortgage REITs are inherently more volatile.
Equity REIT leverage is more sustainable because rents typically grow over time, providing a buffer against interest rate volatility. A property that rents for $100 per square foot in 2020 might rent for $110 in 2025, offsetting any increase in debt costs. Mortgage REIT leverage is dangerous during rate spikes because the mortgages do not reprice—the 4% mortgage stays at 4% even if new mortgages carry 6%. The REIT is trapped earning 4% on a declining asset base.
Dividend yields and distributions
Equity REITs typically yield 2% to 4% in normal markets. This yield reflects the rental income and property appreciation potential. Mortgage REITs often yield 6% to 10% or even higher. This high yield attracts income-seeking investors. But the high yield is not "free lunch." It reflects both the interest income the REIT collects and the risk that the yield will compress when interest rates change. A mortgage REIT yielding 9% in a 2% rate environment might yield 5% in a 5% rate environment as the REIT rolls mortgages into lower-yielding investments and interest spreads compress.
Which is right for you?
Equity REITs are suitable for most investors. They offer real estate exposure, reasonable yields, and long-term stability. The returns are tied to real estate fundamentals, not interest rate mechanics. Holding equity REITs in a diversified portfolio makes sense for nearly all investors. Mortgage REITs are more specialized. They are appropriate for investors with high income needs, high risk tolerance, and the expertise to monitor interest rate risk and market conditions. In taxable accounts, neither is ideal because of the high distribution yields. In tax-deferred accounts, equity REITs are the default choice for most people.

Understanding the difference between equity and mortgage REITs is foundational. But within equity REITs, there are further distinctions based on property type. A residential apartment REIT, an industrial warehouse REIT, and a data center REIT each have different growth drivers, cyclicality, and risks.
