Mortgage REITs (mREITs) earn interest on mortgages, real estate loans and mortgage-backed securities, then subtract borrowing and hedging costs. Their dividends depend on taxable income, earnings and financial condition, but the board sets the actual payout. The REIT distribution rule does not promise a particular dividend, yield or payment schedule.
How mortgage REITs make money
Mortgage REITs finance real estate owners and operators directly with mortgages or other real estate loans, or indirectly by acquiring mortgage-backed securities (MBS), as the SEC explains in its investor bulletin. Unlike property-focused REITs, which generally own real estate, mREITs primarily hold or originate debt tied to real estate. Their basic revenue source is interest from those assets.
A useful shorthand is:
Net interest income ≈ interest earned on mortgage assets − borrowing costs − hedge expense (or + hedge income).
This is an explanatory framework, not a universal accounting line item. Portfolio gains and losses, financing structure, securitization, servicing, credit performance and changes in the reported value of investments can also affect results. For example, AGNC Investment Corp. says it earns interest net of associated borrowing and hedging costs, and also has realized gains and losses from investment and hedging activity in its Form 10-Q for the quarter ended June 30, 2026.

#1 Best Overall
Many mREITs use leverage, borrowing to hold a larger portfolio than their equity alone would support. Leverage can amplify returns when assets perform well, but it also magnifies losses and can increase pressure on liquidity when asset values or financing conditions change. The SEC notes that mortgage REITs tend to use more leverage than property-focused REITs and may use derivatives and other hedges to manage interest-rate and credit exposures.
What drives mREIT earnings and dividend capacity
Interest received is only one part of the picture. The outcome depends on asset returns, funding, hedging and portfolio risks working together.
Asset yields and mortgage spreads
Coupon income and the price paid for mortgage assets shape returns. Mortgage spreads—the extra yield on mortgage assets relative to benchmarks such as Treasuries or swaps—can widen or tighten. That can change the market value of existing holdings and the economics of buying new assets.
Rank #2
Borrowing costs and access to financing
Funding expense reduces the interest left over from the portfolio. The availability and terms of secured or short-term borrowing also matter: tighter liquidity or more expensive financing can squeeze the spread or force portfolio changes.
Interest rates, yield curves and hedges
Rate changes can reprice assets and liabilities by different amounts and at different speeds. The effect depends on portfolio duration, how quickly holdings and funding reprice, the shape of the yield curve, and whether hedges behave as intended. Swaps and other derivatives can offset some rate exposure, but they cost money and may not move in line with the assets they are intended to hedge. The SEC cautions that REITs can respond differently to changing rates and that hedging strategies carry risks.
That is why “rates up” does not automatically mean an mREIT will earn more or less. The result depends on the issuer’s particular assets, liabilities, spreads, hedge positions and borrower behavior.
Prepayments and refinancing
When borrowers repay or refinance mortgages sooner than expected, the mREIT receives principal earlier and may have to reinvest it at less favorable yields. Prepayment expectations are one of the market factors AGNC identifies in its June 30, 2026 Form 10-Q, alongside interest rates, liquidity, housing prices and general economic conditions.
Credit exposure and collateral performance
Agency MBS are guaranteed by a government agency or government-sponsored entity, according to AGNC’s Form 10-Q for the quarter ended June 30, 2026. That guarantee changes the credit-risk profile, but does not remove interest-rate, market or liquidity risk. AGNC says repayment on its credit-risk-transfer and non-agency securities is not guaranteed by a government-sponsored entity or the U.S. government; those investments therefore expose holders to borrower defaults, loss severity and collateral values.
Leverage, liquidity and book value
Leverage amplifies movements in asset prices and mortgage spreads relative to the mREIT’s equity. Liquidity conditions can affect whether the company can maintain or replace financing, and may prompt it to sell or adjust holdings. These factors can affect both earnings and book value, the net value of assets after liabilities.
How the REIT distribution rule relates to dividends
The SEC’s 2016 investor bulletin says REITs must distribute at least 90% of their taxable income annually to shareholders. That tax rule is not a guarantee of a specific dividend per share, yield or monthly or quarterly schedule. Taxable income is not the same measure as operating earnings, and neither figure by itself dictates the amount an investor will receive.
The actual distribution is set by the company’s board. In its Form 10-K for the year ended December 31, 2025, AGNC says distributions are at the board’s discretion and depend on earnings, financial condition, REIT qualification requirements and other factors the board considers relevant. A declared dividend, rather than the tax rule alone, establishes the issuer’s announced payout for the specified period.
A quoted dividend yield is the dividend amount divided by the share price; it can change when either changes. A high yield is therefore an observed ratio, not evidence that the dividend is safe or sustainable. Dividend sustainability depends on the issuer’s earnings, financial condition, portfolio risks and board decisions.

For an issuer-specific view, compare recent disclosures from the same reporting periods and use consistent definitions. The SEC recommends reviewing the latest 10-K risk factors; its REIT overview also describes REIT risks, distributions, taxes and investor access routes.
- Latest 10-K and 10-Q: Review the company’s risk factors, reported earnings and explanations of portfolio performance.
- Dividend declaration and policy: Check the latest announced amount and payment period, as well as what management says about distribution decisions.
- Portfolio mix: Identify agency, non-agency and credit-risk-transfer exposure, plus the types of loans, securities, borrowers and collateral held.
- Funding and leverage: Examine financing sources and costs, leverage, and liquidity information.
- Hedges and sensitivities: Review hedge positions, duration mismatches, and disclosed sensitivity to rates, mortgage spreads and prepayments.
- Book value and earnings: Track changes in book value and earnings available for distribution alongside the declared payout; do not treat any single measure as a guarantee.
When comparing two issuers, align the reporting periods and definitions. Differences in portfolio mix, guarantees, leverage, financing, hedges and prepayment sensitivity can make headline yields poor substitutes for understanding risk.
Tax treatment for investors
REIT dividends are generally treated as ordinary income, according to Investor.gov, although an investor’s circumstances can affect the tax treatment. Check current rules with a qualified tax professional rather than assuming every distribution receives the same treatment.
