Before buying a mortgage-related stock, identify what the company owns and how it funds those assets. A bank with mortgage exposure and a mortgage REIT can both be affected by housing and interest rates, but their credit risks, funding mechanics, leverage and valuation measures differ. Examine the company’s filings first; sector statistics and a low price-to-book ratio are context, not a verdict on an individual stock.
First, identify what kind of mortgage company it is
“Mortgage stock” is not one business model. A bank may make or hold mortgage loans and mortgage-backed securities while funding much of its balance sheet with deposits. A mortgage REIT may own mortgage-backed securities, originate or acquire mortgage loans, and use repurchase agreements (repo), securitizations or other secured borrowing. Some businesses combine activities, so classify the issuer by its actual assets, funding and earnings sources rather than its name.

This distinction matters because the same market event can reach each balance sheet differently. Higher funding costs may squeeze a bank’s net interest margin or a REIT’s spread between asset yields and borrowing costs. Falling asset values can affect equity and, for a repo-funded REIT, may also prompt a demand for additional collateral. Read the issuer’s latest annual and quarterly filings to see which risks are material to that company.
Compare the risks using the right framework
| What to examine | Bank with mortgage exposure | Mortgage REIT |
|---|---|---|
| Credit quality | Mortgage and other loan delinquency, nonaccruals, charge-offs, credit-loss allowances, portfolio mix and borrower or geographic concentrations. | Borrower and collateral quality, delinquencies and defaults, risk ratings, credit-loss allowance, and any real-estate-owned assets. |
| Funding and liquidity | Deposit mix and stability, deposit costs, uninsured or brokered deposits where disclosed, wholesale-funding reliance, liquidity and net interest margin. | Repo, warehouse, securitization and other secured funding; counterparties, maturities, collateral haircuts, recourse and liquidity for margin calls. |
| Leverage and loss absorption | Regulatory capital, tangible equity, liquidity and sensitivity to losses on loans or securities. | The company’s leverage definition and level, recourse exposure, equity buffer, hedging and ability to withstand asset marks or collateral calls. |
| Earnings engine | Net interest income and margin, mortgage banking or servicing income where relevant, credit provisions and operating costs. | Asset yields relative to funding costs, realized and unrealized gains or losses, hedge results, credit losses and the capacity to sustain distributions. |
| Valuation | Price to book and price to tangible book, considered alongside profitability, capital, asset quality and earnings power. | Price relative to book value per share, considered alongside how book value is calculated, asset marks, credit losses, funding costs and leverage. |
Use these categories to organize research, not to rank companies mechanically. Accounting, portfolios and leverage differ, and the cited regulator and issuer materials do not establish one fair-value multiple that applies to every mortgage-related stock.
#1 Best Overall
Assess loan quality beyond one delinquency figure
A delinquency rate is only one point in the path from a missed payment to a realized loss. Check whether the filing distinguishes early-stage delinquency from nonaccrual, default, charge-off and recovery. Review how each measure changes over time, and compare it with the company’s own portfolio mix: loan type, borrower profile, collateral or property type, geography, and any material concentrations.
Then compare problem loans with the allowance for credit losses and the period’s provisions and charge-offs. An allowance is an estimate of expected credit losses, not a guarantee against future losses. Read the assumptions and portfolio tables behind it, and consider whether rising delinquencies, concentrated exposures or realized losses are changing the picture. For a lender holding mortgage-backed securities, examine the underlying credit exposure and the accounting treatment disclosed for those assets rather than assuming that all mortgage securities have the same risk.
Rank #2
System-wide figures can help set context but cannot substitute for issuer-level trends. The Federal Reserve Board’s Banking System Conditions report, published June 11, 2026, says aggregate U.S. commercial-bank deposits reached $19.5 trillion in February 2026. It also reports total loan delinquency of 1.6% at year-end 2025, below a long-run historical average of about 3%. Those are aggregate commercial-bank figures, not the delinquency rate or funding position of a particular mortgage company.

Trace funding, liquidity and leverage
For a bank: examine deposit stability and wholesale funding
Look at the deposit base, its composition and cost, and how those measures have shifted. Where disclosed, pay attention to uninsured and brokered deposits, as well as reliance on wholesale funding. Check the liquidity discussion for available funding sources and constraints, then relate funding costs to net interest margin and net interest income. A bank’s deposit total alone does not tell you how stable or inexpensive its funding is.
The Federal Reserve describes wholesale funding as potentially more costly and less stable than core deposits. The FDIC’s 2026 Risk Review, updated April 22, 2026, says wholesale funding declined as banks reduced Federal Home Loan Bank borrowings and brokered deposits. The review also describes credit risks as generally contained in 2025 while noting continuing weaknesses in commercial real estate and some consumer loan types. These reports describe sector conditions; they do not establish the funding or credit quality of any single bank.
For a mortgage REIT: understand collateral mechanics
Find out what funding instruments the REIT uses, whether obligations are recourse or nonrecourse, when they mature, and what collateral supports them. For repo financing, review the counterparties, haircuts and provisions that can require more collateral as asset values move. Ask whether the company reports liquidity available to meet collateral calls, and how its hedges are intended to respond to changes in rates and asset values.
Rank #4
Do not compare leverage figures until you understand each company’s definition and denominator. A company-specific illustration: AGNC Investment Corp.’s 2025 Form 10-K reports a 7.2x tangible-net-book-value-at-risk leverage ratio at December 31, 2025. That figure describes AGNC under its stated measure on that date; it is not a sector average, a target or a threshold for judging another issuer. Read the definition and reconciliation in the filing before making comparisons.
Evaluate the earnings engine and interest-rate exposure
For banks, connect asset yields and funding costs to net interest income and margin. Also account for credit-loss provisions, operating expenses, and mortgage banking or servicing income when material. For mortgage REITs, look at asset yields versus funding costs, realized and unrealized gains or losses, hedge results and credit losses. In either model, distinguish recurring earnings drivers from gains or losses that depend on market movements or accounting marks.
Interest-rate changes do not affect every part of a mortgage balance sheet in the same direction. Rates can change asset values, funding costs, margins, refinancing and prepayment behavior, and hedge effectiveness. Review the issuer’s own rate-risk discussion and sensitivity analysis, including the assumptions used. A sensitivity table is a scenario analysis, not a promise that actual results will follow that path.
If the company presents non-GAAP measures, reconcile them with GAAP figures and understand what the adjustment excludes. For a mortgage REIT, do not treat a distribution as evidence of sustainable earnings by itself: compare the distribution with the company’s disclosed earnings measures, realized results, financing costs and balance-sheet capacity.

Price-to-book and price-to-tangible-book can be useful starting points for a bank; price relative to book value per share can be useful for a mortgage REIT. Neither ratio says by itself that a share is cheap or expensive. Book value depends on asset marks, credit allowances, accounting choices and, for a REIT, the balance-sheet effects of leverage and hedging. Compare the market price with the company’s reported value while examining how that value was calculated and what could change it.

For a bank, weigh the discount or premium against asset quality, capital, profitability and the sustainability of earnings. For a mortgage REIT, also assess the portfolio’s marks, financing costs, leverage, hedge outcomes and ability to absorb losses. The available evidence does not support a universal multiple or a stock recommendation without analysis of a named issuer’s current filings and market price.
A practical filing-review sequence
- Identify the business model. In the latest annual and quarterly filings, establish the main asset types, activities and sources of earnings.
- Read portfolio and credit disclosures. Track delinquencies, nonaccruals, defaults, charge-offs, allowances and provisions over time; inspect loan or property mix and concentrations.
- Map the funding. For a bank, review deposits, deposit costs, wholesale funding and liquidity. For a mortgage REIT, review repo and securitization terms, counterparties, recourse, maturities, collateral requirements and margin-call liquidity.
- Test resilience. Read capital or leverage definitions, interest-rate sensitivity, hedging disclosures and risk factors. Consider how earnings and liquidity could respond to credit deterioration or adverse market moves.
- Assess earnings quality and distributions. Separate recurring operating results from market-driven gains and losses; reconcile company-defined non-GAAP measures with GAAP figures where applicable.
- Consider valuation last. Interpret price-to-book or price-to-tangible-book in light of the company’s asset marks, reserves, funding, leverage, profitability and earnings capacity.
This is a due-diligence framework, not a recommendation to buy or sell. The cited examples concern U.S. banks and issuers and conditions reported for 2025 or early 2026; an investment decision also depends on the particular company, share class, market price, time horizon and investor’s risk tolerance.
