Pros and cons of interest-only mortgages

Written by Samantha SheltonNMLS 1647301Updated October 2026

An interest-only mortgage lets you pay only the interest for a set opening period, so your payment drops and your balance doesn’t move. On a $400,000 loan priced at an illustrative 6.5%, that’s about $2,167 a month instead of $2,528 on a standard 30-year fixed loan, roughly $362 in freed-up cash flow, and $0 in principal paid.¹

Hypothetical example, not an offer. Actual rates, costs and payments vary.

The bill for that trade arrives twice. Over the same 10 years, the 30-year borrower retires about $60,900 of principal, more than the $43,400 of cash flow the interest-only borrower kept, and when the interest-only period ends, the untouched balance has to amortize over the 20 years left in the term, pushing the payment to roughly $2,982.

There’s a regulatory dimension too. Because an interest-only loan lets you defer repayment of principal, it can’t satisfy the Qualified Mortgage payment-structure test in Regulation Z, 12 CFR § 1026.43(e)(2)(i)(B). That puts it in non-QM territory, where guidelines are written lender by lender instead of by an agency rulebook. Learn how interest-only mortgages actually work, what the reset costs, who they genuinely fit, and what it takes to qualify.

Key takeaways:

• Pro, roughly 14% off the payment, not 40%: On a $400,000 loan at an illustrative 6.5%, interest-only runs about $2,167 versus $2,528 fully amortizing about $362 a month, a smaller gap than most borrowers expect.
• Con, $0 in equity and about $65,600 more interest: The balance stays flat for the entire interest-only period, and repaying that same $400,000 over the 20 years left after a 10-year interest-only window costs roughly $65,600 more in total interest than a straight 30-year loan.
• It will not buy you more house: Federal ability-to-repay rules make lenders qualify you on the payment that repays the loan over the term remaining at recast. About $2,982 in this example, higher than the $2,528 you’d be qualified on for a plain 30-year loan.

Hypothetical example, not an offer. Actual rates, costs and payments vary.

What is an interest-only mortgage?

An interest-only mortgage is a loan whose scheduled payments cover only the interest for a defined opening period, which means the amount you owe does not go down with each payment, the Consumer Financial Protection Bureau’s definition, and the whole product in one sentence. Five-year and 10-year interest-only periods are the common structures in today’s market, but the length is set by your note, not by any rule.

You don’t have to take anyone’s word for the dates. Federal disclosure rules require the Projected Payments table on your Loan Estimate to break out each period when the principal-and-interest payment changes and to label an interest-only payment with the words “only interest” (12 CFR § 1026.37(c)). A 30-year loan with a 60-month interest-only period shows up as “Years 1-5” and “Years 6-30,” side by side, before you sign anything.

Two precision points get muddled online. Interest-only is not negative amortization: your balance stays flat, it does not grow. The pre-2008 payment-option ARM that let unpaid interest pile onto the balance is a different, largely extinct product. And a home equity line of credit also has an interest-only draw period, but a HELOC is open-end credit, excluded from § 1026.43 outright, so the rules below don’t govern it.

The mechanics are just mortgage amortization with the front end switched off; the CFPB explains how principal and interest split across a payment. For the structure itself, start with our guide to interest-only mortgages. This page is the decision framework; our companion piece on interest-only mortgage risks and benefits goes deeper on mechanics and failure modes.

What are the advantages of an interest-only mortgage?

The advantages are real but narrower than the marketing suggests, and every one of them is a cash-flow benefit rather than a wealth benefit.

• A lower payment for a defined window about 14% lower here: The interest-only payment is your balance times your rate, divided by 12. In our $400,000 example that’s $2,167 against $2,528 fully amortizing, roughly $362 a month, about $43,400 across a 10-year period. Note the size: 14%, not the 40% or 50% borrowers assume, because at higher rates most of an early payment is interest anyway.
• Principal becomes optional, and can’t be penalized: Your required payment is the interest; anything above that is your choice, month to month. And because a prepayment penalty is only permitted on a loan that is a Qualified Mortgage and meets three further conditions (12 CFR § 1026.43(g)(1)), a consumer-purpose interest-only mortgage on your home generally can’t carry one. Where penalties are legal at all, they’re capped at 2% of the balance prepaid in years one and two, 1% in year three, and are prohibited after three years.
• It matches lumpy income to a lumpy payment: Commissioned salespeople, business owners, and borrowers paid largely in an annual bonus can carry the interest-only floor through thin months and drop a lump sum on principal after a good quarter. A structural fit a fixed amortizing payment can’t replicate. See fixed-rate mortgage benefits and drawbacks for the other side of that trade.
• The tax treatment doesn’t change: Interest on a loan used to buy, build, or substantially improve your home is deductible within the same acquisition-debt limits as any mortgage, $750,000 ($375,000 if married filing separately) for debt secured after December 15, 2017, and $1 million for grandfathered older debt, per IRS Publication 936 (2025 edition).² Keep it in proportion: paying an extra $65,600 in interest to deduct a fraction of it is not a strategy.

The CFPB’s explainer on interest-only loans covers the same ground from the regulator’s side.

What are the disadvantages of an interest-only mortgage?

The disadvantages compound, which is what makes this a decision rather than a preference. Each one below is measured against the same $400,000 comparison.

• You end year 10 about $60,900 behind on equity: Payments build nothing. The 30-year borrower’s balance falls to roughly $339,100 while yours sits at $400,000, so your only equity is appreciation and your down payment. If values fall instead, you have no cushion between your balance and the home’s worth, and the cash flow you kept, about $43,400, doesn’t cover the $60,900 of principal you skipped.
• The recast raises the payment about 38%, more at lower rates: When the interest-only period ends, the full balance amortizes over whatever term is left. Ten years of interest-only on a 30-year loan means repaying $400,000 across 20 years instead of 30: about $2,982 versus $2,167, a jump of roughly $816 a month. Counterintuitively, the percentage jump is larger at lower rates, because a smaller interest payment is a smaller base to grow from across rates from 4% to 8%, the same structure raises the payment by roughly 25% at 8% and roughly 82% at 4%.
• Total interest runs about $65,600 higher: Over 30 years the interest-only path costs roughly $575,800 in interest against $510,200 on the straight 30-year loan, $975,800 paid versus $910,200. You’re renting the same $400,000 for a decade before you start buying it back.
• Your exit plan is doing more work than you think: Most interest-only borrowers plan to sell or refinance before the recast. The CFPB’s warning is blunt: don’t assume you can, because values fall and circumstances change. If the loan is also adjustable, the rate reset and the principal reset can land in the same year, see adjustable-rate mortgage pros and cons. If your note ends in a lump sum instead of a recast, you’re looking at balloon mortgage risks and benefits.

Hypothetical example, not an offer. Actual rates, costs and payments vary.

Interest-only vs. a 30-year fixed loan: the numbers on a $400,000 loan

Here’s the whole argument in one table. Both loans are $400,000 over a 30-year term at an illustrative 6.5%; the interest-only loan has a 10-year interest-only period. The rate is an assumption chosen to make the arithmetic comparable, not a quote or a market rate.¹

Hypothetical example, not an offer. Actual rates, costs and payments vary.

That last row is the one almost every article gets wrong, so read it twice. Under the ability-to-repay rule, a creditor evaluating a standard fixed-rate loan uses fully amortizing payments over the loan term. For an interest-only loan, 12 CFR § 1026.43(c)(5)(ii)(B) requires the creditor to use the greater of the fully indexed rate or the introductory rate, plus substantially equal principal-and-interest payments that repay the loan over the term remaining as of the recast date, the 20-year payment, not the 30-year one, and certainly not the interest-only one.

So an interest-only mortgage does not stretch your buying power. It’s the opposite: you’re underwritten on a payment about $454 a month higher than the 30-year borrower beside you, then permitted to pay less than that for 10 years. The benefit is monthly flexibility after closing, not a bigger approval. Anyone selling it as a way to afford more house is describing a product that stopped existing in 2014. (Business-purpose investment loans sit outside Regulation Z under 12 CFR § 1026.3(a), which is why investor interest-only products behave differently.)

What does the CFPB’s own interest-only example show?

The official interpretation of Regulation Z works the qualifying math on two $200,000 loans, each with a 30-year term and five years of interest-only payments, according to the CFPB’s commentary to 12 CFR 1026.43(c)(5)(ii)(B). The recast falls on the 60th payment, so principal is repaid over the 300 months left, and the lender must test that higher payment.

Hypothetical example, not an offer. Actual rates, costs and payments vary.

Hypothetical example, not an offer. Source: CFPB, official interpretation of 12 CFR 1026.43(c)(5)(ii)(B), comments 2.i and 2.ii, amounts as rounded by the CFPB; the last column is calculated from those figures.

Two lessons follow. First, the length of the interest-only window drives the size of the jump. For example, the same $200,000 at the same 7% with a 10-year window would leave 20 years to repay, and the same method gives about $1,551, roughly 33% above the $1,167 interest-only payment. Second, an adjustable rate and an interest-only period stack: in the CFPB’s adjustable example, the payment rises three times in five years before any principal is due.

As Samantha Shelton puts it, “The maximum somebody can qualify for and the amount they actually feel comfortable paying every month are not always the same number. And I don’t live in your house.” With an interest-only loan, the number to test against your own budget is the payment after the recast. The mortgage payoff calculator and our guide to mortgage recasting show what extra principal does to that payment.

Who should consider an interest-only mortgage, and who shouldn’t?

The fit is narrow, and it turns on one question: is the lower payment a tool, or is it the only reason the house works? Three profiles where interest-only earns its place:

• Irregular income with a strong annual total: If 60% of your pay arrives in two months of the year, an interest-only floor plus voluntary principal payments matches the loan to the income instead of fighting it.
• A documented, dated exit inside the window: A relocation you already know about, a vesting schedule, or a property you intend to sell, a plan with a date on it, not a hope the market cooperates.
• A higher-return use for the cash: Business capital or matched retirement contributions can outrun the roughly $65,600 of extra interest. That’s an investment thesis, not a mortgage feature, and it only works if the money actually gets invested.

And three where it’s the wrong tool:

• The payment is what makes the house affordable: The recast arrives on schedule whether or not your income grew. If $2,167 is a stretch, $2,982 is a default.
• You plan to stay 20 or 30 years: Long tenure is exactly where the extra interest and delayed equity compound against you; compare the alternatives in our loan types and programs guide first.
• A small down payment: With no principal paydown, a thin equity position stays thin, and a flat or falling market leaves you unable to sell or refinance out of the very reset you were counting on.

How did the rules for interest-only loans change after 2006?

From 2003 through 2005, alternative mortgage products, mostly interest-only and payment-option adjustable-rate loans, grew from less than 10% of residential mortgage originations to about 30%, the Government Accountability Office reported in GAO-06-1021 (September 2006). Based on 2005 securitization data, the same report found that about 47% of interest-only ARMs originated in California.

The OCC, the Federal Reserve Board, the FDIC, the Office of Thrift Supervision and the NCUA issued the Interagency Guidance on Nontraditional Mortgage Product Risks (71 FR 58609, October 4, 2006). It told institutions to evaluate repayment at the fully indexed rate assuming a fully amortizing schedule, but a footnote based that schedule on the full term: a loan with a 5-year interest-only period and a 30-year term would be calculated on a 30-year amortization schedule. In OCC Bulletin 2006-41, the agencies wrote that marketing materials and disclosures typically focused borrowers on the lower initial payments and either discounted the later payments or assumed the borrower would be able to sell or refinance.

That federal guidance did not reach state-licensed mortgage companies, so on November 14, 2006, the Conference of State Bank Supervisors and the American Association of Residential Mortgage Regulators issued parallel guidance for them, according to the CSBS highlights. Per that summary, providers should judge whether a borrower can repay by final maturity at the fully indexed rate, and it reports that these loans were often underwritten with less stringent income and asset verification and combined with simultaneous second liens.

The years that followed tested those assumptions. By the end of 2010, 29.7% of interest-only loans originated from 2005 to 2007 were or had been seriously delinquent, according to the CFPB’s January 2019 Ability-to-Repay and Qualified Mortgage Rule Assessment Report, against 35.5% of short-reset ARMs and 27.1% of loans with limited or no documentation from the same years.

The CFPB’s ability-to-repay rule, issued in January 2013, took effect on January 10, 2014, the assessment report says. Under it, the qualifying payment is the remaining-term payment described above, not the full-term payment the 2006 guidance used. In the Bureau’s survey of lenders, 16 of the 87 lenders that described in writing what changed in their business (18%) reported discontinuing products with an interest-only feature, while other lenders reported that they continue to offer interest-only loans as non-QM loans.

Hypothetical example, not an offer: on this page’s $400,000 illustration at 6.5%, the 2006 full-term method would have tested a 30-year payment of about $2,528, while the current rule tests the 20-year payment of about $2,982, the same $454 gap shown in the comparison table.

What it takes to qualify for an interest-only mortgage

Qualifying is the third filter, and it ends most of these conversations. Because an interest-only loan defers principal, it can’t be a Qualified Mortgage, so no agency rulebook sets the credit score, reserve, or down payment minimums. Those come from the individual lender or the investor buying the loan, and they vary meaningfully.³ Three things are worth being precise about:

• Non-QM is not subprime, and it is not unregulated: The lender still must make a reasonable, good-faith determination that you can repay the loan (12 CFR § 1026.43(c)(1)), weighing eight specific factors including income, assets, employment, other debts, your debt-to-income ratio or residual income, and credit history. What non-QM removes is the lender’s legal safe harbor, not the underwriting.
• Most interest-only loans are jumbo or portfolio loans: A loan is jumbo when it exceeds the conforming loan limit for its county, a moving target, not a fixed dollar amount. FHFA set the 2026 baseline at $832,750 for a one-unit property, with a ceiling of $1,249,125 in the highest-cost counties (150% of baseline). Check your county’s limit, then see our jumbo and non-QM hub for how these files get underwritten.
• Portfolio guidelines are genuinely lender-specific: A lender keeping the loan on its own books sets its own terms, which is why no honest article can print universal qualifying numbers for interest-only. Comparing three lenders on the same file is the only way to see the real spread.

Because Align is a broker, we can place interest-only structures through partner lenders many retail banks don’t offer, and price them against every alternative in our loan types and programs guide in the same conversation. Worth comparing while you shop: why APR differs from the note rate, since interest-only pricing often carries costs the note rate alone won’t show.

Can any qualified mortgage carry interest-only payments?

Not under the statute or its portfolio and small-creditor versions. 15 U.S.C. 1639c(b)(2)(A)(i) defines a qualified mortgage as a loan whose regular payments may not increase the principal balance or, outside a balloon exception, allow the consumer to defer repayment of principal. The portfolio safe harbor in 1639c(b)(2)(F), for insured banks and credit unions with less than $10,000,000,000 in assets including affiliates, still requires a loan that “does not have negative amortization or interest-only features.” Per the CFPB’s 2019 assessment report, Small Creditor Balloon QM loans may not have interest-only features either.

The government programs rule it out too. An FHA-insured mortgage must provide for payments to principal and interest to begin not later than the first day of the month following 60 days from execution, under 24 CFR 203.17(c). A VA loan maturing beyond five years must be amortized with approximately equal payments and a principal reduction at least annually, under 38 CFR 36.4310(a). Align Lending is not affiliated with or endorsed by HUD, FHA or the VA. Compare FHA loans, VA loans and a lender’s own portfolio loan, plus our jumbo loan tips; the DTI guide shows how the post-recast payment enters your ratio.

What does the Loan Estimate show on an interest-only loan?

Beyond the Projected Payments table, 12 CFR 1026.37 puts the feature in three more places:

• Product name: If any regular payment may be applied only to interest, the product must be described with an “Interest Only” feature, listed ahead of the product type (1026.37(a)(10)(ii)(B) and (iii)).
• Loan Terms: Under “Can this amount increase after closing?”, the principal and interest line must state that only interest is required for a period and give the due date of the last payment of that period (1026.37(b)(6)(iii)).
• Comparisons: “In 5 Years” shows the principal scheduled through the 60th month as “Principal you will have paid off” (1026.37(l)(1)), which reflects no scheduled principal on a loan with five or more years of interest-only payments.

What should Michigan borrowers know about interest-only loans?

Lenders reported 158,499 originated closed-end loans on Michigan properties in 2024, excluding reverse mortgages and lines of credit, and 4,758 of them, 3.0%, had interest-only payments, according to the public HMDA data lenders file under the Home Mortgage Disclosure Act. Among consumer-purpose first liens, 30.2% of loans above the conforming limit carried the feature, against 1.8% of loans at or below it.

Source: 2024 Home Mortgage Disclosure Act data for Michigan, originated loans, from the FFIEC HMDA Data Browser, tabulated for this article from the interest-only payment field reported by lenders under Regulation C; shares are of loans reporting the field, rounded.

Michigan law adds two checks that matter to an interest-only borrower:

• Refinancing before the recast: Many interest-only borrowers plan to refinance or sell before principal comes due, so a prepayment charge is the cost to check first. For a first-lien loan on a single-family home, other than an FHA, VA or USDA loan, MCL 438.31c(2)(c) caps that charge at 1% of the amount prepaid in the first 3 years and allows none after that; subsection (5) limits that section to lenders approved under the National Housing Act or supervised by a state or federal agency. Ask which rule a prepayment clause relies on before you count on refinancing out of the interest-only period.
• Refinancing into or out of an interest-only loan: Michigan’s Consumer Mortgage Protection Act, MCL 445.1634, bars false, deceptive or misleading statements about a borrower’s ability to qualify. Under MCL 445.1632(d) it reaches loans on a principal dwelling other than the loan used to buy it, so it applies to a refinance of the home. For a purchase loan, the federal payment rule described above is the check.
• Property taxes: Payments on this page exclude taxes and insurance, often paid through an escrow account. In Michigan, a home’s taxable value is capped while one owner holds it. The year after it sells, that cap comes off and taxable value resets to the state equalized value, which is half of the assessor’s estimate of market value, not automatically half of what you paid (Michigan Department of Treasury). The Michigan property tax calculator shows the bill to plan for.

FAQ: Interest-only mortgages

Here are answers to common questions about interest-only mortgages.

Are interest-only mortgages a good idea?

For a narrow group, yes. They fit borrowers with documented rising income, lumpy commission or business cash flow, or a firm dated plan to sell or refinance inside the interest-only window. They’re a poor idea when the lower payment is what makes the house affordable, because the reset arrives on schedule regardless of whether your income grew as planned. Our deeper look at interest-only mortgage risks and benefits covers the failure modes in detail.

What happens when the interest-only period ends?

The loan converts to full principal-and-interest payments, and the remaining balance amortizes over the time left in the term. On a 30-year loan with a 10-year interest-only period, the principal is repaid across 20 years instead of 30, which raised the payment by about 38% in our $400,000 example, and by roughly 25% at an 8% note rate up to roughly 82% at 4%. Your other options are selling or refinancing, neither of which is guaranteed. See mortgage amortization for how the recast math works.

Can you pay off principal during the interest-only period?

Yes, and doing it is the single best defense against payment shock. Every extra dollar lowers both the future amortized payment and the interest accruing in the meantime. On a consumer-purpose interest-only mortgage there is generally no prepayment penalty to worry about, since 12 CFR § 1026.43(g) permits them only on Qualified Mortgages meeting further conditions, but confirm it in your own note, especially on an investment property. Our guide to interest-only mortgages shows where to look.

Do interest-only mortgages have fixed or adjustable rates?

Most are adjustable, with a fixed introductory period that often lines up with the interest-only window, so two changes can land near the same time. Note that the 2/2/5 and 5/2/5 cap structures you’ll see quoted are conventions, not rules: your actual caps are set by your note, and most new adjustable loans are indexed to SOFR now that LIBOR has been discontinued. Compare the margin and cap details across lenders using adjustable-rate mortgage pros and cons.

What credit score do you need for an interest-only mortgage?

No federal minimum exists; the lender or investor sets it. Borrowers have tended to be strong: in the CFPB’s 2019 assessment report, 2014 conventional purchase loans with interest-only payments averaged a credit score of about 771 against 755 for all loans, a loan-to-value ratio of about 69% against 82%, and a DTI of about 33% against 30%. See what counts as a good credit score.

Are interest-only loans more common on investment properties?

On business-purpose loans, yes. In Michigan’s 2024 HMDA data, 1,651 of 8,205 originated business-purpose closed-end loans, 20.1%, had interest-only payments, against 2.1% of consumer first liens on principal residences. Consumer-purpose first liens on investment properties carried the feature in only 11 of 2,457 cases. Our guides to buying an investment property and refinancing an investment property cover how those loans are underwritten.

Can I refinance my interest-only mortgage with the same lender?

Yes. Under 12 CFR 1026.43(d), the current holder or its servicer can refinance an interest-only loan into a standard mortgage without the full repayment-ability analysis if the new payment is materially lower (10% or more always qualifies), the written application arrives no later than two months after the recast, and you have no more than one payment over 30 days late in the prior 12 months and none in the prior six. See refinancing eligibility.

What is the Total Interest Percentage on a Loan Estimate?

It is the total interest you would pay over the loan term as a percentage of the loan amount, shown in the Comparisons table under 12 CFR 1026.37(l)(3). Interest-only loans run higher because principal is repaid later. Hypothetical example, not an offer: on this page’s $400,000 illustration, about $575,800 of interest is roughly 144% of the loan, against roughly 128% for the straight 30-year loan. See fixed vs. adjustable-rate mortgages.

The bottom line on interest-only mortgages

An interest-only mortgage buys cash flow and sells equity. On a $400,000 loan at an illustrative 6.5%, it frees about $362 a month for 10 years, roughly $43,400, while leaving you about $60,900 behind on principal, raising the payment about 38% at recast, and adding about $65,600 in total interest over 30 years. It won’t get you approved for more house, because ability-to-repay rules make lenders qualify you on the post-recast payment. It fits irregular income and dated exit plans; it does not fix affordability.

Hypothetical example, not an offer. Actual rates, costs and payments vary.
