The Quick Read: you replace your current mortgage with a larger jumbo loan, take the difference in cash, and pay only interest for a set number of years. The interest-only period is temporary. After it ends, the payment resets to include principal, and it can jump. Lenders size the loan from your appraised value, then test whether you can handle the higher payment.
Key Takeaways
- Interest-only lanes exist for jumbo cash-outs on a primary home, but they carry tighter ratio limits than fixed lanes.
- Cash-out leverage runs lower than purchase leverage.
- The balance does not shrink during the interest-only years.
- The real test is the payment after the reset, not the one you pay on day one.
What Is an Interest-Only Jumbo Cash-Out?
It is three features stacked on one loan. Each one changes the file.
Jumbo cash-out estimate
Enter the value, the balance, and the cash wanted; choose the occupancy and the structure; the lanes, the payment, and the reserves follow.
Editable benchmark: 7.18% as of November 5, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a jumbo cash-out refinance quote.
Illustrative starting assumptions: a $2,000,000 home value in the jumbo range, a $1,000,000 current balance, a principal residence on a thirty-year fixed structure at the current Freddie Mac conforming benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conforming benchmark, a market reference and not a jumbo cash-out refinance quote; a jumbo loan is priced by the lender at lock. The lanes shown are the wholesale cash-out lanes behind this page as of the snapshot date; the calculator reads each lane’s leverage, loan maximum by occupancy, cash-in-hand cap, and reserves as the lane table states them, and a Lendmire loan officer confirms the lane on the file. The cash available is the loan the lane allows less the balances paid off, before closing costs, which are not included; on most lanes a jumbo cash-out begins one dollar above the conforming limit for the county, and two lanes start at a stated dollar floor instead. The HELOC line is the line program’s combined loan-to-value ceiling applied to the same value and balance. Taxes and insurance are editable estimates. Licensed in sixteen states for consumer mortgages.
A jumbo loan is any loan above your county’s conforming limit, which means it begins one dollar over that limit. The conforming limit is the largest loan Fannie Mae and Freddie Mac can buy. The limit changes yearly and varies by county, so check the current figure on FHFA’s conforming loan limit page. A county gets a higher limit when 115% of its median home value exceeds the national baseline. The ceiling in the costliest counties is 150% of that baseline, per FHFA’s announcement of the limit values.
A cash-out refinance pays off your current mortgage with a bigger one. You keep the difference. Because you are borrowing against equity you already own, lenders cap leverage lower than they do on a purchase.
Interest-only means the required payment covers interest and no principal for a stated period. Your balance stays flat.
Put those together and you have a larger loan, with cash in hand, at the lowest required payment the structure allows. It works for some households. It is a poor fit for others.
How the Loan Is Underwritten, Step by Step
Here is how a file moves, in order. Across the wholesale programs Lendmire places files with, the sequence is consistent even when the numbers differ.
1. Pick the structure. Fixed, adjustable and interest-only are separate lanes. Each has its own limits.
2. Value the home. An appraisal sets your value. Past a lane’s threshold amount, two appraisals are required.
3. Size the loan. Value times the lane’s cash-out leverage sets the ceiling. Your current balance comes off the top. What remains is your cash.
4. Check credit. The headline lane starts at a 660 decision score. Other lanes may ask for more.
5. Test the ratio. Your monthly debts, including the new housing payment, are compared with verified income.
6. Count reserves. Reserves are liquid savings measured in months of your full payment. They rise as the loan amount rises.
7. Disclose and close. You receive a Loan Estimate, then a Closing Disclosure.
Lendmire’s jumbo cash-out refinance program page lays out the lanes in more detail. Every figure there, and every one here, is subject to lender guidelines and full file review. None of it is a commitment to lend.
The Numbers That Frame the Loan
Here is the envelope for the headline lane and its relatives. Each lender sets its own details inside it.
| Item | What to know |
|---|---|
| Credit | 660 decision score on the headline lane |
| Leverage | Ceilings vary by lane; several reach 89.99% CLTV and the rest stop at 80% |
| Loan size | Up to $5,000,000 on the largest lanes |
| Ratio ceiling | Fixed, adjustable and interest-only structures each carry their own ceiling |
| Cash-out | Lower leverage than a purchase; cash cap on two lanes |
Two notes on that table. LTV is loan-to-value: the loan divided by the home’s appraised value. CLTV adds any second loans on the property. Those are two different labels, and they are not interchangeable. Also, cash-out leverage is not the same as the headline leverage. Expect the cash-out figure to sit below it, and expect the cash cap on the biggest lanes to bite before the leverage does.
On the ratio ceiling, the interest-only lanes cap debt-to-income at 43%, while the adjustable lanes allow 45% and the fixed lanes allow up to 50%. That makes 43% the tightest ratio in the set. The lender is treating the structure as extra risk, so it gives you less room on debts.
How Interest-Only Differs From a Fully Amortizing Loan
| Factor | Interest-only | Fully amortizing |
|---|---|---|
| Early payment | Interest only | Interest plus principal |
| Balance in early years | Stays flat | Falls steadily |
| Ratio ceiling here | 43% | Up to 50% on fixed |
| After the opening period | Payment resets higher | Payment stays on schedule |
The lower early payment is the draw. The flat balance is the cost. You are building no equity from payments during that stretch. Your equity grows only if the home’s value rises.
What Happens When the Interest-Only Period Ends
The payment resets. Principal now has to be repaid over the shorter time that remains on the loan. That means the same balance is spread across fewer years.
The CFPB’s mortgage glossary draws a clean line here. Interest-only means scheduled payments cover just interest for a stated period. Negative amortization is different: payments fall short of the interest due, and the balance grows. Interest-only, done as described, does not grow the balance. It also does not shrink it.
Many interest-only loans are adjustable. If yours is, the interest charge can change at the same time the payment recalculates. Two moves at once can be a shock.
So ask the loan officer three things up front:
- How long is the interest-only period?
- Is the loan fixed or adjustable after it ends?
- What will the fully amortizing payment look like on my balance?
You can work out the last one using the loan documents. Do it before you sign, not after.
How Lenders Qualify You: The Payment That Counts
Qualifying is where borrowers get surprised. Federal ability-to-repay rules require a lender to make a good-faith finding that you can repay. The CFPB’s compliance guide lists eight minimum factors. They include income or assets, employment, the monthly mortgage payment, your other debts, and your debt-to-income ratio or residual income. Lenders verify these with reliable third-party records.
Interest-only loans fall outside the Qualified Mortgage category. That does not make them illegal. It means the lender has no automatic presumption of compliance and has to support its own finding. Under the QM-style calculation for interest-only loans, the payment used is the fully amortizing one, per the CFPB’s guidance. Individual programs can measure it differently, so confirm how your lane does it.
The practical lesson: do not assume you qualify on the low payment. A lender may test you on a higher payment than the one you will pay in the opening years. Ask which payment your lane uses before you commit.
“Non-QM” also does not mean “no income check.” Documentation varies by program, and some programs offer alternative paths for self-employed borrowers. Income is still verified.
Edge Cases Where the General Rule Breaks
Conforming-sized loans. A cash-out at or below the county limit can be sold to Fannie Mae or Freddie Mac. Interest-only is generally not part of that box. Interest-only cash-outs live above the limit, where each investor writes its own rules.
Government loans. FHA, VA and USDA loans generally do not offer interest-only. If you hold one, a jumbo cash-out would mean refinancing out of it.
Other occupancy. This article covers your primary home. Second homes and rental properties get different leverage by lane. If that is your situation, the lane’s occupancy rules decide the leverage, and they are tighter.
Condominiums. Two lanes accept non-warrantable condominiums, which are condo projects that fall outside standard agency rules. If you own one, the lane list shrinks.
A second loan on the home. If you have a home equity loan behind your first mortgage, the new loan has to pay it off or deal with it. That changes your CLTV, so tell your loan officer at the start.
Recent purchase. Lenders set seasoning, a waiting period between buying and cash-out refinancing. It varies by lender. Own the home for a while and more options open.
Your Right to Cancel on a Primary Home
On a refinance of your primary residence, you get a right to cancel. Per the CFPB’s rescission guidance, you have three business days, and Saturdays count. The clock starts once you have received the required notices. You must cancel in writing. Funds are released after that window passes.
This right does not apply to second homes or rentals. It also does not erase your original loan if you cancel.
Who Should Think Twice
Interest-only fits a narrower group than people assume. It tends to fit a borrower with:
- Income that is strong now and likely to stay strong or rise.
- A clear plan for the cash, such as a project that adds value.
- Reserves well beyond the minimum.
- A realistic exit: selling, paying down, or refinancing before the reset.
It fits poorly if you are stretching to qualify, if your income is uneven with no cushion, or if your exit depends on prices rising. Refinancing at the end is never a given. Values can fall. Your credit or income can change. The lender’s rules can change.
Alternatives are worth a look. A smaller cash-out on a fully amortizing loan gives you less cash and a payment that builds equity. A home equity loan or line can leave your first mortgage untouched. Each trades a different cost for a different benefit.

Frequently Asked Questions
Does interest-only let me take out more cash?
Not on its own. Cash-out is capped by leverage on the appraised value and, on the largest lanes, by a cash cap. Interest-only lowers the early payment. It does not raise those limits, and its lanes carry the tightest ratio ceiling at 43%.
Do I qualify on the interest-only payment?
Often you do not. Federal QM-style rules use the fully amortizing payment, and many programs look past the low payment too. Ask your loan officer how your lane measures it, and plan around the higher figure.
Can I take all my equity out?
No. Leverage on a cash-out is set below purchase leverage, and a cash cap applies on two lanes. Several lanes reach 89.99% CLTV and the rest stop at 80%. A lender also wants you to keep some equity in the home.
What if I cannot refinance when the period ends?
Then the payment resets on the existing loan, and you must be able to afford it. That is why an exit plan matters. Reserves, income growth, or a planned sale are the usual backstops. Do not rely on rising prices alone.
Is this available on a second home or rental?
Occupancy decides the leverage, and lanes set lower limits for second homes and rentals than for a primary home. The right to cancel also applies only to your primary residence.
If You Are Weighing This Against Keeping Your Current Loan
If you are weighing a cash-out refinance against keeping the loan you have, Lendmire can help you compare the programs and the equity each one reaches. The decision comes down to one question: can you carry the payment after the reset? If the answer is yes without leaning on future price gains, the structure may suit you.
