The Quick Read: You replace your current mortgage with a new, larger jumbo loan, take the difference in cash, and choose a structure where the required payment covers interest only for a set stretch. Lenders judge the file on equity, credit, income, reserves and the appraisal. Many also test whether you could handle the bigger payment that starts when the interest-only period ends. Every program figure below is subject to lender guidelines and full file review, and none of it is a commitment to lend.
What You Are Actually Asking For
You are asking for three things at once. A new first mortgage that pays off your old one. Extra cash on top. And a payment structure that delays principal repayment.
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.
Each piece has its own rules. Stacked together, they make a narrower product than a plain refinance. Not every lender offers all three, and the ones that do set their own limits.
In the wholesale programs these files go through, the interest-only option is one structure among fixed and adjustable. Lendmire’s jumbo cash-out refinance program page covers how those lanes are organized. Lendmire is a mortgage broker. It arranges the loan through wholesale lenders and does not lend or approve.
Key Takeaways
- Interest-only lowers the required payment for a set term, but your balance does not shrink during that term.
- Qualifying means clearing a tighter ratio cap on interest-only lanes than on fixed loans.
- Cash-out runs at lower leverage than a purchase, and your appraisal sets the ceiling.
- Plan for the payment jump at the end of the term before you sign, not after.
How to Qualify and Apply, Step by Step
Step 1: Size the loan before you talk to anyone. Start with your home’s likely value and your current payoff. Then compare the new loan you want against the leverage limits below. If your current balance already sits near the cap, there is little cash to take.
Step 2: Check the age of your current loan. Conventional agency rules often want a waiting period on cash-out. Those are conforming rules. Jumbo lenders set their own waiting periods, which may be stricter or looser.
Step 3: Gather your documents. Expect to provide:
- Income proof: W-2s, pay stubs and tax returns if you are an employee, or the lender’s alternative documentation if you are self-employed.
- Asset and reserve statements.
- Your current mortgage statement.
- Homeowners insurance.
- Title work.
- A written explanation of how you will use the cash.
Step 4: Apply and review your Loan Estimate. This is the standard consumer process. Check the loan structure line closely. It should show when the interest-only period ends and what the payment becomes afterward.
Step 5: Order the appraisal. The appraised value sets the maximum loan, so it decides how much cash you can take. Larger loans can require two appraisals.
Step 6: Close, then wait out the cancellation window. On a refinance of your primary home, you have a right to cancel. Funds move after that window passes.
What Lenders Check, and What Interest-Only Changes
The table below shows where the interest-only choice bites. The first column is the underwriting factor. The other two show what the lender reviews and how interest-only shifts it.
| Factor | What the lender checks | What interest-only changes |
|---|---|---|
| Credit | Decision score and history | Floors can be higher than fixed |
| Leverage | New loan vs. appraised value | Cash-out sits below purchase leverage |
| Ratio | Monthly debts vs. income | Tighter cap on interest-only lanes |
| Reserves | Months of full payment in the bank | Scale up with the loan amount |
| Appraisal | Value, condition, comps | Two appraisals above a lane’s threshold |
The Numbers That Frame the Search
Across the wholesale lanes these loans use, the headline lane starts at a 660 decision score. Leverage on those lanes tops out at 90% LTV, which is the loan-to-value ceiling. Several lanes reach 89.99% CLTV, meaning combined loan-to-value when a second lien is counted, and the remaining lanes stop at 80%. Loans reach $5,000,000 on the largest lanes. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Keep two cautions in mind. First, those leverage figures are ceilings, and cash-out runs at lower leverage than a purchase. A cash cap applies on the two largest lanes. Second, the headline credit floor belongs to the headline lane. The interest-only lane has its own guidelines, so confirm its score floor on your file.
The ratio is where interest-only gets tighter. It is your total monthly debts divided by your gross monthly income. Fixed lanes cap it at 50%, adjustable lanes at 45%, and interest-only lanes at 43%.
Against the fixed cap, that is a seven-point gap. For a high-balance borrower with a car loan, a second property and a large new balance, it matters.
How Is the Interest-Only Payment Actually Tested?
Many programs do not qualify you on the low interest-only payment alone. They test whether you could carry the payment that includes principal once the interest-only period ends.
There is a federal reason behind this. The CFPB’s compliance guide for the ability-to-repay rule says a General Qualified Mortgage may not have an interest-only feature. So an interest-only jumbo is a non-QM loan. That is allowed. It simply means the lender must document its own good-faith judgment that you can repay.
For you, this means two things. You will not get a break on income just by choosing interest-only. And lenders differ, so ask each one which payment they use for the ratio. Do not assume.
Key Terms Defined
Jumbo loan: A mortgage above the conforming limit for your county and unit count.
Cash-out refinance: A new mortgage larger than your payoff, with the difference paid to you.
Interest-only period: The set stretch when your required payment covers interest and no principal.
Fully amortizing payment: A payment that covers interest and principal, so the balance reaches zero by the end of the term.
Non-QM: A loan outside the federal Qualified Mortgage definition, underwritten to the lender’s own documented standards.
Reserves: Cash and liquid assets left in your accounts after closing, measured in months of your full payment.
What Makes a Loan “Jumbo” in Your Area?
A loan is jumbo when it is above the conforming limit for its county and unit count. FHFA sets those limits each year. A baseline applies to most of the country, and high-cost areas get a higher ceiling. Alaska, Hawaii, Guam and the U.S. Virgin Islands have their own special limits.
So there is no single national jumbo number. A loan that is jumbo in one county can be conforming in another. FHFA’s county lookup shows your figure, and it tends to update each year in late November. A jumbo loan begins one dollar above your county’s limit.
Which Limit Binds First?
On a cash-out interest-only file, one of several limits stops you before the others. Which one depends on your situation. Here is the usual order of suspects.
1. The ratio cap. At 43% on interest-only lanes, this often binds before leverage does, especially if you carry other debt.
2. The cash-out leverage cap. It sits below purchase leverage. If your balance is already high against value, this one stops you.
3. The cash cap. On the two largest lanes, a separate limit applies to how much cash you can take.
4. Reserves. These rise with the loan amount. A big loan can fail on liquidity even when income is strong.
5. The appraisal. A value that comes in lower than expected shrinks everything above.
The ratio cap and the leverage cap are the two to test first. Run both before you commit to a loan amount.
A Worked Example, in Percentages
Picture a homeowner whose current loan equals about half of the home’s value. They want cash for a renovation and a lower required payment for a few years.
The new loan amount cannot exceed the lane’s cash-out leverage cap applied to the appraised value. Subtract the payoff and the closing costs from the new loan. What remains is the cash. If the appraisal comes in below what the borrower expected, the cap shrinks and so does the cash.
Now the payment. During the interest-only term, the required payment covers interest on a larger balance. It can still land below what a fully amortizing payment on the old balance would have been. Then the term ends. Principal must now be repaid over the shorter remaining time, and the payment steps up.
The OCC’s consumer pamphlet warns that payments can rise sharply after the interest-only period. Plan for that number now. Your Loan Estimate shows it.
What Happens at the Reset?
At the end of the interest-only term, you have four paths:
- Pay the higher amortizing payment out of income.
- Refinance into a new loan.
- Sell the home.
- Pay down principal early, if the loan allows it.
Only the first is fully in your hands, and the last is too if your loan permits early paydown. A refinance later depends on your credit, your income and your home’s value at that time. If prices fall, your options narrow. Interest-only does not build equity through payments, so appreciation does the work.
A refinance also starts a new loan. It does not extend your old interest-only clock. You restart on whatever term the new loan carries.
Adjustable interest-only loans add another layer. With an adjustable-rate loan, interest-only payments can rise even during the interest-only period. Fixed lanes avoid that second shock.
Where the General Rule Breaks
A few edge cases trip people up.
Government-backed loans. Interest-only structures are generally not part of FHA, VA or USDA programs. This is a jumbo and non-QM feature.
Rate-and-term versus cash-out. A refinance with no cash out is treated differently. Jumbo programs also define cash-out their own way, so confirm how your lender classifies a small cash-back amount.
Second homes and rentals. Occupancy decides the leverage, and the limits differ from a primary residence. Second homes and investment properties have their own limits, so check them before you assume the primary-home figures apply.
Your right to cancel. The CFPB says you have until midnight of the third business day after closing to rescind. Saturdays count as business days, and Sundays and legal holidays do not. If you cancel, you still owe your original loan. Waiving the right is allowed only for a genuine personal financial emergency, so it is not a routine shortcut. If the required disclosures were missing or wrong, the window can stretch up to three years.
No safe harbor. Qualified Mortgages come with a legal presumption of compliance for the lender. Non-QM loans do not.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Common Mistakes That Sink This Switch
- Qualifying on the low payment in your head. Many lenders do not.
- Ignoring the ratio cap. At 43%, a car loan and a second mortgage can matter more than income growth.
- Borrowing to the leverage ceiling. A soft appraisal then cuts your cash.
- Skipping reserves. Large balances need more months of full payment in the bank.
- Missing the waiting period. A recent purchase or refinance can delay a cash-out.
- Treating the term as permanent. The interest-only period ends. Have the exit worked out first.
- Overlooking prepayment terms on your current loan. Check your note for any penalty. Many owner-occupied loans do not have one, but some do.
Who This Structure Fits, and Who Should Skip It
Interest-only suits borrowers with strong but uneven income, a clear plan for the cash, and a realistic exit before or at the reset. It can also fit someone who expects to sell inside the interest-only term.
It fits poorly if the lower payment is the only thing making the budget work. If you cannot carry the amortizing payment, the reset is a problem you have scheduled in advance. A fixed lane may serve you better, even at a higher required payment, and it carries the loosest ratio cap of the three at 50%.

Frequently Asked Questions
Do I qualify on the interest-only payment or the full payment?
It depends on the program. Many lenders test the fully amortizing payment, because the loan must be repayable over its term. Ask which payment drives the ratio before you apply. The ratio cap on interest-only lanes is 43%.
What credit score do I need?
The headline jumbo lane starts at a 660 decision score. Interest-only lanes carry their own guidelines, and a higher score usually opens more leverage and better terms. Final eligibility depends on the full file.
How much cash can I take out?
Cash-out runs at lower leverage than purchase, and the largest lanes also apply a cash cap. Your cash equals the new loan minus your payoff and closing costs, so the appraisal decides most of it.
Can I convert my current loan to interest-only without refinancing?
Usually not directly. Most borrowers move into a new loan with the interest-only structure, and that new loan starts its own term. Some lenders offer modifications, but that is a separate request from a cash-out refinance.
What happens when the interest-only period ends?
The payment steps up to include principal over the remaining term. You can pay it, refinance, sell, or make extra principal payments beforehand. Refinancing later is not assured, since it depends on your credit, income and home value at that point.
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. Many jumbo owners find that the real decision is not whether to take interest-only, but whether the reset fits the plan they already have for the home.
