The Quick Read: The amount is set by a stack, not by the buyout alone. The lender adds the old mortgage payoff, the buyout payment and the closing costs. It then tests that total against a leverage cap, a loan-size cap and your single-income file. Across the wholesale jumbo programs Lendmire places files with, leverage reaches 90% on the strongest lane and loans run to $5,000,000 on the largest lanes, subject to lender guidelines. You must qualify alone.
Key Takeaways
- The buyout itself does not make a loan jumbo. The new total balance does.
- Maximum buyout = (appraised value × the lane’s leverage limit) minus the payoff, minus costs.
- The person keeping the home carries the whole balance on one file.
- The loan-size cap and the leverage cap are two different limits. The leverage cap usually binds first.
- If the number falls short, there are structures that close the gap. Pushing the leverage is not one of them.
How the Loan Amount Is Built
A buyout loan equals the old mortgage payoff plus the payment to the departing owner plus financed costs. A loan becomes jumbo when that total lands one dollar above the county’s conforming limit. The limit changes yearly and varies by county, so check it for your property.
Jumbo payment estimate
The starting figures are an example price in the jumbo range with ten percent down on a thirty-year fixed. Replace them with yours.
Editable benchmark: 7.40% as of October 15, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a jumbo loan quote.
Illustrative starting assumptions: a $1,000,000 price in the jumbo range, ten percent down on the top-leverage lane, 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 loan quote; jumbo rates are set by the lender and the lane at lock and differ from the conforming benchmark. An adjustable-rate scenario is shown at the benchmark for the whole term; the rate after the initial period is unknown. Reserve months and appraisal counts follow the lane sheet for the amount band; the automated finding may require more. Taxes, insurance and dues are editable estimates; closing costs are not included. On most lanes the conforming limit for the county decides whether a loan is jumbo at all; two lanes start at a stated dollar floor instead. Licensed in sixteen states for consumer mortgages.
The buyout can be small and the loan can still be jumbo. Say the existing balance is large and you add a modest payout. The new note is the sum of both, and that sum is what gets classified. The reverse also holds. A large payout on a home with a low balance can stay conforming.
Lendmire’s jumbo loan programs are built for loans above that line. Lendmire is a mortgage broker. It arranges these loans through wholesale lenders and does not lend itself, and every figure here is subject to lender guidelines and full file review.
The county limit comes from FHFA, which sets it by county and unit count and normally publishes a new figure in late November. Federal agencies do not cap a jumbo buyout. Each wholesale lane sets its own leverage, credit floor and reserves.
Key Terms Defined
Jumbo loan: a mortgage whose balance is above the county conforming limit.
Buyout: a payment to a co-owner for their share of the home, so one owner keeps it.
Payoff: the amount needed to clear the existing mortgage at settlement.
Leverage (LTV or CLTV): the loan balance as a percentage of the appraised value.
Reserves: liquid funds you hold after closing, counted in months of the full housing payment.
Release of liability: the lender’s written removal of the departing owner from the loan note.
What Limits the Check
Leverage binds first on most buyouts. The loan-size cap rarely does. Programs reach 90% on the headline lane, several lanes reach 89.99% CLTV, and the rest stop at 80%. Loans run to $5,000,000 on the largest lanes. Most files hit the percentage before they hit the dollar ceiling.
Here is the reverse math, in plain steps:
1. Start with the appraised value.
2. Multiply it by the lane’s leverage limit. That gives the largest total loan the lane allows.
3. Subtract the payoff of the existing mortgage from that largest total loan.
4. Subtract the costs you plan to finance.
5. What remains is the most the loan can put toward the departing owner.
How the lender classes the deal moves the cap. A buyout treated as cash-out sits at lower leverage than a purchase, and the largest lanes add a cash cap. Ask early which treatment applies, because the same facts can read differently from one lane to the next.
Taking extra cash on top of the buyout pushes the file toward full cash-out treatment. That cuts the leverage you can use.
Occupancy matters too. If the home is a second home or an investment property, leverage is set lane by lane. This article is about the home you live in.
Three Worked Scenarios
These are modeled inputs, not market data. Each figure is a percentage of appraised value.
| Scenario | Payoff | Buyout | Result |
|---|---|---|---|
| Small share, mid-priced home | 25% | 15% | 40% plus costs. May stay conforming. |
| Sibling buyout, high-value home | 30% | 45% | 75% plus costs. Fits an 80% lane. |
| Partner buyout, large balance | 60% | 35% | 95% plus costs. Over the 90% ceiling. |
The third row is the common failure. The balance is high, so the buyout can’t fit under any lane’s cap. Costs make it worse. That file needs a different structure, covered below.
Qualifying Alone
The person keeping the home has to carry the entire new balance on one set of income, assets and credit. The departing owner is not on the new note. That is the decision point for most buyouts.
The jumbo envelope is specific. The headline lane uses a 660 decision score. The fixed lanes allow a 50% ratio ceiling. The adjustable lanes stop at 45% and the interest-only lanes at 43%. Reserves are counted in months of the full payment and rise with the loan amount. Above a lane’s threshold amount, two appraisals are required.
Appraisals matter beyond the lender. A neutral appraisal fixes the value both owners split. It also removes the “my number versus your number” fight before it starts.
Support income, such as alimony or child support, helps only when it is documented and expected to continue. Self-employed buyers should expect the lender to look closely at how income is documented.
Siblings, Partners and Other Co-Owners
The rules read “co-owner,” not “spouse.” The paperwork changes by relationship.
| Relationship | What helps the file | Common snag |
|---|---|---|
| Siblings who inherited | Inheritance often relaxes ownership timing | Uneven shares, one sibling unreachable |
| Unmarried partners | Both on title, written agreement | No decree to define the split |
| Non-family co-owners | Clean agreement, neutral appraisal | Disputed value, uncooperative signer |
Fannie Mae’s heirs’ property guidance says a limited cash-out refinance can fund a buyout of one or several co-owners. It also waives the 12-month ownership seasoning for recent heirs. That is a conforming rule. Jumbo lenders set their own, but many borrow the same logic.
Unmarried partners lack the divorce framework, so the written agreement carries more weight. It should state the value, the payout and how proceeds are paid.
Where the General Rule Breaks
Five edge cases come up most.
Occupancy history. Some lenders ask for proof that both owners lived in the home. A co-owner who moved out years ago can trip this.
Title position. At least one borrower on the new loan is normally on title at application. Fannie Mae’s guide lists exceptions for inheritance, a legal award in divorce and trust beneficiaries.
Release from the old loan. A quitclaim deed moves title. It does not remove anyone from the mortgage note. Only a payoff or a lender-approved release does that. A refinance pays off the note, which is why it solves this.
Listed homes. A home listed for sale generally has to come off the market before the loan funds.
Condos. Non-warrantable condominiums are accepted on two lanes. A buyout on a condo that fails standard review narrows the lane choice.
When the Buyout Exceeds the Check
If the stack goes over the cap, there are structures to review. None is guaranteed, and each changes the file.
- Stage the buyout. Pay part now and part later, once the balance or income changes.
- Buy out a smaller share. A partial buyout lowers the total and may drop the loan under jumbo.
- Bring cash. Cash toward the payout lowers the loan percentage.
- Use a second lien. A home equity loan or line leaves the first mortgage in place. It adds a second payment that the lender counts.
- Family financing. A family note may carry extra disclosure, and the lender may count it in your ratios.
- Look at a different lane. Lanes differ on leverage, cash caps and ratios. A lane that fits one file can miss another.
What the Decision Looks Like in Practice
A clean buyout file moves in a set order.
1. Get an appraisal that both owners accept.
2. Write down the payout and have all parties sign the agreement.
3. Confirm title, the owners’ occupancy history and any liens.
4. Run the stack: payoff plus buyout plus costs against value.
5. Check your ratio, score and reserves against the lane, then pick the lane.
6. Review the Loan Estimate and Closing Disclosure carefully when they arrive.
Settlement pays off the old mortgage, pays the departing owner, pays costs and conveys title to you. Equity is not the same as cash, so costs and reserves reduce what is actually available.
Frequently Asked Questions
Can a jumbo loan cover the whole buyout?
Sometimes. It covers the buyout only if payoff, buyout and costs fit under the lane’s leverage cap and your income carries the new balance. Programs reach 90% on the headline lane, with loans to $5,000,000 on the largest lanes. Subject to lender guidelines and full file review.
Does a buyout make my loan jumbo?
No. The new total balance does. A large balance plus a small payout can be jumbo. A modest balance plus a large payout can stay conforming.
Can the person leaving stay on the loan?
Generally not. Lenders expect the person keeping the home to qualify alone, and the departing owner is not on the new note. A payoff releases them. A lender-approved release or assumption is the alternative.
Is a buyout treated as cash-out?
It depends on the lender and the facts. Some treat a qualifying buyout more like a limited refinance, and others treat it as cash-out. Cash-out sits at lower leverage than purchase, and the largest lanes add a cash cap.
What if my partner and I are not married?
It can work. Both of you should be on title, and the written agreement carries more weight because no decree defines the split. Your income must carry the whole balance.
