The Quick Read: A lender does not pull the number off a chart. It tests the property’s value, how you will use the home, the size of the loan, the strength of your file, and the cash you hold after closing. The down payment is whatever those tests leave uncovered. Programs differ, so the final percentage is a lender-specific result, subject to lender guidelines and full file review.
Key Takeaways
- The loan is sized as a percentage of the lower of the price or the appraised value. The down payment is the rest.
- Occupancy sets the leverage. A second home generally gets less leverage than a primary home.
- Bigger loans bring tighter limits, more reserves, and sometimes a second appraisal.
- Reserves are counted after your down payment is spent. Too big a check can cost you the reserve test.
- Nothing here is a commitment to lend. Each home gets its own appraisal and its own approval.
What Makes a Loan “Jumbo” on a Second Home?
A loan is jumbo when it starts one dollar above the conforming limit for the county where the home sits. That limit changes yearly and differs by county, so the same loan can be jumbo in one place and conforming in another. Check your own county’s limit with the Federal Housing Finance Agency, which sets the baseline and the high-cost rules.
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.
Jumbo loans sit outside the agency boxes. No agency rule sets a jumbo down payment. Each wholesale lender writes its own guidelines. Across the programs Lendmire places files with, the headline lane starts at a 660 decision score and reaches up to 90% leverage. Several lanes top out just under that, at 89.99% combined loan-to-value (CLTV), which adds every loan on the home together. The rest stop at 80%. The largest lanes go to $5,000,000. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Those are ceilings, not promises. A second home rarely sits at the top of the range. Occupancy, loan size and reserves all pull the number down from there. Lendmire’s jumbo loan programs lay out the lanes you can compare.
The Five Inputs a Jumbo Lender Weighs
Every second-home file runs through the same five questions:
1. Value. What is the home worth, and what did you agree to pay?
2. Occupancy. Will you use it personally, and is it your primary home, a second home, or an investment?
3. Loan amount. Which lane does the size land in, and what does that lane demand?
4. Borrower strength. Decision score, debts against income, and how the file is documented.
5. Liquidity. What cash remains after the down payment and closing costs?
Weak spots in one input can be offset in another, but only to a point. A strong score does not erase thin reserves on a large loan.
The Sizing Sequence, Step by Step
Here is how the number gets built. The order matters, because each step can shrink what the next step allows.
| Step | What the lender checks | What moves the number |
|---|---|---|
| 1. Value | Lower of price or appraisal | A low appraisal |
| 2. Occupancy | Primary, second home or investment | Your stated use |
| 3. Loan tier | The lane for your amount | Size, condo type, structure |
| 4. Borrower | Score, ratio, documentation | Score tier, debt load |
| 5. Reserves | Months of payment left over | Loan size, other properties |
Step 1: Start with value. The lender uses the lower of the purchase price or the appraised value. If the price is higher, the extra is your cash. Above a lane’s threshold amount, two appraisals may be required, and the lane sets that threshold.
Step 2: Classify occupancy. Occupancy is a statement you make to the lender, and it drives leverage. Primary, second-home and investment occupancy each carry their own leverage within a lane. Lenders usually define a second home as a single dwelling you will use yourself for part of the year, suitable for year-round living, and not run as a rental or timeshare. The Fannie Mae Selling Guide is the public benchmark for that definition. Jumbo lenders set their own versions.
Step 3: Place the loan in a lane. Fixed, adjustable and interest-only structures each carry their own leverage and ratio limits. The fixed lanes allow debts up to 50% of income, with 45% on the adjustable lanes and 43% on the interest-only lanes. Non-warrantable condos, meaning projects that do not meet standard agency project rules, fit only two lanes.
Step 4: Test the borrower. Federal ability-to-repay rules require lenders to weigh eight factors and verify them with reliable records. Those include your income or assets, the new payment, other mortgage payments, other debts, your debt-to-income ratio, and your credit history. The CFPB’s ability-to-repay summary lists all eight. The rule does not set a down payment. That part is lender policy.
Step 5: Test reserves. Reserves are measured in months of the full housing payment, and the months rise with the loan amount. More on this below.
A Worked Example (Modeled Assumptions, Percentages Only)
Run the numbers with a modeled purchase. Treat the price as 100%. Assume the lane allows 80% leverage on a second home. These inputs are assumptions for illustration, not a quote. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Case A: the appraisal matches the price. The loan is 80% of the price. Your down payment is 20%.
Case B: the appraisal lands 4% below the price. The lender uses 96% of the price as the value. Eighty percent of that is 76.8% of the price. Your cash is now 23.2% of the price, not 20%.
The lender did not change its percentage. The appraisal shrank the dollar loan, and you cover the gap. Many buyers miss this until the appraisal is back. If you can, hold a cushion above the planned down payment, or ask the seller about adjusting the price.
Where the Cash Can Come From
Lenders care about where the money came from as much as how much there is. Expect to document every large deposit. A rough guide:
| Source | Typical treatment |
|---|---|
| Savings, checking | Usually fine, with statements |
| Brokerage account | Usually fine, with statements |
| Sale of another home | Fine with a settlement statement |
| Gift funds | Often limited on jumbo loans |
| Equity pulled from your primary | Possible, but changes your debts |
Gift rules are tighter on many jumbo lanes than on agency loans, so ask early. If you plan to fund the purchase with equity from your main home, Lendmire’s piece Can Jumbo Cash-Out Funds Be the Down Payment on a Second Home? walks through it. Cash-out loans carry lower leverage than purchase loans, and two lanes cap the cash taken out. Equity compensation is another common source. Lendmire’s article How a Jumbo Cash-Out Counts RSUs Toward a Second Home Down Payment covers how unvested and vested shares are treated.
Why Reserves Can Undo a Bigger Down Payment
Here is the catch. Reserves are counted after the down payment and closing costs leave your account. Put in a very large down payment, and you may drop below the reserve line.
Lenders count reserves in months of the new home’s full payment: principal, interest, taxes, insurance and association dues. Agency guidelines say the home you are buying, your primary residence, and funds you cannot yet access do not count as reserves. Read the Fannie Mae reserve rules for the benchmark. Jumbo lanes follow a similar spirit with their own month counts, and the months climb with the loan amount.
Owning other financed homes adds more to the pile. Your primary mortgage payment also lands in your debt ratio next to the new one. Two housing payments, two sets of taxes and insurance, and any association dues all sit in the ratio at the same time. Thinking about the debt ratio before you pick a price saves rework later.
Where the General Rule Breaks
A few edge cases change the sizing:
- Condos and resort areas. Lenders may require lower leverage on certain condo projects. Non-warrantable condos fit only a couple of lanes.
- Mixed personal and rental use. Federal commentary on the CFPB’s Regulation Z uses a 14-day personal-use test to decide whether a loan counts as consumer credit. Its own example is a beach house used for a month and rented the rest of the year. That test is not a lender’s second-home test. Lenders apply their own occupancy rules, and agency guidelines bar rental pools and arrangements that hand occupancy control to a management firm.
- Rental income. Under agency guidelines, rent is not used to qualify a second home. Do not plan on counting it.
- More than one unit. Agency guidelines limit second homes to one unit.
- Government loans. By industry convention, FHA, VA and USDA loans are for primary homes, so they are not options here.
- Number of financed homes. The more mortgaged properties you carry, the more reserves and scrutiny you will see.
- Equity from the primary home. Cash-out leverage runs lower than purchase leverage, so the source of funds can change the sizing.
If the home is part-time rental, say so. Occupancy decides the leverage, and a misstated use is a bigger problem than a lower loan amount. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Bigger Down Payment or Smaller: What You Trade
| Choice | What you gain | What you give up |
|---|---|---|
| Larger down | More cushion, a smaller loan | Less cash left for reserves |
| Smaller down | More cash kept liquid | A bigger loan, tighter lane limits |
| Under a lane threshold | Fewer requirements, perhaps one appraisal | May need more cash up front |
Pricing and requirements can shift with leverage, and a lower loan-to-value often gives a lender more comfort. The right balance depends on your reserves, not just the lender’s minimum. Sometimes a mid-sized down payment with strong reserves reads better than a maximum check with nothing behind it. Since each lender sets its own rules, a broker can compare how different wholesale lanes treat the same file.
Questions to Ask and Documents to Gather
Ask your loan officer:
1. Which lane does my loan amount fall into?
2. What leverage applies to a second home in that lane?
3. At what loan amount do I need two appraisals?
4. How many months of reserves are required, and what counts?
5. Are gift funds or cash-out proceeds allowed for the down payment?
6. Is the condo project on your approved list?
Gather your recent statements for every account holding down payment funds, a record of the source of any large deposit, your primary mortgage statement, and details on any other financed property.

Frequently Asked Questions
How much do I have to put down on a jumbo second home?
It depends on the lane, the loan amount and your file. Programs reach up to 90% leverage at the top, but a second home typically gets less than that headline. Several lanes stop at 80%. A lender reviews your file before giving a number.
Can I use an FHA loan to buy a second home?
No. By industry convention, FHA, VA and USDA loans are limited to primary residences. Second-home buyers look at conventional and jumbo options.
Can gift money cover my down payment?
Sometimes. Agency guidelines permit gifts on second homes with conditions on how much of your own money goes in. Jumbo lenders often restrict gifts further, so confirm with the lender before you move any funds.
What happens if the appraisal comes in low?
The loan shrinks, because the lender applies its percentage to the lower value. You make up the difference in cash, or you renegotiate the price. Keeping a buffer above your planned down payment protects you.
Can I rent the home out and still call it a second home?
Lenders expect you to use it personally and keep it available for that use. Rental pools and management arrangements that control occupancy are a problem. If you plan to rent it out regularly, tell the lender, because it could be classified differently and carry different leverage.
