A jumbo loan amount is the mortgage balance, not the price on the listing. In Park City and the rest of Summit County, that balance is jumbo when it sits above the conforming line for the property's unit count. Price, the cash you bring, and that county line are the three numbers that decide the label before anyone talks about approval.
The math is simple and the result is not a promise. Subtract available cash from the contract price, then compare the remainder with the current county limit. Income, debts, reserves, and the appraisal can still shrink what a lender will consider. Nothing here is an approval, a rate, or a commitment to lend.

Start with the price you would actually write, not a neighborhood average. Then list only the cash you can use at closing without emptying the accounts a lender may want left over. The gap between those two figures is the working jumbo loan amount.
Use the same order every time:
Seller credits reduce cash due. They do not automatically reduce the loan if you choose to finance closing costs instead. A gift can change the cash line only after the lender accepts the donor and the paper trail. Until that review happens, leave the gift out of the worksheet.
A $2,400,000 Deer Valley purchase with $600,000 of buyer cash produces a $1,800,000 balance before financed costs. That balance is above the 2026 one-unit county line, so the file is jumbo even though part of the price is paid in cash. Change the cash and the label can change. Change only the marketing name of the house and it does not.
Try the same house at three prices before you fall in love with one. At $1,900,000 with the same $600,000 cash, the balance is $1,300,000 and still above the one-unit line. At $1,700,000 with that cash, the balance is $1,100,000 and may sit under the line. The house did not change category. The cash and the price did.
Write the numbers in dollars, not percentages, until the end. A 20 percent down payment on $2,400,000 is $480,000, which leaves a $1,920,000 balance. A 25 percent down payment is $600,000 and leaves $1,800,000. Both are jumbo in this example. The percentage sounds larger than the dollar gap, so the dollar gap belongs on the worksheet.
Keep one column for facts and one column for guesses. The list price is a fact. A hoped-for seller credit is a guess until the contract says so. A gift from a parent is a guess until the lender accepts the donor. Building the offer on the guess column makes the jumbo loan amount look smaller than the file you can actually submit.
This worksheet answers a narrower question than a full affordability review. For the income, debt, and payment side, read how much house a Park City jumbo borrower can afford. Use that guide after the price-to-loan step, not instead of it.
Direct answer: For 2026, FHFA set the one-unit conforming limit at $832,750 in most counties and $1,249,125 in the highest-cost ceiling. Its county data puts Summit County at $1,150,000 for one unit. A balance above the matching unit limit is jumbo. A balance at or under it can still be a conventional loan.
Confirm the live county file before you rely on a blog figure. FHFA publishes the current values on its conforming loan limit page. The agency announced the 2026 baseline on November 25, 2025. County values can differ, and a new file replaces the old one.
Unit count is part of the test. A second Summit County source that republishes the FHFA file lists 2026 limits of $1,150,000 for one unit, $1,472,250 for two, $1,779,600 for three, and $2,211,600 for four. A lender still has to accept the property and the occupancy. A higher unit limit is not permission to borrow that amount.
| Worksheet line | What to enter | What it changes |
|---|---|---|
| Contract price. | Use the offer price, not the list price. | This is the starting point. |
| Buyer cash. | Enter the down payment you can document. | This lowers the balance. |
| Financed costs. | Add only costs the lender allows. | This can raise the balance. |
| County limit. | Use the limit for the unit count. | This sets the jumbo or conforming label. |
| Reserves. | List the cash left after closing. | This stays separate from the loan. |
The Summit County breakdown, including why the county sits above the national baseline, is in the 2026 Summit County jumbo loan limits guide. A statewide view of the same limit is in what a jumbo loan means in Utah. Neither page builds the offer worksheet.
Do not borrow a limit from a different county because the listing says "greater Park City." A Wasatch County cabin and a Summit County cabin can sit near each other and use different lines. The address on the contract controls the lookup. A resort name, a ski-school boundary, or a mailing city does not.
Also match the limit to the property you are actually buying. A single house uses the one-unit line. A legal two-unit property uses the two-unit line only if the lender agrees it is two units. A lock-off room, a basement suite, or a listing that says "in-law apartment" is not enough. Ask the lender which column applies before you treat the higher number as room to borrow.
Refresh the figure when the offer is real. Limits are annual, and a contract written near the new year can cross a publication date. If your worksheet still shows last year's line, redo the subtraction. A balance that was jumbo in December is not automatically jumbo in January, and the reverse is also true.
Cash at the closing table and cash left in the bank do different jobs. The first number reduces the jumbo loan amount. The second number is a reserve. Spending the reserve to enlarge the down payment can make the balance smaller and the file weaker at the same time.
Down-payment customs on large loans are often described as a range, not a rule. Many Park City jumbo files are discussed around 10 to 20 percent down, and a lender overlay can ask for more. That range is an illustration of how files are commonly structured. It is not a promise that 10 percent will be accepted on a given home.
Run two versions of the same offer. In the first, put the larger cash pile into the down payment. In the second, keep several months of housing cost in reserve and accept a larger balance. Then ask which version the lender can actually review. The smaller loan is not always the stronger file.
For a closer look at cash due at closing, use the Park City jumbo down payment guide. For the money that must remain after closing, use the jumbo reserve guide. This page only shows how those choices move the loan balance.
Separate earnest money from the down payment on the worksheet. Earnest money is usually part of the cash you bring, not a second pile. Counting it twice makes the jumbo loan amount look too small. A lender credit is the same kind of trap. It may lower cash due and leave the loan balance unchanged.
Retirement accounts need a third line. Money you could borrow from a 401(k) is not the same as money already in a checking account. Some lenders will not count a loan against retirement savings as the down payment. Others will count vested balances only as reserves. Until you ask, leave that money off the cash line that reduces the loan.
Business funds need the same caution. A transfer from a company account can be a large deposit that has to be explained. It can also be money the business still needs for payroll. If the cash is not clearly yours to spend, do not use it to shrink the balance on the offer you submit tonight.
The worksheet balance is only a candidate. A condo, a condotel, or a home with a strict rental rule can face a project review that a detached house does not. New construction and unusual mountain homes can need a closer appraisal. If the appraisal comes in below the contract price, the lender sizes the loan off the lower value unless you bring more cash.
Occupancy changes the review too. A primary home, a second home, and an investment property are not the same file, even at the same price. A house you will use on ski weeks is not automatically a primary residence. Say which one it is before you compare quotes.
The occupancy difference is explained in the second home versus primary residence guide. Buyers planning a ski place can also read the Park City second home buying guide. Keep the loan-amount math here, and use those pages for the occupancy rules.
A low appraisal changes the subtraction. Suppose the contract is $2,400,000 and the opinion of value is $2,250,000. Many lenders size the loan from the lower number. Your $600,000 cash no longer covers the same share of the contract, because the gap between price and value has to be handled too. You can renegotiate, bring more cash, or walk away. The worksheet should show all three before you are under that pressure.
Association costs belong next to the price even though they are not part of the loan. Dues, special assessments, and rental limits do not change the arithmetic of price minus cash. They can change whether that balance is financeable. A pretty loan amount on a project the lender cannot review is not a usable offer.
Once the balance is on paper, the lender tests whether the payment fits. Debts, credit history, and the stability of income all sit beside the price. A large down payment does not erase a high debt load. A strong asset statement does not erase income the lender cannot document.
Self-employed buyers, bonus earners, and buyers paid in stock often need a longer paper trail than a salaried buyer. Bank-statement programs are one possible path, and they have their own limits. They are not a workaround you can assume. Ask which documents the lender needs before you set a short closing date.
Credit overlays vary by lender. One may review a score that another will not, and a large balance can bring a tighter standard. Read the Utah jumbo credit score guide for that comparison. It does not calculate your loan balance.
A pre-approval conversation is the right moment to test the worksheet, not the moment a loan exists. Bring the offer price, the cash you can use, and the reserve you want to keep. The Park City jumbo pre-approval guide covers that sequence. If timing is the worry, the jumbo approval timeline is a separate planning tool.
Ask for the test in writing. A useful question is whether this balance is jumbo, and what cash is still required after reserves. "What is the most I can borrow?" is a weaker question. The first question uses your offer. The second invites a generic maximum that ignores the house. A maximum without a property is not the jumbo loan amount you should write into a contract.
Bring two prices if you are still negotiating. A lender can often say whether $2,200,000 and $2,400,000 land on different sides of the county line once your cash is fixed. That answer is still conditional. It can keep you from raising an offer into a loan structure you have not prepared for.
Self-employed buyers should add one more page to the stack. A year of business bank statements, a recent profit-and-loss statement, and a short note on any large deposit will not set the loan amount. They stop the cash line from being a surprise later. The Park City bank-statement mortgage guide explains that documentation path. It is a support page, not the worksheet.
Bring your price and cash figures to a Park City lender.
No. The loan amount is the price minus the cash you bring, plus any costs you finance. Two buyers can write the same Park City price and need different loan amounts because their cash is different.
It can. For 2026, the one-unit Summit County conforming limit published from FHFA data is $1,150,000. A balance at or under the limit for that unit count is not jumbo just because the house is expensive. Confirm the current FHFA file before you write the offer.
Sometimes. If extra cash pulls the balance to or under the county limit, the loan may no longer be jumbo. You still need the lender to accept the property, the occupancy, and the remaining reserves. Crossing under the limit is not an approval.
The price-minus-cash formula is the same. The underwriting is not. A second home or investment property can face a different down-payment and reserve review than a primary home at the same balance.
Not before you test reserves. A smaller loan can look cleaner on the worksheet and weaker in underwriting if no cash remains after closing. Ask the lender to compare both versions.
Put the offer price, the cash you can document, and the current county limit on one page. If the balance is above the line, plan for a jumbo review and keep reserves separate. If it is under the line, confirm that the property and occupancy still fit a conforming loan.
