The Quick Read: The cash you bring to a move-up purchase is three separate piles: the down payment, the closing costs, and the reserves you keep afterward. Most buyers focus on the first pile and get surprised by the other two. The right split depends on the loan size, the lender’s guidelines, and how secure your income and your home sale are. Put everything into the down payment and you may look weaker, not stronger.
Key Takeaways
- A loan is jumbo because of the loan amount, not the price of the house.
- Down payment and cash to close are not the same number. Closing costs and reserves come on top.
- Reserves are money left over after closing. They cannot double as down payment.
- Selling first, buying first, or overlapping the two changes how much cash you need to show.
- A bigger down payment can shrink the loan, but it can also drain the cushion a lender wants to see.
What Makes a Loan Jumbo for a Move-Up Buyer?
A loan is jumbo when it exceeds the conforming limit for the county where the home sits. A jumbo loan begins one dollar above that line. The limit is set county by county and changes every year, so this article does not quote it. Look up your county’s number before you pick a price range.
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: 7.32% as of October 22, 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.
That is why price alone tells you little. Two buyers can pay the same price. One brings more cash and lands under the limit. The other brings less and lands over it. Same house, different loan category.
Jumbo is a wholesale lane that sits outside the standard agency box, and the guidelines are set lender by lender. Across the wholesale programs Lendmire places files with, the common envelope looks like this:
- A 660 decision score on the headline lane.
- Leverage up to 90%. Several lanes reach 89.99% combined loan-to-value, and the rest stop at 80%.
- Loan amounts up to $5,000,000 on the largest lanes.
- A 50% debt-to-income ceiling on the fixed lanes, 45% on the adjustable lanes, and 43% on the interest-only lanes.
- Reserves and appraisal requirements that grow with the loan amount. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Lendmire’s jumbo loan programs page walks through the lanes in more detail. Every figure here is subject to lender guidelines and full file review. None of it is a commitment to lend.
Here is the catch for move-up buyers. Lower leverage lanes ask for more down. Higher leverage lanes ask for stronger files and often more reserves. You are choosing among lanes, not just picking a number.
Key Terms Defined
Down payment: The part of the price you pay up front instead of borrowing.
Cash to close: The total you wire at closing. It is the down payment plus closing costs, minus deposits already paid, seller credits, and other adjustments.
Reserves: Liquid money you still hold after closing. Lenders measure it in months of your full housing payment.
Full housing payment: Principal, interest, property taxes, homeowners insurance, and any association dues, added together.
DTI (debt-to-income ratio): Your monthly debts divided by your monthly income. Lenders cap it by program.
Recast: A reset of your payment after you make a large lump-sum payment on the balance. Whether it is offered depends on the loan and the servicer.
CLTV (combined loan-to-value): All loans secured by the home, added together, divided by the home’s value.
The Three Piles of Cash
Think of your savings as three buckets. Each one does a different job.
| Pile | Spent or kept? | What it covers |
|---|---|---|
| Down payment | Spent at closing | Your share of the price |
| Closing costs | Spent at closing | Lender, title, appraisal, recording, prepaid items |
| Reserves | Kept after closing | Months of full payments as a safety net |
The Consumer Financial Protection Bureau says closing costs typically run 2% to 5% of the purchase price, not counting the down payment. On a large price, that is a large number. It is also the pile buyers forget.
The same agency defines your maximum available cash for closing in plain steps. Start with total savings and investments. Subtract money for other goals, moving, furnishings, renovations, and an emergency cushion. It describes that cushion as usually three to six months of expenses. Jumbo lenders often want more than that, and the requirement rises with the loan amount.
Then check the form. The Loan Estimate shows estimated cash to close. It starts with the down payment and closing costs, then subtracts deposits, seller credits, and other adjustments. That is the figure that has to be in your account and documented.
One more point on down payments. Federal mortgage rules do not set a minimum, according to the CFPB’s own rule summary. The minimum you face comes from the lane you choose. A lane that reaches 90% leverage asks for as little as 10% down. A lane that stops at 80% asks for at least 20%. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
How Do Lenders Count Reserves?
Lenders take your verified assets, subtract what you need to close, and see what is left. Then they divide the remainder by your full monthly housing payment. The answer is months of reserves.
Step by step:
1. Add up your verified liquid assets.
2. Subtract the down payment and closing costs.
3. Apply the lender’s treatment to less liquid assets. Retirement accounts and investments are often counted at a discount, depending on the lane.
4. Divide what remains by the full payment, including taxes, insurance, and association dues.
5. Compare the result to the lane’s reserve requirement for your loan amount.
Two things trip people up. First, the same dollar cannot serve twice. Money used for the down payment is gone. Second, reserves are measured against the new payment, not the old one.
Reserves scale with the loan amount. A bigger loan means more months. The lane’s guidelines set the exact number, so ask for it before you decide how much to put down.
Sell First or Buy First?
Your sequence changes your cash picture more than most buyers expect. In practice, this is where move-up files get complicated.
| Sequence | Old home’s payment | Cash tied up | Main risk |
|---|---|---|---|
| Sell first | Gone before you buy | Proceeds held until you close | Temporary housing gap |
| Buy first | Counts in your DTI | Savings fund the purchase | Carrying two homes |
| Overlap, same period | Often counted | Depends on timing | A slipped sale date |
If you buy first, the lender usually counts the old mortgage payment in your DTI. That runs into the 50%, 45%, or 43% ceiling, depending on the lane. A buyer with strong income can absorb it. A buyer near the ceiling may not.
If you sell first, your net proceeds become cash. But the money only counts once it is in your account and documented. A sale scheduled to close after your purchase does not fund your purchase.
Picture a buyer with a contract on the old home and a contract on the new one. The sale is expected to close first. The lender may still ask the buyer to qualify on a plan that works if the sale slips. That is the stress test you should run yourself.
Down Payment vs. Reserves: How Do You Decide?
Neither one wins every time. Here is the trade-off.
| Item | More down payment | More reserves |
|---|---|---|
| Loan size | Smaller | Larger |
| Monthly payment | Lower | Higher |
| Liquidity after closing | Thinner | Stronger |
| Lane options | May open an 80% lane or drop under the county limit | Often needs a lane with higher leverage |
| Best for | Steady income, short cash needs | Variable income, planned expenses |
Lean toward a bigger down payment if:
- Your income is stable and well documented.
- You expect little spending after the move.
- Your old home is already under contract.
- Putting more down moves you into a lane you prefer.
Lean toward more reserves if:
- Your income varies from year to year.
- You are a single earner in the household.
- You plan renovations or furnishing right after you move.
- Your home sale has not closed or could net less than expected.
A lender does not reward a big down payment that leaves you with nothing. A file with solid reserves can look stronger than a file with a larger down payment and a thin account. This is the point most online guides skip.
A Cash Stack Worked Through in Percentages
Skip the dollars and use the percentages. Say a buyer is looking at a home priced well above the county’s limit. Three plans, three results.
Plan A, minimum down on a high-leverage lane. The buyer puts down 10% and pays closing costs in the CFPB’s 2% to 5% range. Cash out the door is roughly 12% to 15% of the price. Reserves come from whatever is left. The loan is large, so the reserve requirement is large. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Plan B, 20% down. The buyer puts down 20%. Cash out the door rises to roughly 22% to 25% of the price. The loan is smaller. Reserves are required on a smaller payment, but the buyer has less cash left over. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Plan C, enough down to land under the county limit. The loan may drop into conforming territory. That can change the overlays and the lane. The cost is more cash out at closing.
Now stress the plan. Suppose the old home sells later than planned. Suppose it nets less than expected. Suppose taxes or association dues come in higher than the estimate. Each one either shrinks your cash or raises the payment your reserves are measured against.
A good plan survives the second scenario, not just the first. If one delay breaks the plan, bring less to the table and keep more in the bank.
Should You Put Down Enough to Avoid Jumbo?
Sometimes. Not always.
Dropping under the county limit can be worth it when you are only a little over. The Federal Housing Finance Agency sets the conforming limits yearly. The formula allows higher limits in high-cost counties and for multi-unit homes. Many buyers who assume they need a jumbo loan do not, so check your county first.
Use this test:
1. Find the gap between your planned loan and the county limit.
2. Ask what it costs in cash to close that gap.
3. Check what is left for reserves afterward.
4. If the reserves still clear the requirement and your emergency cushion is intact, closing the gap can make sense.
5. If it drains you, keep the jumbo loan and keep the cash.
Mortgage insurance is part of the picture. On conventional loans, borrower-paid insurance can usually be cancelled on request once the balance reaches 80% of the original value, with conditions such as a good payment history and no junior lien, per the CFPB. Whether a given jumbo lane uses insurance or builds the cost into the loan is lane-specific. For the longer view, see Lendmire’s piece How Much Waiting to Avoid PMI Costs on a Move-Up Conventional Loan.
Where the General Rule Breaks
Rules of thumb hold until they do not. These are the cases where they stop working.
A second appraisal. Above a lane’s threshold amount, the lender requires two appraisals. That adds a cost and a second chance for the value to come in low. The loan is sized to the lower of price and appraised value, so a low appraisal can mean more cash from you.
Condos. Two lanes accept non-warrantable condominiums. Most lanes do not. If you are moving into a condo, confirm that early.
Cash-out on the old home. Some move-up buyers think about pulling cash from the old home to fund the new one. Cash-out sits at lower leverage than purchase, and the largest lanes put a cash cap on it. Plan around that.
Loan-type structure. Fixed, adjustable, and interest-only lanes have different ratio ceilings. The same file can pass on one and fail on another.
QM status. Many jumbo loans are not Qualified Mortgages. That does not make them unsafe. Lenders must still document your ability to repay. The CFPB says that some lenders choose to make only QMs, which is a lender choice, not a federal block.
Using Sale Proceeds and Recasting
One common plan is to put less down at purchase, then pay down the balance with proceeds from the old home. If the loan allows a recast, the payment resets to the lower balance.
Two cautions. Recast availability depends on the loan and the servicer, so ask before you rely on it. And the lump sum has to come from somewhere. A sale that nets less than expected shrinks the plan. For a different angle on a related decision, see Lendmire’s piece How Much a Refinance Costs vs PMI for Move-Up Conventional Loan Buyers for move-up buyers.
Mistakes That Shrink Your Cash
- Moving money without a paper trail. Large unexplained deposits get questioned. Keep statements that show where funds came from.
- Counting the same dollars twice. Down payment money cannot also be reserves.
- Forgetting closing costs. Budget the CFPB’s 2% to 5% range, not zero.
- Opening new credit before closing. New accounts change your DTI and can disrupt the file.
- Assuming the sale will close on time. Plan for a slip.
- Draining everything for a lower payment. A smaller loan helps only if you can still handle surprises.
Pre-Application Cash Checklist
- Gather two months of statements for every account you plan to use.
- Note the source of any large deposit.
- Find your county’s conforming limit.
- Ask what the lane requires in reserves at your loan amount.
- List your expected spending after the move.
- Decide how much cushion you want beyond the lender’s minimum.
- Write down what happens if your old home sells late or for less.

Frequently Asked Questions
Is my down payment the same as cash to close?
No. Cash to close adds closing costs and subtracts deposits, seller credits, and adjustments. The Loan Estimate shows the estimate. Reserves sit on top of that and stay in your account.
Can I count sale proceeds from my old home?
Only once the money is in your account and documented. A sale that has not closed does not fund your purchase. If the sale closes after the purchase, the lender looks at whether you can qualify and close without it.
Do I have to sell first?
No. You can buy first, but the old home’s payment usually counts in your DTI, and you must show cash and reserves for the new home. Subject to lender guidelines, buying first works best with strong income and a healthy cushion.
What counts as reserves?
Liquid assets left after closing, measured in months of your full housing payment. Retirement and investment accounts may count at a discount depending on the lane. The amount required rises with the loan size.
Can I put less down and recast later?
Maybe. Recasting depends on the loan and the servicer, and you need a lump sum to make it work. Ask before you plan around it, and do not assume the sale will net what you hope.
