The Quick Read: You show reserves by documenting liquid, verified assets that remain after your down payment and closing costs are paid. Equity in an unsold home does not count until the sale closes and the proceeds are documented. So other accounts have to carry the reserve test. Whether the old home’s payment also counts against your income depends on its sale status, and that is a separate test.
If you are buying a bigger home before the old one sells, you are working two tests at once. One test asks whether you have enough cash left after closing. The other asks whether your income can carry the payments. Most buyers blur them together. Keep them apart and the file gets much easier to plan.
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.
What Are Reserves, Exactly?
Reserves are liquid or near-liquid assets you still hold after the mortgage closes. The Fannie Mae Selling Guide defines them that way, and jumbo lenders borrow the concept. Lenders count them in months of your full housing payment: principal, interest, taxes, insurance, and association dues.
That last part trips people up. One month of reserves is not one mortgage payment. It is the whole payment, including the pieces that never touch the lender.
Three pools of money sit in every purchase file:
| Pool | What it does | Counts as reserves? |
|---|---|---|
| Funds to close | Down payment and closing costs | No |
| Reserves | What remains after closing | Yes, if verified |
| Old-home proceeds | Net cash from the sale | Only after closing and documentation |
The same dollar cannot do two jobs. Money used for the down payment is gone. Money used for closing costs is gone. Reserves are what is left over. Cash to close comes out of your assets first, and the reserve test runs on the balance.
Why Jumbo Reserves Run Heavier
A jumbo loan starts above the county’s conforming limit. The FHFA sets those limits by county and unit count, so check your own county instead of assuming a national number. Because Fannie Mae and Freddie Mac don’t buy these loans, each lender sets its own rules.
Across the wholesale jumbo programs I place files with, reserves are measured in months of the full payment and rise with the loan amount. The headline lane works with a 660 decision score and leverage up to 90%. The largest lanes reach loans of $5,000,000. Higher loan amounts and higher leverage generally mean more reserve months. Exact month counts vary by program, so I won’t pretend there is one universal number. Every figure here is subject to lender guidelines and full file review.
If you want the program overview first, Lendmire’s jumbo loan programs page lays out the lanes.
How Does the Old Home Change Your File?
The old home’s status decides how the lender treats its payment. There are three states, and each produces a different file.
| Old-home status | Payment in your debt ratio? | Reserve effect |
|---|---|---|
| Sold and closed | No, it is gone | Net proceeds may count as assets, with a Closing Disclosure |
| Under contract, not closed | Depends on contingencies | Lender may add reserves for the old payment |
| Listed, no contract | Yes, both payments count | Heaviest reserve load, if offered at all |
The public baseline is Fannie Mae’s rule. If your current home is pending sale but won’t close before the new purchase, both payments must be counted. The exception is an executed sales contract with the buyer’s financing contingencies cleared. Then the old payment does not have to be counted.
Jumbo lenders often copy that logic and add conditions. A common overlay: even when the old payment is excluded from your ratio, the lender may ask for extra reserves against it. That moves the burden from monthly income to cash in the bank. A listing alone does not make the payment disappear. Some programs may offer a no-contract path, but expect heavy added reserves.
Two tests, two levers
Your debt ratio tests income. Reserves test cash. Counting the old payment squeezes your ratio, and the lanes I work with cap that ratio at 50% on the fixed lanes (45% on adjustable and 43% on interest-only). Excluding the payment relieves the ratio but may raise the reserve ask. Knowing which test you are failing tells you which fix applies.
What Counts as Reserves and What Doesn’t
Verified, liquid assets count. Unverified or borrowed money generally does not. Here is the baseline, drawn from Fannie Mae’s guidance, with the caveat that your jumbo lender may value assets more conservatively.
| Asset | Treatment |
|---|---|
| Checking, savings, money market | Counts, with statements |
| Stocks and mutual funds | Valued from the latest statement, net of margin |
| Retirement accounts | Vested portion only, if withdrawals are allowed |
| Vested stock options | May count through statement valuation |
| Non-vested stock options | Never count |
| Seller credits (interested-party contributions) | Cannot meet reserves |
| Unsold-home equity | Does not count |
Depository accounts are verified with statements, typically the most recent two months. Unverified funds are not acceptable. Retirement funds count only to the extent they are vested, and the account must allow withdrawals regardless of employment status. You do not have to actually withdraw the money to use it for reserves. The Fannie Mae FAQ also says interested-party contributions can’t be used for reserves.
Your entire 401(k) balance is not automatically in play. Neither is a stock grant that has not vested.
Large Deposits and Moving Money
A large deposit, under the Fannie Mae baseline, is a single deposit above 50% of your monthly qualifying income. On a purchase, if you need those funds, you document where they came from. The lender must also look into any sign of borrowed funds.
This is where last-minute shuffling hurts. Moving money between your own accounts is fine, but each move leaves a trail the underwriter follows. Move funds early, keep statements clean, and keep a record of every transfer. Liquidating a brokerage account the week before you apply invites sourcing questions you can avoid.
Worked Example: Two Buyers, Same New Home
Both buyers are buying a home at the same price with the same percentage down. Both have the same verified savings. The difference is the old home.
Buyer A closes first and carries both homes. Her old home is listed with no contract. Both payments count in her debt ratio, so her income has to carry two housing payments. The lender may also want extra reserves tied to the old payment, stacked on top of the new loan’s own reserves. Her file is the heaviest on both tests.
Buyer B has a signed contract on his old home. The buyer’s financing contingency is cleared. The old payment can drop out of his ratio under the baseline logic. His income test gets easier. The lender may still ask for some reserves against the old payment, but far fewer than Buyer A faces.
Now the balance walk-through. Start with total verified liquid assets. Subtract the down payment. Subtract closing costs. What remains is the number measured against the reserve requirement. If the old home’s equity was in the starting figure, take it out. It is not liquid yet. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
This is where double-counting bites. A buyer who counts the same savings toward closing and toward reserves will find the file short at final review. Run the subtraction in order, every time.
Document Checklist
Gather these before you apply:
- Two most recent months of statements for every account used
- The most recent quarterly statement for brokerage and retirement accounts
- Vesting schedules for any stock compensation or retirement plan
- The listing agreement, if the old home is on the market
- The executed purchase contract on the old home, if you have one
- Written confirmation that the buyer’s financing contingencies are cleared
- Explanations and source documents for any large deposit
- Property tax, insurance, and association dues for the old home
The contract and the cleared contingencies are the documents that unlock the old-payment exclusion. If the buyer’s financing contingency is still open, the exclusion generally is not available under the baseline rule.
Timeline: Where Reserves Get Checked
1. Pre-approval. The lender looks at your assets, income, and the old home’s status.
2. Contract and appraisal. The new home’s appraisal sets the loan-to-value. Above a lane’s threshold amount, two appraisals are required.
3. Underwriting. Statements are verified, large deposits sourced, and reserves calculated after cash to close.
4. Contract updates. If the old home goes under contract or a contingency clears, send the documents promptly.
5. Closing Disclosure. Under the CFPB’s timing rules, you receive it ahead of closing, with timing that varies by file and lender. Compare its cash to close with your Loan Estimate.
6. Closing. Cash to close leaves your accounts. Reserves are measured on what remains.
Lenders also look at listing dates. Fannie Mae’s rental-income best-practice material tells lenders to check whether a departing home was listed before the note date and whether a sale contingency was removed before closing. Accurate dates protect you.
What If You’re Short?
Short on reserves usually means one of three fixes, and the right one depends on which test is failing.
- Reduce cash to close. A larger down payment helps leverage but drains reserves. Sometimes a smaller down payment leaves more cash behind.
- Move assets into verified form. Liquid, statement-backed funds count. Funds sitting in unverified places do not.
- Wait for the sale. Net proceeds can count once the old home closes and a Closing Disclosure documents them. Confirm the treatment with your lender.
Borrowed funds are the gray zone. A HELOC or bridge loan on the old home adds a liability, and lenders must weigh any related debt. Fannie Mae counts bridge debt in the ratio unless the old home has an executed contract with contingencies cleared. Whether borrowed money can serve as reserves is lender-specific, so ask before you draw.
Gifts and seller credits will not fix a shortfall. Neither will an open-ended promise that the old house will sell.
Where the General Rule Breaks
Several edge cases change the answer:
- Contract exists, contingency not cleared. The old payment still counts under the baseline.
- Sale closes just before your new loan funds. Net proceeds may count as assets with the Closing Disclosure. Confirm against the lender’s rules.
- You keep the old home. A retained home becomes a second property in the reserve math. Fannie Mae’s departing-residence policy requires six months of reserves for the vacated property’s payment when the borrower has less than 12 months of property-management experience. That is the agency baseline, not a jumbo figure. It also says a lease cannot be used to determine rental income for a departing residence. For this reader, the practical point is simple: occupancy decides leverage, and a retained home adds reserve weight.
- Second home. The payment counts and extra reserves apply.
- Refinance versus purchase. Large-deposit explanation rules differ by transaction type, but borrowed funds still get considered.
If the Sale Slips or Falls Through
A contract that collapses changes your file. The old payment goes back into your ratio, and any reserve relief tied to the contract may disappear. Lenders typically recheck the old home’s status near the end of underwriting. If the status changes, tell your loan officer immediately. A surprise discovered at final review is far worse than a problem disclosed early.
Plan for this before you sign. Ask what your file looks like if the old home takes longer than expected. If it only works when everything goes right, it is thin.
Buy First, Sell First, or Contingent Offer?
This is a decision about reserve impact, not just timing.
| Path | Reserve impact | Main tradeoff |
|---|---|---|
| Sell first | Lightest, proceeds become assets | You may need temporary housing |
| Contingent offer | Moderate | Sellers may prefer cleaner offers |
| Buy before selling | Heaviest | Two payments and extra reserves |
Selling first makes the cleanest file. Buying first gives you flexibility at the cost of cash and income strength. A signed contract on the old home sits in the middle and often earns the best balance.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.

Frequently Asked Questions
Can my old home’s equity count as reserves before it sells?
No. Equity is not liquid until the sale closes. Net proceeds may count afterward if documented with a Closing Disclosure. Until then, other verified accounts have to carry the reserve requirement. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Does a listing remove my old payment from my debt ratio?
Not under the baseline. It takes an executed sales contract with the buyer’s financing contingencies cleared. Some jumbo programs may allow a no-contract path, but they usually require heavy extra reserves and vary by lender.
Do I need 12 months of reserves on every jumbo loan?
No. Reserve months vary by lender, program, loan amount, and occupancy. The requirement generally rises with the amount, and there is no universal standard.
Can gift funds or seller credits cover my reserves?
Seller credits cannot be used to meet reserve requirements, because they are interested-party contributions under the Fannie Mae baseline. Gift funds are treated differently from seller credits, and whether they can count toward reserves depends on the transaction and the lender. Otherwise, your own verified assets have to do the work. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Can a HELOC or bridge loan count as reserves?
It depends on the lender. Borrowed funds add a liability, and lenders must consider related debt. Ask before you draw, because the answer changes by program.
