The Quick Read: A jumbo lender multiplies a set number of months by your full monthly housing payment, subtracts the cash you need to close, and checks whether the verified assets left over cover the rest. Only vested, deposited shares count toward that total. Unvested restricted stock units do not, no matter how large the grant looks on your compensation statement. The month count and the way shares are valued vary by lender and by loan size.
Key Takeaways
- Reserves are cash and near-cash assets you must still hold after closing. They are not a monthly cost.
- The target is months of payment times the full payment: principal, interest, taxes, insurance and association dues.
- Funds to close come out of your assets first. Reserves are what remains.
- Vested shares sitting in a brokerage account, with statements, can count. Unvested grants cannot.
- The same dollar cannot be your down payment and your reserves.
Why Do Jumbo Loans Carry Reserves at All?
Because nobody else is standing behind the loan. A jumbo loan starts one dollar above the county’s conforming limit, so the big mortgage buyers do not purchase it. The lender or its investor sets its own credit policy, and reserves are part of that policy.
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.
No federal formula sets the number. The CFPB’s consumer guidance on conventional loans says jumbo rules vary by lender and usually call for strong credit and a sizable down payment. That matches what Lendmire sees every week.
Across the wholesale jumbo loan programs Lendmire places files with, the envelope looks like this. The headline lane starts at a 660 decision score. Leverage reaches 90% on the top lanes, and several lanes stop at 80%. Loans run to $5,000,000 on the largest lanes. The fixed lanes allow a 50% ratio ceiling. Reserves and appraisal requirements grow with the loan amount. Every figure is subject to lender guidelines and full file review.
Reserves scale because a bigger loan means a bigger payment to cover if income stops. The cushion grows with the exposure.
How Is the Reserve Target Calculated?
The target is required months multiplied by your full monthly housing payment. The payment includes principal, interest, property taxes, homeowners insurance and any association dues. Lenders call this PITI plus dues. People often forget the last three pieces, and they add up in expensive areas.
Here is the sequence a lender follows:
1. Find the lane and loan amount. The amount decides the reserve tier. Larger amounts mean more months.
2. Compute the full payment. Use every component, not just principal and interest.
3. Multiply by the required months. That gives the reserve target.
4. Set aside funds to close. The down payment and closing costs come out of verified assets first.
5. Value what is left. Cash counts at face value. Other assets may be counted at less than market value.
6. Compare the result to the target. A shortfall is a file problem. Fixing it means more verified assets, not a different price.
Two things push the months up or down. Occupancy matters, since a primary home, a second home and a rental can carry different leverage and different expectations. Loan size matters even more.
What Counts Toward Reserves, and What Doesn’t?
Liquid, verifiable assets count. Locked, unvested or hard-to-value assets do not, or count for less. The Fannie Mae asset guidance says vested stocks, bonds and mutual funds are acceptable for reserves when their value can be verified. Jumbo is a separate channel, but lenders often borrow that logic and add their own overlays.
| Asset | Usually counts? | What the underwriter wants | Tech-employee note |
|---|---|---|---|
| Checking and savings | Yes, at face | Recent statements | Cleanest source |
| Vested RSU shares in a brokerage account | Often, possibly discounted | Statements showing the shares | Must be deposited and visible |
| Other brokerage holdings | Often, possibly discounted | Recent statements | Single-stock risk draws scrutiny |
| Retirement accounts | Sometimes, at vested value | Vested balance statement | Lender may discount further |
| Unvested RSUs | No | Not applicable | Forfeited if you leave |
| Pre-IPO or private equity | Generally no | Not applicable | Hard to value or sell |
| Gifts toward reserves | Generally no | Not applicable | Interested-party funds are restricted |
Treat the “possibly discounted” cells as the part that varies. Some lenders count vested shares at full market value. Others count a portion, because share prices move. Ask which treatment applies before you plan around the number.
How Do Vested RSUs Count, and Why Don’t Unvested Ones?
Vested shares are yours. Unvested shares are a promise. A lender can only count what you can sell or withdraw today without losing it.
When RSUs vest, the shares are valued at market price and treated as income. Part of the shares is typically withheld to cover taxes. You receive the net shares, which are fewer than the gross number on your grant notice. A lender counts what actually landed in your account, not the headline grant.
Documentation is where tech files stall. Expect to provide recent brokerage statements showing the shares, and the vesting schedule. Some lenders also want a history of prior distributions. A grant that has not vested stays on the sidelines. So does stock from a sign-on package that vests over time.
If you want to see how a different loan type treats the same assets, Lendmire’s piece How a Jumbo Cash-Out Lender Counts RSUs and Deferred Comp as Reserves covers that angle.
RSU Income Is a Separate Test
Reserves and income are two different questions, and mixing them up causes confusion. Income asks whether you can make the payment. Reserves ask what you have in the bank if something goes wrong.
For income, the Fannie Mae Selling Guide’s RSU section is the public benchmark. It requires that restricted stock has vested and been distributed to the borrower without restrictions. It excludes sign-on awards paid as restricted stock that vest over time. It also asks for documents: a verification of employment or paystubs with W-2s, evidence the stock is publicly traded, the vesting schedule, and brokerage statements showing past distributions. For share-based income, it uses a 200-day moving average of the stock price.
Jumbo lenders set their own rules, so treat that as a reference point. A big vesting award does not create a bigger reserve requirement. It may help your income. It does not change the months you owe. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Worked Example: A Tech Employee With a Mixed Picture
Picture a buyer at a public software company. She is buying a primary home with a down payment of 20% of the price, well within a lane that reaches 90% leverage. She has savings, vested shares in a brokerage account, a retirement account, and a large unvested grant. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Walk the logic without dollars:
| Step | What happens | Result |
|---|---|---|
| 1. Start with all assets | Savings, vested shares, retirement, unvested grant | Everything on paper |
| 2. Remove unvested grant | Does not count for reserves | Pool shrinks |
| 3. Pay funds to close | Down payment and closing costs come out first | Pool shrinks again |
| 4. Value what remains | Savings at face, shares and retirement possibly discounted | Usable reserve value |
| 5. Compare to target | Months times full payment | Pass, or a shortfall |
Her paper wealth looks large, but the unvested grant drops out first. The down payment takes the next bite. What is left must cover the target after any discounts.
Suppose she comes up short. She has options. She could sell some vested shares into cash well before application. She could lower the leverage she requests, which reduces the loan amount and the reserve tier. She could pick a lane with a smaller reserve ask. Each choice trades something, and the right one depends on her taxes and her goals.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Can the Same Shares Be Income, Down Payment and Reserves?
No. One dollar does one job. If you sell vested shares to fund the down payment, those proceeds are spent. They cannot also appear in the reserve column.
| Use of the same vested shares | Counts for | Effect on the others |
|---|---|---|
| Sold for down payment | Funds to close | Gone from reserves |
| Held in brokerage | Reserves, possibly discounted | Not available at closing |
| Averaged as RSU income | Qualifying income | Does not add to assets |
The last row surprises people. Vested shares can raise your income and also sit as an asset, but a given share is only spent once. The proceeds from selling it count once.
Large deposits from share sales also need a paper trail. Expect to show the sale on the brokerage statement and the matching deposit in your bank account. Clean records save you a request later.
Where the General Rule Breaks
Several situations change the picture. Each one is a place where a well-meaning plan goes sideways.
- Private-company equity. If the stock is not publicly traded, it generally cannot count for reserves or income.
- Recent IPO. A short trading history can break the averaging method used for share income.
- Short vesting history. Time-based awards usually need a track record before income counts. Reserves from vested shares do not need a history, but the shares must be in your account.
- Job change. Unvested shares are forfeited when you leave. If you switch employers during the process, the file changes.
- Concentrated single stock. When most of your wealth sits in one company’s shares, some lenders discount it harder.
- County crossover. A loan can be jumbo in one county and conforming in another. The FHFA conforming loan limit announcement sets a baseline and a higher ceiling for high-cost areas, so check your county before assuming which side you are on.
- Two appraisals. Above a lane’s threshold amount, you need two appraisals, which affects the file but not your reserves.
How Should You Time Vests and Sales Around Closing?
Plan so your assets are settled and visible before the lender reviews statements. If a vest date falls before application, the shares can be in your account and on a statement. If it falls mid-process, you may need to send updated documents.
Selling shares carries tax consequences, and a market drop between application and closing could shrink what you counted on. Many buyers decide to sell enough to cover closing and a cushion of reserves, then hold the rest. That is a judgment call, and a tax professional should weigh in. The point for the file is simple: whatever you rely on should be sitting in your account when the underwriter looks.
What Documents Should You Gather?
Pull these together before you apply:
- Two or more months of statements for checking, savings and brokerage accounts
- The latest retirement account statement showing the vested balance
- The vesting schedule from your employer’s equity portal
- Recent paystubs and W-2s showing RSU income
- A record of any share sales and the matching deposits
Common Mistakes
- Counting the grant value instead of the vested, deposited shares.
- Forgetting taxes, insurance and association dues in the payment.
- Using the same dollars for closing and for reserves.
- Selling shares right before application without documenting the deposit.
- Assuming one lender’s treatment of RSUs applies everywhere.

Frequently Asked Questions
Do unvested RSUs count toward jumbo reserves?
No. Unvested stock is not an acceptable reserve source under the public benchmark, and jumbo lenders generally follow that logic. Only vested shares in your account, backed by statements, can be counted.
Does the lender count my shares at full value?
It depends on the lender. Some count vested shares at market value, while others count a portion because prices move. Ask before you plan around a specific number.
How many months of reserves will I need?
It depends on the lane and the loan amount. Reserves are measured in months of your full payment and rise as the amount rises. A broker can tell you the tier for your file once the loan size is known.
Can I use gift money for reserves?
Generally not. Funds from interested parties are restricted from satisfying reserve requirements under the public benchmark. Your own verified assets are what count.
Does selling shares hurt my application?
Not by itself. What matters is a clear paper trail from the sale to your bank account, and enough left over to meet the target after closing. Talk to a tax professional about the tax side.
