The Quick Read: A jumbo lender counts only vested, delivered shares as income, averages them over your history, and then tests that number against the loan’s fully amortizing payment, not the lower interest-only payment. Unvested grants mostly prove the income will continue. Stock options usually don’t count as income at all. Every jumbo lender writes its own overlays, so the details vary from one program to the next.
Key Terms Defined
RSU (restricted stock unit): A promise of company shares that become yours on a vesting schedule.
Vested: Shares you have earned and now own, with no remaining forfeiture condition.
Interest-only period: A set stretch when scheduled payments cover interest and the balance does not fall.
Qualifying payment: The payment a lender uses to measure your debt ratio, which may differ from what you pay in the early years.
Reserves: Liquid assets, measured in months of the full payment, that remain after closing.
Continuance: Evidence that your income is likely to keep arriving.
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.
Why There Is No Single Rulebook
A loan becomes jumbo when it exceeds the conforming limit, which the FHFA sets each year and raises in high-cost counties. Check your own county’s limit instead of assuming a national figure.
Because agencies don’t buy these loans, each wholesale lender sets its own overlays. Across the jumbo programs Lendmire places files with, the common logic is borrowed from agency guidance, then tightened or loosened lender by lender. So treat what follows as “the usual logic and where it bends,” not one universal rule. Lendmire is a mortgage broker, so it arranges these loans through wholesale lenders. It does not lend.
Step One: Sorting Your Pay Into Buckets
Underwriters generally sort stock compensation into three buckets.
| Type | Usually treated as |
|---|---|
| Vested RSUs or restricted stock | Employment income |
| Stock options, including ESPP | Not income |
| Brokerage holdings | Assets, not income |
Fannie Mae added RSUs and restricted stock as an eligible income source in Selling Guide Announcement SEL-2023-11, and the shares must have vested and been distributed without restrictions. Many jumbo lenders borrow that standard. A sign-on grant that vests over time generally can’t be used either.
Stock options are different. Under Fannie Mae’s employment-related assets rule, options and non-vested restricted stock are ineligible for that income method. Private-company stock is another weak spot, since the agency method expects publicly traded shares.
Step Two: Proving History
Lenders want a record that the shares actually arrived. Expect a request for:
- Your most recent paystub showing year-to-date stock income.
- Two years of W-2s.
- The current vesting schedule, past and future.
- Brokerage or bank statements showing prior deliveries landed.
- Evidence the stock is publicly traded.
An offer letter alone is not enough. Most lenders want a track record with your current employer. The length they require often depends on whether the grant is time-based or performance-based, and it varies by lender. Ask yours up front.
Step Three: Turning Shares Into a Monthly Number
The usual method averages instead of using your best month. A lender takes the vested shares you received over your history, values them at an averaged stock price, and divides by the months in the history. The averaged price is typically a long moving average, not the price on the day you apply.
Here is the effect in plain terms. Say your stock ran well above its average during the past year. Your qualifying figure comes out lower than your recent vests suggest. If the stock has sagged, the reverse can happen. And if your income trends down, many underwriters use the lower recent figure.
Agencies don’t always agree with each other on this math. A jumbo lender can land somewhere else again.
Step Four: Checking That It Will Continue
Underwriters ask whether this income will last. The general expectation is stable income likely to continue for years. Your forward vesting schedule does the work here. Remaining unvested grants show shares still coming.
Here’s where files get misread. A front-loaded grant, where the big award came early and later grants are smaller, can make your share count look like it’s falling. Refresh grants can offset that. A short letter of explanation, with the full grant history attached, helps the underwriter see the real pattern.
What Interest-Only Changes
Interest-only does not give stock pay an easier read. The income calculation is the same. What changes is the payment it gets measured against.
Across the wholesale jumbo lanes, interest-only is one of several structures, alongside fixed and adjustable. The interest-only lanes cap the debt ratio at 43%. The fixed lanes allow up to 50%, and the adjustable lanes sit at 45%. So the structure with the lowest early payment also has the tightest ratio ceiling. Reserves are measured in months of the full payment, and they rise with the loan amount.
There is a legal layer too. Under the CFPB’s Regulation Z ability-to-repay rule, a lender must test an interest-only loan using a payment that repays the loan over the term left after the interest-only period ends. Interest-only loans also fall outside the General QM category, so lenders lean on documentation and conservative income math.
The result is a double test for stock-heavy borrowers:
| Test | What it checks |
|---|---|
| Income calculation | Does averaged stock pay plus salary support the ratio today? |
| Payment after reset | Can you carry the higher amortizing payment later? |
Variable income gets scrutinized twice. If a thin averaged figure is why the numbers fail, the interest-only structure won’t rescue it.
Stock as an Asset: Reserves and Closing Funds
The same shares can’t do everything. Shares you’ve already counted as income are still assets, but lenders are wary of double-counting them without a clear paper trail. Vested holdings can generally count toward funds to close and reserves when their value is verifiable. Under Fannie Mae’s stocks and stock options guidance, vested options are valued by their gain on exercise, and non-vested options aren’t acceptable. Older training materials cite partial percentages for stock balances, and they conflict with current guidance. Your lender’s own rule governs, so confirm it before assuming a haircut or a full value.
Whether you must sell shares to close is lender-specific. Some want proof the funds arrived, others will accept verified value. Don’t sell anything before asking.
The appraisal has nothing to do with stock pay. It sets value and loan-to-value. Wholesale lanes ask for two appraisals above a lane’s threshold amount. Final eligibility is subject to lender guidelines, credit approval, reserves, and property review.
Where the General Rule Breaks
- Stock options: Not income under the agency method. Vested options may help as assets.
- Private-company stock: Often unusable as income, since the method expects public shares.
- Sign-on RSUs: Generally excluded while they’re still vesting.
- Performance-based grants: Typically need a longer history than time-based ones.
- Falling stock price: The averaged figure drifts down, and underwriters may use discretion.
- Government loans: FHA, VA and USDA are generally understood not to offer interest-only structures.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit. The IRS is the place to start for questions about how RSUs are taxed.
When Stock Pay Doesn’t Carry the File
Some borrowers get a thin figure because the history is short or the stock is volatile. Options worth discussing with a broker:
- A different structure, such as fixed, where the ratio ceiling is higher.
- Lower leverage, which can offset a tighter income read. The headline lane reaches 90% on purchases, but not every file needs to push there.
- Waiting for another vesting cycle to lengthen the record.
- Using more cash down so the payment, and the ratio, drop.
Do not stretch to interest-only just to make the numbers look smaller. Remember the CFPB’s warning on interest-only loans: payments rise when the period ends, and you shouldn’t assume you can sell or refinance. If your plan depends on a future stock-price rise or a future refinance, stress-test it first.
A Borrower Checklist
1. Pull your vesting schedule and two years of W-2s.
2. Gather brokerage statements showing past deliveries.
3. Note whether each grant is time-based or performance-based.
4. Write a short explanation of any share-count dips.
5. Ask the lender how it averages the stock price.
6. Ask which payment it uses for your ratio.
Interest-only on a jumbo can make sense for a borrower with strong reserves and a clear income path. It’s a poor fit when approval depends on the lower payment alone. Brokers can usually compare how different lenders read the same stock history, and that difference matters more than most borrowers expect.
Frequently Asked Questions
Can RSUs count as income on a jumbo loan?
Usually, once they have vested and been delivered to you without restrictions. Lenders typically want a documented history and a vesting schedule that supports continuance. Rules differ by lender, so confirm the requirement before applying.
Do lenders use my total grant or my latest vest?
Neither. They generally use vested, delivered shares averaged over your history. Unvested grants mostly help show the income will continue, instead of adding to the monthly figure.
Will a lender qualify me on the interest-only payment?
Not on that payment alone. Ability-to-repay rules point to a payment that repays the loan over the remaining term after the interest-only period. The interest-only lanes also carry a lower ratio ceiling than the fixed lanes.
Are stock options income?
Under the agency method, no. Vested options can sometimes help as assets, valued by their gain on exercise. Whether a given jumbo lender accepts them varies.
What if my company stock drops?
The averaged price softens the effect, but a sustained decline can lower your qualifying income. Underwriters may use judgment, and a clear letter with your grant history can help.
