The Quick Read: It depends on whether you could carry the loan after the rate adjusts, not just during the starting period. An adjustable-rate mortgage (ARM) begins with a lower introductory rate, then resets at regular intervals. Vested stock pay arrives in lumps and moves with the share price, so the question is how you will pay the balance down before the first reset. If you have a clear plan for the cash and a documented vesting history, an ARM can fit. If the plan is “I’ll refinance before it adjusts,” choose fixed.
Key Takeaways
- RSUs (restricted stock units, shares your employer grants that vest over time) count as income only after they vest and are delivered to you.
- Lenders average your vesting history. They do not use your best year.
- Underwriting an ARM looks at a higher payment than the teaser payment.
- Jumbo lenders set their own RSU math, so two lenders can reach different income figures from the same history.
- Your income can be lumpy even when the qualifying average looks smooth.
- A sale or refinance before the reset is a hope, not a plan.
How Do Lenders Count RSU Income on a Jumbo Cash-Out?
Lenders count RSU income when the shares have vested, been delivered to you without restrictions, and show a documented history that is likely to continue. Unvested grants generally do not count. A grant letter promising future shares is not income yet.
A jumbo loan is a mortgage above the county’s conforming limit, the cap on what Fannie Mae and Freddie Mac can buy. A jumbo loan begins one dollar above that limit. The limit changes yearly and varies by county, which is why “jumbo” is not one national number. The FHFA’s published method lets high-cost counties rise above the baseline, up to a cap of 50% above it.
Jumbo loans sit outside the agency framework. Each wholesale lender writes its own rules. Across the wholesale programs Lendmire places files with, the RSU treatment is the single biggest source of variation on equity-comp files. That is why the jumbo cash-out refinance program you choose matters as much as the loan structure. You can see how the program is built on Lendmire’s jumbo cash-out refinance program page.
The agencies are a useful reference point. Fannie Mae’s Selling Guide announcement on RSUs says restricted stock qualifies only if it has vested and been distributed without restrictions. It also calls for your W-2s for the most recent two years. A jumbo lender may be stricter or looser than that, and the file review decides.
What Does the Lender Actually Look At?
A typical file for a stock-paid homeowner includes five items:
- Recent pay stubs showing year-to-date vesting
- W-2s covering the history period
- The RSU grant or vesting schedule
- Brokerage or equity-plan statements showing vested shares
- Employer verification of employment
The history matters because lenders want proof the income repeats. Mortgage-insurer training material from Radian describes a 12-month minimum with the current employer for restricted-stock income. It also describes confirming the income will continue for three years. Sign-on grants that vest over time generally cannot be counted. Treat these as agency-style benchmarks. Your lender’s rule may differ.
The calculation also differs by how you are paid. Share-based RSUs are often valued with an averaged stock price. A MGIC worksheet shows a 200-day moving average for publicly traded stock. A recently public company can complicate that math because there is not enough trading history.
Here is a pattern that shows up constantly. Two lenders look at the same vesting history. One averages over a longer window and lands on a lower monthly figure. The other uses a shorter window and counts more. Same borrower, same shares, different answer. Radian’s own worked example shows Fannie Mae and Freddie Mac producing different monthly figures this way.
How Is a Cash-Out Different From a Purchase for RSU Earners?
On a cash-out, you already own the home and the lender is sizing a new loan against its appraised value. The appraisal sets the value, and that value drives the maximum loan. The same income test applies, but the leverage is different.
| Factor | Purchase | Cash-out refinance |
|---|---|---|
| Leverage | Higher | Lower, with a cash cap on the largest lanes |
| Value source | Price and appraisal | Appraisal |
| Large loans | Two appraisals above a lane’s threshold | Same |
| Right to cancel | No | Yes, on a primary residence |
Across the wholesale jumbo lanes, leverage reaches 90% on the headline lane, though several lanes reach 89.99% combined loan-to-value and the rest stop at 80%. Loans go to $5,000,000 on the largest lanes. Cash-out sits at lower leverage than purchase. These figures are subject to lender guidelines and full file review, and they are not a commitment to lend.
Reserves also scale. Reserves are months of full payments you keep in liquid funds after closing. They rise with the loan amount. A homeowner whose wealth sits in vested shares often has those reserves already. The lender decides how much of the account counts.
Does Qualifying Use the Starting Payment or the Higher One?
Lenders do not qualify you on the starting payment alone. For ARMs, the CFPB’s ability-to-repay guide says the payment is calculated using the introductory rate or the fully indexed rate, whichever is higher. The Federal Register defines the fully indexed rate as the index value at closing plus the margin.
For the borrower, that means the “I’ll be gone before it resets” argument does not shorten the test. Jumbo lenders set their own qualifying rate for the ARM, so there is no single universal rule to quote.
The ratio ceilings reflect this. On the wholesale lanes, the ratio ceiling is 50% on the fixed lanes, 45% on the adjustable lanes, and 43% on the interest-only lanes. The ARM gets a tighter ceiling because the payment is expected to move. Those figures are subject to lender guidelines.
Fixed vs ARM for Stock-Based Pay
For a borrower paid in RSUs, fixed offers certainty and the ARM offers a lower start with a payment that is likely to rise later. The CFPB says many ARMs begin lower than fixed loans, hold for a set period, and then adjust at regular intervals.
| Factor | Fixed | ARM |
|---|---|---|
| Payment predictability | Steady | Changes after the intro period |
| Starting payment | Higher | Usually lower |
| Ratio ceiling on our lanes | 50% | 45% |
| Fit with vest calendar | Easy to plan | Needs a paydown plan |
| Refinance dependence | None | Often assumed, never guaranteed |
The ARM’s weak point for an RSU earner is the refinance-later assumption. A second refinance means qualifying again. If your stock has dropped, your grants have shrunk, or you changed employers, your qualifying average can fall below the pay you are relying on. The plan that worked on paper then needs a different exit.
There is a second mismatch. Your qualifying income is an average, but your household cash flow is not. A big vest in one quarter and a thin one the next can make a payment feel heavier than the ratio suggests. This is a practical point from how the mechanics work, not a published rule.
Stress-Test the ARM Against Your Vest Calendar
Before you pick an ARM, run this self-check. Write down the answers.
1. When do you vest, and how much remains? Count the shares still to come in your current grants.
2. What will the vests do? Decide now whether they go to paying down the balance, building reserves, or spending.
3. Could you carry a higher payment? Assume the rate resets high, not flat. The CFPB’s ARM handbook explains that caps limit how fast the rate rises, but a rate can still rise a long way, and carryover can lift a later payment even if the index has not moved.
4. What if the stock falls? Imagine your vests are worth much less when the reset arrives.
5. What if you leave the employer? Unvested shares may disappear.
The handbook also says your servicer must notify you of the first adjustment at least seven months before the new payment is due. That is useful lead time, but it is notice, not protection.
If you cannot answer question 3 with a yes, the ARM is not your loan.
Who an ARM Suits and Who Should Choose Fixed
| Borrower profile | Likely fit |
|---|---|
| Plans to pay the balance down with scheduled vests before the reset | ARM can fit |
| Long vesting runway, stable employer, strong reserves | ARM can fit |
| Short vesting history or recent grants only | Fixed, or wait |
| Relies on a refinance later to stay afloat | Fixed |
| Income concentrated in one volatile stock | Fixed |
Most of the tension comes down to one trade. The ARM lowers the starting cost in exchange for taking on a future you cannot see. Fixed pays for the certainty up front. Neither is wrong. The mistake is choosing an ARM because the first payment looks comfortable.
Cash-Out vs Selling Shares
You can raise cash two ways: borrow against the home or sell vested shares. Selling may trigger a tax bill. Borrowing adds a monthly payment and a lien. Neither is free.
The useful comparison is the cost of carrying the loan against what selling gives up, plus what the cash is for. A renovation that adds value is a different case than spending. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit. The IRS and a tax professional are the right place for RSU tax questions.
When RSU Income Gets Excluded
These are the usual reasons income does not count:
- The shares have not vested or been delivered.
- The history is shorter than the lender requires, so the minimum controls.
- The income is a sign-on grant that vests over time.
- The company is not publicly traded.
- The trend is falling, so the lender uses a lower figure.
- The lender cannot confirm the income will continue.
Some files hit more than one. When history is short, RSUs may not count at all. The answer then is waiting, not restructuring.
Mistakes Borrowers Make
Assuming the teaser payment is the test. It is not. Qualifying uses the higher rate.
Treating a grant as income on award day. It counts after vesting and delivery.
Assuming every lender counts RSUs the same way. Jumbo lenders set their own rules.
Assuming caps mean the payment cannot jump. Caps slow the climb; they do not stop it.
Skipping the right to cancel. On a cash-out refinance of your primary residence, you generally have three business days to rescind, and the CFPB says the clock does not start until required events have happened. Funds are held until the window ends. That right does not apply to second homes. If you are weighing a second home, occupancy decides the leverage, so say so up front.
Key Terms Defined
RSU: A grant of company shares that you receive as they vest over time.
Vested and delivered: The shares are yours, free of restrictions, and sitting in your account.
Fully indexed rate: The market index at closing plus the lender’s margin; the rate an ARM would carry without the teaser.
Reserves: Months of full housing payments held in liquid funds after closing.
Combined loan-to-value (CLTV): All loans on the home divided by its appraised value.
Conforming limit: The county loan cap above which a loan is jumbo.
Frequently Asked Questions
Does being paid mostly in RSUs change my eligibility?
It changes how the lender builds your income, not whether you can apply. Your salary counts as usual. The stock counts only once vested and delivered, with a documented history. Lenders may average the vests, so a lumpy year gets smoothed or discounted.
Can I use unvested RSUs to qualify?
Generally no. Unvested grants do not count as qualifying income, and some lenders also exclude sign-on grants that vest over time. Your vesting schedule still helps show how much more is coming, which supports the continuance question.
What if my stock price drops after I close on an ARM?
Your approval does not change, but your ability to pay down the loan or refinance may. A falling price means smaller vests, and a later refinance would re-qualify you on lower income. That is why the stress test matters before you choose.
Do all jumbo lenders treat RSUs the same way?
No. Jumbo lenders write their own guidelines, and two lenders can reach different monthly figures from the same history. Comparing programs is worth the effort, and every figure stays subject to lender guidelines and full file review.
Does the ARM change how much I can borrow?
It can. On the wholesale lanes, the ratio ceiling is lower on the adjustable lanes than on the fixed ones. Leverage on a cash-out is also lower than on a purchase. Your appraisal and file decide the final number.
