RSU, Stock Options, and Bonus Income: Getting a Luxury Mortgage
RSU
Restricted Stock Units: taxed as ordinary income at vest — appears on W-2, documentable for mortgage
NQSO
Non-Qualified Stock Options: income at exercise = FMV minus exercise price — documentable
ISO
Incentive Stock Options: no regular income at exercise, but Alternative Minimum Tax exposure
Bonus
Annual performance bonus: most lenders require 2-year average; tech-lenders may use current year
Equity compensation is the largest component of total income for most senior technology, finance, and executive professionals — and the most commonly mishandled income type in luxury mortgage underwriting. A senior software engineer with $120,000 base and $280,000 in annual RSU vesting is a $400,000-income buyer. The underwriter who uses only the base salary qualifies them for a $500,000 home when they should be buying a $1.8 million home.

RSU Income: How It Works for Mortgage Qualification
(1) RSUs vest on a schedule (typically 4 years, quarterly). At each vest, shares are delivered and the income appears on the W-2 as ordinary income. (2) Documentation required: 2 years of W-2s showing RSU income (Box 12, Code V for NQSO, or included in wages for RSU). Current vesting schedule showing future grants. Employer letter confirming ongoing employment and continued grants. (3) The vesting cliff issue: an employee who received their first RSU vest 8 months ago has less than 2 years of RSU W-2 history. Most conventional lenders cannot count the income yet. Some portfolio lenders accept the current grant schedule as forward-looking documentation. (4) Grant size trends: if grants are increasing (promotion, refresh grants), the 2-year average understates current income. Discuss this with the lender before application.
Stock Options: The Three Types and Their Tax Treatment
| Type | How Taxed | Mortgage Documentation | Trap to Avoid |
|---|---|---|---|
| RSU | Ordinary income at vest — on W-2 | 2-yr W-2 history + grant schedule | Counting unvested RSUs as income |
| NQSO | Ordinary income at exercise (FMV minus price) | Form 3921, W-2, tax returns | Irregular exercise timing creating income spike |
| ISO | No regular income at exercise; AMT exposure | Only counts if exercised and sold | AMT on spread can create large tax bill |
| ESPP | Ordinary income on discount at purchase | W-2 Box 14, may require documentation | Short holding period creates ordinary income |
NQSOs and RSUs are the most common forms of documentable equity compensation for mortgage purposes. ISOs require careful planning with a CPA before exercise.
Bonus Income: Averaging vs Current-Year Approach
Annual performance bonuses are documentable income for luxury mortgages, with one critical distinction between lenders: (1) Standard approach: 2-year average of bonus from W-2s. If last year’s bonus was $200,000 and the prior year was $80,000: average = $140,000. (2) Tech-experienced lender approach: some lenders use the most recent year’s bonus if it can be documented as reflective of current compensation. On a $200,000 current-year bonus vs $140,000 averaged: the difference in qualifying income is $60,000, which at standard DTI ratios affects qualification by approximately $280,000 in purchase price.
Ryan Brown, Principal Broker & CEO Own Luxury Homes®
“The executive who comes to me with $150,000 base and $350,000 in RSUs and a $2M home in mind gets the specific lender conversation first. Not “you make $150,000, here’s what you qualify for.” The full compensation picture: RSU history, vesting schedule, bonus documentation, and the lender who knows how to use all of it. That conversation changes the purchase by $700,000.”

Frequently Asked Questions
Can I use RSU income to qualify for a luxury mortgage?
Yes, with 2 years of W-2 history showing RSU vesting income and current grant schedule documentation. Portfolio lenders can sometimes use current grant schedules rather than 2-year history for newer employees.
What is the difference between RSUs and ISOs for mortgage purposes?
RSUs create ordinary income on W-2 at vest — fully documentable for mortgage. ISOs create no ordinary income at exercise (but trigger AMT). ISOs are generally not counted as qualifying income unless the shares were sold creating documented income.
Why does the choice of lender matter so much for equity comp mortgages?
A lender using only base salary vs one using full TC including RSU and bonus history can result in a $700K-$1.5M difference in qualifying purchase price on the same income. The specialist connects to tech-income-experienced lenders before any search begins.
