For Bay Area employees whose compensation includes company stock, “How much home can I afford?” can be surprisingly difficult to answer.
Your salary might represent only part of your total compensation. Restricted stock units, or RSUs, may vest throughout the year. Stock options could hold substantial potential value. An anticipated IPO or tender offer might make a down payment feel within reach.
But a compensation package, a mortgage approval and money available for closing are three different things.
RSUs and stock-sale proceeds can help you buy a home, but their impact depends on the type of equity, whether it is accessible, how your lender evaluates it and what remains after taxes. A future IPO or an unvested award should not be treated as money already available to spend.
For buyers in San Francisco, the Peninsula, Silicon Valley and the wider Bay Area, understanding these distinctions is an important part of setting a realistic budget.
Start with three separate questions
Before calculating a purchase price, separate your finances into three categories:
What income will a lender count?
Salary and other eligible compensation used to assess your ability to repay the mortgage.
What funds can I use to buy?
Documented assets available for the down payment, closing costs and required reserves.
What payment can I comfortably sustain?
Your household budget, including housing expenses, savings goals and potential changes in compensation.
A large stock portfolio may help with a down payment without producing an equally large mortgage approval. Conversely, eligible RSU income may support qualification while the timing of a stock sale still complicates closing.
Do RSUs count as income for a mortgage?
They can, but lenders do not automatically count the full equity value shown in your compensation package.
For example, Fannie Mae’s guidelines require eligible restricted stock income to come from publicly traded stock that has vested and been distributed without restrictions. Restricted-stock sign-on bonuses are excluded from qualifying income under these rules.
For share-based awards, its calculation uses a 200-day moving average stock price and the number of distributed vested shares over the applicable income period. This can produce a different figure from today’s stock price or your employer’s estimate.
Documentation includes pay or employment records, a vesting schedule and statements showing distributions. History and continuation requirements depend on the award type. Time-based awards require at least 12 months of history with the current employer.
The practical question to ask is: “How much of my stock compensation qualifies under this specific mortgage program?”
What about jumbo mortgages?
Jumbo loans exceed the applicable conforming loan limit, and their requirements vary by lender. A rule you read about a conventional conforming loan may not describe the jumbo program you are considering.
When comparing lenders, request the qualifying income calculation alongside the rate and fees. Two loan proposals are difficult to compare if they assume different amounts of eligible compensation.
Can you use RSUs or stock options for a down payment?
Eligible stock assets can help fund a home purchase, but using an asset is different from counting compensation as income.
Fannie Mae permits verified vested stocks to support down payments, closing costs and reserves, subject to its documentation requirements. It also provides rules for valuing vested stock options. Nonvested options are not acceptable funds under those rules.
Whether a lender needs evidence of liquidation depends on the asset, its value relative to the required funds and the applicable program. Do not assume that every buyer must sell everything—or that an account balance alone will satisfy every requirement.
Before making an offer, ask:
Which assets are acceptable for this loan?
What evidence of ownership, sale or transfer is required?
When must the closing funds be available?
How much must remain in reserves after closing?
Keep the deposit timeline in mind, too. Funds needed shortly after an offer is accepted may be required well before the closing date.
How do stock options affect home affordability?
Stock options give you the right to purchase shares at a specified exercise price. Their potential value is not the same as cash you already own.
For example, suppose you hold 10,000 vested stock options with a $10 exercise price and can sell the shares for $40 each. Selling all 10,000 shares would generate $400,000 in gross proceeds. After subtracting the $100,000 cost to exercise the options, you would have $300,000 remaining before taxes and fees. This assumes you can exercise and sell all the shares at that price; private-company restrictions or tender offer limits may prevent that.
Taxes also differ by option type. Exercising incentive stock options, or ISOs, can trigger alternative minimum tax even without a sale. For most nonqualified stock options, the spread between the share value and exercise price is generally compensation income at exercise. A later sale can create an additional gain or loss.
For homebuying purposes, estimate the net cash available after exercise costs, taxes and fees, rather than using the gross value of the underlying shares.
Does an IPO mean you can buy a home immediately?
No. An IPO can create a path to liquidity without making your shares immediately available to sell.
Several separate restrictions may affect the timing.
IPO lockup periods
A lockup agreement limits when certain shareholders can sell after an IPO. The SEC notes that many lockups last 180 days, but the actual terms vary and may include limits on the number of shares released.
Review the company’s prospectus and your applicable agreements rather than assuming that every employee can sell on the same date.
Blackout periods and trading windows
A blackout period is a separate restriction under company trading policies, often associated with earnings announcements. A trading window is a period during which trading may be permitted, subject to the rules that apply to you.
The expiration of an IPO lockup does not automatically mean you are cleared to sell. Confirm your situation with the company’s stock-plan or compliance team.
Vesting and settlement conditions
Your equity plan and award agreement determine when you earn an award and when shares or cash are delivered. A liquidity event can affect different awards differently; it does not automatically make every outstanding grant available.
For a home purchase, work backward from the date funds are needed. Confirm the permitted sale date, expected proceeds and transfer timing before relying on those funds in an offer.
Can a tender offer help you buy before an IPO?
A company-approved tender offer may allow eligible employees and shareholders to sell some private-company shares to the company or another buyer before an IPO.
It can be relevant to a down payment, but an announced offer is not the same as a completed payment. Review the offer documents to establish:
Whether you and your shares are eligible.
How many shares you may sell.
The price and any transaction conditions.
When you should receive payment.
The amount to reserve for taxes and other costs.
Then ask your lender how the proceeds must be documented. Keep the asset and income questions separate: ask whether the lender will treat the proceeds as purchase funds, qualifying income or neither under the proposed program.
How much will taxes reduce your homebuying funds?
The amount shown in your equity account may overstate the amount available for a home.
For typical RSUs, the value delivered is generally taxed as compensation when the award vests and settles. Companies may withhold shares or sell some shares to cover withholding. Subsequent changes in value can create capital gains or losses when you sell. Deferred settlement and other award structures can change the timing.
Before earmarking proceeds for a down payment, have your tax adviser estimate your remaining liability, taking account of withholding already paid.
A useful planning calculation is:
Available purchase funds = net proceeds received − additional tax reserve − cash you intend to retain.
Avoid subtracting the same tax twice if shares were already withheld or sold to cover it.
When most of your compensation is equity, stress-test the payment
Mortgage qualification is one checkpoint. Living comfortably with the payment is another.
If your salary, future awards and existing investments all depend on the same employer, consider what would happen if several changed together.
Compare three household budgets:
Salary only: What housing payment could you carry without stock sales?
Conservative equity income: What changes if future vesting proceeds are materially lower?
Interrupted equity income: What happens if you change jobs or experience a gap between awards?
These are planning scenarios, not predictions. Their purpose is to show how much flexibility your budget contains.
Include the full cost of ownership: mortgage principal and interest, property taxes, insurance, HOA dues where applicable, maintenance and potential assessments. Keep room for your other priorities, including retirement savings, childcare and emergency funds.
For a Bay Area buyer, a larger down payment may reduce the mortgage needed, but it also leaves less cash available for other expenses. Both sides of that decision deserve attention.
What to clarify before making an offer
Before committing to a home purchase that depends on equity compensation, aim to have clear answers to five questions:
What purchase budget has my lender actually evaluated?
Which funds are available for the deposit and closing?
What company restrictions could affect a sale?
How much should remain available for taxes and reserves?
Would the monthly payment still work if my equity compensation declined?
RSUs, options and liquidity events can expand your homebuying possibilities. The strongest starting point is a budget built around documented financing, accessible funds and a payment that fits your life.
