Buying a Home in Silicon Valley With Equity Compensation: A Financial Planning Perspective

When the median house costs around two million dollars, the down payment often comes from company stock. That decision deserves as much thought as the house itself.

Housing is the largest financial decision most Bay Area households will make, and it is also the one most entangled with equity compensation. Vested Registered Stock Units (RSUs), exercised options, and tender offer proceeds are frequently the source of the down payment. Understanding the trade-offs before you start touring open houses can prevent an expensive mistake.

The price of entry

According to a July 2026 market update from Ascend Real Estate, the median single-family home price was approximately $1.92 million in Santa Clara County and $2.15 million in San Mateo County. A 20% down payment on a $2 million home is $400,000, before closing costs, and the resulting $1.6 million mortgage carries a payment that, together with property tax of roughly 1.2% of purchase price and insurance, can easily exceed $12,000 per month.

Funding the down payment with stock

Selling company stock to fund a down payment involves several considerations:

• Taxes on the sale. RSU shares sold shortly after vesting produce little capital gain, since basis equals the value at vest. Older lots with large embedded gains are taxed at federal long-term rates of up to 20%, plus the 3.8% net investment income tax and California's ordinary income rates; Kiplinger lists the 2026 federal thresholds. Budgeting for the tax bill is essential, since the sale proceeds must cover both the down payment and the tax due the following April.

• Timing and blackout windows. If you are subject to trading windows, the sale may need to occur months before you find a house. Many buyers sell in advance and hold cash, accepting the risk that the stock rises after the sale.

• Lender treatment of equity income. Lenders vary in how they count RSU income toward qualifying. Some will include a history of vesting; others will not. Shopping lenders who understand technology compensation can make a difference.

• Diversification. A home purchase funded by employer stock is, in one sense, a diversification event: you are moving from a concentrated equity position into real estate. In another sense, it concentrates you further in the regional economy that drives both your employer's fortunes and local housing prices.

Alternatives to selling

Some buyers consider a securities-based line of credit or a margin loan against a portfolio rather than selling. This preserves the position and defers the tax but introduces leverage and the risk of a margin call if the stock falls. Given the volatility of individual technology stocks, this approach carries meaningful risk and is generally suited only to those with diversified portfolios well in excess of the loan amount.

The rent-versus-buy question

Silicon Valley's price-to-rent ratio is among the highest in the country, which means renting is often cheaper on a monthly basis than owning an equivalent home. The case for buying rests on long holding periods, appreciation, the mortgage interest deduction (limited to $750,000 of acquisition debt for most buyers), the higher state and local taxes (SALT) cap discussed in a separate article, and the stability of a fixed housing cost under Proposition 13. The case for renting rests on flexibility, lower carrying costs, and the ability to keep capital invested in diversified assets. A tech professional who might change employers or cities within five years should weigh transaction costs, which can approach 6% to 8% of the price on a round trip.

Proposition 13 and the long view

One underappreciated feature of California homeownership is that property taxes are based on purchase price and can rise only about 2% per year thereafter. A homeowner who stays for twenty years will pay taxes on an assessed value far below market. For those 55 and older who later downsize, Proposition 19 allows transfer of that assessed value to a replacement home anywhere in the state, per the California State Board of Equalization.

Protecting the plan

A home purchase should not consume the entire financial cushion. Reasonable guidelines include retaining an emergency reserve of six to twelve months of expenses after closing, continuing retirement contributions, and avoiding a mortgage that depends on future equity vesting to service. Equity compensation can disappear with a job change; the mortgage does not.
