Quick read
- A liquidity event changes what you can buy and how fast you can close, but only if your financing paperwork is ready before the wire lands.
- Proof of funds means liquid. Lenders and listing agents treat vested, sellable shares very differently from unvested RSUs or unexercised options.
- You can often match the speed of all-cash buyers with a securities-backed line of credit or a fully underwritten preapproval.
- Lockups, blackout windows, and 10b5-1 plans set your real timeline. Plan the home search around the calendar, not the headline.
- Stock sales and home sales both carry significant tax consequences in California. Talk to a CPA before you sell anything.
Buying a House After an IPO: Why the Liquidity Moment Matters
Every year on the Peninsula, a wave of households goes from paper wealth to spendable wealth in a single quarter. An IPO prices, a tender offer closes, a secondary sale clears, or a large block of RSUs vests. The question that follows is almost always the same: can we finally buy the house, and how quickly should we move?
The honest answer is that the liquidity event is the middle of the process, not the start. In May 2026, the median single-family home sold for 4,200,000 dollars in Palo Alto, 4,564,000 dollars in Los Altos, and 3,951,500 dollars in Menlo Park, with Atherton at 11,075,000 dollars, and homes across these cities closing at or above asking price on average (SAMCAR and SCCAOR, May 2026). At those numbers, sellers and their agents look hard at where your money is, how fast it can move, and whether your offer will survive underwriting.
Buyers who start preparing three to six months before the money arrives consistently do better than those who start the weekend after. Preparation means knowing which shares are vested and sellable, what your lender will count, what your trading windows allow, and which neighborhoods fit your life. Lisa builds this runway with clients well before a lockup expires, so the offer is ready when the right home comes up.
Turning RSUs and Tech Equity Into Proof of Funds
Proof of funds is where most equity-rich buyers get tripped up. A listing agent reviewing offers on a competitive Palo Alto property wants to see money that can wire on schedule: settled cash, or assets that can become cash within days.
Here is how the main forms of tech equity are usually treated:
- Vested public-company shares in a brokerage account: generally accepted as proof of funds, often with a discount applied for price movement, as long as you are free to sell.
- Unvested RSUs: not proof of funds. They may count toward mortgage qualifying income if you have a vesting history (commonly two years) and the lender can document that vesting continues.
- Unexercised stock options: not proof of funds until exercised and sold, and exercising has its own tax consequences worth reviewing with a CPA first.
- Private-company shares: typically not usable unless a tender offer or secondary sale is signed and scheduled to fund before closing.
Two practical notes. First, lenders look at deposit seasoning, so keep trade confirmations and wire records organized. Second, ask for a fully underwritten preapproval rather than a basic prequalification letter. Listing agents know the difference, and the stronger letter changes how your offer reads.
Selling Stock to Buy a House on the Peninsula: Competing With All-Cash Offers
In San Mateo County and Santa Clara County, a meaningful share of offers on homes above 3 million dollars are all cash, and many of the rest are written without financing or appraisal contingencies. If your wealth is concentrated in company stock, you have three broad ways to compete.
First, sell shares ahead of the search and hold cash. This is the simplest path and produces the cleanest offer, at the cost of triggering capital gains now and stepping out of the stock. Second, borrow against the portfolio with a securities-backed line of credit or pledged-asset loan, usually at 50 to 70 percent of portfolio value, write a cash offer without selling, and decide later whether to sell shares or refinance into a mortgage. The risk is a margin call if the stock falls, so size the line conservatively. Third, use a fast conventional loan from a lender who works with equity compensation and can close in 14 to 21 days with underwriting done up front.
Structure matters as much as money. A 10 to 14 day close, a large initial deposit, and clean contingencies often beat a slightly higher offer with a 30 day escrow. Lisa coordinates directly with clients' wealth managers and lenders so the offer terms match what the money can actually do. The mechanics of each financing route are covered in more depth in the full equity-to-home playbook.
How to Buy a Home With Stock Options and RSUs: Lockups, Vesting, and 10b5-1 Timing
If your shares come from a recent IPO, the calendar is not fully yours. Standard lockup agreements restrict sales for 90 to 180 days after the offering. After the lockup, employees with material nonpublic information face quarterly blackout windows around earnings, and executives and other insiders often sell only through 10b5-1 plans, which schedule sales in advance and carry mandatory cooling-off periods before the first trade.
This matters for a home purchase in a concrete way: never write an offer that depends on money you are not yet legally allowed to move. An escrow that closes three days before your trading window opens is a failed escrow, and a forfeited deposit on a 4 million dollar purchase is real money.
The better approach is to work backward from the calendar:
- Map your lockup expiration, vesting dates, and open trading windows for the next two quarters.
- If you use a 10b5-1 plan, build home-purchase liquidity into the plan's schedule rather than hoping a window lines up.
- Pre-position cash for the earnest money deposit, typically 3 percent of the purchase price, so it never depends on a future sale.
- If a window might close mid-escrow, consider a securities-backed line as a bridge so the closing date does not hinge on a trade.
Selling Your Current Home and Selling Stock in the Same Year: The Tax Picture
Many liquidity-event buyers are also sellers, trading a townhouse in San Mateo or a starter home in Mountain View for more space. Stacking a stock sale and a home sale in the same tax year deserves real planning. California taxes capital gains as ordinary income on top of the federal rate, and large gains can also trigger the 3.8 percent net investment income tax.
A few anchors to discuss with your CPA:
- The primary residence exclusion under Section 121 shelters up to 250,000 dollars of gain for a single filer and 500,000 dollars for a married couple, if you have owned and lived in the home for two of the last five years. On long-held Peninsula homes, gains often exceed the exclusion, so model the tax on the remainder.
- A 1031 exchange can defer gains on investment property, not your own residence, and it runs on strict deadlines: 45 days to identify a replacement property and 180 days to close.
- The order of operations matters. Selling stock in December versus January, or spreading sales across two tax years, can change the total bill meaningfully.
- Withholding on RSU vests is often below your actual marginal rate, so set aside the gap before committing it to a down payment.
None of this is tax advice. What Lisa does is sequence the real estate side, listing timeline, purchase timeline, and rent-back terms, so the plan your CPA designs survives contact with a live transaction.
Choosing the Right Peninsula Neighborhood and School Fit
A liquidity event widens the map, and that is its own problem. The practical filter is daily life: commute, schools, and what you want from a lot.
Menlo Park and Palo Alto put you close to Sand Hill Road, Stanford, and the mid-Peninsula employers, with walkable downtowns and Caltrain access. Los Altos trades some of that walkability for larger lots and a quieter pace, with quick reach to the 280 corridor and the South Bay campuses. Atherton is the move when privacy and acreage lead the list. Further north, San Mateo and Burlingame offer a softer entry point with an easier run to San Francisco.
Schools deserve specific attention rather than a quick ratings glance. District boundaries on the Peninsula do not follow city lines. Parts of Menlo Park feed Las Lomitas, others feed Menlo Park City School District, and the difference shows up in pricing block by block. Palo Alto Unified serves nearly all of Palo Alto, part of why the city's median holds. If private school is the plan, proximity and traffic patterns matter more than district maps.
Finally, buy for a longer hold than you think. Transaction costs at this price point are substantial; treat the post-liquidity purchase as a seven to ten year decision. A home that fits the next decade beats a trophy that fits the next dinner party.
Frequently Asked Questions
Can I use unvested RSUs to qualify for a mortgage?
Not as assets, but often as income. Lenders will not count unvested RSUs toward your down payment or reserves because you cannot sell them. Many lenders will include RSU vesting in your qualifying income if you can show a consistent vesting history, usually around two years, and documentation that vesting continues at a similar level. The lender typically applies a discounted share price to be conservative. If RSUs are a large part of your compensation, choose a lender that underwrites equity compensation regularly.
How do I show proof of funds if most of my money is in company stock?
Provide recent brokerage statements showing vested, freely tradable shares, alongside any cash accounts. Listing agents generally accept liquid securities as proof of funds, though they may mentally discount the value for volatility. If your offer depends on selling those shares, be ready to explain the timeline: which trading window you will use, how many days settlement takes, and when the wire arrives. For private-company stock, you will need signed documentation of a tender offer or secondary sale that funds before closing. Organized paperwork reads as competence, and sellers reward it.
Do I have to sell my stock before making an offer?
No. A securities-backed line of credit or pledged-asset loan lets you borrow against your portfolio, write a cash-equivalent offer, and close without selling a share. You can then sell stock later on your own schedule, or refinance into a conventional mortgage. The tradeoffs are interest costs and margin-call risk if the stock drops, so most advisors recommend borrowing well below the maximum available. Selling in advance is simpler and removes market risk from the purchase. The right answer depends on your concentration, tax picture, and risk tolerance, which is a conversation for your advisor and CPA.
How long after an IPO should I wait to buy a home?
You can start the search immediately; you just cannot always fund a purchase immediately. Most lockups run 90 to 180 days, and trading windows after that depend on earnings calendars. Use the lockup period to get fully underwritten with a lender, map your sale windows, and tour neighborhoods seriously. One caution: when a large local company's lockup expires, multiple colleagues often enter the market at once. Buyers who prepared during the lockup and can move in the first weeks face less of that internal competition than those who start after the shares settle.
Will I owe taxes when I sell stock to buy a house?
Almost certainly, and the amount depends on holding period and income. Federal long-term capital gains rates apply to shares held more than a year, with the 3.8 percent net investment income tax on top for most buyers at this level. California taxes capital gains as ordinary income, which is often the largest single piece. RSUs are taxed as ordinary income at vesting, and the default withholding frequently undershoots the real liability. Before selling a large block to fund a down payment, have a CPA model the after-tax proceeds so the number you shop with is the number you actually have.
What this means for you
A liquidity event does not buy a Peninsula home; preparation does. The buyers who win in Menlo Park, Palo Alto, and Los Altos are the ones whose financing, trading calendar, and target neighborhoods were settled before the money moved. If a lockup expiration or vesting date is on your horizon, start with the full equity-to-home playbook, then book a discreet consult with Lisa to put a timeline against it.
