Using RSUs and Stock for a Down Payment in Seattle

An RSU down payment Seattle buyer typically builds by selling vested restricted stock, and an underwriter cares less about the account balance than the paper trail behind it. Unvested shares generally cannot be used as assets at all. What counts is the sale confirmation, the transfer into a bank account, and enough time for the deposit to season. Every figure here is illustrative, subject to qualification.

I write a different guide for RSU income, which is about qualifying on ongoing pay. This one is about the separate question buyers near South Lake Union ask constantly: can I actually use my stock to cover the down payment and closing costs, and if so, how do I do that without slowing down my file. The two questions overlap, but the rules and the paperwork are not the same.

A note up front: this guide covers how a lender sources and documents stock proceeds as an asset. Whether to sell, when to sell, and the tax consequences of a sale are questions for your financial adviser and CPA, not your loan officer.

What Counts as an RSU Down Payment Seattle Lenders Will Accept?

An RSU down payment Seattle lenders will accept is built from vested shares that you actually hold, whether still in the brokerage account or already sold to cash. Unvested shares sitting on your vesting schedule are not usable as assets, because they are not yours yet and their future value is not assured. This is a different test than the income side of RSU qualifying, where a history and continuance of vesting can support ongoing income. For a down payment, the underwriter wants to see money you already have, not money you expect to have.

Two paths get you from vested stock to usable cash. You can leave shares in the brokerage account and document them as a liquid asset, which some loan programs allow toward reserves without a sale. Or you can sell the shares and move the proceeds to a bank account, which is the more common route when the funds are actually needed at closing rather than held as a reserve. Which path fits depends on how much of your down payment the stock needs to cover and how close you are to closing.

This distinction matters more in Seattle than in most markets, because the central-city buyer pool leans so heavily on equity compensation. A South Lake Union condo commonly runs 725,000 to 825,000 dollars, and a meaningful share of buyers there are funding a large piece of the down payment from a brokerage account rather than a traditional savings account.

Sourcing and Seasoning: The Paper Trail an Underwriter Wants

Sourcing and seasoning are the two concepts that govern every large deposit in a mortgage file, and a stock sale triggers both. Sourcing means proving where the money came from. Seasoning means proving it has sat in your account long enough to be considered stable rather than borrowed or gifted at the last minute.

• The sale confirmation. Your brokerage statement or trade confirmation showing the shares sold, the sale date, and the net proceeds is the anchor document. It should tie the sale directly to shares you can show as vested.
• The transfer record. A bank statement showing the deposit landing in your account, matched in amount and date to the brokerage withdrawal, closes the loop for the underwriter.
• Two months of statements, generally. Most conventional files want the most recent two months of asset statements. A large, unexplained deposit inside that window gets flagged and needs a paper trail exactly like this to clear.
• A written explanation letter, only if asked. If the sale and transfer are clearly documented and dated consistently, most underwriters do not need anything beyond the statements themselves.

The practical lesson is to sell earlier rather than later when you can. A sale that happened four months before application, with the proceeds already sitting in your bank account across two full statement cycles, generates almost no underwriter questions. A sale that happens the week before closing generates several.

Vesting Schedules and Blackout Windows: Why Timing Drives Your Closing Date

A stock-funded down payment is one of the few funding sources where the calendar genuinely constrains the transaction, and two timing issues come up often for Seattle tech buyers.

• Vesting date versus contract date. If a meaningful share of your down payment depends on shares that vest after you are already under contract, the closing date needs to sit safely after the vesting date, with time left for the sale, transfer, and seasoning. Writing an offer that assumes a vest that has not happened yet is a common and avoidable mistake.
• Blackout and trading-plan windows. Employees at public companies, and some pre-IPO companies with internal trading policies, are often restricted to specific trading windows tied to earnings releases or set by a 10b5-1 plan. A sale that would otherwise be routine can simply be unavailable for weeks at a time.
• RSU withholding at vest. Most employers sell a portion of vesting shares automatically to cover tax withholding, so the shares you actually receive are already net of that. Plan the down payment math on the net share count, not the gross grant.

The fix for all three is the same: bring your vesting schedule and your employer's trading-window policy to the pre-approval conversation before you write an offer, not after. A local lender can build a closing timeline around the calendar you actually have instead of the one a generic pre-approval letter assumes.

Leaving Shares Unsold: Using a Brokerage Account for Reserves

Not every buyer needs to liquidate stock. Some loan programs allow a percentage of a vested, liquid brokerage account balance to count toward reserves, the months of payments a lender wants to see left over after closing, without selling anything. This is a narrower use than a down payment, since reserves are about proving staying power after the loan closes rather than funding the transaction itself.

Where this comes up in Seattle files: a buyer with a strong vested position who wants to keep the stock invested rather than realize a sale, particularly one facing a large unrealized gain and a tax hit for selling in the wrong year. Documentation still applies, showing the account is liquid, vested, and currently valued, and the lender will typically apply a discount to the market value before counting it. This is a conversation to have early, since not every loan program treats brokerage reserves the same way.

Gift Funds, ESPP Proceeds, and Other Adjacent Sources

A stock-funded down payment rarely stands entirely alone. A few adjacent sources show up often in the same file and are worth understanding together.

• Employee stock purchase plan (ESPP) proceeds. Shares purchased through payroll deduction at a discount and later sold follow the same sourcing and seasoning rules as RSU sales: sale confirmation, matched deposit, and the standard statement window.
• 401(k) loans against vested balances. A loan against your own retirement account is a separate funding path with its own documentation and its own effect on your debt-to-income ratio, your monthly debts divided by your monthly income, since the loan payment counts as a liability.
• Gift funds layered with a stock sale. A parental gift covering part of the down payment alongside stock proceeds is common among first-time South Lake Union condo buyers. Gift funds need their own signed gift letter and a documented transfer, separate from the stock paper trail.

Each source has its own document list, and combining two or three at once is where files get complicated. Laying them out with your loan officer before you make an offer, rather than after, is what keeps a multi-source down payment from becoming a closing delay.

The South Lake Union Buyer Funding a Down Payment From Stock

South Lake Union is the center of gravity for this exact scenario. The corridor is anchored by Amazon's headquarters campus and a dense biotech cluster including Fred Hutch, UW Medicine, and the Allen Institute, and its housing stock is overwhelmingly mid- and high-rise condominium, the densest concentration in Julie's territory outside downtown proper.

A few patterns show up repeatedly in these files:

• A single large vesting event funds most of the down payment. A buyer waits for an annual vest, sells promptly, and times the offer to land after the proceeds have seasoned.
• HOA dues change how much stock you actually need to sell. South Lake Union HOA dues commonly run several hundred to over a thousand dollars a month and factor into debt-to-income, which can shift how much cash a buyer needs to bring versus finance.
• Condo warrantability affects the whole plan. The building's warrantability status can matter as much as the funding source, since a non-warrantable building changes the loan program and often the down payment percentage required.

My office sits at 2701 Eastlake Ave E, about a ten-minute walk from the South Lake Union employment core, and I see this funding pattern constantly. The value of working with a local lender on an RSU down payment Seattle file is not a faster form. It is building the sale, the transfer, and the closing date around your actual vesting calendar instead of a generic 30-day timeline that assumes cash sitting in a checking account already.

Which Documents Does an RSU Down Payment Seattle Lender Ask For?

Because buyers ask how the different funding sources compare, it helps to see them side by side. The table below is a program-level summary of how each is generally treated.

All entries above are illustrative and program-level, dated to September 2026. Your actual eligibility and documentation requirement are confirmed against a full loan estimate, subject to qualification and underwriting approval.

Where This Fits in the Rest of This Series

A stock-funded purchase rarely lives on one page. A few related reads round out the picture for a South Lake Union or Eastlake tech buyer.

• The income side. The RSU income mortgage guide for Seattle covers qualifying on ongoing RSU and bonus pay, which is a separate test from funding the down payment covered here.
• Gift funds in more depth. The gift funds mortgage guide for Seattle covers the letter and transfer requirements when a stock sale is paired with family help.
• The jumbo layer. The Seattle jumbo mortgages guide covers what changes when a stock-funded purchase crosses the conforming limit, which happens routinely in South Lake Union towers.
• The neighborhood foundation. The South Lake Union home loans hub gives the full area picture, and the Eastlake, Seattle home loans hub covers the corridor a short walk away.

I keep these cross-linked because funding the transaction and qualifying for it are two different underwriting questions, and most stock-heavy buyers need both answered before they write an offer.
