"Can I Use Vested Stock Options for a Down Payment and Reserves on a Mortgage?"

Your equity portal has a grant on it from four years ago. Part of it has vested, part of it has not, and the stock trades a long way above the price printed on the grant. You have never exercised a single option, and the home you want to buy closes in sixty days.

Vested stock options can pay for your down payment, your closing costs and your reserves. The lender values them by the gain you would realize from exercising the options and selling the stock, documented from a statement that lists the number of options and the option price, against the current stock price. Options that have not vested do not count and stay off the loan application.

I'm Jeff Moran, a mortgage broker in Bluffton, South Carolina, originating since 1996, NMLS #483943, through C2 Financial Corporation, licensed in fifteen states. Vested stock options count toward your purchase, and the rules for them are written in the agency guides and in my own lenders' guidelines.

How does a lender value vested stock options?

The lender values them by the gain you would get from exercising them, which is a smaller number than the share price times the option count.

Fannie Mae's Selling Guide section on stocks, stock options, bonds and mutual funds, B3-4.3-01, covers it in one row of a table: "The value of vested stock options can be documented by a statement that lists the number of options and the option price, and using the current stock price to determine the gain that would be realized from exercise of an option and the sale of the optioned stock." The same row carries a note: "Non-vested stock options are not an acceptable source of funds for the down payment, closing costs, or reserves and should not be entered on the loan application."

An option gives you the right to buy a share of your company's stock at a set price, called the option price or the strike price. Exercising the option means buying the share at that price. The gain is the difference between what the stock trades for today and what the option lets you pay for it, multiplied by the number of options that have vested. That difference is the asset on your file. The option price is what you pay to exercise, so the lender counts only the gain above it.

Freddie Mac reaches the same place. Freddie Mac's guide section 5501.3 lists vested stock options among the securities you can use, next to stocks, bonds and mutual funds. Freddie Mac asks for one month of account statements when its automated underwriting system allows its lighter documentation, and two months on every other file. The same table says stock "with limitations on its accessibility (e.g., restricted stock that has not vested and been distributed to the recipient) is not eligible."

The statement that matters is the one from your equity plan administrator or the brokerage that holds the grant. It shows the grant date, the number of options, the option price, how many have vested and how many have not. Please provide all pages of it when you're ready, even if the last page is intentionally left blank, along with the most recent one or two monthly statements, depending on your loan program, for the brokerage account the proceeds would land in.

Options you exercise year after year can sometimes count as income as well. That is a separate test, covered in the post on using RSUs and stock compensation to qualify, and one of my lenders' income chapters asks for a two-year history of vesting and exercise with a three-year expectation of continuance.

Do I have to exercise my options before closing?

The money has to reach the closing, so an exercise and sale happens at some point. The guide decides whether the file has to document that sale before the loan is approved.

Fannie Mae's B3-4.3-01 says that when the asset is used for the down payment or closing costs, "if the value of the asset (as determined above) is at least 20% more than the amount of funds needed for the down payment and closing costs, no documentation of the [client's] actual receipt of funds realized from the sale or liquidation is required." Below that cushion, the file documents the sale and the money arriving. The post on selling stock for a down payment walks through that 20 percent test with the arithmetic. The test runs the same way on an option grant, because the value "as determined above" for an option is the gain on exercise.

Luxury Mortgage Corp. is one of the wholesale lenders I work with. Its Simple Access product suite is a non-agency line, meaning those loans are not sold to Fannie Mae or Freddie Mac and the lender writes its own rules. Its current underwriting guidelines (version 9.2, revised July 31, 2026) cover this under section 6.3, Asset Eligibility, in a paragraph headed "Stock Options - if Exercisable." It opens: "Vested Stock Options are an acceptable source of funds for down payment and closing costs if they are immediately available to the Applicant." The applicant is you. "Immediately available" is the condition that lender's guidelines set, so on a file with that lender the question is whether your plan lets you exercise now. Your plan administrator can answer that, along with when the cash from an exercise settles, and I would rather have both answers before the offer than after it.

The taxes that come due when you exercise

Taxes may come due when you exercise, when you sell, or both, and the amount depends on your own situation. That is a conversation for your tax professional before the exercise, and nothing here is tax advice.

The lender does read the tax question from its own side. Luxury Mortgage's section 6.3 continues: "If the brokerage firm or fiduciary that negotiated the execution of the Stock Options did not deduct income taxes from the net proceeds, Lender must ensure that the Applicant will not suffer severe cash flow or liquidity problems when the taxes come due." In plain words, if nothing was withheld at the time of the sale, that lender's underwriter looks at whether the money you have left after closing can cover the tax bill when it arrives.

So the gain on the statement and the cash you can spend on the home can be two different figures, and the second one is the one we plan the purchase around.

Can vested stock options count as mortgage reserves?

Yes, and under the agency rule you do not have to exercise them to count them.

Reserves are the money you still have after the loan closes, measured in months of the new payment. The post on what counts as mortgage reserves covers how they are counted. Fannie Mae's B3-4.3-01 closes its stock section with one sentence for reserves: "When used for reserves, 100% of the value of the assets (as determined above) may be considered, and liquidation is not required." For an option grant, the value "as determined above" is the gain on exercise, so the whole gain counts and the options stay unexercised.

Luxury Mortgage's guidelines set a different figure for its own loans: "Vested Stock Options are acceptable for reserves at 70% of the current market value limited to the strike price value." That is this lender's rule for its non-agency products, written in its own words, and it is not the agency rule. In plain terms, that lender counts 70 percent of the value toward your reserves instead of the full amount. The rest of the sentence sets an upper limit tied to your strike price, and I'll get the exact figure from the lender using your grant statement so you know your number before you exercise anything. The non-QM page covers when a non-agency loan is the right fit.

The steps, in order

1. The grant statement. The current statement from your equity plan is the starting point, and only the options marked vested go into the count. You'll want the option price written next to that count, because you need both numbers to work out the gain.
2. The gain. The lender subtracts the option price from today's stock price and multiplies the result by the number of vested options, and that is the figure your file uses.
3. The cash the closing needs. Down payment, closing costs and prepaid items, less the savings you plan to use. Closing costs explained covers what goes into that total.
4. The 20 percent test on a conventional file. The lender compares the gain with 1.2 times the cash you need from it. If the gain clears it, documentation of the sale is not required before approval and the timing of the exercise stays with you.
5. The tax conversation with your tax professional, before the exercise order goes in.
6. A single transfer of the proceeds. The money goes in one transfer to the account the closing will be funded from, so the deposit matches one trade confirmation. The post on bank statements and the paper trail covers why that matters once the money lands.

Mistakes that cost a week

Counting the unvested options. Fannie Mae says they should not be entered on the loan application, so a figure that includes them gets rebuilt at underwriting.

Multiplying the share price by the option count. The file uses the gain, so a statement showing a large share value can carry a much smaller asset once the option price comes out of it.

Planning the whole gain as spendable. The option price has to be paid, and the taxes come due. The cash you can put toward the home is what is left after both.

Exercising the week of closing. The cash has to settle in the brokerage account, move to your bank, clear the bank's hold on incoming funds and then wire to the closing office. The exercise date belongs on the calendar early.

Moving the proceeds in pieces. The lender asks about each transfer separately, so one transfer that matches the trade confirmation keeps it to a single explanation.

An illustration, with invented numbers

Numbers below are made up to show the mechanism. None of them is a quote or a rate.

Say you hold 3,000 vested options with an option price of $20, and the stock trades at $52 today. You are buying at a price where the cash to close is $70,000, and you have $21,000 in savings that you plan to use.

THE GAIN ON EXERCISE
Current stock price                         $52
Option price                               -$20
                                          ------
Gain per option                             $32
Vested options                            x3,000
                                          ------
Gain the file counts                     $96,000

THE CASH THE CLOSING NEEDS
Cash to close                            $70,000
Savings you plan to use                 -$21,000
                                          ------
Needed from the options                  $49,000

THE 20 PERCENT TEST
Needed from the options                  $49,000
Times 1.2                                   x1.2
                                          ------
Gain that clears the test                $58,800

The gain of $96,000 clears $58,800 with room to spare. On a conventional file, documentation of the sale is not required before approval, and the exercise date is yours to set.

Now the reserves. Using $49,000 of the gain for the closing leaves $47,000 of gain on options you have not exercised. Under Fannie Mae's rule that $47,000 counts at 100 percent toward reserves, unexercised. Against a new payment of $3,100 a month, that is about 15 months of reserves, before counting a retirement account.

On a file with the lender whose guidelines set the 70 percent reserve rule, the lender would count 70 percent of the value toward reserves, within its limit tied to the strike price, and I'll get that exact figure from the lender before you exercise. The tax on the exercise comes out of your pocket separately, so if nothing was withheld, the months of reserves shrink by whatever the tax turns out to be.

Your next step

Rate & Best Fit prices the purchase for your scenario, so you can see the payment and the cash to close before deciding how many options to exercise. You choose a rate option there, and that selection can change as your file comes together.

Calls are welcome too. If you send me the grant statement, I can tell you what the gain counts for and which of my lenders reads it best for your purchase. A documented pre-approval is where that number gets written down once, so you know what you qualify for before you write an offer.

Common questions

Can I use vested stock options for a down payment on a home?

Yes. Fannie Mae's Selling Guide, section B3-4.3-01, treats vested stock options as an acceptable source of funds for the down payment, closing costs and reserves. Freddie Mac's guide section 5501.3 lists vested stock options among the securities a client can use. The lender documents the value from a statement that lists the number of options and the option price, and uses the current stock price to work out the gain from exercising the options and selling the stock.

How does a mortgage lender value stock options?

By the gain on exercise. The lender takes the current stock price, subtracts the option price, and multiplies by the number of vested options, following the method in Fannie Mae's section B3-4.3-01. The lender uses that gain, so the share price alone is never the figure. One of my lenders' non-agency guidelines counts that gain for down payment and closing costs when the options are immediately available. For reserves, the same guidelines count vested stock options at 70 percent of the current market value limited to the strike price value, in that lender's own words.

Do unvested stock options count toward a mortgage?

No. Fannie Mae's section B3-4.3-01 says non-vested stock options are not an acceptable source of funds for the down payment, closing costs or reserves and should not be entered on the loan application. Freddie Mac's section 5501.3 says stock with limitations on its accessibility, such as restricted stock that has not vested and been distributed, is not eligible. Options that vest later can be used once the statement shows them as vested.

Do I have to exercise my stock options before closing on a mortgage?

The proceeds have to reach the closing, so an exercise and sale happens at some point. On a conventional file, Fannie Mae's section B3-4.3-01 does not require documentation of the actual receipt of funds when the verified value clears a cushion. That cushion is a value at least 20 percent more than the amount of funds needed for the down payment and closing costs. Below it, the file documents the sale and the money arriving.

Can vested stock options count as mortgage reserves?

Yes. Fannie Mae's section B3-4.3-01 allows 100 percent of the value of the asset, meaning the gain on exercise, to count toward reserves, and says liquidation is not required, so the options stay unexercised. Lenders writing their own non-agency rules can set a different figure; one of my lenders' guidelines counts vested stock options for reserves at 70 percent of the current market value limited to the strike price value. Non-vested options do not count toward reserves under either rule.
