How Investment Assets Work for Your Mortgage
When you apply for a mortgage, your investment portfolio can serve as a valuable source of funds. Fannie Mae accepts stocks, stock options, bonds, and mutual funds as legitimate assets, but they want to see proof that these investments are real and that you actually own them.
The key requirement is verification. Your lender needs to confirm both the value of your investments and your ownership of them. This isn't just about having money on paper — it's about having assets you can actually access when needed.
Say you have $150,000 in a diversified portfolio of stocks and mutual funds, and you need $100,000 for your down payment and closing costs. Your lender will verify the current value of your portfolio and confirm that you own these accounts. If your portfolio value exceeds your needs by at least 20%, you won't need to prove you actually sold the investments before closing.
What Documents Your Lender Needs
For stocks and mutual funds, your lender must obtain either a recent account statement from your brokerage firm or a verification letter directly from the financial institution. The statement needs to show current values and must be recent enough to reflect current market conditions.
Stock options require different documentation. The lender needs proof that your options are vested, not just granted. This typically comes from your employer's stock plan administrator or the plan documents themselves. Unvested options don't count because you can't access them yet.
Government bonds get valued at their purchase price unless you can provide documentation showing their current redemption value. This might be a statement from the Treasury or your financial institution showing what the bonds are worth if you cash them in today.
For all investment types, you'll need to prove ownership. This means the accounts must be in your name (or jointly with a co-borrower). Statements showing someone else as the account holder won't work, even if they promise to give you the money.
Why Fannie Mae Has These Rules
Investment values fluctuate daily, which creates risk for lenders. By requiring recent documentation, Fannie Mae ensures that the asset values used in your loan approval reflect current market reality, not outdated information.
The ownership verification requirement prevents fraud. Lenders have seen cases where borrowers claimed assets they didn't actually own or couldn't access. Requiring proof of ownership in the borrower's name eliminates this risk.
The 20% buffer rule recognizes that you might not want to liquidate investments unnecessarily. If your portfolio value significantly exceeds your cash needs, Fannie Mae assumes you have adequate resources without forcing you to sell. This protects borrowers from having to realize capital gains or disrupt their investment strategy just to satisfy documentation requirements.
The 20% Rule and When You Must Prove Liquidation
Here's where things get practical. If your investment assets are worth at least 20% more than the funds you need for down payment and closing costs, you can keep your investments intact. The lender accepts their value without requiring proof that you converted them to cash.
Let's say you need $80,000 for down payment and closing costs. If your investment accounts total $96,000 or more (20% above $80,000), you're done. No need to sell anything or prove liquidation.
But if your investments are worth less than that 20% buffer, you must provide evidence that you actually received cash from selling them. This means bank deposit slips, wire transfer confirmations, or other proof that the sale proceeds landed in your account.
This rule creates a practical choice. You can either maintain a comfortable cushion above your needs, or you can liquidate investments and document the cash flow. Many borrowers prefer the first option to avoid triggering taxable events.
When Investment Assets Get Complicated
Market volatility can create timing issues. If you provide statements showing sufficient value, but the market drops before closing, your lender might require updated documentation. This is why many borrowers provide statements showing values well above the minimum threshold.
Margin accounts add another layer of complexity. If you've borrowed against your investments, the lender must subtract the margin debt from the account value. A $200,000 portfolio with a $50,000 margin loan only counts as $150,000 in assets.
Joint accounts require all account holders to be borrowers on the loan. If you own investments jointly with someone who isn't applying for the mortgage, those assets typically can't be used. The exception is when the non-borrowing account holder provides a gift letter, but this converts the transaction into a gift situation with its own requirements.
Stock options from your employer might have restrictions beyond vesting. Some companies prohibit sales during certain periods or require approval for large transactions. Your lender needs to understand these restrictions to determine if the options are truly accessible.
Using Investments for Reserves
The rules change when you're using investments for reserves rather than immediate cash needs. For reserves, you can count 100% of the investment value without any requirement to liquidate. This makes sense because reserves are meant to be available if needed, not necessarily converted to cash immediately.
Say your lender requires six months of mortgage payments in reserves, totaling $18,000. Your $25,000 stock portfolio satisfies this requirement completely. You don't need to sell the stocks or prove you can access the cash — the account value alone is sufficient.
This distinction matters for tax planning. Using investments for reserves lets you maintain your portfolio without triggering capital gains, while using them for down payment might require actual sales if you can't meet the 20% buffer rule.

Stocks, Stock Options, Bonds, and Mutual Funds
Vested assets in the form of stocks, government bonds, and mutual funds are acceptable sources of funds for the down payment, closing costs, and reserves provided their value can be verified. The lender must verify the borrower’s ownership of the account or asset. The value of the asset and any related documentation must meet the requirements outlined in the table below.
Stocks and mutual funds
The lender must determine the value of the asset (net of any margin accounts) by obtaining either
Stock options
The value of vested stock options can be documented by
Government bonds
The value of government bonds must be based on their purchase price unless the redemption value can be documented.
When 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 borrower’s actual receipt of funds realized from the sale or liquidation is required. Otherwise, evidence of the borrower’s actual receipt of funds realized from the sale or liquidation must be documented.
When used for reserves, 100% of the value of the assets (as determined above) may be considered, and liquidation is not required.
Refer to B3-4.3-03, Retirement Accounts, for the requirements pertaining to the use of retirement accounts for the down payment, closing costs, or reserves.
