> When capital gains income for a mortgage counts, the two year history test, the assets needed to keep it going and how lenders view one-off sales.
Capital gains income can count for a mortgage only when it recurs. Lenders want two years of tax returns showing gains on Schedule D, proof the borrower still owns enough assets to keep selling, and a steady or rising trend. A single sale of a house or a block of stock is a one-time event, not income.

## When does capital gains income count for a mortgage?

Capital gains count for a mortgage when the borrower realizes gains year after year as a regular pattern, such as an active investor who trades a portfolio or a person who sells assets from a large holding each year. The lender is not counting the profit on one sale. It is counting a habit that is likely to repeat.

Fannie Mae's [Selling Guide topic on capital gains income](https://selling-guide.fanniemae.com/sel/b3-3.4-05/capital-gains-income) opens by calling capital gains generally a one-time transaction that should not be treated as stable monthly income. It then sets out how a lender can count them when the borrower relies on them: two years of signed personal returns with Schedule D, a two-year history, and evidence of assets that could be sold for future income.

### FHA's turnover test

The [HUD Single Family Housing Policy Handbook 4000.1](https://archives.hud.gov/offices/adm/hudclips/handbooks/hsgh/4000-1/HB-4000-1-2021-10-26.pdf) frames it as turnover. Capital gains or losses must be considered when the borrower has a constant turnover of assets that produces them. FHA asks for three years of returns to read the trend. A gain trend can be added to income; a consistent loss must be deducted.

### Borrowers who fit

- Retired investors who draw on a taxable portfolio by selling shares each year.
- Active traders whose returns show gains across many sales.
- Owners of a business that sells assets as part of its normal course, when those gains flow to the personal return.
- Employees who sell vested company stock on a schedule, though that is often handled under stock compensation rules instead.

## Two years of Schedule D gains and the averaging rule

Schedule D is the tax form that reports capital gains and losses, and it is the source document for this income. A conventional lender averages two years of net gains when the trend is steady or rising. When gains fell from the first year to the second, the lender uses only the most recent year.

### A worked example

All figures are examples. The borrower is a retired investor selling shares from a brokerage account.

| Year | Net capital gain on Schedule D |
| --- | --- |
| 2024 | 31,200 |
| 2025 | 34,800 |
| Two-year average | 33,000 |
| Monthly qualifying income | 2,750 |

Gains rose, so the lender averages both years: 66,000 ÷ 24 months = 2,750 a month.

### The same borrower with a falling trend

| Year | Net capital gain on Schedule D |
| --- | --- |
| 2024 | 34,800 |
| 2025 | 21,600 |
| Figure used | 21,600 |
| Monthly qualifying income | 1,800 |

Because gains fell, the lender uses only 2025 and qualifies the borrower on 1,800 a month. A lender may also ask why the gains fell before counting anything.

### Short-term and long-term gains

Schedule D separates gains on assets held a year or less from gains on assets held longer. Lenders generally use the net total, but the split helps the underwriter see the borrower's behavior. A return full of short-term gains points to active trading; a return with a few long-term sales points to planned withdrawals.

## Assets left to sell for future capital gains

Future gains need assets to sell. A lender counting capital gains must see that the borrower still owns a portfolio large enough to keep producing them. Fannie Mae asks for evidence that the borrower owns assets that could be sold if more income is needed for future mortgage payments, and that proof must be current under its document age rules.

### How the check works

Take the example borrower with 2,750 a month of qualifying gains. If the brokerage account holds 1.4 million in stocks and funds, a few years of 33,000 in gains is a small slice of it. If the account holds 60,000, two more years of the same sales would empty it. The second borrower's gains have no future.

### What counts as the portfolio

- **Brokerage statements** for the account the gains came from, showing current holdings.
- **Cost basis**, because a portfolio bought long ago holds more unrealized gain than one bought last year.
- **Other investment accounts** in the borrower's name.

[Brokerage statements for a mortgage](/blog/brokerage-statements-for-mortgage) covers which pages lenders want and how they read them.

### Concentrated positions

A large portfolio held in a single stock is weaker support than the same value spread across funds. One bad quarter can halve it, and a borrower who must sell to keep gains flowing may be selling at a loss. Underwriters do not usually apply a formal haircut for concentration under these rules, but they read the holdings page, and a file where most of the account is one employer's shares invites a closer look at whether the gains can really repeat.

### Assets double counted as reserves

The same portfolio often counts toward reserves. Lenders allow that, but a borrower should understand that selling down the account to raise a down payment can weaken the case for the income that depends on it.

## Is a one-off sale of stock or property income?

A one-off sale is not income for a mortgage. Selling a former home, a rental, a business or a concentrated stock position once produces a gain on the return, but nothing shows it will happen again. Lenders treat the proceeds as an asset, which may help with the down payment or reserves.

### Why the return can mislead

A borrower who sold a rental last year will show a large gain on Schedule D. Averaged with a year of no gains, that sale looks like steady income. It is not, and an underwriter who reads the return line by line will see that Form 8949 lists a single property sale behind the total.

### What the sale does help with

- **Down payment**, once the proceeds are sourced and seasoned.
- **Reserves**, if they sit in an account the lender accepts.
- **Debt payoff**, which can lower the borrower's ratio.

### Gains from a home sale

Profit on the sale of a main home is often partly or fully excluded from tax, so it may not appear as a gain at all. Either way, it is a one-time event and does not count as income.

## Brokerage sale proceeds on bank statements versus taxable gains

Brokerage sale proceeds arriving in a checking account are not gains. When a borrower sells shares and moves the cash to the bank, the deposit is the full sale price, including the original cost. Only the profit above cost is a capital gain, and only the return shows it.

### Reading the transfer

A bank statement line such as "BROKERAGE TRANSFER 15,000" tells the reviewer money left an investment account. It does not say what was sold or what it cost. A borrower who draws 15,000 every quarter might report 60,000 of withdrawals and only 18,000 of gains.

### Proceeds are not income either way

Some reviewers try to count regular brokerage transfers as income. That is the wrong method. The transfers show cash flow; the return shows gains. If a borrower is living on asset sales and the gains test fails, an asset depletion program may treat the account balance as the source instead.

### Keeping the two apart in analysis

When brokerage transfers land in the same account as pay or pension deposits, they inflate any deposit average. [TrueBankFlow](/) lets the reviewer exclude a deposit such as a brokerage transfer from qualifying deposits and recalculates the average at once, so the sale proceeds stay out of the income figure.

## Capital gains with a falling trend or recurring losses

A falling trend cuts the figure to the latest year or stops the income altogether. Recurring losses do something different under each agency. Fannie Mae says capital losses on Schedule D do not have to be counted against income or liabilities, even when they recur. FHA says a consistent loss must be deducted from total income.

### When a lender will stop counting

- Gains fell sharply and the borrower cannot explain why.
- The portfolio is too small to support more sales.
- Gains came from one or two large sales rather than steady turnover.
- The most recent year shows a net loss.

### Explaining a down year

A single weak year does not always end the story. A borrower who held cash through a market drop, or who sold less because they had other income that year, may show a dip followed by a recovery in the current year's statements. The lender will still follow its trend rule, which for Fannie Mae means using the lower recent year, but a clear letter of explanation helps the underwriter decide whether to count the income at all.

### Encoding the rule

Averaging rules like these are easy to state and easy to misapply by hand. Lending teams that write them into software use an [underwriting rules engine](/blog/underwriting-rules-engine) to pick the averaging method from the trend and flag a missing portfolio check.

### Other income with special rules

Capital gains are one of several income types that need their own test. [Boarder income for a mortgage](/blog/boarder-income-for-mortgage) depends on a shared household and a rent history, and [foster care income for a mortgage](/blog/foster-care-income-for-mortgage) depends on the agency placement. Each needs its own documents, and none can be read from deposits alone.
