An underwriting method that converts eligible net assets into a monthly qualifying-income amount.
Asset depletion is an underwriting method that converts eligible net assets into a monthly income amount for mortgage qualification. It can help an asset-rich borrower whose regular employment, retirement, or investment income is not enough to support the requested loan under ordinary income rules.
The name describes an assumed drawdown for calculation purposes. It does not necessarily require the borrower to withdraw that amount every month after closing.
Traditional underwriting compares recurring Qualifying Income with monthly obligations. That approach can understate repayment capacity for a retired or financially independent borrower who holds substantial eligible assets but receives limited scheduled income.
Asset depletion offers a structured alternative. The lender identifies assets allowed by the program, subtracts amounts that cannot support the calculation, and spreads the remainder over a prescribed number of months. The resulting figure is treated as monthly qualifying income for the underwriting test.
This method is not available for every borrower, asset, occupancy, loan purpose, or loan-to-value level. Eligibility and calculation rules vary by program and lender.
Asset depletion is usually discussed during preapproval when a standard income calculation falls short but the borrower has significant assets. During underwriting, the lender performs Verification of Assets and confirms ownership, access, current value, and permitted asset type.
The lender must also separate money needed for the transaction and any required reserves. The same asset dollars generally cannot fund closing, satisfy reserves, and remain fully available for the income calculation.
A common structure is:
Here, I_m is the monthly asset-based income, A_n is eligible net assets, and N is the program divisor in months. Eligible net assets are calculated before applying the divisor:
In the second formula, A_e is accepted eligible assets and D is required deductions. Those deductions may include funds used for the down payment and closing costs, required reserves, and applicable withdrawal penalties or other program adjustments. The exact asset list and divisor are not universal.
For example, one conventional method for eligible employment-related assets divides net documented assets by the mortgage’s amortization term in months. A 30-year term therefore uses 360 months. Other asset-depletion products may use a different divisor, discount, age rule, or asset list.
Suppose a program accepts the following calculation:
| Calculation step | Amount |
|---|---|
| Eligible documented assets | $600,000 |
| Less applicable penalties or adjustments | -$30,000 |
| Less down payment, closing costs, and required reserves | -$120,000 |
| Eligible net assets | $450,000 |
If that program divides by a 360-month loan term:
The underwriting income is $1,250 per month, not $600,000 ÷ 360. Funds assigned to closing and reserves are removed first. The borrower still must satisfy the program’s credit, property, occupancy, and other requirements.
| Asset question | Why it changes the calculation |
|---|---|
| Is the asset an eligible type? | Some methods permit only specified retirement or employment-related assets |
| Does the borrower own it? | Joint ownership may require the co-owner to be a borrower |
| Is it vested and accessible? | Restricted or unavailable funds may be excluded |
| Is a withdrawal penalty applicable? | The penalty may reduce net assets even if no withdrawal is planned |
| Is part of the account needed to close? | Transaction funds cannot remain in the income pool |
| Is the asset already producing counted income? | Programs may prevent using the same asset twice |
Checking and savings balances are not automatically eligible for every asset-depletion method. Conversely, retirement assets may qualify only if access and program conditions are met. The lender’s written program definition controls.
These questions make lender quotes easier to compare because two products can turn the same portfolio into different monthly qualifying amounts.
Qualifying Assets are assets accepted for a mortgage purpose. Asset depletion is one specific use that converts a subset of those assets into income.
Cash Reserves measure post-closing cushion. Asset-depletion income enters the affordability calculation, while reserves remain assets.
Liquid Assets describes accessibility. Liquidity alone does not establish eligibility for an asset-depletion program.
Retirement or investment income is an actual payment stream or earnings source. Asset depletion is a lender calculation and may exist even when the borrower takes no corresponding monthly distribution.
An Asset Qualifier Mortgage may apply a separate sufficiency test to eligible net or post-closing assets instead of converting them into monthly income. Some lenders use asset qualifier, asset utilization, and asset depletion loosely, so the written calculation controls.
