How asset depletion converts a balance into qualifying income

A mortgage broker’s file sits on your desk: strong payment history, solid credit, but the borrower’s income is too thin. They have $400,000 in liquid savings—money sitting there, real and verifiable. The problem is that a savings balance isn’t automatically income. So how does a borrower tap that cushion to qualify for a loan? Asset depletion converts that lump sum into a calculable monthly income figure that investors will recognize and underwrite. This method is not new, but it remains one of the most misunderstood tools in Non-QM underwriting. The calculation itself is straightforward; the gotchas are in the details.

The Core Mechanic: How the Math Works

Asset depletion takes a liquid asset balance and divides it by a stated time horizon—typically 240 months (20 years), but some investors use 360 months (30 years). The result is a monthly income equivalent.

Formula: Liquid Assets ÷ Number of Months = Qualifying Income

Say a borrower has $300,000 in savings (liquid, verified via bank statements, no liens or encumbrances). Using a 240-month depletion schedule:

$300,000 ÷ 240 = $1,250/month qualifying income

That $1,250 appears as income on the asset depletion calculation and factors directly into the debt-to-income ratio. If the borrower has a $2,000 mortgage payment and another $500 in obligations, the total monthly obligation is $2,500. With the $1,250 from asset depletion plus $3,000 from W-2 employment, the total qualifying income is $4,250, yielding a DTI of about 58%—which may be acceptable depending on the investor’s Non-QM overlays and the borrower’s reserves post-closing.

What Qualifies as a Depletable Asset

Not every asset can be depleted. Investors maintain specific rules:

• Savings and money market accounts: Fully depletable if liquid, no restrictions, and held for a minimum period (typically 60 days of seasoning).
• Checking accounts: Depletable, but operationally used; many investors cap the deductible balance at two months of listed monthly expenses to account for working capital.
• Certificates of deposit (CDs): Depletable, but early withdrawal penalties must be factored in unless the CD matures before closing.
• Retirement accounts (401k, IRA): Some investors allow depletable balances, but only after applying a haircut for taxes and early withdrawal penalties—typically 25% to 35% reduction.
• Investment accounts (taxable brokerage, stocks, mutual funds): May be depletable, but subject to a market volatility haircut, often 10% to 20%, and some investors exclude them entirely.

Assets that do not qualify: primary residence equity (no forced liquidation), retirement accounts without penalty haircuts (if the investor doesn’t allow them), pending litigation settlements, or funds held in trust for a third party.

The 20-Year vs. 30-Year Depletion Schedule Debate

The 240-month (20-year) schedule is the industry standard and aligns with the end of most 30-year mortgage terms—the theory being that the borrower’s assets would be substantially depleted by the time the loan fully seasons. However, some investors, particularly those in portfolio or bank-direct programs, accept 360-month (30-year) schedules to generate higher qualifying income and ease approval odds.

Using the earlier example with a 360-month schedule: $300,000 ÷ 360 = $833/month. That borrower qualifies with $250/month less income—meaningful when margins are tight.

A practical rule: confirm the depletion schedule with your specific investor before running the calculation. Some investors also impose age-based adjustments—for borrowers over 62, they may require a shorter horizon or apply no asset depletion at all.

The Reserve Requirement Complication

Here is where many brokers stumble: asset depletion balances cannot be double-counted. If a borrower uses $300,000 to calculate qualifying income, that balance (or a substantial portion of it) is typically earmarked as reserves post-closing. A borrower cannot simultaneously claim $1,250/month in income and retain $300,000 in unrestricted reserves.

Investors typically impose one of two approaches:

1. Reserve haircut: The depleted asset is reduced by the amount used for reserves. If the investor requires 12 months of PITI in reserves ($24,000 in this example), that $24,000 is deducted from the qualifying balance before applying the depletion formula. Result: ($300,000 − $24,000) ÷ 240 = $1,150/month income.
2. Separate reserve asset pool: Some investors allow the same asset to serve both purposes—it counts for qualifying income, and a separate pool (often a percentage of the depletion asset or a different asset entirely) is reserved. This is less common and carries stricter conditions.

Always review the investor’s asset depletion addendum to understand which approach applies and whether liquid funds are held in a segregated account or remain accessible.

Practical Underwriting Checklist

Before presenting an asset depletion file to the investor:

• Verify the asset is liquid and unencumbered (60+ days of bank statements, no liens noted).
• Confirm the asset type is permitted under the investor’s guidelines (many exclude non-depletable classes like equity or restricted retirement).
• Apply any required haircuts (retirement penalty, market volatility) before calculating.
• Deduct reserves per the investor’s formula before dividing by months.
• Document the depletion schedule in the file and the addendum (240 or 360 months).
• Confirm the resulting DTI, including the asset depletion income, meets the investor’s ceiling.
• Verify the borrower understands the reserve hold—reserves may be inaccessible for a stated period or restricted to specific withdrawals.

Common Investor Overlays That Affect Approval

Asset depletion is a Non-QM tool, meaning these loans fall outside the Consumer Financial Protection Bureau‘s Qualified Mortgage rule under the Ability-to-Repay standard, allowing investors more flexibility in how they assess borrower repayment ability. That flexibility comes with strings. Most investors impose overlays on asset depletion files:

• Minimum asset floor: Many investors require a minimum depletable balance (e.g., $50,000) to even consider the program.
• Maximum DTI cap: Allowing asset depletion income often raises DTI; some investors cap Non-QM files at 50% DTI even with depletion, while others go as high as 65% if reserves are strong.
• Age requirement: Some investors disallow asset depletion for borrowers over 65 or require a reduced schedule.
• Loan-to-value limits: Asset depletion files may be capped at 75% LTV or require a lower LTV to offset risk.
• Credit score minimum: Compensation factors may demand a higher credit floor (e.g., 640+) if asset depletion is the primary income engine.

These overlays vary significantly by lender. Always confirm current guidelines with your specific investor before structuring the file.

A Worked Example: Putting It Together

Imagine a borrower: $80,000 W-2 income ($6,667/month), $350,000 in a savings account (liquid, 90 days seasoned), age 52, seeking a $400,000 purchase with 20% down. Target rate: 6.5% (no specific offer, just a planning number).

Loan details: $320,000 principal, estimated PITI $2,100/month, taxes and insurance included.

Debts: $300 auto loan, $200 credit card minimum = $500/month.

Total obligations: $2,600/month.

Without asset depletion: DTI = $2,600 ÷ $6,667 = 39%. Likely approved for most Non-QM investors.

Now assume the borrower has thin W-2 income but the loan amount is higher and DTI would exceed limits. Asset depletion applies:

Depletable asset: $350,000, less 12 months reserves ($25,200) = $324,800 qualifying balance.

Monthly asset depletion income: $324,800 ÷ 240 = $1,353/month.

Total qualifying income: $6,667 + $1,353 = $8,020/month.

Revised DTI: $2,600 ÷ $8,020 = 32.4%. Well within Non-QM tolerances.

The borrower now qualifies for the loan—the asset depletion converted a cash cushion into measurable income, and the file moves forward with documented reserves of approximately $25,200, typically held in an escrow account or with a reserve agreement rider.

Frequently Asked Questions

Can the same asset count toward both qualifying income and down payment funds?

No. If an asset is deployed for the down payment, it cannot be included in the depletable balance for qualifying income. The broker must identify separate assets for each purpose—one pool for down payment/closing costs and a distinct pool for asset depletion income. This ensures clean accounting and compliance with investor reserve requirements.

What happens if the borrower’s liquid assets drop before closing or shortly after?

If the asset balance drops before closing, the depletion calculation must be recalculated based on the verified balances at the time of final underwriting review. Once closed, the reserved amount (typically held in escrow or via a rider) is frozen—the borrower cannot access those funds. Some investors allow modest fluctuations (within 5%), but a material drop often triggers a file re-submission or denial. Document the trend in your supporting file narrative.

Do retirement accounts require different treatment than savings accounts?

Yes. Retirement accounts (401k, traditional IRA, Roth IRA) that are accessed before age 59½ incur taxes and early withdrawal penalties, typically totaling 25% to 35% of the balance. Investors apply a haircut to reflect this reality. Say a borrower has a $100,000 IRA and the investor applies a 30% haircut: only $70,000 is treated as a qualifying asset. Some investors exclude retirement accounts entirely; always check the guidelines before proposing one.

Can asset depletion be combined with other income types on the same file?

Absolutely. Asset depletion is additive—it stacks with W-2 income, self-employment income (bank statement or tax return-based), rental income, Social Security, or pension income. The monthly total of all income sources is used to calculate DTI. This flexibility is a key Non-QM advantage and is why asset depletion can turn a marginal file into an approval.

What documentation is required to substantiate asset depletion income?

Two to three months of bank statements showing the asset balance, proof that no liens or security interests encumber the funds (title search or account custodian letter if applicable), and confirmation of seasoning (typically 60 days of ownership). Some investors request a sworn statement from the borrower affirming that no legal claims or restrictions apply. Outsourcing Processing’s platform allows you to organize and annotate these statements for clean file presentation to the investor.
