Asset depletion solves a specific problem: a borrower with substantial liquid assets but insufficient documented income. Rather than reject the file or demand a co-signer, asset depletion programs allow lenders to count down those assets as qualifying income over the loan term. For a first-time non-QM submission, the math feels backward—you’re converting a pile of money into monthly cash flow. This article walks through the exact calculation, the documentation threshold, and the investor overlays that will trip you if you’re not precise.

The Asset Depletion Formula: What You’re Actually Calculating
Asset depletion works like this: take the borrower’s liquid assets (bank statements, brokerage accounts, money market, CDs—not illiquid holdings like real estate or retirement accounts that have penalties), divide by the number of months remaining on the loan term, and add that monthly amount to income for debt-to-income qualification.
The formula itself is straightforward: (Total Qualifying Assets ÷ Loan Term in Months) = Monthly Qualifying Income. But the “qualifying assets” part is where most submissions fail on first review. Not every dollar in an account counts. Seasoning rules, minimum balances, account type restrictions, and investor overlays all narrow the pool.
Seasoning and Account Age
Most investors require that liquid assets be seasoned for a minimum of 60 days before the application date. This means the money can’t be a gift, a loan, or freshly liquidated from a restricted source. The lender will order bank statements covering the full seasoning period—typically three months of statements minimum—to confirm the balance was genuinely available during that window. If your borrower deposited $80,000 into checking 45 days before application, that amount does not count. Wait the full 60 days and resubmit.
Some investor guidelines allow a one-time gift for down payment or closing costs, but that same generosity does not extend to assets used for qualification. Segregate them mentally: a gift for down payment pages, a seasoned bank balance for income calculation. The bank statements will make this clear—look for deposits without a corresponding source and flag them.
Account Types and Exclusions
Retirement accounts (401k, traditional IRA, Roth IRA, SEP-IRA, Solo 401k) are excluded because withdrawal before age 59½ incurs a 10% penalty plus ordinary income tax. Most investors do not allow you to net out those penalties and count the remainder. The account simply does not qualify. Same rule typically applies to:
- Health savings accounts (HSA)
- 529 education savings plans
- Stocks held in individual portfolios (depends on investor—confirm first)
- Cryptocurrency and digital assets (most investors exclude entirely)
- Life insurance cash surrender value (excluded by most programs)
Checking, savings, money market, CDs, and brokerage accounts holding traditional securities (stocks, bonds, mutual funds) typically qualify. If the investor allows brokerage assets, they’ll often require a recent statement showing market value and a standard risk factor applied—20% haircut on equity mutual funds is common.
Minimum Balance Thresholds
Some investors set a floor: assets must exceed a certain amount to be counted at all. You might see a guideline stating “assets must be $25,000 or greater to qualify.” If the borrower has $23,000, zero counts. This is different from seasoning—it’s a binary gate. Always read the specific investor guideline for this trap.
Worked Example: From Balance Sheet to DTI Calculation
Say your borrower is a consultant with $180,000 in a seasoned savings account, a $50,000 IRA (excluded), and documented consulting income of $3,200 per month. The loan amount is $400,000 on a 30-year term (360 months).
Step 1: Identify qualifying assets. $180,000 in savings qualifies; the IRA does not. Qualifying assets = $180,000.
Step 2: Calculate monthly asset depletion income. $180,000 ÷ 360 months = $500 per month.
Step 3: Add to documented income. $3,200 (consulting) + $500 (asset depletion) = $3,700 total qualifying income.
Step 4: Calculate housing expense and total DTI. Assume the housing payment (PITI + insurance + taxes) is $2,200. Total monthly debt (housing + other obligations) might be $2,700. DTI = $2,700 ÷ $3,700 = 72.97%.
At 72.97% DTI, this file will not qualify under a 50% DTI overlay—a common non-QM guideline. But some investors allow up to 75% or higher with compensating factors. This is where asset depletion becomes a negotiation: the lender is saying, “Yes, your income is thin now, but you have enough assets to sustain the payment over the full loan term.” The cushion is real, which is why the guideline exists. The investor accepts higher DTI because the risk profile differs from a pure income-based qualification.
Documentation Requirements: What the Lender Will Demand
Non-QM loans built for asset depletion require a full history, not a snapshot. Expect to order:
- Three months of bank statements for every account you’re using (to confirm seasoning and average balance)
- A signed letter from the borrower explaining the source and seasoning of the funds
- For brokerage accounts, an account statement with the market value of securities as of the date of valuation
- A calculation worksheet (many lenders use a standardized form) showing qualifying assets, the depletion period, and monthly income derived
The bank statements are not optional detail—they become a control. If the statements show the balance fluctuating wildly, or if large deposits appear without explanation, the underwriter will ask for gift letters, sales proceeds documentation, or other proof. An account that looks like a dumping ground for untraced deposits will be rejected entirely or the balance capped at the lowest three-month average.
For first-time asset depletion submissions, provide the calculation worksheet proactively. Do not make the underwriter hunt for the math. Show the qualifying assets line-by-line, the seasoning dates, the term, the result. This speeds approval and reduces re-trade risk.
Investor Overlays and Gotchas
Asset depletion guidelines vary materially by wholesale lender. One investor might allow it freely to 75% DTI; another might cap it at 55% DTI or require a minimum asset reserve remaining at payoff. Always pull the current guidelines before underwriting, because overlays shift quarterly.
Common overlays to watch:
- Residual assets requirement: Some investors demand that after the asset depletion term, the borrower retain a minimum amount—often 10% of the original balance or a set dollar floor like $25,000. This makes the math tighter: you divide by 360 months only if the borrower can afford to keep a reserve.
- Loan-to-value (LTV) interaction: High-LTV files (90%+) sometimes face restrictions on asset depletion or require larger reserves. Confirm that your 85% LTV file doesn’t carry a hidden “asset depletion only at 80% LTV or below” overlay.
- Rate/term impact: Asset depletion files may carry rate hits (8-25 basis points higher) or term restrictions (20-year fixed, not 30-year ARM). The risk premium is baked in, so price accordingly and set expectations with your broker-partner.
- Occupancy restrictions: A few programs restrict asset depletion to owner-occupied properties only, excluding investor or second-home scenarios. Verify occupancy status is aligned with the guideline.
Non-QM loans exist because they fall outside the Consumer Financial Protection Bureau‘s Qualified Mortgage (QM) rule under the Ability-to-Repay standard. That freedom is why asset depletion programs can exist—they’re designed for borrowers who don’t fit traditional income-based qualification. But it also means every investor writes their own interpretation. Confirm your specific investor’s current overlay before submitting a file.
Common Pitfalls in First-Time Submissions
Mixing asset depletion with other alternative income streams is where files get bogged down. If your borrower has bank statement business income, gig income, and asset depletion, each income stream needs separate documentation and calculation. Do not combine them into a summary. Lay out the income sources in separate sections of the 1003 and the underwriting file. This prevents confusion and keeps the file organized for investor review.
Second pitfall: using the wrong loan term for the calculation. Asset depletion is calculated on the note term, not the amortization period or a partial-interest-only schedule. A 30-year fixed-rate loan is 360 months for depletion purposes. A 5/1 ARM is still 360 months (you calculate across the full 30-year term, not just the 5-year fixed period). Confirm the exact term in the investor’s loan estimate before you finalize the calculation.
Third: failing to address account volatility in your write-up. If the savings account shows a $50,000 deposit three weeks before application, that needs explanation in the borrower’s letter. The underwriter will ask anyway—get ahead of it. A brief note (“These funds represent my annual consulting retainer, paid in a lump sum in November”) closes the loop and prevents a second request for documentation.
Frequently Asked Questions
Can I use retirement account cash surrender value or a loan against a 401k for asset depletion?
No. Retirement accounts are excluded from most asset depletion guidelines because withdrawal triggers penalties and taxes. A loan against a 401k might be documentable as income in some programs, but not as an asset for depletion purposes. Treat retirement accounts as off-limits for non-QM asset depletion submissions unless the specific investor guideline explicitly allows otherwise—which is rare.
What if the borrower’s assets are spread across five different banks?
You aggregate them for depletion calculation. Gather three months of statements from each account, confirm seasoning on all of them, total the qualifying balances, and calculate the monthly income using that sum. The documentation burden increases, but the math stays the same. Organize the statements in the file clearly—one tab per institution, dates labeled—to make the underwriter’s job easier.
Does the asset depletion income count toward qualifying for mortgage insurance or investor program overlays?
It counts for debt-to-income qualification in most programs, but some guidelines carve out specific uses. Mortgage insurance (PMI) premiums are typically calculated on the total qualifying income including asset depletion. However, some investor overlays may apply different treatment—a guideline might say “minimum credit score 680 if DTI exceeds 60% and asset depletion comprises more than 20% of income.” Always confirm how the asset depletion income is treated across all program requirements—QM-like overlay rules, pricing grids, and investor credit policy.
What happens if the borrower’s assets depreciate sharply after closing?
That’s a borrower risk, not a lender risk. Once the note is funded, the lender has the promissory note and deed of trust. The fact that the borrower’s brokerage account dropped 20% in value post-closing does not create a lender remedy. This is why some investors cap the portion of DTI that can come from asset depletion or require a documented financial plan—to reduce the chance that the borrower ends up unable to pay when the cushion erodes. As the broker, you are not liable for post-closing market shifts, but you should communicate the risk clearly to your borrower so they understand what they’re signing.
Can asset depletion be used on a co-borrower’s assets, or only the primary borrower?
Most programs allow co-borrower assets to be included in the pool for depletion. However, if the co-borrower will not be obligated on the note, some investors restrict that—because the co-borrower’s assets are not legally tied to the obligation. Confirm with your investor whether co-borrower assets are allowed and under what conditions (typically the co-borrower must be on the note and title). If using only one spouse’s assets, make sure the asset account is titled in a way that doesn’t complicate title clearing.
Wrapping Up: The Takeaways
Asset depletion converts a balance into income by dividing total qualifying assets by the loan term in months. The math is simple; the documentation and overlays are where precision matters. Seasoning rules, account-type restrictions, and investor-specific overlays all reduce the amount you can actually count. On your first submission, order full bank statements, prepare a signed calculation worksheet, and confirm your investor’s exact guideline on residual assets, LTV interaction, and rate impact. The program exists for a reason—it works for borrowers with liquid wealth and thin documented income. Use it correctly and it closes files that would otherwise stall.
