Use A Margin Account In An Asset Depletion Mortgage — The Quick Read: A margin account can count toward an asset depletion mortgage, but the lender only credits the equity left after subtracting the outstanding margin loan — not the headline balance on the statement. Once that net figure is set, the usual asset haircuts and divisor still apply. Margin debt itself doesn’t disqualify the account. It just shrinks the pool the underwriter is willing to count.
Asset depletion mortgages exist for a specific kind of borrower: someone with real wealth sitting in accounts instead of a fat W-2. Founders, retirees, people a few years past selling a business — these files rarely turn on traditional personal-income documentation. They turn on statements. A margin-enabled brokerage account, though, throws a wrinkle into that math, and most borrowers don’t realize the wrinkle exists until it shows up mid-underwriting.
Key Takeaways
- Underwriters net the outstanding margin loan against the account’s market value before doing anything else — gross balance minus margin debit equals the figure that enters the file.
- Margin debt does not automatically disqualify an account. It’s a subtraction, not a red flag by itself — though heavy margin use invites more scrutiny.
- The remaining net figure still gets the standard asset-class treatment before it’s divided into qualifying income.
- Asset depletion products fit primary residences and second homes far more often than rental purchases; a rental purchase usually points toward a complete DSCR loans guide instead.
- Retirement accounts can’t carry margin at all — this entire conversation lives inside the taxable brokerage bucket only.
What Asset Depletion Is Actually Measuring
Asset depletion (sometimes called asset utilization) turns liquid wealth into a monthly qualifying figure. It doesn’t rely on pay stubs or traditional personal-income documents. A lender takes eligible liquid assets and applies a discount based on asset type. Then it divides what’s left by a set number of months. This produces income the file can use.
The regulatory backdrop here may help explain why lender formulas can vary. Before 2021, mortgage underwriting for these files often leaned on a fixed federal framework known as Appendix Q. That framework was replaced with a more flexible “consider and verify” standard. This is part of why non-QM asset depletion programs today tend to build their own divisors and haircuts, rather than following one government-set formula.
That flexibility is exactly why margin treatment varies by program — and why getting the mechanics right before applying matters more than most borrowers expect.
How Underwriters Actually Read A Margin Account
A margin account isn’t a different type of asset. It’s an ordinary brokerage account with one added feature: the broker-dealer has extended credit against the securities inside it. Federal Reserve Regulation T built this credit line specifically to limit how much broker-dealers can lend against securities. The rule dates back nearly a century and still governs every margin loan today.
The practical result for a mortgage file: whatever the borrower has borrowed against that account is money they don’t actually control free and clear. It’s pledged. So the underwriter’s first move isn’t a haircut — it’s subtraction.
Here’s the sequence, step by step:
1. Pull the full statement, not a balance summary. The underwriter needs to see the margin loan balance line, not just the top-line account value.
2. Net the margin debit against the market value. Gross securities value minus outstanding margin balance equals net equity — the figure that actually belongs to the borrower.
3. Apply the standard asset-class discount to what’s left. Taxable brokerage holdings, retirement funds, and cash each get treated differently once the netting is done.
4. Divide the eligible balance by the program’s divisor. That produces the monthly figure the file uses to qualify.
5. Document the whole chain. Custodian name, account holder, positions, and the margin balance line all need to be visible on the same statement.
A margin loan drawn as cash and moved into checking for a down payment is a separate question entirely — that’s a large-deposit sourcing issue, not a depletion-math issue, and it needs its own explanation trail.
The Math: Statement Value Versus What Actually Counts
Picture a brokerage account showing a healthy six-figure-plus balance on the summary page. If there’s an active margin loan against it, that summary number isn’t the number a lender will use.
| Line Item | What It Represents |
|---|---|
| Headline account value | Gross market value of all securities in the account |
| Margin loan balance | Amount borrowed against those securities, per Reg T and the broker’s own maintenance rules |
| Net equity | Headline value minus margin balance — the figure that enters underwriting |
That net equity figure is what then gets whatever discount the specific program applies to taxable brokerage assets, before the divisor step. Skip the netting step in your own planning, and it’s easy to walk into an application thinking there’s far more usable capital than the file will actually reflect.
This is the point where a lot of borrowers get tripped up: they assume the account statement is the asset. It isn’t. The lien against it is real debt, even though it doesn’t show up as a monthly payment anywhere.
Key Terms Defined
Margin account — a brokerage account where the broker-dealer has extended credit against the securities held inside it, allowing the investor to borrow against their portfolio.
Asset depletion (asset utilization) — a mortgage qualification method that converts liquid wealth into monthly qualifying income by dividing discounted assets over a set number of months, instead of using traditional personal-income documentation or pay stubs.
Haircut — the discount a lender applies to a specific asset type to account for market volatility before counting it toward qualification.
Divisor — the number of months a lender divides eligible assets by to produce the monthly income figure used in underwriting.
LTV (loan-to-value) — the loan amount expressed as a percentage of the property’s value; it’s the leverage ceiling a program will allow.
Business-purpose loan — a loan made for an investment property rather than a primary residence, reviewed under a different framework than a standard owner-occupied mortgage.
Tradeoffs And What Can Go Wrong
Margin inside an asset depletion file isn’t automatically a problem — but it introduces three specific risks worth sizing before an application goes in.
Concentration risk gets flagged harder. A margin-heavy position in a single stock or narrow sector reads differently to an underwriter than a diversified account sitting in cash and bonds. Heavy margin use paired with concentration is a combination underwriters treat as added risk, not a neutral fact on the file — expect a request for a narrative explaining the holdings.
Timing matters more than borrowers expect. Paying down a margin balance before submitting a file increases net equity and can strengthen the depletion math. Leaving it in place doesn’t disqualify the account, but it does shrink the number that survives the netting step — worth running both scenarios before deciding.
A margin call mid-file is disruptive. If the market moves against a margin position while a loan is in underwriting, the broker-dealer can force a sale to restore the required maintenance margin — under FINRA rules that maintenance threshold sits at 25% of current market value, on top of the 50% initial margin requirement under Reg T. A forced liquidation changes the account balance the lender is relying on, sometimes after the file has already been submitted.
Restricted or illiquid shares muddy the picture. Not everything in a margin-enabled account is actually marginable. Unvested restricted stock, privately held shares, and similar positions generally can’t be pledged for margin in the first place — so a margin balance is really a signal that at least part of the account is freely tradable, but the underwriter still has to separate what’s eligible from what isn’t.
Who This Fits — And Who It Doesn’t
Asset depletion built around a margin-enabled brokerage account fits a fairly specific profile. It works best for someone buying or refinancing a primary residence or second home, with real wealth sitting in accounts rather than salary. It doesn’t fit rental property acquisition nearly as often.
Across the wholesale network Lendmire places files through, this program runs from $300,000 loan amounts up to $6,000,000 on a portfolio non-QM path, with a separate bank portfolio track carrying twelve-month bank-statement files as high as $30,000,000 on its own leverage ladder — roughly 65% at the lower end of that ladder, stepping down to 60% and then 55% as loan size climbs toward $30,000,000, typically subject to underwriting.
On a primary residence, leverage on the standard asset depletion path steps down as the loan size grows — commonly around 90% at the lowest size band, working down through the mid tiers, to roughly 65% once a loan crosses into the $4,000,000-to-$5,000,000 range, with everything above $4,000,000 reviewed case by case before submission. Second homes generally run about five points lower at every size band than the comparable primary-residence figure. These are ceilings through select wholesale programs, not guarantees, and every file still goes through full underwriting.
The asset side has its own structure. An asset-allowance path divides liquid assets by 36, 60, or 84 months depending on the debt-to-income picture and loan size, while an assets-only path skips DTI altogether but requires liquidity roughly equal to the loan amount plus closing costs. Retirement money typically counts at 70% of value, rising to 80% once the borrower is past 59½ — a meaningfully different treatment than a taxable brokerage account, which is generally counted at full value once margin debt has been netted out. Business funds, most trusts other than a revocable living trust, unvested stock, and cryptocurrency generally don’t count at all on this program.
Reserve requirements scale with loan size too. Smaller loans commonly need three months of payment reserves. That number moves to six, then nine months, as the loan amount climbs. Borrowers also need additional months of reserves for each other financed property in their portfolio.
Now, the part that trips people up: if the goal is buying a rental property, this entire product is usually the wrong tool. Asset depletion reads the borrower’s balance sheet. A rental purchase is better served by a loan that reads the property’s own income instead — which is exactly what a DSCR loan is built to do. DSCR stands for debt-service coverage ratio: it measures whether the property’s rent covers its own monthly obligation, expressed as a ratio rather than a personal-income test. Most DSCR programs are built around a 1.00x coverage benchmark because at that level rent covers the payment in full, though select lenders in Lendmire’s network will review coverage below that threshold with adjusted leverage, subject to lender guidelines. None of that changes the margin-account math above — it just means the account usually belongs in a different file type depending on what’s being financed.
Some borrowers have both a primary residence purchase ahead of them and a rental portfolio behind them. For these borrowers, it’s common to use a margin-funded brokerage account to strengthen the asset depletion side of the file on the home purchase. Meanwhile, separate retirement holdings get evaluated under different reserve rules on the investment side. Keeping the two buckets straight — which account funds which loan, and under which program’s rules — tends to be where files run smoothly or run into trouble.
This is not legal or tax advice. Margin borrowing carries real securities-market risk independent of the mortgage file. Anyone weighing whether to draw on margin, pay it down, or restructure holdings before applying should talk with a qualified financial advisor, attorney, or CPA about their specific situation before making that call.
Frequently Asked Questions
Does having margin debt on my brokerage account disqualify me from asset depletion?
No. A margin balance on its own doesn’t disqualify the account. The lender simply nets the outstanding margin loan against the account’s market value first, then applies the usual asset treatment to what’s left. The account only becomes a problem if the net equity, once discounted, isn’t enough to support the loan.
Should I pay down my margin balance before applying?
It often helps, since a lower margin balance means more net equity survives the subtraction step — but whether it’s worth doing depends on your broader liquidity needs and DTI picture. Running the numbers both ways, with and without a paydown, before deciding is generally the more useful move than guessing.
Can I use a margin loan to fund my down payment on an asset depletion purchase?
You can draw margin as cash for a down payment, but that draw becomes a new liability and a sourced deposit that underwriting will want documented — it’s a separate question from the depletion calculation on the account itself. It doesn’t disappear from the file just because it originated inside a brokerage account.
Why doesn’t asset depletion work well for buying a rental property?
Asset depletion reads the borrower’s personal balance sheet, which is the wrong lens for an investment purchase. Rental property financing more often runs through a DSCR loan, which qualifies primarily on the property’s own rental income covering its payment, subject to lender guidelines — not on the buyer’s brokerage or retirement holdings.
Can I put margin on a retirement account instead of a taxable brokerage account?
No. Margin borrowing isn’t permitted inside IRAs or most qualified retirement plans. This entire margin-account conversation applies only to taxable brokerage holdings — retirement money is underwritten separately, with its own age-based discount.
