The Quick Read: A margin loan is a loan from your brokerage secured by your securities, while an asset-based mortgage is a real-estate loan that counts your verified liquid assets as the whole qualification or as converted income, with the home as collateral. They solve different problems. The biggest difference is what happens to you when markets fall.
- A margin loan is a personal credit line against your portfolio. There is no mortgage file, no set paydown, and your brokerage can sell holdings if the account value drops.
- An asset-based mortgage is a regular purchase loan that is reviewed around assets instead of paycheck income, through select programs and subject to underwriting.
- The asset qualifier path uses assets to cover the whole loan. The asset depletion path divides usable assets by 60 months to create qualifying income.
- Pledged or borrowed funds are not published as eligible assets on either path. That matters if you plan to borrow against the portfolio and also qualify on it.
The Honest Answer on Who Each One Is For
A margin loan fits a buyer who wants to keep a portfolio invested, borrow against it briefly, and has a clear plan to repay. It is a bridge tool. An asset-based mortgage fits a buyer with large balances and little documented income, such as a retiree, someone who sold a business, or a household living off a portfolio. It is a long-term loan with a repayment schedule.
Many people treat these as rivals. They are not. One is a credit line on your investments. The other is financing on the home itself.
Side-by-Side
The margin column shows published industry norms. The asset-based column shows how these loans are typically structured across Lendmire’s wholesale network, subject to underwriting.
| Factor | Margin Loan | Asset-Based Mortgage |
|---|---|---|
| Review basis | Value and type of pledged securities | Verified assets, credit, the property |
| Documentation | Brokerage account agreement | Seasoned statements, credit, appraisal, title |
| Property types | Not tied to a property; permitted use set by your custodian | Residence or second home; investment on depletion path only |
| Entity vesting | Personal account, generally | Individual borrower, generally |
| Process steps | Brokerage step, no property review | Full mortgage file with property review |
| Reserve expectations | Cushion to meet maintenance calls | None at or below 75% LTV, qualifier path |
| Stress event | Forced sale of holdings possible | No market-driven call; payments due on schedule |
LTV means loan-to-value, the loan as a percentage of the property’s value. Reserves are cash or assets left over after closing.
Key Terms Defined
Margin loan: a loan from your broker, secured by securities in your brokerage account, that is not a mortgage.
Securities-backed line of credit (SBLOC): a credit line secured by a pledged investment account. It is usually a non-purpose loan, meaning you cannot use it to buy securities.
Asset qualifier path: a way to qualify where eligible assets, after the credit percentages, must equal or exceed the entire loan amount.
Asset depletion path: a way to qualify where usable assets divided by 60 months become monthly qualifying income.
Seasoning: how long money has sat in an account before a lender counts it.
When a Margin Loan Is the Better Fit
A margin loan wins when speed of access and flexibility matter more than long-term structure. It also wins when you do not want to sell appreciated holdings. Three buyer profiles tend to fit.
The short-term bridge. Say you are selling a current home and need cash for the next one before the sale closes. A margin loan can cover the gap, and the sale proceeds repay it. The plan has a clear exit date, which is what makes this use defensible.
The portfolio holder with a small gap. Suppose you need a modest slice of the purchase price and the rest comes from savings or sale proceeds. Borrowing a small share of a large portfolio leaves a wide cushion. Under Federal Reserve Regulation T, firms can generally lend up to 50% of the purchase price on initial margin purchases, and borrowing well below that cap is what keeps the cushion wide.
The buyer who wants no mortgage process. A margin draw is a brokerage transaction. No appraisal, no title work, no mortgage underwriting of the property. For a buyer making a cash-style offer, that simplicity is real.
The tradeoffs are just as real. Margin loans are generally interest-only and open-ended. Nothing forces you to pay the balance down, and nothing protects you if the account shrinks. Ask your custodian in writing what the cash can be used for before you pledge anything toward a purchase. Brokers differ on this.
There is one more catch. If the same securities secure a margin loan, they are no longer free assets. A mortgage lender looking at your statements will see the borrowing.
When an Asset-Based Mortgage Is the Better Fit
An asset-based mortgage wins when you want permanent financing, a fixed schedule, and no exposure to market-driven calls. The home is the collateral, and your portfolio stays yours. This is the better tool for most primary residence buyers who are asset-rich and income-light.
Which path fits you depends on how big your assets are compared with the loan.
Asset qualifier path: assets cover the whole loan
On this path, eligible assets after the credit percentages must equal or exceed the entire loan amount. No employment or income is documented. Through select programs, leverage runs up to 80% LTV on a purchase and 75% on a refinance, on a principal residence or second home. Loans go up to $4,000,000, with a 600 minimum credit score, subject to underwriting. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Here is how the balances count on this path:
- Brokerage accounts, CDs, money market and savings count at 100%.
- 401(k) and IRA balances count at 90% under age 59½ and 100% at 59½ or older.
- Accounts combine.
Run the numbers on an $800,000 loan. Say you hold $330,000 in brokerage accounts (100% counts, so $330,000), $300,000 in a 401(k) while under 59½ (90% counts, so $270,000), and $200,000 in savings (100% counts, so $200,000). That totals $800,000 of usable assets, which can qualify on assets alone. The lender’s own calculation governs.
Seasoning is 60 days, with two months of statements for each qualifying account. No reserves are required at or below 75% LTV. Above that, the lender sets them. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Asset depletion path: assets become income
Here your assets turn into monthly income that must carry the housing payment and other debts through the debt-to-income test. That test compares monthly debts with monthly income. Consider $1,500,000 in securities (80% counts, so $1,200,000) plus $300,000 in cash (100% counts, so $300,000). That is $1,500,000 usable, divided by 60 months, or $25,000 of monthly qualifying income.
On this path:
- Loan amounts run $125,000 to $3,500,000.
- Leverage is up to 80% on a purchase or rate-and-term refinance of a principal residence or second home. A cash-out refinance on those properties goes up to 60%.
- Investment property is eligible only on this path, up to 65% on a purchase and 60% on a cash-out.
- Cash accounts and CDs count at 100%. Securities count at 80%, retirement accounts at 70% at any age, and real-estate equity at 60%.
- Qualified assets must be at least the lesser of $1,000,000 or 1.25 times the loan balance, and never below $250,000 liquid when depletion is your only income source.
- Credit follows the lender’s matrix, and a first-time investor needs 700.
- Statements must be at least 120 days old at application, plus the most recent one within 45 days.
Asset-derived income can also supplement documented income up to a 45% debt-to-income ratio. When it does, the minimum-assets rule is waived.
What does not count
Privately held company stock is not eligible on either path. A founder or shareholder’s route is documented liquid assets, such as seasoned proceeds from a sale or buyout. Cryptocurrency, precious metals, collectibles, and pledged or borrowed funds are not published as eligible on either path. The documented route is converting them to a seasoned cash balance in a regulated account, with the source reviewed by the lender. Custodial accounts, escrow accounts, foreign funds, stock options and non-vested restricted stock units are excluded on the depletion path. These loans document your assets in full. Skipping income paperwork does not mean skipping paperwork.
What Happens When the Market Drops?
This is where the two options split hardest. With a margin loan, a falling market can trigger a call for more collateral or cash. If you cannot meet it, your brokerage can sell your holdings, often without asking which ones, at the worst possible prices. Because the collateral is revalued continuously, the risk never switches off while the balance is outstanding.
The closest cousin, the SBLOC, works similarly. A maintenance call on a securities-backed line typically gives two or three days to post collateral or repay. Not much time when your portfolio just fell.
Picture a portfolio that drops 30% in a rough stretch after you closed. On a margin loan, that drop shrinks your borrowing cushion exactly when you least want to sell. On an asset-based mortgage, the home is the collateral, and your payment stays due on schedule. Your portfolio still lost value, and on the depletion path your qualifying figure was set at application. Nothing gets called.
Here is the honest nuance. A mortgage does not remove risk. It swaps market-driven risk for payment-driven risk. A margin loan has no scheduled paydown, so nothing forces discipline. A mortgage amortizes, which means you carry a fixed obligation either way. Neither is gentle if your plan depends on the market behaving.
What the Mortgage Lender Sees
If you borrow on margin for the down payment and then apply for a mortgage, the lender will review your statements. Across our wholesale network, borrowed or pledged funds are generally not treated as eligible assets, because they are not yours free and clear. Lenders in the network differ in how they treat a down payment sourced from borrowing, and published guidance is thin. Raise it with a broker before you draw, not after.
The rule behind this is practical. Under the federal ability-to-repay standard, a mortgage lender must verify the income or assets it relies on using reasonably reliable third-party records. That is why seasoned statements matter so much on the qualifier path and the depletion path. Margin loans and SBLOCs sit outside that mortgage framework entirely.
A practitioner observation from this kind of file: borrowers often shift money between accounts right before applying. That creates seasoning problems. Statements that are stable for two months, or 120 days on the depletion path, make the file cleaner than any last-minute reshuffle.
What If the Purchase Is a Rental?
Rental buyers face a different decision. An asset-based mortgage reaches investment property only on the depletion path, at 65% on a purchase and 60% on a cash-out. Both a margin-funded purchase and an asset-based loan lean on your portfolio.
DSCR loans take a different route. DSCR stands for debt service coverage ratio. These loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. A DSCR file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, which keeps your portfolio out of the qualification. Through select lenders in the network, some programs review coverage below 1.00, with leverage and terms adjusting accordingly. Entity vesting is also possible on DSCR, subject to program terms.
If you are weighing pledged-asset financing against a margin loan, Lendmire has covered how a pledged-asset mortgage compares with a PAL and a margin loan on a purchase versus a cash-out.
A Balanced Verdict
Choose the margin loan if you need a short bridge, have a clear repayment source, and will borrow a small slice of a large portfolio. Keep a cash buffer. Plan for the call, not just the draw.
Choose the asset-based mortgage if this is a long-term home, your balances are large and your documented income is small, and you want a fixed schedule with no market-driven call. Pick the qualifier path when your eligible assets cover the whole loan. Pick the depletion path when assets must become income. Expect the home to be a principal residence or second home on the qualifier path, with investment property reserved for depletion.
Some buyers use both in sequence: a short bridge now, a permanent loan later. That can work. Just remember that the bridge borrowing shows up on your statements.
If you are qualifying on assets rather than income and want to see how the numbers work, Lendmire can help you compare asset-based mortgage options based on your statements, the property, credit profile, leverage, and your goals.

Frequently Asked Questions
Can I use a margin loan for a down payment?
Often yes, if your brokerage allows the cash to be used outside the account, so confirm in writing. The risk is that the loan stays secured by your securities while you also carry a mortgage. If you apply for a mortgage afterward, the lender reviews where the funds came from, and borrowed funds are not published as eligible assets on either path.
Is a margin loan the same as an SBLOC?
No. A margin loan is a purpose loan tied to your brokerage account. An SBLOC is typically a non-purpose line, so you cannot use it to buy securities, and the collateral often sits in a separate pledged account. Both can be called when collateral falls, but the terms and process differ by provider.
Does an asset-based mortgage require income documentation?
Not on the qualifier path, which is reviewed on assets alone. On the depletion path, assets are converted into income and run through the debt-to-income test. Either way, the assets themselves are documented with seasoned statements, and credit is still reviewed.
Can I use retirement accounts?
Yes, in part, through select programs. On the qualifier path, 401(k) and IRA balances count at 90% under age 59½ and 100% at 59½ or older. On the depletion path, retirement accounts count at 70% at any age. Underwriting reviews each file.
What if my portfolio drops before I close?
It depends on the path. On a margin loan, a drop can trigger a call. On an asset-based mortgage, a lower balance can reduce what counts, which can affect whether assets cover the loan or what income they produce. Keep a cushion beyond the minimum.
