The Quick Read: These three tools borrow against your investments in different ways. A pledged-asset mortgage puts securities behind the home loan itself, a pledged-asset line (PAL) is a separate credit line secured by your portfolio, and a margin loan is borrowing inside the brokerage account. The right one depends on whether you are buying a home or pulling cash from one you already own, and on how much of a market drop your household can absorb.
The honest answer, up front: a pledged-asset mortgage is for buyers who want to keep a portfolio invested instead of cashing out for a down payment. A PAL is for people who want a flexible, separate line they can draw on. Margin is for short-term, tightly watched borrowing. None of them is free money. All three put your investments at risk while your mortgage payment keeps coming due.
One note on terms. Lenders use “pledged-asset” loosely, and “PAL,” “securities-backed line of credit” (SBLOC) and “portfolio line” often mean the same thing. Definitions are below, because the labels change from one lender to the next.
Key Terms Defined
Pledged-asset mortgage: A home loan where investments are pledged as extra collateral, usually in place of some or all of a cash down payment.
Pledged-asset line (PAL): A separate credit line secured by a brokerage portfolio. It is also called a securities-backed line of credit, or SBLOC.
Margin loan: Borrowing from your brokerage firm against the securities held in that same account.
Collateral call: A demand to add cash or securities, or to pay down the loan, after the pledged assets lose value.
Limited cash-out refinance: A refinance that pays off the existing first mortgage and closing costs, with only incidental cash back. Lendmire’s wholesale programs also call this a rate-and-term refinance.
Cash-out refinance: A refinance where you take a larger loan than you owe and keep the difference.
Side-by-Side
| Factor | Pledged-Asset Mortgage | PAL / SBLOC | Margin Loan |
|---|---|---|---|
| What secures it | Home plus pledged securities | Securities portfolio | Securities in the account |
| Is it a mortgage? | Yes, one loan | No, a separate line | No, an account feature |
| Home loan credit review | Full file review | Home loan reviewed separately | Home loan reviewed separately |
| Mortgage insurance | May be reduced or avoided, per lender | Depends on the home loan itself | Depends on the home loan itself |
| Where it lives | Mortgage lender | Bank or brokerage lender | Brokerage account |
| Collateral calls | Possible, per loan terms | Possible, usually with a cure period | Possible, firm may sell without notice |
| Retirement accounts | Varies by lender | Often not eligible | Usually not eligible |
| Documentation | Mortgage plus asset statements | Portfolio statements | Brokerage statements |
Treat the table as general patterns. Terms differ by lender and program, and every figure is subject to lender guidelines and full file review.
How Each One Actually Works on a Purchase
Start with the mortgage side, because that is where most of the confusion lives.
Across the wholesale programs we place files with, standard conventional purchases run to 95% LTV on a principal residence (5% down), or 97% (3% down) with a fixed rate when a borrower is a first-time buyer. LTV, or loan-to-value, is the loan balance divided by the home’s value. Mortgage insurance applies above 80% LTV. It can be cancelled at the borrower’s request at 80% of the original value, and the servicer must end it automatically at 78%.
That is the baseline any pledged-asset structure gets compared to. The pitch is simple: pledge securities instead of selling them, and you may reduce the cash you bring or the mortgage insurance you carry.
Here is the catch. Fannie Mae’s guide says personal property may not be included as additional security on a one-unit mortgage unless Fannie Mae specifies otherwise. That looks like a problem for a true pledged-asset mortgage sold to Fannie Mae on a single-family home. Read it as an interpretation, not a ruling on the product. Whether a given pledged-asset program works depends on the lender and where the loan is sold. Ask before you assume.
The PAL route sidesteps that rule. Fannie Mae accepts borrowed funds secured by an asset as a source of down payment, closing costs and reserves. Its stated reason is that the funds represent a return of your own equity. Savings, CDs, stocks, bonds and 401(k) accounts all appear on its eligible list. The mortgage lender then has to do four things:
- Document the terms of the secured loan.
- Confirm the party lending to you is not part of the sale.
- Show the funds actually reached you.
- Count the payment as debt, with an exception when financial assets secure the loan.
If the same assets also count toward reserves, their value is reduced by the amount borrowed plus fees. So a pledged portfolio does not count twice. Many buyers miss this, and it shrinks the reserves the lender sees.
Margin works the same way on the purchase side, with a different risk profile. It is a live loan inside the account. The firm can raise its own maintenance requirement without advance written notice, and you cannot choose which securities get sold to meet a call.
When a Pledged-Asset Mortgage Is the Better Fit
A pledged-asset mortgage fits when the purchase is the main goal and the portfolio is the down payment.
Picture a buyer with a large, diversified brokerage account and a sizable unrealized gain. Selling would trigger a tax bill. Pledging avoids the sale. The buyer gets one loan, one lender and one set of terms, instead of a mortgage plus a second facility.
It also fits retirees whose income looks thin on paper but whose assets are strong. Lenders can weigh assets in ways that pure income-based approvals do not, though the automated finding and the file review still decide.
Other points in its favor:
- One closing, one payment schedule and one lender to deal with.
- Possible relief from mortgage insurance above 80% LTV, depending on how the lender structures it.
- Investments stay invested and keep working while pledged. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
The costs are real. Pledged holdings can face trading limits. The lender can demand more collateral or sell if values fall. And availability is narrow, since not every wholesale program offers the structure. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
When a PAL Is the Better Fit
A PAL is the better fit when you want flexibility and a clean separation from the mortgage.
It suits a buyer who needs the down payment now but plans to repay from a known source, such as the sale of another home. It also suits someone who wants the home loan to stay standard, with no pledged-asset overlay. The mortgage lender treats the line as secured borrowing under the Fannie Mae framework above. The payment generally counts as debt unless financial assets secure it.
The SEC and FINRA investor alert on these lines is worth reading before you sign. It notes the interest on an SBLOC may change every day, so your carrying cost is not fixed even if the mortgage is. It also warns that market volatility can magnify losses. FINRA adds unintended tax consequences and possible forced sales to the list.
Some programs restrict how proceeds can be used. At least one major brokerage calls its line “non-purpose,” meaning proceeds cannot buy securities. That is one lender’s rule, not a universal one. Read the terms for yours.
When Margin Is the Better Fit
Margin is the narrowest tool, and for a home it earns its place only in short windows.
A margin loan is fast to open because it already sits inside an account you own. That makes it useful for a brief bridge, such as covering a closing gap while a sale settles. It is not built to be a long-term source of home funding.
Why the caution? Margin risk is immediate. FINRA’s margin disclosure says firms may try to notify you of a call but are not required to. Several common beliefs are wrong:
- “The firm must warn me before selling.” It need not contact you, and it can sell even after setting a deadline.
- “I can choose what gets sold.” You are not entitled to choose.
- “My loss is capped at what I put in.” FINRA’s disclosure says you can lose more than you deposit.
For a house, those risks sit on top of a mortgage that keeps billing you. This one is a genuine toss-up for short, disciplined bridging, and a poor fit for anything open-ended.
Purchase vs. Cash-Out: Where the Rules Change
Here is where most comparisons stop, and where the refinance rules matter most.
On a purchase, you are buying and borrowing against assets to fund the deal. On a cash-out refinance, you already own the home. The new mortgage is larger than the old one and you keep the difference. The leverage and seasoning are different.
Across the wholesale programs we place files with, conventional cash-out refinances reach 80% LTV on a one-unit principal residence. Two- to four-unit principal residences and second homes go to 75%. Two seasoning tests apply. The first mortgage being paid off must be at least 12 months old, counted note date to note date. A borrower must also be on title for six months. Fannie Mae’s cash-out guidance names delayed financing as an exception, and inheritance and legal-award exceptions exist as well. Freddie Mac’s cash-out page also calls for a new appraisal and inspection report, plus a credit fee tied to score and LTV. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
A narrow wholesale lane reaches 89.99% LTV with no mortgage insurance. It needs a 680 score, a 50% ratio, a thirty-year fixed rate, a primary residence, a conforming balance and its own six months of seasoning. In Texas, a homestead cash-out is capped by the state constitution, so that lane is not written there. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Now bring in the tools.
Pledged-asset mortgage on a cash-out. This is the hardest combination. Cash-out guidelines focus on equity in the home, and a pledged-asset overlay may not be offered. Availability varies, so ask whether the program exists on a refinance at all.
PAL on a cash-out. A PAL can work as a separate source of liquidity instead of a refinance, and it leaves your existing mortgage untouched. The trap comes later. Fannie Mae says only purchase-money subordinate liens may be paid off in a limited cash-out. A securities line or other non-purchase-money loan used for something else does not qualify. Paying one off through the refinance makes it a cash-out. The cash-back cap on a limited cash-out is now the greater of 1% of the new balance or $2,000. Small cash back does not make a loan limited cash-out. What gets paid off decides it.
Margin on a cash-out. Same rule. A margin balance is not a purchase-money lien, so rolling it into a refinance converts the deal to cash-out. It also means the home absorbs debt that began as brokerage borrowing.
Streamlines are not an escape hatch. The FHA Streamline and the VA IRRRL are rate-reduction tools for existing government loans. The VA describes the IRRRL as a VA-to-VA loan, so it cannot pull out equity or clear a portfolio line.
A Stress-Test Without Dollar Figures
Picture a buyer who pledges a large share of a stock-heavy portfolio to cover the down payment, using a PAL. The portfolio then drops sharply.
- Under a PAL, the lender may issue a collateral call. You typically get a short deadline to add collateral or pay down the line. Miss it, and the lender can sell.
- Under margin, the firm may sell without notice, and you do not pick which securities go.
- Under a pledged-asset mortgage, the lender can demand more collateral or exercise its right to sell, per the loan terms.
In all three cases, the mortgage payment continues. A forced sale also reaches past the brokerage account. Reserves shrink, debt-to-income can change, and refinance eligibility can shift. The right cushion is the one that survives a bad year without a forced sale. Leave room.
Underwriting: What the Lender Looks At
Mortgage lenders look at the whole picture. Conventional wholesale programs start at a 620 decision score, and the automated finding governs most files, with a total ratio ceiling of 50%. Manually underwritten loans use 36% or 45%, with reserve and score factors from the Eligibility Matrix.
Federal ability-to-repay rules also require a good-faith look at whether you can repay. One factor on that list is the payment on any simultaneous loan, so a second lien or concurrent borrowing used at closing gets counted. A PAL draw does not hide from underwriting.
Automated underwriting also reviews liquid assets you list. It can exclude assets if you qualify without them. And the lender needs to verify ownership of securities. Expect to provide statements.
Which One Fits Which Borrower?
- Buyer with a big portfolio and a large unrealized gain, wanting a low cash down payment: a pledged-asset mortgage, if a program offers it.
- Buyer with a pending home sale: a PAL as a bridge, with a clear repayment source.
- Retiree with strong assets and modest income: compare the pledged-asset mortgage with a conventional loan that weighs assets. Do not borrow more than the income can carry.
- Homeowner wanting cash from the home: compare cash-out refinance programs against leaving the mortgage alone and using a PAL. Lendmire’s cash-out refinance programs page shows what each reaches.
- Anyone who cannot stomach a forced sale: neither margin nor a heavily drawn PAL.

Questions to Ask Before You Commit
1. Is the structure one loan or two, and who holds each?
2. Can the pledge be released, and when?
3. What triggers a call, and how long is the cure window?
4. Can I still trade the pledged holdings?
5. Does the payment count in my debt-to-income, and do the pledged assets count toward reserves?
6. Can proceeds be used for a home, and are retirement accounts eligible?
7. How does the exit work, such as refinancing into a standard mortgage?
The Verdict
If you want one loan, are buying a home, and can find a program that offers it, a pledged-asset mortgage is the cleanest way to keep your portfolio invested. If you want flexibility, or the pledged-asset overlay is not available, a PAL gives you a separate line with a known purpose and a repayment plan. Margin belongs to short, disciplined bridging.
On a cash-out, the picture flips. The equity rules and seasoning drive the answer, and any portfolio loan rolled into the refinance turns it into a full cash-out. Compare the programs, ask the lender the questions above, and size the borrowing for the bad year, not the good one.
If you are weighing a cash-out refinance against keeping the loan you have, Lendmire can help you compare the programs and the equity each one reaches.
Frequently Asked Questions
Is a PAL the same as a pledged-asset mortgage?
No. A PAL is a separate credit line secured by a portfolio, while a pledged-asset mortgage is a single home loan with securities as extra collateral. Lenders mix the labels, so confirm whether you are getting one loan or two.
Can I use a PAL for a down payment?
Often yes. Fannie Mae’s guide treats borrowed funds secured by an asset as an acceptable source of down payment, closing costs and reserves. The lender must document the loan, confirm the provider is not part of the sale, and count the payment as debt unless financial assets secure it.
Do pledged assets still count as reserves?
Only partly. If the same assets also count toward reserves, the lender reduces their value by the amount borrowed plus fees. Count on fewer reserves than your statement shows.
Can I pay off a securities line in a limited cash-out refinance?
Generally not. Only purchase-money subordinate liens may be paid off in a limited cash-out under Fannie Mae’s definitions. Paying off a non-purchase-money line makes the transaction a cash-out refinance, with its own leverage and seasoning rules.
Is the interest on these loans deductible?
It depends on your facts and how the proceeds are used.
