That said, borrowing against assets isn't a one-size-fits-all move. Outcomes shift based on the asset type you're pledging, the lender's terms, market swings, and how disciplined you are about repayment. This guide walks through the main borrowing methods, a step-by-step process, the factors that shape your terms, common mistakes, and alternatives worth weighing before you sign anything.
Key Takeaways
- Margin loans, SBLOCs, and HELOCs let you access cash without selling investments or your home
- Each option has different collateral rules, borrowing limits, and risk exposure
- HELOCs suit long-term, home-related needs; margin loans and SBLOCs fit shorter-term investment liquidity
- Success hinges on diversification, borrowing conservatively, and having a repayment plan before you draw funds
How to Borrow Against Your Assets: Step-by-Step
Step 1: Identify Which Assets You Can Use as Collateral
Start by taking inventory. Eligible collateral generally falls into three buckets:
- Brokerage securities - stocks, bonds, mutual funds, ETFs
- Home equity - the difference between your home's value and what you still owe
- Other investment accounts - certain cash equivalents, CDs, or diversified holdings
Lenders also set minimums by product:
- Margin — FINRA requires at least $2,000 in equity to open a new position, with a 25% maintenance baseline on long securities FINRA's margin rules
- SBLOCs — brokerages like Schwab, Fidelity, and Merrill typically want $100,000+ in portfolio value FINRA's SBLOC explainer
- HELOCs — eligibility hinges on appraised home value minus existing liens, plus your credit and income
One catch: concentrated, undiversified holdings can limit how much you're able to borrow, regardless of total portfolio size. A single stock position, even a large one, doesn't carry the same weight as a diversified basket.
Step 2: Choose the Right Borrowing Structure for Your Goal
Match the tool to the timeline and purpose:
- Margin loans - tied directly to buying securities; the purchased securities become collateral
- SBLOCs - non-purpose credit secured by your portfolio; funds can go toward almost anything except buying more securities
- HELOCs - revolving credit secured by home equity, better suited to staged or long-term expenses
If the goal involves your house—renovation, debt consolidation, or a large purchase—a mortgage advisor like ClearPoint Mortgage Advisors can compare a HELOC against a cash-out refinance. Rate structure and repayment terms differ enough that the wrong pick can cost you for years.
Step 3: Apply and Get Underwritten
The application experience varies dramatically by product:
- Margin accounts - typically set up through existing brokerage paperwork, often with minimal additional documentation
- SBLOCs - some lenders skip a credit check entirely, basing the limit mainly on portfolio value. FINRA notes funds may be available within a week of signing FINRA's SBLOC explainer
- HELOCs - require a property appraisal, credit check, and full underwriting review, plus disclosure of APR, payment terms, and closing costs
Before funds release, lenders confirm conditions are met:
- Loan-to-value limits fall within acceptable range
- Maintenance requirements are satisfied
- Documentation, whether income verification or account statements, checks out
Processing timelines differ too. Some SBLOC providers report approvals in as little as one business day. HELOCs need appraisal scheduling and underwriting review, which typically takes weeks rather than days.
A note for self-employed borrowers: tax-return income doesn't always reflect real cash flow. Bank statement programs (12- or 24-month), 1099 programs, and business deposit analysis can offer a fuller financial picture when qualifying for home equity products.
Step 4: Draw Funds and Manage Repayment
Once approved, how you draw and repay depends heavily on the product:
- HELOCs commonly offer a draw period (often around 10 years) followed by a repayment phase of 10 to 20 years, sometimes ending in a balloon payment
- SBLOCs usually charge interest only on what's drawn, and you can repay principal and re-borrow
- Margin loans carry the tightest monitoring, since falling security values can trigger action fast
Watch your collateral value closely. For SBLOCs, a maintenance call typically gives you just two or three days to respond with more collateral or repayment FINRA's SBLOC explainer. Margin calls can move even faster, and firms aren't always required to notify you before selling.
Set a repayment timeline before you borrow, not after. Knowing how you'll pay the balance down protects you from being forced into a sale at the worst possible moment.
Key Factors That Affect Your Borrowing Terms
Your loan amount, cost, and risk profile depend on a handful of variables that shift from borrower to borrower.
Asset Type and Liquidity
Liquid securities generally support higher loan-to-value ratios than real estate or illiquid holdings. Lenders take less risk when an asset is easy to sell, so liquid collateral usually means higher advance rates and faster access to funds.
Loan-to-Value Ratio
This ratio determines how much you can borrow relative to your asset's value. According to FINRA, SBLOC advance rates range from 50% to 95% of portfolio value, depending on the underlying holdings. Higher LTVs increase your exposure to margin calls or collateral demands if values dip.
Interest Rate Structure
Most asset-backed loans use variable rates tied to market benchmarks:
- Margin loans often reference the brokerage's own margin schedule
- SBLOCs typically combine a fixed spread with variable SOFR
- HELOCs commonly track Prime or a Treasury-based index (CMT)
Rising rates mean rising borrowing costs over time, particularly with revolving products where you can't lock in a fixed payment.
Diversification of Collateral
Concentrated holdings—too much weight in a single stock, sector, or asset class—raise the risk of forced selling if values drop. FINRA specifically flags concentration risk as a factor that can amplify losses. Diversified collateral tends to support better borrowing terms and lowers the odds of a sudden collateral call.
Common Mistakes to Avoid
A few avoidable errors can turn flexible asset-backed credit into forced sales or sudden calls:
- Borrowing the maximum available instead of a conservative portion, leaving no cushion for market swings
- Using short-term tools for long-term needs, such as stretching margin loans or SBLOCs across multi-year plans and raising market exposure
- Skipping a backup liquidity plan, so one bad month without secondary cash or a clear repayment timeline can force an unwanted sale
- Ignoring collateral value changes, because a drop in portfolio or home value can trigger a call with little warning
Alternatives to Borrowing Against Your Assets
Sometimes selling outright, or borrowing without collateral, makes more sense than pledging what you own.
Selling Investments Outright
This path fits when you need the funds permanently, or you're worried about market timing risk.
Trade-offs: selling can trigger capital gains taxes, and you lose any future upside on the position. Gains are typically reported on Form 8949 and summarized on Schedule D, with long-term treatment after a one-year holding period.
Cash-Out Refinance
Choose this when you want a fixed-rate, lump-sum loan against your home equity rather than a revolving line.
Trade-offs: closing costs and a reset mortgage term. Cash-out refinances also tend to carry higher rates and payments than a standard rate-and-term refinance. The CFPB flags that gap as a foreclosure-risk factor worth weighing in its mortgage report.
ClearPoint Mortgage Advisors can help borrowers compare a cash-out refinance against a HELOC side by side.
Personal or Unsecured Loans
These fit when you need a smaller amount and would rather not pledge any assets at all.
Trade-offs: rates typically run higher than asset-backed alternatives, since the lender has no collateral to fall back on.
Conclusion
Borrowing against your assets, with a clear plan, lets you preserve your investment strategy and avoid selling off property or portfolio holdings you'd rather keep. The math can work strongly in your favor.
Most of the risk doesn't come from the products themselves. It comes from:
- Over-borrowing beyond what your cash flow can support
- Holding concentrated collateral
- Skipping a repayment plan before funds ever hit your account
Before using home equity or investments as collateral, talk to a financial or mortgage advisor. If your plans involve your home, ClearPoint Mortgage Advisors can help you weigh a HELOC against a cash-out refinance and figure out which structure fits your goals.
Frequently Asked Questions
What is a loan against equity?
It's a loan secured by an asset—such as home equity or investment holdings—that lets you access cash without selling that asset.
Can I take a loan against equity?
Most homeowners and investors with sufficient equity or portfolio value can qualify, subject to lender requirements like credit history, income verification, and loan-to-value limits.
How much equity do you need to borrow against your house?
Requirements vary by lender, but many require you to retain 15-20% equity after borrowing. Some lenders allow borrowing up to 85% of your home's value minus the outstanding balance.
What's the difference between a HELOC and a margin loan?
A HELOC is secured by home equity and structured for longer-term borrowing, often with a 10-year draw period. A margin loan is secured by securities and typically serves shorter-term, trading-related needs.
Is interest on asset-backed loans tax-deductible?
It depends on how you use the funds, not what secures the loan. HELOC interest is only deductible if proceeds improve the home; margin interest may qualify as investment interest if used to buy taxable securities. Consult a tax professional.
What happens if my collateral loses value?
Lenders may issue a margin call or collateral demand, requiring you to add funds, pledge more securities, or repay part of the balance. Response windows can be as short as two or three days, and failure to act can lead to forced asset sales.
