Should you use a HELOC to invest in stocks?

It's borrowing against your home to buy something that can fall in value.

The risks

• Markets can fall while the variable HELOC rate rises.
• A lender can freeze the line in a downturn.
• Interest used to buy investments is generally not deductible as mortgage interest.

Break-even math

Markets have exceeded that over long periods, and fallen far short over others. A HELOC payment is due every month either way.

If you're set on it

• Keep the amount small relative to your income and savings.
• Lock the balance at a fixed rate.
• Have cash to cover payments for a year without selling.

Example: $100,000 borrowed to invest

At 7.75% APR, interest on $100,000 is about $7,750 a year. To break even, the portfolio must earn more than that after taxes, every year, on average. In a good year with a 15% return, you're ahead about $7,000 before taxes. In a year like 2022, when broad stock indexes fell around 18%–20%, you'd be down roughly $20,000 in value and still owe $7,750 in interest, with your home securing the debt.

Investment interest

Interest on money borrowed to buy taxable investments may be deductible as investment interest expense, up to your net investment income, if you itemize. It follows different rules from mortgage interest. Ask a tax advisor before counting on it.

Why the timing risk is worse with borrowed money

Markets can stay down for years. If you need the money back during a downturn, or the HELOC rate rises, you may have to sell at a loss to make payments. Investing borrowed money removes your ability to wait out a bad stretch.

Safer ways to invest more

• Pay off high-interest debt first; it's a guaranteed return.
• Max out tax-advantaged accounts from cash flow.
• If you're set on leverage, use a small amount you could repay from savings, with a fixed-rate lock.

If you still want to do it

• Limit the amount to what you could repay from savings.
• Lock a fixed rate if available.
• Diversify; avoid single stocks.
• Have a plan for a 30% market drop.

The math over ten years

Borrowing $100,000 at 7.75% for ten years costs $77,500 in interest if paid interest-only. A portfolio would need to average a bit above 7.75% a year after taxes just to break even, and the ride matters: a 30% drop in year two could force selling to meet payments.

Also asked

Can you use a HELOC to buy real estate instead of stocks?

Buying a rental is a more common use of a HELOC than investing in stocks, because a rental produces income to cover the interest. Real estate carries its own risks, though. Buying a rental with a HELOC.

Is a margin loan safer than a HELOC?

Not necessarily. A margin loan doesn't put your home at risk the way a HELOC does, but margin calls can force you to sell in a downturn. Both add risk to investing.

When does investing with a HELOC make sense?

Rarely. Investing with a HELOC is most defensible when the amount is small relative to your savings, the rate is locked, and you could repay the balance from cash at any time.

Should you use a HELOC to buy cryptocurrency?

Usually not. Using a HELOC for cryptocurrency adds even more risk than stocks because of extreme price swings, and a large drop could leave you owing far more than the investment is worth.
