HELOC pros and cons

A HELOC is one of the cheapest ways to borrow. It's also secured by the place you live. Both are true.

Pros

• Low rate. About 8.00%–9.75% APR for 720–759 credit today, versus 20%+ on cards.
• Flexibility. Draw, repay and draw again for about 10 years.
• Interest only on what you use. An unused line usually costs little or nothing.
• Keeps your first mortgage. No need to refinance a low rate.
• Possible tax deduction when used to improve the home.

Cons

• Your home is collateral. Missed payments can lead to foreclosure.
• Variable rate. Payments rise when prime rises.
• Payment shock. Interest-only payments end; see how much they jump.
• Easy to overspend. A line feels like money you have.
• Lenders can freeze it if home values drop sharply. When that happens.

Who should skip it

People with unstable income, those who'd borrow to the maximum, and anyone using it to cover a monthly shortfall rather than a one-time cost.

Versus the alternatives

Against credit cards and personal loans, a HELOC usually wins on cost. Against a cash-out refinance, it wins when your first-mortgage rate is low. Against a home equity loan, it wins when spending is spread out. HELOC vs. cash-out · HELOC vs. personal loan.

Before deciding, read when a HELOC is a bad idea.

The pros in dollars

• Rate. At 7.75% APR, $30,000 costs about $194 a month in interest. On a card at 24.9%, the same balance costs about $623 a month in interest alone.
• Flexibility. Draw only what you need, when you need it, and pay interest only on that.
• Keeping your first mortgage. If your mortgage rate is low, a HELOC avoids refinancing it at today's rates.
• Possible tax deduction when the money improves the home and you itemize.

The cons in dollars

• Rate risk. A 2-point rise on a $60,000 balance adds about $100 a month in interest.
• Payment shock at the end of the draw period: often 25%–90% higher, depending on the repayment term. See the math.
• Fees: annual fees, early-closure fees and appraisal costs on some lines.
• Your home is collateral. Default can lead to foreclosure.

A five-question gut check

1. Is this for a one-time cost, not monthly spending?
2. Could you afford the payment if the rate rose 2 points?
3. Do you have a plan to pay it off, with a date?
4. Will you keep at least 15%–20% equity in the home?
5. Is the HELOC clearly cheaper than the alternative you'd otherwise use?

Five yeses: a HELOC is likely a good fit. Any no: look harder at the alternatives.

Example: the same HELOC, two outcomes

Two neighbors each open $80,000 lines at 7.75% APR. One uses $60,000 for a kitchen, pays $700 a month, and is debt-free in about ten years. The other draws $60,000 over three years for vacations and car repairs, pays interest only, and at the end of the draw period owes $60,000 with a payment that jumps to about $493 a month for 20 years. Same product, same rate: the plan made the difference.

Compared with alternatives

Against a cash-out refinance, a HELOC keeps a low first-mortgage rate. Against a personal loan, it's usually cheaper but slower and secured by your home. Against a credit card, it's far cheaper but lacks purchase protection.

Checklist

• Payoff date set.

Also asked

Is a HELOC better than a personal loan?

Usually, for larger amounts or longer payoffs: a HELOC costs less than a personal loan because its rate is lower. For small amounts, urgent needs, or if you don't want your home involved, a personal loan's speed and simplicity can win.
