A HELOC can be a smart, low-cost source of funds — or a trap, depending on how you use it. Because it's secured by your home, rates are far lower than credit cards, and you only pay interest on what you draw. That makes it well suited to value-adding renovations, consolidating high-interest debt, or a standby safety net.
The risks
The rate is usually variable, so payments can rise. The interest-only draw period can lull borrowers into overspending, then the payment jumps when repayment starts (see the draw vs. repayment period). And your home is the collateral — miss payments and you risk foreclosure.
The bottom line
A HELOC is a good idea for disciplined borrowers using it on things that build wealth or cut costs, and a poor one for funding lifestyle spending. Estimate the payment first with the HELOC calculator.
