A HELOC can be a good idea if used for home improvement projects that increase the value of your home. Because a HELOC lets you take out what you need when you need it, it’s best for ongoing projects or expenses.
A HELOC is not a good idea if you don't have a steady income or a financial plan to pay off the loan. Since you use your home as collateral, if you fail to make the payments in full and on time, you risk losing your home.
