FAQ

Frequently asked questions

What happens when the draw period ends?

You typically move into a repayment period where the balance amortizes over a set number of years, raising your monthly payment.

Are HELOC rates fixed or variable?

Most HELOCs carry a variable rate tied to a benchmark index, so payments can change over time.

Can I keep borrowing during the draw period?

Yes, up to your credit limit, similar to a credit card, which is what makes budgeting for future payments tricky.
