Usually not. Most home-equity lines of credit have variable rates built from an index plus a margin. The rate and payment can change even when no additional money is borrowed. Some plans allow a portion of the balance to be converted to a fixed rate, often with separate terms.
What matters most
- Ask which index is used, the margin, adjustment frequency, rate floor, and maximum rate.
- An introductory rate may expire and move to the regular variable-rate formula.
- Draw-period payments can be lower than repayment-period payments, especially when early payments are interest-only.
How to use this answer
Review the highest possible payment you could reasonably face, not only the opening rate. Ask whether fixed conversions are available, how they are priced, and whether each conversion has fees or minimum amounts. Leave room in the budget for rate and repayment-period changes.
A simple example
A HELOC begins with a promotional rate and an interest-only payment. When the promotion ends or the index rises, the payment can increase. It may rise again when the line enters repayment and principal must be paid on a fixed schedule.
What to review before you decide
- Confirm the loan program, occupancy, property type, and timeline.
- Review the complete payment and cash-to-close estimate, not one number in isolation.
- Verify current program rules and lender requirements before moving money or signing a contract.
Frequently asked questions
Questions readers often ask next.
Can my payment change if I stop borrowing?
Yes. A variable rate can change, and the plan may later move from the draw period to the repayment period.
Is a home-equity loan fixed?
Many home-equity loans offer a fixed rate and lump-sum proceeds, but terms vary by lender.
