Frequently asked questions

Is a HELOC the same as a home equity loan?

No. A HELOC is a revolving line you can borrow from and repay, and it usually has a variable rate. A home equity loan pays out one lump sum at a fixed rate.

Why is the payment so much higher after the draw period?

During the draw period you pay mostly interest, so the balance does not fall. Repayment spreads the balance over fewer years, which raises each payment.

Can the rate change?

Yes, most HELOCs have a variable rate tied to a market index. Ask how often it can change and how far it can move before you borrow.

What happens if I cannot make the payment?

Because the loan is secured by your home, falling behind can lead to serious consequences. Talk to the lender early if you expect trouble.

Are there costs to open a HELOC?

Some lenders charge an appraisal or closing fee, and some charge an annual fee. Check the terms before you open the line.
