Quick answer

A home equity loan usually provides a fixed lump sum repaid in scheduled installments. A HELOC is an open-end line that can be borrowed, repaid and borrowed again during the draw period, often with a variable rate. Both are commonly second mortgages and can lead to foreclosure if the debt is not repaid.

How the borrowing structures differ

A home equity loan provides the approved amount at closing. This can suit a defined project with a known budget. The payment schedule begins on the full balance, even if the borrower does not immediately spend every dollar.

A HELOC provides a maximum credit limit rather than one automatic lump sum. Interest generally applies to the amount drawn, not the unused line. Access and repayment rules change when the draw period ends.

Rate and payment risk

Home equity loans commonly use a fixed interest rate and predictable payment. HELOCs often use a variable annual percentage rate tied to an index plus a margin, so payments can rise even without additional borrowing.

Some HELOCs allow lower payments during the draw period, including interest-only structures. The later repayment period can produce a significant payment increase. Ask for examples showing payments at different rates and balances.

Fees and closing costs to compare

Either product can include application, appraisal, origination, annual, inactivity, early-closure or third-party fees. A low advertised rate does not show the full cost. Review the APR, fee schedule and conditions for waiving fees.

Ask whether a HELOC has a minimum initial draw, minimum transaction amount or annual fee. For a home equity loan, compare the total financed amount, term and prepayment provisions.

When each structure may fit

A lump-sum loan can be easier to budget for a fixed project or one-time obligation. A HELOC can be more flexible for phased repairs or uncertain timing, but it creates more opportunity to reborrow and carry variable-rate debt.

Do not choose solely based on the initial monthly payment. Consider the maximum rate, repayment-period payment, total interest if the balance remains outstanding and whether the home can still support other priorities.

Questions to ask before using home equity

Using home equity converts property value into secured debt. Confirm how the new lien affects a future sale or refinance, whether the lender can freeze or reduce a line, and what happens at the end of the draw period.

Compare alternatives that do not place the home at risk. For necessary repairs, also consider project timing, emergency reserves and whether a smaller scope can be funded from savings over time.

Frequently asked questions

Is a HELOC a second mortgage?

A HELOC is commonly a junior lien or second mortgage when a first mortgage already exists.

Can a HELOC payment increase?

Yes. Variable rates, additional draws and the transition from draw to repayment can increase the required payment.

Does unused HELOC credit cost interest?

Interest generally applies to the outstanding balance, but annual or other account fees may still apply depending on the agreement.
