About HELOC Rates

HELOC rates are variable and tied to the prime rate. Current prime rate: 7.50% (Federal Reserve, May 2026). Prime + typical spread of 0.5% = 8.0% estimated HELOC rate.

Rates can change when the Federal Reserve adjusts the federal funds rate. Your actual rate will depend on your credit score, lender, and loan-to-value ratio.

Important: HELOCs use your home as collateral. Missing payments could result in foreclosure. Only borrow what you can confidently repay.

Frequently Asked Questions

A HELOC (Home Equity Line of Credit) is a revolving line of credit secured by your home equity. Think of it like a credit card backed by your home. During the draw period (typically 5–10 years), you can borrow up to your credit limit, make interest-only payments, repay, and borrow again. After the draw period, you enter the repayment period (10–20 years) where you make principal and interest payments on the outstanding balance until it is paid off.

A home equity loan provides a lump sum at a fixed interest rate with fixed monthly payments — essentially a second mortgage. A HELOC is a flexible revolving credit line with a variable rate. Home equity loans offer payment predictability; HELOCs offer flexibility to draw funds as needed. For ongoing projects like home renovations happening over time, a HELOC is often more practical. For a single known expense, a home equity loan may be better.

As of May 2026, HELOC rates are typically in the 8% to 9% range, tied to the prime rate of 7.50%. HELOCs are priced at prime plus a lender margin (typically 0.5% to 1.5%). Your rate depends on your credit score, combined loan-to-value (CLTV) ratio, and your lender. Rates fluctuate when the Federal Reserve changes the federal funds rate, meaning your HELOC payment can increase or decrease over time.

Under current IRS rules (post-2017 Tax Cuts and Jobs Act), HELOC interest is deductible only if you use the borrowed funds to "buy, build, or substantially improve" the home that secures the loan. Using HELOC funds for debt consolidation, education, vacations, or other purposes makes the interest non-deductible. Always consult a qualified tax professional to determine deductibility in your specific situation.

Key risks include: (1) Foreclosure risk — your home is collateral, so missed payments can lead to losing your home. (2) Variable rate risk — if interest rates rise sharply, your payments increase. (3) Payment shock — when the draw period ends and the repayment period begins, payments can jump significantly. (4) Overborrowing — easy access to credit can lead to taking on more debt than is prudent. (5) Home value decline — if your home's value drops, you could end up underwater on your combined loans.
