Why HELOC Rates Differ From Mortgage Rates
Why HELOC Rates Differ From Mortgage Rates: what to know and how to act in 2026.
What to know
HELOC rates run higher than first-mortgage rates because the line sits in second-lien position and floats with Prime. A cash-out refinance at first-lien pricing (about 6.5-7.5%) is usually cheaper per dollar than an 8-10% HELOC. The HELOC wins on flexibility and far lower upfront cost.
What affects your rate
- Your credit score and combined loan-to-value
- HELOC (variable, Prime + margin) vs home equity loan (fixed)
- Lien position and occupancy (primary vs rental)
- The Prime rate and Fed policy — and lender margins, so compare quotes
