Why California Homeowners Choose HELOCs

A stand-alone HELOC acts as a second lien behind your existing first mortgage. If your first mortgage has a fixed rate of 2.75% to 3.50%, taking a HELOC lets you tap equity for renovations, ADU construction, or emergencies without resetting your first mortgage rate.

Frequently Asked Questions: California HELOCs

Essential facts on variable rates, draw periods, and California combined loan-to-value limits.

CLTV is the sum of your first mortgage balance plus your desired HELOC credit limit divided by your home’s appraised value.

In California, most lenders cap CLTV at 80% to 85% for primary single-family residences. Higher CLTV programs up to 90% may be available for borrowers with credit scores of 740+.
