Paying for your retrofit

Three common ways. Compare the total you will repay, not the monthly payment.

Home equity line of creditBorrow against what your home is worth. Rates are usually lower, but your home secures the loan, and approval takes a few weeks.
Personal loanNo collateral and a fast answer. Rates are usually higher and you repay sooner.
Contractor financingMany contractors offer a plan through a lender. Get the rate, fees and total cost in writing, then compare it with your bank.

Earthquake Brace + Bolt. A California program gives grants of up to $3,000 toward bolting and bracing a wood-frame house on a raised foundation built before 1980, in eligible ZIP codes. Registration opens for set periods each year. Check if your house qualifies
