HELOC vs. Cash-Out Refinance in California

I’m Michael DiVita — DRE #01372066 | NMLS #241655, DiVita Home Finance (DRE #01818285 | NMLS #323700), Tiburon, CA. I’ve been in California mortgage lending since 2000 and founded DiVita Home Finance in 2007. I’m known as a creative mortgage broker: when a bank says no, I find the lender and the loan structure that can say yes. Call (800) 239-1103.

Many California homeowners locked in first-mortgage rates between 2.5% and 3.5% in 2020–2022. They now have a lot of equity and a real reason to use it — an ADU, a remodel, tuition, a rental down payment. The question I get most: should I do a cash-out refinance, or add a HELOC or home equity loan?

Short answer: if your current rate is well below today’s rates, a second lien usually costs less, because you pay the higher rate only on the new money. But “usually” isn’t “always,” so here’s how to run the numbers.

How Each Option Works

Cash-Out Refinance

Your lender pays off your existing first mortgage and gives you a new, larger loan. You receive the difference in cash. The new rate applies to the entire balance — the old debt and the new cash — and the payoff clock usually restarts at 30 years.

HELOC (Home Equity Line of Credit)

A revolving line recorded behind your first mortgage. You draw what you need during the draw period (commonly 10 years), often paying interest only, then repay principal and interest over the repayment period. The rate is usually variable — Prime plus a margin. Your first mortgage is untouched.

Home Equity Loan (HELOAN)

Also a second lien, but a fixed-rate lump sum with a fixed payment, commonly over 10–30 years. Your first mortgage is untouched.

The Numbers: A California Example

A homeowner with a $900,000 home borrowed $350,000 at 2.75% (30-year fixed) in 2021. About five years later the balance is roughly $309,700 and the payment is $1,429 principal and interest. They need $200,000 for a remodel and an ADU. Rates below are illustrative, for comparison only:

What the table shows:

• Interest cost is the real difference. Both second-lien options cost roughly $7,000–$9,600 less interest in the first year, because the 2.75% rate keeps working on the $309,700.
• Monthly payments can look similar. The home equity loan’s payment is close to the cash-out payment only because it’s paid off in 20 years instead of restarting a 30-year clock.
• The HELOC payment isn’t fixed. It moves with Prime, and when the draw period ends, principal repayment begins — on $200,000 at 7.5% over 20 years that’s about $1,611 a month.

Your numbers will differ with your balance, rate, credit and equity. I’ll run all three side by side with live pricing.

When a Cash-Out Refinance Still Makes Sense

• Your current rate is already close to (or above) today’s rates.
• You want one fixed payment and a single loan.
• You’re consolidating a large amount of high-interest debt and want it all on a long fixed term.
• You need more than second-lien programs will lend.
• You want to remove someone from the loan or change the loan structure anyway.

Side-by-Side Comparison

California-Specific Considerations

Prop 13

Neither a HELOC nor a cash-out refinance is a change in ownership, so neither triggers a Prop 13 reassessment of your property taxes. See Prop 13 explained.

Anti-Deficiency Protection

California’s anti-deficiency statute (Code of Civil Procedure §580b) protects purchase-money loans on owner-occupied homes of up to four units, and since 2013 it also covers refinances of those loans — but not any new principal advanced beyond what was used to pay off the purchase loan. In practice, cash taken out in a refinance, and most HELOCs, don’t get purchase-money protection. This matters most at high loan-to-values. Talk to a real estate attorney about your specific exposure.

Tax Treatment

Federally, interest on home equity debt is generally deductible only when the money is used to buy, build or substantially improve the home that secures it. California didn’t adopt that limit and still allows interest on up to $100,000 of home equity debt. For a cash-out refinance, the part of the new loan that replaced your old mortgage is treated as acquisition debt. Check with your tax advisor.

Frequently Asked Questions

Can I keep my low mortgage rate and still access my equity?

Yes. A HELOC or home equity loan is a separate second lien. Your first mortgage’s rate, balance, payment and servicer stay exactly the same.

Is a HELOC rate higher than a cash-out refinance rate?

Usually, yes. But the HELOC rate applies only to what you borrow, while a cash-out refinance applies the new rate to your entire balance. If your existing rate is well below market, the second lien usually costs less in total interest.

Can I get a HELOC if my first mortgage is with a different lender?

Yes. The second-lien lender doesn’t need to be your first-mortgage lender or servicer, and it can’t change your first mortgage’s terms.

What if rates drop — should I do a cash-out refinance then?

Maybe. The smaller the gap between your current rate and market rates, the better a cash-out refinance looks. A HELOC or home equity loan now doesn’t lock you out: you can refinance the second lien later, or combine both loans into a new first mortgage if the math works.

Does a HELOC or cash-out refinance affect my Prop 13 taxes?

No. Neither is a change of ownership, so your assessed value doesn’t reset.
