San Diego homeowners are sitting on record levels of home equity. The median home value in San Diego County has climbed past $900,000, and many homeowners who purchased before 2022 have seen their equity grow by $200,000 or more. A HELOC lets you access that equity without touching your existing mortgage rate — which matters when your first mortgage is locked in at 3% or 4%.
What Is a HELOC?
A Home Equity Line of Credit (HELOC) is a revolving credit line secured by your home. Think of it like a credit card backed by your property. You get approved for a maximum credit limit based on your home's value and what you owe, then draw funds as needed during the draw period — typically 5 to 10 years.
During the draw period, most HELOCs require interest-only payments on the balance you have outstanding. You can draw, repay, and draw again as many times as you want. Once the draw period ends, you enter the repayment period (10 to 20 years) where you pay principal and interest to pay off the remaining balance.
HELOC = Revolving Credit Secured by Your Home
Only pay interest on what you actually draw — not the full credit limit
How Much Can I Borrow with a San Diego HELOC?
Your HELOC borrowing limit is based on your home's current value and your existing mortgage balance. Most lenders allow a combined loan-to-value (CLTV) of 85% to 90%. Some programs go to 95% CLTV for borrowers with excellent credit.
San Diego HELOC Example
With San Diego's strong appreciation, many homeowners qualify for $100,000 to $400,000 or more in HELOC funds. Common uses include home renovations, debt consolidation, investment property down payments, tuition, or maintaining a reserve for opportunities.
HELOC vs. Cash-Out Refinance: Which Is Better?
This is the most important question for San Diego homeowners right now. If you locked in a mortgage rate between 2020 and 2022, you likely have a rate between 2.5% and 4.5%. A cash-out refinance would replace that rate with today's rate on your entire loan balance. A HELOC sits behind your first mortgage as a second lien, so your low first-mortgage rate stays untouched.
| HELOC | Cash-Out Refi | |
|---|---|---|
| First Mortgage Rate | Stays the same | Replaced with new rate |
| Rate Type | Variable (prime + margin) | Fixed |
| Interest Charged On | Only drawn amount | Entire new loan balance |
| Closing Costs | Low to none | 2-3% of loan amount |
| Flexibility | Draw as needed, repay, redraw | Lump sum at closing |
| Close Time | 14-30 days | 30-45 days |
When a HELOC Makes the Most Sense
If your first mortgage rate is below 5%, a HELOC almost always beats a cash-out refinance. You keep your low rate on the bulk of your debt and only pay the higher HELOC rate on the smaller amount you actually need. This can save hundreds of dollars per month compared to refinancing the full balance at today's rates.
What Are Current HELOC Rates in San Diego?
HELOC rates are variable, typically calculated as the prime rate plus a margin. The margin depends on your credit score, CLTV, and the lender. As of early 2026, most HELOC rates fall between 7.5% and 10.5%. Borrowers with 740+ credit scores and lower CLTVs get the best pricing.
Because rates are variable, your payment adjusts as the prime rate changes. When the Fed cuts rates, your HELOC payment goes down automatically. Some lenders also offer fixed-rate conversion options, allowing you to lock a portion of your balance at a fixed rate while keeping the rest variable.
As a mortgage broker with access to 50+ wholesale lenders, I compare HELOC programs across multiple sources to find the best combination of rate, draw terms, and fees for each client. The rate difference between the best and worst HELOC offers can be 2% or more, so shopping matters.

Why San Diego Homeowners Are Turning to HELOCs
San Diego's real estate market has produced exceptional equity growth over the past several years. Homeowners who bought at $700,000 in 2020 may now be sitting on a property worth over $1,000,000. That is $300,000+ in equity growth — money that is locked inside the property unless you access it.
At the same time, many of these homeowners have first mortgage rates in the 2s and 3s that they rightfully do not want to give up. A HELOC solves this by adding a second lien without disturbing the first mortgage. You get access to your equity while keeping the low rate that saves you thousands every year.
