If you’re weighing a cash-out refinance in San Diego right now, start with one blunt question: is the cash worth giving up the mortgage rate you already have? For most San Diego homeowners who bought or refinanced between 2020 and 2022, the answer is no — and there’s a smarter way to get the money. I’m Ron Berg, and I ran this exact math for a client this week, so let me save you the guesswork.
The short answer
- San Diego owners are sitting on near-record equity — nationally about $11 trillion is “tappable” right now (ICE Mortgage Monitor, 2026).
- A cash-out refinance replaces your whole mortgage at today’s rate — averaging 6.66% (Freddie Mac, 7/30/26). If your first mortgage is in the 3s, that’s an expensive way to borrow.
- A HELOC or home equity loan lets you keep that low first mortgage and borrow only against the equity.
- The right move is 100% about the rate on the mortgage you already have. Below is the dollar math.
Why San Diego homeowners are sitting on a pile of equity
This one’s for the homeowner who’s owned in San Diego for even a few years and keeps hearing “you’re sitting on a goldmine” — but isn’t sure how to use it without wrecking a good thing. You’re not imagining it. Home values here have climbed hard, and nationally homeowners entered 2026 with roughly $11 trillion in tappable equity — the money you can borrow while still keeping a 20% cushion (ICE Mortgage Monitor).
The catch is how you reach it. And that’s where a lot of good equity gets spent badly.
The trap: don’t torch your low first mortgage
Here’s the emotional part nobody warns you about: it feels like there’s one button marked “get my equity,” and that button is a refinance. It isn’t. If you locked a rate in the 3s during 2020–2022 — like the majority of homeowners borrowing against equity right now did (ICE) — a cash-out refinance throws that rate in the trash and re-prices your entire balance at today’s average of 6.66%.
You don’t burn down the house to get to the safe. Keep the low mortgage; borrow only against the equity.
Cash-out refinance vs. HELOC: the honest comparison
| Cash-Out Refinance | HELOC / Home Equity Loan | |
|---|---|---|
| What it does | Replaces your entire mortgage with a new, larger one | Adds a second loan behind your existing mortgage |
| Your 3% first mortgage | Gone — re-priced at today’s rate | Untouched — you keep it |
| Rate today (avg.) | ~6.66% on the whole balance | ~6.6%+ on just the amount you draw |
| Best when | Your current rate is already near today’s rates, or you want one payment | You have a low first mortgage and want to protect it |
| Watch out for | Re-pricing a huge low-rate balance to get a little cash | Variable rate on many HELOCs; disciplined payoff needed |
The real monthly math (this is what changes minds)
Percentages are abstract. Dollars aren’t. Say you bought in 2021, you owe $500,000 at 3.25%, your home is worth about $1.1M, and you want $100,000 for a remodel or to pay off high-interest debt. Here’s the same goal, two ways:
| Approach | What you carry | Est. monthly payment |
|---|---|---|
| Keep it as-is | $500K @ 3.25% | ~$2,176 |
| Cash-out refinance | $600K @ 6.66% (new full loan) | ~$3,856 |
| Keep 1st + HELOC | $500K @ 3.25% + $100K drawn | ~$2,176 + ~$600–$700 |
Read the middle row again. The cash-out refinance costs roughly $1,680 more every month — not because you borrowed $100K, but because you re-priced the other $500K you were holding at 3.25%. The HELOC route keeps that cheap money in place and prices only the new $100K. For reference, ICE pegs a $50,000 HELOC draw at about $275 a month at recent rates. (Figures are illustrations using national averages, not a quote.)
So when does a cash-out refinance actually win?
- Your current rate is already close to today’s — you’re not giving up much.
- You want a large sum and a single fixed payment, not a revolving line.
- You’re consolidating so much high-interest debt that one clean fixed loan genuinely nets out ahead.
If none of those fit, a HELOC or fixed home equity loan is usually the cleaner play. And honestly, this is the kind of “protect what you’ve built” thinking my wife Amara and I are living ourselves right now — we’re moving our own properties into a trust this year, so I’ve got asset protection on the brain. (That’s education from experience, not legal advice — loop in your estate attorney for the trust part.)
Frequently asked questions
Will a cash-out refinance always raise my rate?
If your existing rate is below today’s average of 6.66%, then yes — you’d re-price your whole balance upward. If your current rate is at or above today’s, a cash-out refinance can make sense.
How much equity can I actually access in San Diego?
Most programs let you borrow up to 80–90% of your home’s value across all loans combined, depending on the product and your credit. On San Diego’s higher values, that can be a meaningful number — which is exactly why the strategy matters.
Is a HELOC rate fixed?
Many HELOCs are variable, so the payment can move. A fixed home equity loan trades flexibility for a locked payment. Which fits depends on how fast you plan to pay it back — that’s a five-minute conversation.
