Rate-and-Term Refinance in California: What It Is, When It Makes Sense, and How to Know If It’s Right for You
A rate-and-term refinance does one thing: swaps your existing mortgage for a new one at a lower rate, shorter term, or both — without pulling any equity out. No cash, no change to your loan balance. Just better terms.
Right now, the 30-year fixed is at 6.66% (Freddie Mac, week of August 27, 2026). If you bought in 2022 or 2023 when rates were sitting between 7.5% and 8.25%, the math is worth running. On a $1.5 million Marin County loan, dropping from 7.75% to 6.66% puts more than $1,100 a month back in your pocket — that’s $66,000 over five years before you factor in lifetime interest savings.
Who Should Be Looking at This Right Now
The 2022–2023 cohort is the obvious candidate. Rates peaked around 7.75%–8.25% in late 2023, and a lot of California buyers who stretched to get into a home are sitting on rates that don’t need to be there anymore. If your note rate is above 7.25%, you should at minimum run a quote.
The other group worth noting: FHA borrowers who’ve built equity. If you bought with FHA and you’re at or above 20% equity through appreciation or paydown, refinancing to conventional eliminates mortgage insurance permanently — often an additional $200–$500/month on top of the rate savings.
The Break-Even Calculation
This is the only number that matters before you refinance: total closing costs ÷ monthly savings = months to break even.
Real example on a $1.5M California loan:
- Current rate: 7.75% → $10,746/month
- New rate: 6.66% → $9,639/month
- Monthly savings: $1,107
- Closing costs: ~$22,500 (1.5%)
- Break-even: 20 months
If you’re staying in your California home another two years — which is the norm — this is a clear yes. On a $750K loan the absolute savings are smaller, but the break-even timeline works out similarly. See the full math at our California refinance break-even guide.
What You Need to Qualify
- Credit score: 620+ conventional, 580+ FHA, no minimum for VA
- Equity: 5%+ for most conventional programs
- DTI below 45%
- 6+ months on the current loan (seasoning requirement)
Jumbo refinances — above $806,500 for most counties, or $1,149,825 in Marin, San Francisco, and other high-cost CA counties — require stronger qualifications: typically 720+ credit and 20% equity. That said, jumbo rates in 2026 have been competitive with conforming, so the rate savings can still be compelling.
30-Year vs. 15-Year Refinance
The 15-year rate runs about 0.5%–0.75% below the 30-year — roughly 5.90%–6.15% today. Your monthly payment goes up about 40%, but you build equity twice as fast and cut your total interest dramatically. A lot of my clients in Tiburon and Mill Valley who are mid-career and not stretched on cash flow are making this move. It’s worth modeling both scenarios before you decide.
No-Closing-Cost Refinance Option
If you’d rather not write a $20K check at closing, a no-closing-cost refi rolls those costs into a slightly higher rate — usually 0.125%–0.25% above market. You save from month one but pay more in interest over time. If you think you’ll move or refinance again within 3–5 years, it’s often the smarter play.
