Mortgage Refinancing in California: When It Makes Sense

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. I’d rather tell you not to refinance than sell you one that doesn’t pay.

Refinancing makes sense when the savings pay back your closing costs well before you expect to sell or refinance again — or when you need to change the loan itself (drop mortgage insurance, get out of an ARM, remove a co-borrower, or take cash out). With 30-year rates near 7% in late September 2026, the strongest rate-and-term candidates are borrowers at roughly 7.75% and up from 2023–2024. If you have a 2020–2021 rate, keep it and look at a HELOC instead.

I work with 40+ wholesale lenders, so I can price a refinance across conventional, jumbo, FHA, VA, and non-QM options. But the first question isn’t which lender — it’s whether you should refinance at all. Here’s how I run that analysis with clients.

Types of Refinance

The Break-Even Test

Closing costs ÷ monthly savings = months to break even. If you’ll keep the loan longer than that, the refinance pays. Examples at today’s rates:

New 30-year loans on the same balance; principal and interest only. Illustrative, not a quote.

Two refinements matter:

• Don’t ignore the term reset. Refinancing a loan with 25 years left into a new 30-year lowers the payment partly by stretching it out. Compare total interest over the time you’ll actually keep the loan, or choose a shorter term.
• No-cost refinances. A lender credit can cover your closing costs in exchange for a slightly higher rate. You start saving immediately and lose nothing if rates fall again and you refinance a second time. If you’ll keep the loan for many years, paying costs usually wins.

Seven Signs It’s Time to Look

1. Your rate is meaningfully above today’s market. Borrowers who locked in the 7.75%–8% range in 2023–2024 have the clearest case right now. Run the break-even rather than relying on a “1% rule.”
2. Your ARM is nearing its first adjustment. Start early — several months ahead gives you time to shop and lock.
3. You’re paying FHA mortgage insurance. For FHA loans with case numbers assigned since June 2013 and less than 10% down, annual MIP lasts for the life of the loan. With 20% equity, refinancing to conventional removes it — on a $700,000 FHA loan, annual MIP of 0.50%–0.55% is roughly $290–$320 a month.
4. You have conventional PMI and your home has appreciated. You may not need a refinance at all — ask your servicer about removal based on a new appraisal. See how to get rid of PMI.
5. Your credit has improved a lot. Moving from the high 600s into the 740+ range meaningfully lowers conventional pricing.
6. You want to pay the home off faster. A 15-year rate is typically well below the 30-year (6.42% vs. 7.03% in Freddie Mac’s September 24, 2026 survey), but the payment is higher: on $700,000, about $6,067 vs. $4,671.
7. Your life changed. Divorce, a co-borrower leaving, an inheritance, or a big income change can justify a refinance regardless of rates. See divorce mortgages and trust and inherited property.

When not to refinance

• You have a 2020–2021 rate in the 2s or 3s. Keep it. If you need cash, use a HELOC or home equity loan — see HELOC vs. cash-out refinance.
• You’ll likely sell before the break-even.
• Your credit or income has weakened since you bought.
• You’re near the end of your loan and most of each payment already goes to principal.

Government Streamline Options

FHA Streamline: available if your current loan is FHA-insured, you’ve made at least six payments and at least 210 days have passed since closing, you’re current, and the refinance provides a net tangible benefit (such as a meaningfully lower payment). Usually no appraisal. Note that FHA eligibility now requires permanent residency or citizenship for new case numbers (HUD ML 2025-09).

VA IRRRL: for existing VA loans. The same seasoning rules apply (six payments and 210 days), the loan must provide a net tangible benefit, and closing costs generally must be recouped within 36 months. There’s usually no appraisal, and the VA funding fee for an IRRRL is 0.5% unless you’re exempt. See VA loans in California.

Qualifying for a Refinance

• Credit: conventional commonly 620+, with the best pricing at 740–780+. Jumbo lenders often want 700–740+.
• Equity: conventional rate-and-term refinances can go up to about 95%–97% LTV in some cases; jumbo typically needs more equity; cash-out is usually capped at 80% on a primary residence.
• Debt-to-income: often up to about 45%–50% with automated underwriting.
• Loan limits: conforming up to $832,750, or up to $1,249,125 in high-cost counties like Marin, San Francisco, Alameda, Contra Costa, Los Angeles, and Orange. Above your county’s limit, it’s a jumbo refinance. See 2026 loan limits.
• Insurance: you’ll need an active homeowners policy. In fire-exposed parts of Marin and elsewhere, confirm your coverage — including any FAIR Plan policy — meets the new lender’s requirements early. See the FAIR Plan guide.

What Refinancing Costs in California

Costs typically include lender fees or points, the appraisal (often higher for large or unusual Bay Area homes), title insurance (at a lower refinance rate), escrow, recording, and prepaid interest and impounds. As a percentage, costs are often around 1%–2% of the loan, and lower as a percentage on large loans. A few California-specific points:

• No transfer tax. Documentary transfer tax applies to sales, not to refinancing your own loan.
• No Prop 13 reassessment. Refinancing isn’t a change in ownership, so your property tax base stays put — just don’t change who’s on title without checking. See the Prop 13 guide.
• Three-day right of rescission on primary-residence refinances before the loan funds.

Every refinance starts with an official Loan Estimate so you can see the rate, costs, and break-even before you commit. See California closing costs.

Marin County Refinance Notes

Most Marin refinances are high-balance or jumbo. A few patterns I see in Mill Valley, Ross, Kentfield, Larkspur, Greenbrae, San Anselmo, Fairfax, and Terra Linda:

• Jumbo borrowers from 2023–2024 with rates around 7.5%–8% have the biggest dollar savings from even modest rate improvements, because the balances are large.
• Self-employed owners who couldn’t refinance on tax returns may qualify through a bank statement program.
• ADU and remodel funding: with a low first-mortgage rate, a HELOC or renovation loan usually beats a cash-out refinance. See ADU financing.
• Insurance: homes in wildland-urban interface areas may need extra time to line up an acceptable policy before closing.

Frequently Asked Questions

When does it make sense to refinance in California?

When your closing costs divided by your monthly savings gives a break-even well inside the time you’ll keep the loan, or when you need to change the loan itself — remove mortgage insurance, exit an ARM, remove a co-borrower, or take cash out. With rates near 7% in late 2026, borrowers at roughly 7.75% and higher have the clearest rate-and-term case.

How much should rates drop before I refinance?

There’s no fixed rule. On large balances, even a 0.5%–0.75% drop can break even in under two years; on smaller loans you may need more. Run the break-even with actual Loan Estimate costs and compare total interest over the time you’ll keep the loan.

Should I refinance my 2020 or 2021 mortgage?

Usually not. Rates from 2020–2021 were far below today’s roughly 7% market. If you need cash, a HELOC or home equity loan lets you keep your low first mortgage.

Does refinancing change my property taxes?

No. Refinancing isn’t a change in ownership under Prop 13, so your assessed value doesn’t reset. Adding or removing people from title can have tax consequences, so check first.

How much does it cost to refinance in California?

Often around 1%–2% of the loan amount, including lender fees, appraisal, title, escrow, and recording, and lower as a percentage on large loans. There’s no transfer tax on a refinance. A no-cost option uses a lender credit in exchange for a slightly higher rate.

How soon can I refinance after buying?

For a conventional rate-and-term refinance there’s generally no long wait, though lenders have their own rules. Conventional cash-out requires six months on title and an existing first mortgage at least 12 months old. FHA Streamline and VA IRRRL require at least six payments and 210 days since closing.

Can I remove FHA mortgage insurance without refinancing?

If you put less than 10% down on an FHA loan with a case number assigned after June 2013, annual MIP lasts for the life of the loan, so refinancing to conventional with 20% equity is usually the way to remove it. With 10% or more down, MIP ends after 11 years.
