What refinancing looks like in San Francisco at today's rates

The median home in San Francisco costs about $425,000. Refinancing a typical balance of $340,000 (80% of that value) at today's average 30-year fixed rate in California of 6.59% works out to roughly $2,169/month in principal and interest, with $440,991 of total interest over the 30-year term.

Here is how the monthly payment and break-even point change if you wait for (or negotiate) a lower rate, assuming closing costs of $8,500 (2.5% of the loan):

Estimates use principal and interest only and today's average California rate; they exclude taxes, insurance, and rate differences from credit score or loan size.

Weighing the term itself? At today's California average 15-year fixed rate of 5.70%, the same $340,000 balance costs $2,814/month over 15 years — $645/month more than the 30-year fixed option, but with $274,515 less interest paid over the life of the loan.

Should I Refinance to 30-Year to Eliminate PMI in San Francisco?

Absolutely-if you're paying PMI, refinancing to 30-year in San Francisco's growing market can eliminate it permanently. PMI costs 0.5-1.5% of your loan annually ($283-$425/month). With 7.8% appreciation, if you purchased 2-3 years ago with less than 20% down, you've likely crossed 20% equity. Refinancing a $340,000 loan removes PMI even if you get the same 30-year rate. Combine with a rate reduction (7%→6% saves $224/month) and eliminate $283/month PMI for total savings of $507/month.

How Quickly Can I Build Equity with a 30-Year Refi in San Francisco?

The 30-year term builds equity through both principal paydown and San Francisco's 7.8% appreciation. On a $340,000loan at 6%, you'll pay down approximately $6,800 in principal the first year. Add San Francisco's $33,150 annual appreciation, and your total equity grows $39,950/year. After 5 years: $199,750 in combined equity. The 30-year term keeps payments low ($2,038 P&I + $269 property tax) while growth accelerates equity.

When Should I Refinance to 30-Year in San Francisco's Growing Market?

Refinance when: 1) Rates drop 0.75%+ below your current rate, 2) You've built 20% equity to eliminate PMI, or 3) You want lower payments while San Francisco's 7.8% appreciation builds equity. Don't wait for perfect timing-on a $340,000 loan, even a 0.5% improvement saves $113/month. With $8,500 closing costs, break-even is 75 months on a 7%→6.5% refi. Growing markets favor refinancing sooner since equity buildup accelerates over time.

Should I Use 30-Year Cash-Out Refi for Home Improvements in San Francisco?

Strategic in growing markets where improvements compound with appreciation. With 7.8% growth, a $50k kitchen remodel doesn't just add immediate value-it appreciates with your home. If you have $127,500 equity on San Francisco's $425,000 median home, you can access up to $42,500 while keeping 20% equity. Cash-out 30-year rates are 0.25-0.5% higher, but the extended term keeps payments manageable: adding $50k to a $340,000 loan at 6.5% increases payment only $316/month.

How Do San Francisco's Property Taxes Affect 30-Year Refi Savings?

Property taxes at 0.76% add $269/month to San Francisco's median home payment. When refinancing to 30-year, remember: your P&I payment decreases (7%→6% saves $224/month on $340,000), but property tax stays constant. Your total PITI drops from $2,681 to $2,457. Also note: as your home appreciates 7.8% annually, assessed value may increase, gradually raising property tax over the 30-year term. Factor this into long-term budgeting.
