California mortgage payments include unique costs that don't exist in most states. Prop 13 keeps property taxes artificially low at ~1% of purchase price (not market value), but conforming loan limits are sky-high — $1,149,825 in most coastal counties, meaning even modest homes may need jumbo loans. Median home price statewide is over $800,000. This calculator factors in CA-specific conforming limits by county, Prop 13 tax estimates, and PMI thresholds.

Frequently Asked Questions
What is the conforming loan limit in California?
For 2024, most California coastal counties (LA, SF, Orange, San Mateo, Santa Clara) have a conforming limit of $1,149,825. Inland counties like Sacramento are at $766,550. Loans above these limits require jumbo financing at typically 0.25-0.5% higher rates.
How does Prop 13 affect my mortgage payment?
Prop 13 caps your property tax at ~1% of the purchase price (plus ~0.1-0.3% in local bonds), increasing only 2% per year. This makes CA property taxes very predictable and often lower than other high-cost states like New Jersey or Texas.
How much house can I afford in California?
With a $150K household income and 20% down, you can typically afford a home around $750,000-$850,000 in California. In expensive areas like SF or LA, this may only buy a condo or require moving to suburbs.
What is the average mortgage rate in California?
California mortgage rates track national averages closely, typically within 0.1-0.2%. Jumbo rates may actually be slightly lower than conforming in CA due to the competitive jumbo market and strong borrower profiles.
Should I get a 15-year or 30-year mortgage in California?
With CA's high home prices, most buyers choose 30-year mortgages for lower monthly payments. A 15-year on an $800K home at 20% down would require ~$4,800/month in P&I alone. Consider 30-year with extra payments instead.
