Understanding Mortgages in California

California is the most expensive housing market in the United States, with a median home price well above the national average. Whether you are buying in the San Francisco Bay Area, Los Angeles, San Diego, or the more affordable Central Valley, understanding how your mortgage payment breaks down is essential for budgeting. This calculator uses California-specific defaults so you can get an accurate estimate right away.

California Housing Market Overview

As of 2026, the median home price in California hovers around $750,000 — more than double the national median. Coastal metro areas command the highest prices: San Francisco, San Jose, and parts of Los Angeles regularly see median prices above $1 million. More affordable options exist in the Inland Empire (Riverside and San Bernardino counties), the Sacramento metro area, and the Central Valley cities of Fresno and Bakersfield, where median prices can fall in the $400,000–$550,000 range. Despite periodic slowdowns, California's strong job market — anchored by technology, entertainment, healthcare, and agriculture — continues to support long-term demand for housing.

California Property Tax and Proposition 13

California's effective property tax rate of approximately 0.71% is among the lowest in the nation, thanks largely to Proposition 13. Passed by voters in 1978, Prop 13 limits the base property tax rate to 1% of a property's assessed value at the time of purchase. Crucially, annual increases in assessed value are capped at just 2% per year, regardless of how much the property actually appreciates. This means a homeowner who bought a house 20 years ago may be paying taxes on an assessed value far below the current market price. New buyers, however, are assessed at the full purchase price. Local voter-approved bonds and special assessments can add 0.1–0.5% on top of the base rate, which is why the effective rate varies by county.

Jumbo Loans and Conforming Limits in California

Because California home prices are so high, many buyers need loans that exceed the baseline conforming limit of $806,500. Most California coastal counties qualify as high-cost areas with conforming limits up to $1,209,750 for 2026. Loans above these thresholds are classified as jumbo loans, which typically require a down payment of at least 10–20%, strong credit scores (often 700+), and may carry slightly higher interest rates. If you are considering a large purchase, it is worth comparing how different down payment amounts affect your total cost — our compound interest calculator can help you evaluate the opportunity cost of a larger down payment versus investing those funds elsewhere.

Tips for California Homebuyers

First-time buyers in California should explore CalHFA (California Housing Finance Agency), which offers down payment assistance programs and below-market rate loans. The CalHFA MyHome Assistance Program can provide a deferred-payment junior loan of up to 3.5% of the purchase price for down payment or closing costs. Additionally, many California cities and counties offer their own homebuyer assistance programs. Given the high price points, getting pre-approved by multiple lenders and shopping for the best rate is especially important — even a 0.25% rate difference on a $600,000 loan saves over $30,000 in interest over 30 years.
