With 39,300,000 residents, California, CA sits squarely in the one of the largest metro populations in the country tier — a fact that shapes everything from bank branch density to how competitive the local mortgage market is. At 13.3% for top brackets, California's income tax is among the highest nationally — a real factor California residents should weigh when deciding between a Roth and traditional 401(k).
Home prices in California — $854,000 at the median — sit comfortably above the national average, pushing many buyers toward 30-year fixed loans with smaller down payments just to get in the door. The guides linked below turn all of this into specifics — real banks, real rates, real local rules — instead of national averages that don't apply to California.
