California lenders offer ARMs through both retail banks and mortgage brokers. Broker networks often provide faster underwriting and more flexible overlays than large retail chains.
ARM pricing moves daily based on secondary market conditions. Lock periods typically run 30 to 60 days, giving borrowers time to close before rates shift.
ARMs make sense for National City buyers planning to sell or refinance within five to seven years. The lower starting rate saves real money early on, offsetting the risk of future adjustments.
For buyers staying long-term, a fixed rate removes uncertainty. ARMs carry rate-cap risk that compounds over time, making them a poor fit for buyers who want predictable payments for 30 years.
A 30-year fixed rate locks your payment for the entire loan term. An ARM starts lower but rises after the initial period, making it riskier if rates climb sharply.
Fixed-rate buyers pay more upfront for certainty. ARM buyers gamble on rates staying moderate, betting they'll sell or refinance before the first adjustment hits.

An ARM starts with a lower rate that adjusts after an initial period (typically 3, 5, 7, or 10 years). A fixed rate stays the same for 30 years. ARMs save money early but carry adjustment risk later.
Yes. Most ARM borrowers refinance into a fixed rate before the first adjustment. Refinancing requires a new appraisal and underwriting, but it locks in a fixed payment if rates cooperate.
Rate caps vary by program. Most ARMs have annual caps (2% to 5%) and lifetime caps (5% to 6% above the starting rate). Your loan documents spell out the exact limits.
Probably not. If you plan to own for 15+ years, a fixed rate removes uncertainty. ARMs work best for buyers selling or refinancing within 5 to 7 years.
