Adjustable Rate Mortgages (ARMs) in San Ramon
What's the difference between a 5/1 ARM and a 7/1 ARM?
A 5/1 ARM has a fixed rate for five years, then adjusts annually. A 7/1 ARM locks for seven years before adjusting. The longer fixed period typically carries a slightly higher starting rate.

San Ramon sits in Contra Costa County where the median household income of $125,727 supports homes in the $900K to $1.1M range. An ARM can be a smart choice for buyers planning to sell or refinance within five to seven years.
County infrastructure investments like the new East County Service Center in Brentwood signal long-term stability. Buyers who expect to move before rate adjustments kick in often benefit from ARM's lower initial rate.

California lenders compete aggressively on ARM pricing because the initial rate is the main selling point. Brokers can shop multiple wholesale lenders to find the best starting rate and adjustment terms for your timeline.
Lock periods typically run 17 to 21 days. Most lenders offer 3/1, 5/1, 7/1, and 10/1 ARM structures with varying fixed periods.
04
An ARM makes sense in San Ramon if you plan to sell within five to seven years or refinance before the first adjustment. The lower starting rate can save $150 to $300 per month compared to a 30-year fixed.
ARMs don't pencil for buyers who intend to stay 10+ years. Once the rate adjusts, it can climb 2% to 3% over the initial rate, making long-term payments unpredictable.
05
A 30-year fixed offers payment certainty for the full loan term. An ARM trades that certainty for a lower starting rate, betting you'll move or refinance before the adjustment.
Jumbo loans above $1,249,125 typically run 0.25% to 0.5% higher than conforming ARMs. If you're buying in that range, the ARM advantage shrinks unless you're confident about your exit timeline.
06
Brentwood's $155 million East County Service Center project signals county investment in infrastructure and services. That kind of development supports property values and makes the broader region attractive for buyers planning to hold for five to ten years.
San Ramon's proximity to employment centers in the Bay Area means many buyers refinance or relocate as careers shift. An ARM's lower initial payment can ease cash flow during the early years of ownership.
07
ARM volume in California fluctuates with rate environment. When fixed rates climb above 7%, ARMs attract more buyers seeking lower initial payments. Brokers see steady ARM demand from San Ramon buyers with clear exit timelines.
Lender appetite for ARMs remains strong across California. Wholesale lenders compete on starting rates and adjustment terms, giving brokers room to negotiate better pricing for qualified borrowers.
FAQ
A 5/1 ARM has a fixed rate for five years, then adjusts annually. A 7/1 ARM locks for seven years before adjusting. The longer fixed period typically carries a slightly higher starting rate.
Yes. You can refinance into a fixed loan or another ARM at any time. Refinancing before the first adjustment is common if rates drop or if you want payment certainty.
The rate resets based on the index plus the lender's margin. Most ARMs have annual caps (2% per year) and lifetime caps (5% to 6% above the initial rate). Your payment will increase.
Probably not. If you plan to stay 10+ years, a fixed rate offers predictable payments. ARMs work best for buyers who expect to move or refinance within the fixed period.
That depends on the index and margin. With a 2% annual cap, a $500,000 loan could see payments rise $200–$300 per year after the fixed period ends. Lifetime caps typically limit total increases to 5–6%.
