Adjustable Rate Mortgages (ARMs) in San Rafael
What does the '5' mean in a 5/1 ARM?
The rate stays fixed for 5 years, then adjusts once per year. Most San Rafael buyers sell or refi before that first adjustment.
01
San Rafael sits in one of the most expensive housing markets in the country. ARMs let buyers reduce their initial monthly payment when fixed rates are high.
HousingWire flagged a jump in ARM demand as the 30-year fixed hit 6.57%. That shift makes sense — Marin buyers are running the numbers and choosing initial savings.

Not every lender prices ARMs competitively. Some banks push fixed products because margins are easier to manage on their end.
We shop ARM pricing across 200+ wholesale lenders. The spread between the best and worst ARM quotes can be significant. Rates vary by borrower profile and market conditions.
04
A 5/1 or 7/1 ARM makes the most sense if you plan to sell or refinance within the fixed window. San Rafael's strong appreciation history supports that exit strategy.
Watch the margin and the index. A low teaser rate with a high margin will hurt you at adjustment. We read the fine print so you don't get caught off guard.
05
A fixed-rate loan gives you certainty. An ARM gives you a lower rate upfront — and in San Rafael, that gap can mean hundreds per month.
Portfolio ARMs from local lenders offer more flexible terms than agency products. Jumbo ARMs often beat 30-year fixed pricing by a full point or more.
06
Marin County property values make every basis point count. On a $1.5M loan, a 1% rate difference is $15,000 per year in interest.
San Rafael buyers often have strong income and short time horizons — exactly the profile ARMs were designed for. Many refinance before the first adjustment ever hits.
