Adjustable Rate Mortgages (ARMs) in San Diego
What's the difference between an ARM's intro rate and the adjusted rate?
The intro rate is fixed for a set period, typically 3, 5, 7, or 10 years. After that, your rate adjusts based on an index plus the lender's margin, subject to caps.
01
San Diego's median home price sits at $949,000, with homes spending 37 days on market. The county's median household income of $102,285 supports purchases across most neighborhoods.
ARMs offer a fixed intro period before rates adjust. That structure suits buyers who expect to move or refinance within that window.
At the intro rate, your payment stays locked in. Once the adjustment period begins, your rate moves with the index plus the lender's margin.
Rate caps limit how much each adjustment can move. They also set a lifetime ceiling, protecting you from runaway payments.

03
California lenders offer ARMs through both retail banks and wholesale partners that brokers like SRK CAPITAL access. Wholesale rates typically run lower than retail because brokers shop across multiple lenders.
Closing timelines average 17 to 21 days. The range depends on appraisal and underwriting complexity.
ARMs come with rate caps that vary by product. Each adjustment period has a cap, and the loan carries a lifetime ceiling.
04
ARMs make sense in San Diego when you plan to sell or refinance within 5 to 7 years. The intro rate saves money early on.
If you're staying long-term, a fixed-rate mortgage removes the adjustment risk instead.
San Diego's $949,000 median price puts most buyers in the conforming range. An ARM's lower intro rate can free up cash flow during the first years of ownership.
05
A fixed-rate mortgage locks your payment for the entire loan term. An ARM starts lower but adjusts after the intro period ends.
If you expect to move before adjustment, an ARM wins on monthly payment. If you want predictability for 30 years, fixed is the safer choice.
Both products are available at the same down-payment levels and credit requirements. The trade-off is simple: save money now with an ARM, or pay more for permanent payment certainty.
06

San Diego County counted 3,048 active listings as of late August 2026. That inventory level gives ARM borrowers more negotiating room.
Homes in San Diego are spending 37 days on market on average. That's a balanced market, not a shortage and not a fire sale.
ARMs work well in this kind of environment. Buyers can close within a normal timeline and lock in the intro rate before conditions shift.
FAQ
The intro rate is fixed for a set period, typically 3, 5, 7, or 10 years. After that, your rate adjusts based on an index plus the lender's margin, subject to caps.
Yes. You can refinance into a fixed-rate mortgage or another ARM anytime. That makes sense if rates drop or you want a fixed payment before adjustment starts.
ARMs allow as little as 3 percent down on a primary residence, with a 97 percent loan-to-value ratio. Smaller down payments bring mortgage insurance, but the lower intro rate often offsets that cost early on.
Your rate adjusts up to the cap for that period. If the index jumps more than the cap allows, the increase is limited to the cap, and a lifetime ceiling applies too.
It depends on your timeline. Selling or refinancing within 5 to 7 years favors an ARM's lower intro rate, while staying long-term favors a fixed rate for stable payments.
