California lenders actively compete on ARM pricing for borrowers with strong credit and meaningful down payments. Broker networks often beat retail banks on rate and terms for ARM products.
ARM underwriting focuses on debt-to-income ratio and reserve strength. Most lenders require 6-12 months of reserves in the bank after closing.
ARMs make sense for Hillsborough buyers who plan to sell or refinance within seven years. Above $1,249,125, jumbo ARMs offer meaningful savings versus jumbo fixed, but rate adjustment risk rises with longer holds.
If you're staying past the initial period, a fixed rate removes guesswork. The lower ARM start rate only wins if you exit before adjustment.
A 30-year fixed ARM starts lower but adjusts upward after the initial period. Fixed-rate mortgages cost more upfront but lock your payment for life.
For buyers confident they'll move or refinance, the ARM's lower start rate adds real savings. Staying put past year seven typically favors the fixed rate's certainty.
San Mateo's Bespoke development at the former Talbot's site brings new commercial space and affordable housing downtown. That investment supports property values for Hillsborough buyers in the broader market.

ARM lending in California remains active, especially for buyers with strong credit and meaningful equity. Brokers compete aggressively on ARM pricing because the lower start rate attracts qualified borrowers.
Lenders scrutinize reserve strength and debt-to-income on ARMs more closely than fixed loans. The adjustment risk means underwriters want proof you can handle the higher payment after year five or seven.

No. ARM lenders accept 5% down with strong credit and income. 10% down is common here. 20% down eliminates PMI but isn't required.
The rate stays fixed for the initial period—5, 7, or 10 years depending on the loan. After that, it adjusts annually or semi-annually based on the index plus the lender's margin.
No. If you plan to stay past the initial period, a fixed rate removes the risk of payment shock. ARMs work best for buyers who'll sell or refinance within 5–7 years.
