ARM underwriting focuses on the fully-indexed rate—the initial rate plus the margin after the fixed period ends. Lenders stress-test at the maximum rate to ensure repayment ability over the loan's life.
ARMs make sense in Woodside when you plan to sell or refinance within 5 to 7 years. The lower starting rate saves real money early, and the adjustment risk is manageable if your timeline is short.
Above $1,249,125, jumbo ARMs carry slightly higher margins but the same structural advantage. Below that limit, conforming ARMs are the most liquid option in the current market.
A 30-year fixed mortgage offers payment certainty from day one—no rate adjustment risk. An ARM trades that certainty for a lower initial rate, which works if you're not staying long-term.
Fixed rates run higher at the start but never move. ARMs start lower but adjust upward after the initial period, typically by 0.5% to 1.0% per adjustment. Lifetime caps run 5% to 6% above the initial rate.

An ARM starts with a lower rate that adjusts after the initial fixed period, typically 5 to 7 years. A fixed rate stays the same for the entire 30-year loan, offering payment certainty.
The adjustment occurs after the initial fixed period ends—usually 5, 7, or 10 years depending on the loan type. After that, the rate adjusts annually or every few years per the loan terms.
Each adjustment typically increases by 0.5% to 1.0%, with a lifetime cap of 5% to 6% above your initial rate. The cap protects you from extreme payment shock.
ARMs work best for buyers planning to sell or refinance within 5 to 7 years. If you're staying 10+ years, a fixed rate removes adjustment risk and simplifies planning.
Yes. Refinancing before the adjustment period begins lets you lock in a fixed rate or a new ARM if rates are favorable. Plan your refinance timeline early to avoid the adjustment.
