Portfolio ARMs in San Francisco

California lenders compete hard on ARM pricing because the initial rate drives the sale. Most portfolio lenders hold loans in-house, meaning faster underwriting and fewer overlays.
Lock periods typically run 30 to 60 days. Appraisals and title work move quickly in San Francisco because the market is liquid.
04
Portfolio Arms make sense when you plan to sell or refinance within five to seven years. The lower starting rate saves real money upfront compared to 30-year fixed.
They don't work for buyers planning to stay 15+ years. San Francisco's median household income supports fixed-rate mortgages for most purchases.

Portfolio Arms start lower but adjust after the initial period. The savings in years one through five can be substantial, but the payment will rise when the rate resets.
