Sonora sits in Tuolumne County's Sierra Nevada foothills. Properties here move differently than coastal California — and ARM loans can fit that rhythm well.
HousingWire flagged that ARM demand is shifting as 30-year fixed rates hit 6.57% as of early April 2026. That shift makes sense for buyers who plan to move or refinance within 5-7 years.
