Custom built-ins in the primary walk-in closet and one bedroom, California shutters throughout, and a blend of wood-look tile and carpet on the main floor add both style and functionality. The unfinished basement provides endless potential for future living space. Step outside to the fully fenced, east-facing backyard featuring a poured concrete patio, a shed on a concrete pad, a professionally maintained sprinkler system, and a new rear fence (2025).
