Additional upgrades throughout the home include dual-pane windows, updated flooring and carpet, baseboards, shutters and blinds, ceiling fans in the living room and both bedrooms, and recessed lighting in the living room, primary bedroom, closets, and stairway. The finished garage has also been enhanced with new drywall, fresh paint, updated electrical outlets, a new water heater, and a new garage door equipped with a MyQ smart opener. Completing the appeal of this exceptional home is its location within the highly regarded Fountain Valley school district, including Sarah McGarvin Intermediate School 10/10, La Quinta High School 10/10, and highly rated elementary schools nearby. The Fountain Park community has a clubhouse, pool, plenty of parking and very well maintained landscape.
