Welcome to Rossmoor Highlands! Beautifully maintained and thoughtfully expanded, this inviting single-story home offers 2,109 sq. ft. of living space on a generous 7,620 sq. ft. lot in one of North Orange County's most desirable neighborhoods. Lovingly cared for by its original owners, the home features 4 bedrooms, a versatile office/den, and 3 beautifully remodeled bathrooms. A permitted addition added a bedroom and bathroom, creating a flexible floor plan suited to today's lifestyles. Inside, newly refinished solid red oak floors, fresh paint, smooth ceilings, recessed LED lighting and soaring vaulted ceilings create warmth and architectural appeal.

The adjoining dining area and breakfast bar offer welcoming spaces for everyday meals and entertaining. A separate den provides room for a home office, hobbies or potential fifth bedroom with the addition of a closet. Additional improvements include new carpeting, a new AC unit and condenser, sound wiring, Elfa closet and cabinet organizers, and a two-car garage with a built-in workbench and pull-down attic access. The outdoor living space is a standout! An expansive covered deck features a built-in BBQ, a working outdoor fireplace, ceiling fans, and plenty of room to dine, lounge and entertain. Beyond, a lush lawn, mature landscaping and a built-in, in-ground trampoline invite outdoor enjoyment. The spacious lot may also offer potential for an ADU, subject to city review and approval. Ideally situated within the highly regarded Los Alamitos Unified School District, the home is less than four miles from the beach, with shopping, dining, golf, tennis, pickleball and entertainment nearby, plus convenient access to the 405, 605 and 22 freeways.
