Perched at the end of a cul-de-sac on over half an acre, this San Mateo Hills home offers breathtaking views of the Bay, San Francisco skyline and western hills. Upstairs, the primary suite features an updated bath and a private deck shared with an adjacent bedroom both with stunning views. A third bedroom and updated hall bath complete the level. The lower level is designed for seamless indoor-outdoor living. The living room, with a wood-burning fireplace, opens to a patio with hillside views. The eat-in kitchen offers abundant cabinetry, an updated tile floor, a pass-through to the dining room, and access to a private patio. Sliding doors from the dining room lead to the backyard, where the hillside landscaping features young fruit trees. The backyard patio and side garden offer a raised garden bed, and a serene canyon backdrop. A concept rendering illustrates how adding a deck over the hillside could beautifully expand the entertainment space and enhance the sweeping views. A versatile family room has a separate side entrance. Additional features include an interior laundry area, ample storage, and a two-car garage. Ideally located near shopping, dining, and major highways, this move-in-ready home offers privacy, convenience, and incredible vistas.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
