Experience the best of Huntington Harbour waterfront living at 3742 Montego Drive, ideally positioned in one of Seagate's most desirable locations. Set along the large lagoon, this waterfront townhome offers a peaceful setting away from the noise and activity of the main marina, while still providing effortless access to Huntington Harbor. A standout feature is the private 16x30 deep-water boat slip, included in the property's legal description and conveying with the home, offering ownership rather than simply an assigned slip. Enjoy the best of both worlds: the boating lifestyle with your own deep-water slip, while your home overlooks the quieter lagoon away from the constant marina activity. The south-facing waterfront patio and living spaces enjoy natural light and beautiful lagoon views, while the home's positioning helps minimize harsh direct sun, creating a comfortable setting for relaxing and entertaining. Offering 3 bedrooms, 3 bathrooms, and approximately 1,890 square feet, the light-filled interior blends coastal charm with thoughtful upgrades. The main level features a welcoming entry, spacious living room with fireplace, recessed lighting, and large sliding doors opening directly to the waterfront patio and tranquil lagoon views. The dining area flows into the upgraded kitchen featuring newer appliances and hardware. Additional improvements include newer ceiling fans with remotes, closet doors, faucets, door hardware, refrigerator, dishwasher, washer, and dryer. Upstairs, the primary suite features vaulted ceilings, beautiful lagoon views, and a remodeled en-suite bathroom with a frameless glass shower. An enclosed third-floor bonus room provides flexible space for a home office, hobby room, or additional storage. Major system improvements include a newer HVAC system and ducting and a tankless water heater, with the furnace and water heater relocated to the attic to maximize usable space. The laundry area has been framed with a door and closet, while a newer block wall enhances the privacy of the front courtyard. Seagate residents enjoy resort-style amenities including two pools, six tennis courts, a clubhouse, lush greenbelts, and direct lagoon access. Just minutes from the beach, dining, shopping, and everything Huntington Harbour has to offer, this is a rare opportunity to own an upgraded waterfront home with expansive lagoon views, a peaceful location, and an owned 16x30 deep-water boat slip in one of Seagate's hidden-gem settings.
