Before you read a single word about this home's finishes or its backyard, there's one extraordinary feature you should know: 3052 Bostonian Drive comes with an assumable $1.14 million mortgage at 2.375% interest, with about 25 years remaining. In a market where buyers are financing at 6.4% or higher, this is not a footnote, it's the headline. Set behind a classic white picket fence, 3052 Bostonian Drive welcomes you with storybook curb appeal, mature landscaping, and the warmth and character Rossmoor homes are known for. Inside, the well designed floor plan offers three large bedrooms, including a primary suite with an en suite bathroom and a sliding glass door opening to the backyard. Expansive living spaces and an abundant natural light add to the home's inviting feel.The spacious living room makes an immediate impression with its vaulted, beamed ceiling, fireplace, built-in bookcases, and charming window seats. A second oversized family room adds even more flexibility, featuring parquet wood flooring, a brick fireplace, built-in shelving, a vaulted ceiling, and direct access to the backyard. At the heart of the home, the updated kitchen blends character and function with soft green cabinetry, a large center island, abundant storage, brick accents, and a coordinated suite of premium appliances. Open sightlines to the dining and living areas create an easy flow for everyday living, while a direct door to the outdoor kitchen makes entertaining especially convenient.The backyard is entirely brand new, completed within the past two years and designed from the ground up for year-round Southern California living. A sparkling new pool and spa with water features anchor the space, while a covered entertaining area and a built-in outdoor chef's kitchen, equipped for grilling and al fresco dining, set the stage for entertaining. A gas firepit completes the setting, offering another place to gather under the stars. This is not a refreshed backyard. It is a ground-up resort transformation. Located in the sought-after Rossmoor community near parks, shopping, dining, beaches, and the award-winning schools of the Los Alamitos Unified School District, this home presents a rare combination of character, generous living space, and recent improvements including new HVAC and electrical. But the opportunity that truly sets it apart is the one no other listing in this market can offer: a 2.375% assumable mortgage that puts $1.5 million back in a buyer's pocket over time.
