Welcome to a truly unique and hard-to-find home in the heart of Plainview offering approximately 3, 389 square feet of total usable space. This is the kind of layout buyers are constantly searching for but rarely find; expansive, adaptable, and capable of living beautifully in multiple ways. Currently configured with 6 bedrooms, with one of the rooms being used as a giant first-floor home office, it can easily be brought back to bedroom use if desired. The main level immediately impresses with its scale, offering a huge living room, oversized room, dining area, kitchen, full bath, and a massive first-floor bedroom/office measuring approximately 11'2" x 25'1". Whether you need first-floor living, a private workspace, extended accommodations, guest space, or simply room to spread out, this home delivers. Upstairs, the flexibility continues with multiple bedrooms, additional bathrooms, a second kitchen, flexible living space, laundry machines, and access that allows the home to function seamlessly for extended housemates, guests, or a more private living arrangement. The home is legally set up with options for both separate and interior access, but it also works beautifully as one large residence for anyone who wants serious space without sacrificing comfort or privacy. Outdoor living is another major highlight, with a backyard, a main-level deck, and an upstairs deck creating multiple places to relax, entertain, or enjoy a little separation between living areas. Additional features include newer central air conditioning, 3 zone heating, and a basement that is half finished, offering even more space for storage, recreation, hobbies, fitness, or future possibilities. Even better, this home is currently protected by a home warranty, which may convey to the next owner, giving buyers added peace of mind from the day they take ownership. It is one more layer of confidence for a home that already offers so much space, flexibility, and long-term value. With approximately 3, 389 square feet of total space, 3 full bathrooms, a current 6-bedroom-capable layout, an oversized first-floor office/bedroom, newer AC, 3 zone heat, backyard, multiple decks, basement space, potential warranty protection, and a footprint that adapts to real life, 21 Audrey Avenue checks the boxes that most homes cannot touch. Plainview continues to be one of Nassau County’s most desirable Long Island communities, known for its suburban feel, convenience, parks, restaurants, shopping, access to major roadways, and the Plainview-Old Bethpage Central School District. The Long Island Railroad is approximately 0.3 miles from the house, offering an incredibly convenient commute. Homes like this do not come around often. Spacious, flexible, practical, protected, and loaded with possibility, 21 Audrey Avenue is the one buyers have been waiting for. As a legal 2-family home, it offers rare versatility for today’s buyer. Use it as one big beautiful residence, create a multi-generational living setup, explore mortgage-hack possibilities, or take advantage of its income-producing potential. However you choose to live, this home gives you options most properties simply cannot.
