Welcome to 345 Single Avenue in New Castle, Delaware—a property offering flexibility, convenience, everyday livability, and long-term value in a highly accessible New Castle County location. Whether you are searching for a primary residence, first home, renovation opportunity, or a property you can improve over time, this home provides a strong combination of usable space, outdoor functionality, commuter access, and proximity to major employment and commercial corridors. Inside, the home offers a practical layout with additional space upstairs that may provide potential for an additional bedroom, home office, guest room, playroom, or bonus living area, subject to applicable permitting, egress, and code requirements. This added flexibility gives a future owner the ability to adapt the home as their needs change, whether that means creating more sleeping space, working from home, or simply having additional room for everyday living. The property also features off-street parking, a giant 4 car detached garage, a fenced yard, and generous outdoor space, creating added value for a primary homeowner.

Groceries, dining, retail, fitness, healthcare, and other daily necessities are all easily accessible, making the property especially convenient for everyday living. The surrounding employment base is equally impressive. Trade-area data centered around the nearby Collins Park commercial corridor shows hundreds of businesses and thousands of employees within one mile, expanding to thousands of businesses and more than one hundred thousand employees within five miles—giving this location exceptional access to employment, services, and commerce. The broader New Castle and Wilmington area supports jobs across healthcare, banking, education, government, logistics, transportation, retail, construction, hospitality, and professional services, giving residents access to a diverse regional employment market. Commuters will appreciate convenient access to Route 9, US-13, I-295, I-495, I-95, and the Delaware Memorial Bridge, providing straightforward connections throughout northern Delaware and the surrounding region.

This central location can make commuting, shopping, recreation, and regional travel significantly easier. For someone looking to make this their primary residence, the value extends beyond simply owning a home. The combination of a giant 4 car detached garage, private outdoor space, flexible interior layout, nearby shopping and dining, access to major highways, and proximity to a large employment base makes this a property that can support both everyday convenience and long-term ownership.
