    Overview

    This duplex offers two separate residential units under one ownership. The first unit is configured with 1 bedroom and 1 full bathroom, and the second unit provides 2 bedrooms and 1 full bathroom. Both units include their own in-unit washer and dryer, and each unit has a private rear deck.

    The property is located at 623 CONCORD Avenue in Wilmington, Delaware, 19802, in New Castle County. The listing notes convenient proximity to shopping, dining, schools, parks, and major commuter routes. The property is being sold as is.

    From a tenant and owner-occupant standpoint, the unit mix supports different household needs within the same duplex footprint. The presence of in-unit laundry and private outdoor deck space can add day-to-day convenience and usable living area to each unit. As a duplex, the layout may also appeal to buyers looking to maintain separate, income-producing spaces while living in one unit or renting both, subject to their specific occupancy and leasing plans.
