Description
Built in 1988, duplex, each apt at 1050 sq. ft. 3 bed, 1 bath up - L/R, EIK, rear room with W/D hookup and half-bath down. Both units renovated, ceramic tile, carpet. Water, elect separately metered and paid by tenant. Heat pumps. Parking space 1 per unit.
Plenty of in front of off-street parking. 100% leased. Current long term tenants. Owner-managed. Located in the Lake Smith area of Virginia Beach, 1 block to the lake for boating/fishing, 2 miles JEB Little Creek, Chick’s Beach, and Haygood Shopping centers.

Concern is the opportunity cost of being tied up in this property for 1 year before I am able to purchase another house hack and potentially missing a tri or quadplex (fourplex) deal. Also, both units are currently rented to low-income housing program tenants.
