Lovingly cared for by the same owner-occupants for nearly 40 years, this classic Seward duplex sits on an oversized lot on a quiet street near the Mississippi River. The vibrant, walkable neighborhood offers easy access to walking/biking trails, restaurants, yoga, co-op grocery, and both downtowns. With three finished levels above ground, the home blends historic character—hardwood floors, built-in buffets, and original millwork—with thoughtful modern updates, including newer windows throughout, a 2022 roof on both the house and oversized 3-car garage, plus updated mechanicals and added insulation. Originally built as a duplex, it features common front and back stairways and separate laundry for each unit (second floor and basement). Both units include two bedrooms, a full bath, formal dining room with buffets, living room, spacious kitchens with abundant counters and cabinets, and two versatile spaces: a sunroom open to the living room and an ample eat-in kitchen area overlooking the backyard. The first-floor unit is bright and airy, with an open-concept view from the sunroom in front to the eat-in kitchen area in the back. The upper unit lives like a treehouse, with abundant natural light, a large deck overlooking a serene backyard pond, and a finished third-floor bedroom with skylight and convenient half bath. The upper unit also has natural woodwork on the primary living level ! The basement offers potential for future expansion of the main-level unit. Recent updates include a newer boiler and hot water heater, soft-close kitchen cabinets on the main level, freshly stained deck, interior painting, and added insulation. See Supplement. Ideal for first-time buyers who want part of their mortgage paid by a tenant, or for multi-generational living arrangements.
