Description
INVESTORS & CONTRACTORS TAKE NOTICE! This is the West End restoration opportunity you’ve been waiting for. Located just a 10-minute stroll from the heart of downtown Portsmouth, this stately duplex offers a rare “blank canvas” for those looking to create a masterpiece in one of the Seacoast’s most desirable neighborhoods.
Currently occupied and functioning as a two-family residence, this property is home to families on both the first and second floors. While the home requires significant rehabilitation and a “top-to-bottom” vision, its solid bones and classic New England character remain intact. Whether you are looking for a high-yield investment project, a condo conversion opportunity (CD4-L2 Zoning), or a “sweat equity” dream home where you can live in one unit while restoring the other, the potential here is unmatched.
You simply cannot beat this location. Enjoy the best of Portsmouth’s West End! Walk to local coffee shops, award-winning restaurants, and the vibrant energy of Market Square in minutes. Properties in this corridor, especially those with this much “value-add” potential, are becoming increasingly rare.
Property Highlights: Versatile Duplex Layout: Separate units on the first and second floors. Premium West End Corridor: High-demand area with strong historical appreciation. Zoning Potential: CD4-L2 district offers various development or conversion paths. Rare amenities: Enjoy a spacious, fenced-in backyard and the incredible convenience of TWO separate driveways providing rare off-street parking for both units. Livable Restoration: Currently housing two families, providing immediate functionality while you plan your renovation.
Bring your contractor, your architect, and your vision. 413 Islington St is ready for its next chapter. Sold “as-is.”
