This spacious South Dartmouth home offers a warm, flexible layout with 4 bedrooms, 2 baths, and plenty of room to grow. A beautiful farmers porch sets the tone from the moment you arrive—an inviting spot for morning coffee, evening unwinding, or simply enjoying the neighborhood’s quiet charm. The curb appeal is further enhanced by a brand-new roof, giving the next owner peace of mind for years to come.Inside, the first floor welcomes you with hardwood floors and an eat-in kitchen that includes a convenient pantry off the hallway. The living areas flow easily toward the two-tier deck, where sliders on both levels make indoor–outdoor living feel effortless. Downstairs, the finished basement—also with hardwood—adds valuable bonus space for relaxing, working out, or hosting guests. A full walkout egress expands its potential even further, offering natural light, easy access to the yard, and the opportunity to create a private suite, home office, or recreation area with its own entrance. The second floor is where the possibilities really open up. You’ll find two extra-large dormitory-style rooms (15.2 × 23.2 and 16.2 × 23.2), perfect for transforming into a master suite, a private in-law unit, or a pair of oversized bedrooms with room for work, play, or storage. This level also features central AC, while the home’s two heating systems keep things comfortable throughout New England’s seasons. The kitchen and baths could use a refresh, giving the next owner a chance to add personal style and value. With its generous square footage, flexible layout, farmers porch, new roof, walkout lower level, and convenient South Dartmouth location, this home offers a solid foundation and exciting potential for someone ready to make it their own.

Estimates — not financial advice
These figures are illustrative estimates for informational purposes only — not an appraisal, valuation, or guarantee of rent, income, or returns, and not financial, tax, or investment advice. Rent is either the figure reported on the MLS listing — in-place rent that may differ from market and is not verified against the actual leases — or, where the listing reports none, an estimate from HUD Small Area Fair Market Rents, a government benchmark that may differ from actual market rent. Each figure is labelled with its source. Cap rate, NOI, and returns depend on the assumptions shown, which you can change. MLS and other third-party data may be inaccurate or out of date. Verify all figures independently and consult your own financial, tax, and legal advisors before making any investment decision.
