20 Doris Avenue, Portsmouth, NH, 03801
About This Home
Fully renovated 3-bed, 2.5-bath Cape in one of Portsmouth's most convenient locations — and it comes with something almost impossible to find at this price: a real backyard. Nearly 12,000 sq ft of land with a brand-new patio, true privacy, and room to actually use the space. Pool, fire pit, garden — there's yard left over for all of it. Inside, everything has been done. New kitchen with new cabinetry, appliances, and lighting. Hardwood floors throughout. The layout flows naturally between living, dining, and kitchen — open without being overdone. The finished lower level adds a half bath and flexible bonus space for a home office, gym, or guest area. It's not counted in the square footage, so what you see is more than what you're paying for. Outside, a brand-new driveway and walkway give the home strong curb appeal from the street. Mini split cooling and oil heat keep it comfortable year-round. One-car garage plus extra off-street parking. Vinyl siding, asphalt roof, concrete foundation — low maintenance and built to last. Location works hard here. Portsmouth Regional Hospital is right next door — ideal for healthcare workers, nurses, and medical staff who want to walk or bike to work. About a mile to Portsmouth High School and near the golf course. Quick access to I-95 Exit 3. Minutes to downtown Portsmouth, Seacoast beaches, and Manchester-Boston Regional Airport. Target, Lowe's, restaurants, and daily services all within minutes. Vacant now — no tenants, no coordination, no waiting. Easy to show and easy to close. If outdoor space matters to you, or you work at the hospital, this is the one.
