Don't be fooled -- this charming 3-bedroom, 2-bath Cape in desirable Dennis lives much larger than it looks. Soaring cathedral ceilings in the open kitchen and living area create a bright, airy feel, while beautiful hardwood floors flow throughout. Bonus finished space above the 2-car garage and a full finished basement provide even more room to spread out, work from home, or host with ease. Gas heat and central air keep things comfortable year-round. Step outside to a deck and patio with a fire pit, a brand-new outdoor shower, and nearly an acre of private, tree-lined corner lot. Golfers and beach lovers will feel right at home -- world-class courses and Dennis's stunning Cape Cod beaches are just minutes away. Space, privacy, and location: this one checks every box.
