About This Home
It's not every day a property like this becomes available on Monkey Island. Located in Port Duncan, his lakefront property includes a spacious 6 bedroom, 6 bathroom home with beautiful lake views, two additional waterview lots, mature trees, and Monkey Island Marina, featuring 41 income producing boat slips currently generating rental income. The combination of a waterfront home and an established business creates an opportunity that's difficult to find on Grand Lake. The home offers multiple levels of living space with room to comfortably accommodate family, friends, and guests. The main level features two spacious living rooms, the kitchen, dining area, and the primary suite, allowing for convenient main level living. The primary suite includes a large ensuite bathroom, a walk in closet with its own washer and dryer, and access to the deck overlooking Grand Lake. Large windows across the back of the home bring in natural light while keeping the water in view throughout the main living areas. Upstairs is a private suite featuring a spacious bedroom, full bathroom, oversized walk in closet, kitchenette, and private balcony overlooking the property. It's a great setup for extended family, guests, or an owner's retreat. The walkout lower level offers four additional bedrooms plus a bunkroom attached to one of the bedrooms, three bathrooms, a large game room with a built in bar, a full laundry room, and plenty of storage. The layout provides multiple gathering spaces while giving everyone plenty of room to spread out. Outside, you'll find an abundance of deck space designed to take advantage of the lake views. The two additional buildable waterview lots add flexibility for future development, additional guest accommodations, or long term investment. Monkey Island Marina is included in the sale and features 41 income producing boat slips with renters already in place, allowing the next owner to step into an operating waterfront business from day one. Located just a golf cart ride from Shangri La Resort, championship golf, restaurants, and entertainment, this property offers a combination of lakefront living, business ownership, and investment potential that's hard to match on Monkey Island.
