About This Home
Welcome to a home that truly offers the complete package of comfort, location, and lifestyle in the highly sought-after Observatory Village neighborhood of southeast Fort Collins. Nestled in a vibrant community, this home is moments from Observatory Park, the neighborhood pool with lifeguards and a dedicated wading area, and miles of scenic walking trails. You'll also enjoy complimentary access to tennis and pickleball courts, with Twin Silo Park and the Harmony Library just minutes away. The home is ideally located near major conveniences such as the Council Tree Shops, restaurants, grocery stores, and the brand-new recreation center scheduled to open in 2026. Designed for easy living and modern functionality, the home features a long list of thoughtful updates including soft-close drawers and roll-out shelves in the kitchen, ceiling fans in every room, a whole-home humidifier, ADA-height countertops, and a surround sound system that extends from inside the home to the outdoor living spaces. The freshly painted interior creates a bright and welcoming atmosphere, while the professionally refreshed landscaping, mature trees, blooming peonies, and tulip bulbs add seasonal charm and natural beauty to the yard. A custom pet door was recently added to the back slider, and a storm door was installed at the front. The finished basement provides incredible flexibility with two non-conforming bedrooms, a large living area, a game room, and extra storage. Behind the scenes, you'll find a tankless water heater for efficient comfort, a newer garage door motor and springs with wireless access installed five years ago, and a roof that was replaced at the same time with a lifetime transferable warranty. The backyard includes gas plumbing, perfect for connecting a grill or firepit. Located west of I-25 and close to highly rated schools including Zach Elementary, Kinard and Preston Middle Schools, and Fossil Ridge High School, this home offers everyday convenience with no metro tax.
