About the property

Light-Filled 3BR Home in The Meadows — Basement Potential

This clean, modern 2017 home in The Meadows delivers practical everyday living plus clear upside. The open main level flows from a welcoming entry through a bright living/dining area into a well-appointed kitchen. Finishes include fresh paint, durable laminate floors, and newer appliances — systems and cosmetic updates that let you move in and enjoy the home immediately. Upstairs, the bedroom layout includes a primary suite and an efficient arrangement of additional bedrooms and baths.

The property’s standout opportunity is the unfinished basement: ready for conversion into family room, home office, media room or an extra bedroom suite — easily adding significant usable square footage and resale value. Outside, the private side yard and modest lot size mean low yard maintenance, while the attached 2-car garage and driveway provide convenient parking and storage.

Living in The Meadows brings access to community pools, tennis courts, trails and parks (confirm HOA for exact amenities and fee structure). Practical advantages include proximity to Castle Rock Adventist Hospital, nearby shopping and straightforward access to I‑25 for commuting. Whether you’re a first-time buyer, a family looking to upsize into a modern plan with expansion potential, or an investor seeking a turnkey rental with upside, this home balances immediate comfort with options to customize.

Schedule a showing with Rachel Durante at Liv Sotheby’s to walk the property, confirm HOA details, and review contractor estimates for finishing the basement — a straightforward path to creating additional family space or value.

Editorial market perspective

Castle Rock’s market in early 2026 remains competitive for well-appointed homes under $700k, particularly newer-construction product in amenity-rich subdivisions like The Meadows. Inventory has been relatively tight and median sale prices have shown modest year-over-year appreciation. Buyers are attracted to newer finishes, low-maintenance yards, and homes with additional unfinished space they can customize. For sellers, pricing within the local per‑square‑foot band and highlighting basement conversion potential typically generates quicker buyer interest. For investors, gross rent estimates for comparable 3BR homes sit in the low $3k range, making a buy-and-hold strategy viable if local expenses and HOA fees (if any) are favorable.
