What’s special

1-car garage
Rare Opportunity for a Historic 1927 Home with Endless Potential! Nestled in the highly desirable Country Club subdivision of Mount Prospect, this classic 1927 residence enjoys an exceptional setting near St. Raymond School, Weller Creek and Park, and the Mount Prospect Golf Club. Offering over 3,000 square feet of living space Plus a full finished basement, the home is rich in character and historic charm, reflecting decades of thoughtful care. The interior was lovingly remodeled in the early 1990s with great respect for the home's original architectural integrity, preserving its timeless appeal and historic value. Hardwood flooring runs throughout much of the home, and a four-season room seamlessly connects to the main living area, providing additional flexible space to enjoy year-round. Important mechanical updates include a new roof installed approximately two years ago, along with a boiler and water heater replaced around ten years ago. While the home does require updating, it presents an outstanding opportunity for those looking to restore, enhance, or reimagine a truly special property. Currently tenant-occupied, the home is leased through the end of July 2026, with occupancy available August 1, 2026. This makes it an excellent option for investors seeking a property in a prime location with strong long-term potential. A rare chance to own a historic home with substance, setting, and significant upside. Property being sold As Is.
