About This Home

As of August 2025

Charming, Updated & Deceptively Spacious Home in Custer This beautifully updated home on Montgomery Street delivers incredible value in one of Custer’s most desirable neighborhoods. Tucked away on a private 0.38-acre lot, it blends vintage character with thoughtful modern upgrades, making it move-in ready while offering room to grow. The main level includes two spacious bedrooms and an office/den that could serve as a non-conforming third bedroom. Fourteen new windows upstairs flood the home with natural light and improve energy efficiency. The kitchen has been refreshed with new appliances, and a new pellet stove provides cozy, cost-effective warmth throughout the living space. The main floor bathroom features a stylish and functional new shower system, and the home's layout flows well for both everyday living & entertaining. Downstairs, the finished basement adds even more versatility, featuring a large family or den area, a full bathroom, a laundry room, and generous storage. A spacious workshop area offers ideal space for hobbies, projects, or even future bedroom expansion. Outside, the property boasts a newly fenced backyard with mature landscaping, garden space, and a concrete driveway. A detached garage provides additional parking or storage options. With its spacious layout, quality updates, and price under $400,000, this home stands out as a rare find in the current Custer market. The property has already been pre-inspected and is ready for its next proud owner.
