This Tudor-style beauty has been completely and thoughtfully brought back to life, blending original character with modern, move-in-ready comfort. Every major system has been renewed from the ground up: new plumbing, new wiring, a new roof, and gas forced-air heat paired with central air keep this home efficient and comfortable through every Montana season. Inside, the full remodel continues with a brand-new kitchen featuring stainless steel appliances, new flooring throughout, and new windows that fill the home with natural light while preserving its classic charm. Three bedrooms and one and a half updated bathrooms offer flexible, comfortable living space for everyday, a home office setup, or hosting guests. What makes this home special is how well the remodel respects its roots - the original character and detail that give the home its warmth are still very much intact, now paired with the amenities today's buyers expect. It's a rare combination: the craftsmanship of an established home with the peace of mind of all-new mechanicals. Outside, the home sits on a generous 14,700 square foot city lot, offering plenty of room to garden, entertain, or simply enjoy some extra space in town. It's a setting that gives you both space and possibilities all within Sidney's city limits. Homes that have been renewed this thoroughly, inside and out, don't come along often. 403 4th St SE Sidney, MT offers the best of both worlds - timeless style and worry-free, modern living. Come see for yourself what a truly complete remodel looks like.
