More than a home, it's a piece of Longmont's history. This charming two-bedroom, one-bath Historic East Side cottage was once the home of Amos Millice. A Civil War veteran and early Longmont pioneer, Millice helped lay out the very streets of downtown. The home's original craftsmanship and character have been perfectly preserved, while thoughtful updates make it a welcoming, modern sanctuary - complete with gig internet. Vintage charm shines through with details like a high-tank toilet and a classic clawfoot tub. Enjoy the remodeled kitchen complete with slow-close drawers and stunning wood inlay detail in the floor. The new owners will appreciate the efficient wood-clad Andersen windows, a cold-climate heat pump, and flat-textured walls with fresh paint. The basement offers plenty of room to expand. The property also features an oversized, heated garage with a unique design. Its movable walls allow for a variety of uses, from a workshop to a massive maker space. Thanks to recent changes in Colorado law, you can explore the option of converting it into a permitted two-bedroom home or ADU. The large lot and backyard are a true urban oasis. Enjoy multiple sandstone patios, a serene pond, a dog run, and lush green grass. With alley access and a wide driveway, you'll find plenty of parking for all your vehicles and toys. The roof was replaced in 2021, and this home may qualify for a community reinvestment act grant that could provide a credit of 1.75% of the loan amount toward closing costs, pre-paids, and discount points, up to a maximum of $7,000.
