Property Description
Built in 1905 by Scottish immigrant Alex Boom, this Old Town Longmont home carries the craftsmanship and character of its era: arched doorways, rich hardwood floors, and timeless architectural details that simply cannot be replicated today. Originally constructed as a single-family home, the property was thoughtfully converted to a duplex in 1938, offering flexible use that has stood the test of decades. Today it lives beautifully and seamlessly as a spacious single-family home with 4 bedrooms and 2 full bathrooms; a rare combination of historic soul and modern livability. The sunroom adds a bright flex space, and the large kitchen has been updated with newer appliances and fresh cabinetry. The main-floor primary bedroom offers single-level living flexibility. Major updates have already been completed, including a new roof, siding, central air, and a sewer line; there is no need to worry about replacements. The professionally landscaped yard is the perfect place to relax and visit with neighbors. An oversized two-car garage completes the package. Whether you're drawn by the history, the character, or the move-in-ready condition, 825 6th Avenue is an exceptional opportunity to own a true piece of Longmont's past. Enjoy the desirable access from the front door to Downtown's breweries, coffee shops, eateries, parks, pools, and local events. Love Where You Live
