for $595,000 with 2 bedrooms and 2 full baths. This 2,173 square foot home was built in 1900 on a lot size of 0.22.
Some homes have character. Others have history. **The Nowlen House has both.** Built in 1900 and recognized as one of Longmont's historic homes, this beautifully preserved Queen Anne Victorian residence offers a rare chance to own a piece of the city's story—without sacrificing the comforts of modern living. Set beneath the canopy of one of the oldest cottonwood trees in Colorado, this unforgettable property combines architectural charm, thoughtful updates, and a little bit of magic. Inside, you'll find 2 bedrooms, 2 full baths, a flexible bonus space, and a beautifully finished basement that adds valuable living space. Original details and timeless craftsmanship have been lovingly preserved, while extensive renovations make everyday life easy. Fresh interior and exterior paint, a newer roof and gutters, remodeled spaces, and a blend of original and new flooring create the perfect balance of old-house soul and modern convenience. The large lot offers room to spread out, garden, entertain, or simply enjoy the shade of that legendary cottonwood. A detached garage and charming chicken coop complete the picture—because life is just better when fresh eggs are part of the equation. Nestled in Longmont's beloved Collyer neighborhood, you're just minutes from downtown Main Street's shops, restaurants, breweries, coffee stops, and weekend strolls. Parks, trails, and outdoor adventures are seemingly around every corner, making it easy to embrace Colorado living. The Nowlen House isn't a cookie-cutter home—and thank goodness for that. It's a place where stories have been told for more than a century, where historic charm meets modern comfort, and where the next chapter is waiting to be written.
