What You Get for Each Dollar in Northern Colorado
A finished basement in Northern Colorado typically returns 70–75 cents on the dollar in resale value, per Remodeling Magazine’s 2025 Cost vs. Value report — making it one of the highest-ROI renovation categories in the region. A $50,000 basement finish on a $600,000 Longmont home typically increases appraised value by $35,000–$40,000. The remaining $10,000–$15,000 “cost” buys you years of additional living space before you sell.
