Cities in Colorado by Size

1. Denver

Living as a renter in Denver, Colorado, offers a unique mix of urban convenience and natural beauty, though it comes with some challenges. Denver has grown substantially over the last decade, becoming one of the most popular destinations for young professionals, students, and families. This growth has driven up the cost of living, including rent prices, which are on the high side relative to national averages. Denver’s neighborhoods each have a distinct vibe—like RiNo for artsy lofts, Capitol Hill for historic architecture, and Highland for trendy eateries—giving renters a wide range of lifestyles to choose from.

The influx of tech companies and remote workers has contributed to rising demand, making it challenging for renters to find places within their budget. Many rental properties are modern and well-equipped with amenities, but the competition often leads to quick turnarounds, meaning renters must act fast. Despite the high costs, the quality of life—bolstered by Denver’s walkable downtown, vibrant cultural scene, and year-round events—remains a big attraction. Renters also benefit from good public transportation options like RTD light-rail lines and bike-friendly streets, which make the city accessible even without a car.
