Based on what I know about Denver, people there want to live outside the city, not in Denver itself. Everyone I know that moved to "Denver" actually moved somewhere like an hour's drive from downtown, and not because they couldn't afford something in the city. Here's a map of average housing prices in the area: https://www.arcgis.com/apps/dashboards/3e87d9f631dd470ab05ab.... There are some expensive neighborhoods in the city, but I think this map looks very different from most other American cities.
