When it comes to noncoastal metro areas with the most expensive home prices, Colorado takes spots one to four, with Greeley now on the highest-cost list, according to a study from the real estate research firm Zonda. “Housing affordability generally improves as one moves away from the coast, but even inland markets are reaching affordability extremes,” said Ali Wolf, Zonda’s chief economist, in a blog post that highlights just how expensive it has become to live along Colorado’s Front Range. Wolf set out to identify the five most expensive noncoastal markets with a population of 250,000 or more, and her report also includes lists for the top five in 1980, 1990, 2000 and 2010. Boulder tops the list with a median home price of $833,622 and Denver came in next at $636,651.
