February saw the average price of a single-family home in metro Denver pass the half-million-dollar mark, according to the Denver Metro Association of Realtors market trends report, issued today. The average price was $502,986, up almost 12 percent from February 2017. “This may represent a psychological barrier for some homebuyers wishing to enter the market,” said Steve Danyliw, chairman of the DMAR Market Trends Committee.
