There was a time that summer was the best time to list in any area that has a winter. Colorado for the last 5 years has not had a selling season. As far as selling in the spring you have one challenge, competition. Everyone still feels that the spring is the best time to list. Now a days right after new years is the best time to list your home. Get listed before your neighbors because we have buyers looking all year. Winter homes sell with less showings before contract.
