ENGLEWOOD — Demand for condominiums was once so strong, the same units could have been sold two, three or four times over while they were nothing more than blueprints, said Charlie Bray, owner of Surfside Realty.

“We sold 47 units within 45 minutes and with $20,000 down,” Bray recalled. He also remembers how one customer walked away and lost $82,000 in deposits when the real estate market collapsed with the onset of the Great Recession in 2007.
