One of the largest Echo Park housing developments to take shape in more than 20 years will officially start selling condominiums on Saturday. Sales at the 36 on Echo project will begin with a grand opening of a model home and tours of the 36 unit project, which is still under construction at the corner of Echo Park and Delta avenues. What will it cost to live in Echo Park’s newest condo complex? Jim Mahboubian, a sales agent for developer D.R. Horton, said prices for the condos – which range from about 1,200 to 1,700-square feet will start in the high $400,000 range. Four of the units have already been reserved by interested buyers, he said. Guess we will have to wait until Saturday morning to find out how much it will cost to buy a condo with a view of Magic Gas (Echo Fuels) and Chango Coffee.
