Local housing industry experts say a change that governs the amount buyers are required to put down when purchasing a home will significantly impact Calgary's already sluggish market.

Effective Feb. 15, 2016, the change announced by the federal government in early December will raise the minimum down payment for new insured mortgages from five to 10 per cent on the portion of the house price above $500,000.

"The intent of [the change] is to pull back demand, and they're slowing demand in a market where we're already seeing demand slow," said CREB® chief economist Ann-Marie Lurie, noting resale residential sales in Calgary have already dropped nearly 20 per cent from the 10-year average.
