Markham September 2026 Market Update
The average fell 4.4% from last September to $1,125,353 and the median dropped 8.0% to $1,051,000. Detached held almost flat on the average, and everything below detached fell 10% or more on the median. So you have the tightest supply in York Region, 4.1 months of inventory, sitting next to a median decline that only Richmond Hill and Stouffville exceeded this month. Those two facts aren't in conflict. That's what the early part of a turn looks like: inventory burns off first, prices move last.
