Let’s go with Median Family income in Calgary which is 100k for a discussion of average.
https://regionaldashboard.alberta.ca...m=2013&to=2017. Let’s assume a 30% tax rate because I am to lazy to do the math.
So 70k after tax which is 5800 per month. The median detached house in Calgary is 450k so a 25yr mortgage, 5% down which is about 2k per month. Daycare might crush them as an expense. More ridiculous is that a bank would lend them about 600-650k
So the Median Family in Calgary can afford the median detached home.
