This sounds like "if everything stays the same or gets better, we will make ends meet" style financial planning. Both parents have stable or growing incomes, nobody has health problems, no surprises happen with the condo, interest rates never go up, and we don't save much for retirement.
I think it's a symptom of the lack of supply and the poorly functioning market that prices keep getting bid up to this level. It makes sense that with a lack of competitiveness on the supply side, the price of a necessity like housing will be bid up into a precarious price range for average earners. People who used to spend like this on housing would buy McMansions but now they are just hitting the table stakes point for mid-range condos or average outer suburban houses.
