What 1980s fantasy is this 3x rule? Median household incomes to home price ratios have risen to ~8x across the US as a whole , not just crazy house price areas like SF/NYC. Canada and Australia are far worse again, pushing 15x in some cities. 3x, if it ever was a rule, has been dead for a long long time.
There's no way in hell it's close to 8x. Just crunched the numbers, and an 8x mortgage would exceed my monthly take home. I felt pretty uncomfortable at 2.5x. I feel a lot of people are probably extending out to 4 or even 5, but 8 would be irresponsible and I doubt you could even find a lender for that.
A 5x mortgage over gross pay should be just over 30% of monthly gross take home. Maybe too much for some, but not absolutely irresponsible - especially if you choose to stay in a stable housing market.
2.5x is completely ridiculous to expect - that’s going to be far below rental payments in most places that anybody would want to live. Its definitely not the norm. It’s obtainable in some areas of the northeast like Pittsburgh and the Midwest. But usually the catch is property taxes are outrageous.
