Earlier quoted context omitted.
In the 90s I didn’t have a house, I was in diapers. In my experience growing up, everyone I knew could afford to buy a house on a single salary when 28-30, so that’s what I expect for myself. Anything other than that is a regression.
So, you're saying that when interest rates first dropped mega-low, people could afford a house? But... that's what caused the current problem, some say. Rates too low, for a decade, causing a housing bubble. It sounds to me like what you recall, was an aberration. EDIT: Don't get me wrong. I think the bar to home ownership should be lower. But at the same time, I think it hasn't been low, for 50+ years.
3 times annual salary seems reasonsble to me.
