I (age 60) remember buying my condo in 1991 or so, interest rates about 7% with a VA-guaranteed loan. My parent's first mortgage was 2% or 3% but my mom, a Realtor, said those days were permanently gone. (They weren't. I had that in the house I bought in 2010.) But it felt forever at the time, and she thought it would be forever.
Nothing is forever. It may crash, but something else we can't imagine might happen too. I think we all agree the present situation is unsustainable.
