Based on the $343,000 house price, and the 3%/7% rate difference they mention between 2020 and 2024, the mortgage on a house the exact same price would've gone up from $1900/mo to $2650/mo. That alone is already a 40% increase.
Obviously houses prices have inflated along with everything else, but the pain is really mostly coming from the increased mortgage rates. Even a cheaper house would still be painfully more expensive today.
What I wonder is... when would it make sense to try to return to a low interest rate environment (if ever)? Is there a point where we think it will?
