“That sounds like an Atlanta problem” one can only reasonably address this issue locally/regionally. To paint broad strokes with the national average is CRAZY disingenuous given addressing inventory deficiencies isn’t like shipping a widget from Omaha to Los Angeles.
Most people need to not worry about the national average because it is skewed (speaking of - what is the actual distribution?) - they need to worry about wherever they actually are.
ETA addressing the last paragraph of your comment: agreed! That is something to be celebrated. Wallowing in doomerism certainly doesn’t help anyone but let’s also not pretend this isn’t a very real problem people face (home unavailability).
