I just penciled out several home buying scenarios in HCOL, according to the calculators you posted, it only very recently became a questionable purchase if you don't plan on staying 7+ years in a home.
At any other point in the last 20, maybe 30-40 years if you re-finance well, it was always better to buy if you intended on living in an area for any reasonable amount of time.
