No, no, you missed the first part which was the big one. 6 - 12 months of not paying your rent or mortgage can easily equal $40K+ in some places. And imagine the investors that had several properties in this scenario.
Then the stimulus on top, then the reduced expenses, etc. If you were already saving for a move you've just padded your savings in a hurry. If not, well, then you sell your current house with the highest price/equity you've ever seen, and add that to your savings from the last year. Next thing you know you're moving across the country, retaining your big city wages, with $450K in cash to buy in a market where house were going for $200K - $300K last year. You buy what you want, pay what it costs, and screw the next guy by creating a new sales comp for the appraisers.
