Did a lot of people make pandemic house purchases? Yes. Did some of them overpay? If you call bidding $560k over asking overpaying, then yes. Are many of them happy? For those who are locked into the most ridiculous interest rates ever and are not renting anymore, heck yes.
Do some of these people regret their purchases? Of course. I personally don't know of anyone in this boat, but some are feeling remorse because they reacted in a panic. And some of these new homeowners are wanting to move, relocate, etc. But rather than give up the house and their stupidly low mortgage lock, they are opting to rent out their homes while the rental market is hot. They're becoming accidental landlords, and as a result, discovering the joys of landlord tax writeoffs.
