Both, though the latter is a bit mixed up with more wishful thinking like "why didn't I invest everything in Apple in [early year]". Life's too full of those to really regret individual ones too much though.

I figured I'd be ok liquidating ~$300k max for a cash purchase and skipping the mortgage, though if needed it's possible to get a delayed financing loan after, and at least a HELOC. But spiking prices everywhere made that more difficult or impossible in certain areas. And even if something is 'affordable' at say $265k, I find it hard to stomach the idea of paying that much when I think it is (and 2019/2020 records show was) worth only about half that. (In 2014 I actually had legal control of a house but opted to get rid of it, it had been refinanced and it took months to find a buyer at $170k to zero that out. Earlier this year zillow estimated it could fetch $420k, which is absurd to me knowing all about it, but seeing actual sales in the area I believe it.)
