I hate to be conspiratorial but there are times when I think this market is so irrational that there is some kind of larger force at play. It's not like the pandemic created more demand for homes -- if anything (and I hate to be morbid about this) there should be fewer buyers in the market and yet everything continues too tick up. And on top of that the rental market is completely irrational as well.
It's really hard not to give in to the idea that the market for housing isn't being manipulated by larger forces.
