Although I've been "waiting" for a crash since 2013, and it still hasn't fucking shown up yet.
I will just keeping hoarding money until it happens, I suppose.
That's why I'm buying right now. I too expect a dip in values within the next couple years, but we've got cheap money right now, and I don't plan on moving again for long while, if ever.
Granted, you should do what works for you, but there is plenty to be said for purchasing a less expensive house when interest rates are higher.
My guess is that after the election's over, interest rates will start creeping up and eventually cause an overall reduction in housing values as it becomes harder for middle class incomes to afford homes at the current values.
I don't think a crash like 2008 is coming. I just think a relatively minor adjustment is right around the corner.
