House prices in my area have quintupled since I moved here 13 years ago. A 20% drop would move house prices back to where they were perhaps 4 years ago. And now that interest rates are double what they were, housing affordability is as bad as its ever been.
As someone who has spent the last decade watching home ownership get farther and farther out of reach, it's really depressing. It really will never get any better than it was, and I'm fairly confident I've missed my chance at home ownership.
