There's been multiple corrections over the last 35 years; over a long enough time period they're fairly common.
what is different this time so far?
Average mortgage affordability versus average wages is at levels last seen just before the house price crash of 1989, and if rates end up going above around 6%, then that could put mortgaged homeowners at a level of financial burden not seen since the 1800's.
Landlords are selling up at a rate of knots, which is only adding to supply, and the governments of developed nations have no wiggle room to perform any more QE.
A decade's worth of ultra cheap debt is currently priced into the housing market, and that cheap debt has just been pulled away.
In my opinion there's only so many ways to balance that equation.
Also define massive....2008 "massive"? That wasn't massive, despite that people claim it was.
I've been saying for the last 6-8 months in this thread that I think that it's fairly likely that the 20%+ Covid house price bubble is going to unwind slowly over the next couple of years, and events over the last 2-3 weeks have further solidified that position for me.
So far the data seems to be pretty supportive of that forecast, and I actually now wouldn't be completely surprised if we saw some regional drops that exceed that peak to trough.
Hey ho... I know it's an unpopular opinion. But it's just what my interpretation of the data suggests.
