It's not all or nothing; only upwards or only downwards forever...
I've seen 3 significant corrections in my lifetime and there absolutely will be more in the future.
No one thinks that prices are going to go on a multi decade decline or anything ridiculous like that; the last time that happened was in the 1800's; we're talking about the possibility of 1-2 years of cooling and the unwinding of pandemic related house price inflation; that's what most people would consider a correction, and from what I can see, it's already beginning.
I'm sorry that you think that makes me deluded... I'm a homeowner and I don't want to see my house devalue, but I like pouring over data and that's my interpretation.
In fact, I would argue that thinking the're always going up in a straight line, in the way that you appear to, is what's deluded; they never have done throughout history, so why would they in future?
I specifically referred to deluded people as to those who believe there will be a crash and reduction of prices (large scale country wide I mean) of 50% or more in our life times. That won't happen even as a very short term blip, or over a long period of time either. There is zero chance in a fully functional UK economy. You seem to have confused that I am referring to delusional people as those that think there will be a smaller "correction" of the likes which you suggest.
