It's an interesting question. Probably because at least during the 90s and early 2000s more people were long on property than short.
The idea that property was nailed on to make you money really took off in the early 00s. The middle class amateur landlords were getting heavily into BTL which was free from regulation and also relatively free from taxation. And right to buy meant a lot of property was transferring cheaply.
Popular TV programs also jumped onto the bandwagon with the media weighing in on how it was possible to make a tax free fortune slapping on a couple of coats of paint and re-doing the floor.
Of course it went off the rails a little around 2007/2008, but not enough to hurt the majority, who just sat out a minor correction and waited for the Tories to come up with a few mad schemes like HTB and funding for lending to re-inflate the market.
Then durings the 2010s continued historically low interest rates buoyed prices and the nations love affair continued, right up until around 2020, when things began to change.
Increasingly regulation with the BTL sector due to more of the electorate shifting to renting has really knocked the stuffing out of the sector and it has become more and more difficult to turn a profit. Many amateur landlords sit on properties though in the hope that house price inflation will return, all the time losing money to problem tenants. They would rather be bled slowly dry than sell something for less than they believe its worth. Tax regulation was also tightened up on.
Interest rates started heading up around 2022 and these again really knocked the stuffing out of affordability for buyers. Sellers however have remained pretty stubborn, the result being that volumes have collapsed but prices have held relatively steady. I think this reluctance/need to sell is a sign of the relative wealth tied up in older cohorts who own most of the property and are of the mentality that "house prices can only go up".
Even now if you look on here one of the top uses for money/inheritance etc seems to be for someone to help get their kids on the housing ladder, and not asking the question of why they should actually need to in the first place.
It feels like a Mexican standoff between buyers and sellers at the moment, each group waiting to see whether something turns up to make the other blink.
I can't really see much upside to the housing market at the moment. I don't see rates going that far down again. I don't see any massive wealth creation that is going to happen in the economy that will filter through to increase prices. Maybe AI is a possibility.
It's anybody's guess really though, The sentiment in my opinion has been denying the reality for years, but time and time again the market has defied my expectations and held up. The government has either juiced it or something has turned up to re-inflate it. So what do I know.
I think a final point would be is that the UK housing market is in no way homogeneous and how well you have done hanging onto property varies considerably depending on where you are and the type of property you have. A flat in the midlands may not have increased in price since 2005, and thus is worth well below what it would be expected to in real terms, whereas a family house on a good plot in the SE may have tripled in value over the same timescale. The property market though only ever seems to be discussed in terms of these massive gains though. And not the losses due to inflation from static prices.
