It's unlikely there'll be a crash while interest rates are so low and mortgages have been so thoroughly stress tested since the introduction of the MMR in 2013 - it means that it's less likely people will be defaulting on mortgages, so the banks won't repossess properties and there won't be so many distressed sales, which is what really forces a downward price spiral. The thing that could change that is if we return to a higher interest rate environment - e.g. no deal brexit, run on the pound leading to a sharp jump in rates, so lots more people who might not be able to pay their mortgage.
The other factor is that there has been a big tenure shift, with the growth of the private rented sector and the entrance of institutional investors rather than private landlords. Major funds like Blackrock are much better equipped to ride out a rocky market because they've got access to patient capital, whereas the private landlord with 1 or 2 buy to let properties might be more likely to be forced to sell to release capital in the event of a wider economic downturn.
But in the long term, you won't see the house price growth that people have got used to since the 1980s. Part of this is because of the development of residential as an asset class and the entrance of investors who worry more about rental yield than price growth. It's also because affordability is very stretched - house prices are on average 8 times incomes in England, and there is, on a macro level, much lower wage growth than pre-2008, so no real potential for prices to grow in a much more regulated mortgage market. It's particularly going to bite after 2023 when there is no Help to Buy on new build. Even if you see commentators forecasting 15% house price growth over the next 5 years, if you account for inflation, it's effectively zero growth.
The lack of wage growth is also why it's much harder for people to trade up the housing ladder, and also why transactions have fallen from around 1.7 million in 2007 to 1.1 million last year.
