It is extremely unlikely you will see falls of 50%.
Firstly we have a conservative goverment, the ideology is survival of the fittest, natural selection and free market capitalism.
Seconldy, the ingredients which caused the great recession of 2008, are missing, people do not have subprime mortgages. 2008 was caused by irresponsible lending by banks, this is a natural disaster.
So, what can the government and banks do to protect the economy.
£200 billion of QE, acts to push up assets prices.
Goverment backed loans, which are unsecured. Acts to inject money into the economy.
6 month mortgage holidays. Provides relief and management of finances.
Furlough scheme prevents defaults.
So far that has saved people from repossessions, however theres more.
Building societies such as Nationwide, are now saying they will not repossess any home for the next year, moving mortgage holders onto interest only payments..
The bank of England is now speculating, wether to have negative interest rates. If that occurs, you can effectively borrow more and pay back less.
This could act as a driver to increase house prices with easier borrowing by 15%, especially if we see -2% base rate. That may be enough to offset alot of damage.
The reality of this is, if houses loose 50%, investors will loose faith in the UK market. I would have less capital to generate other investments. I would be incentivised to join the social housing list. It would be a armogendon, seriously you actually wouldn't want to see, what you are hoping for.
It would up root most millennials whom have just done as they were told, saved hard and jumped on the ladder. Alienating future conservative voters and current.
So I would suspect, what you might find is this.
London is at the top of the bubble, so possibly 15-30% falls, which would then bounce back to new highs.
5-10% falls in areas with first rung of the ladder properties, due to the already pent up demand and bounce back even higher.
Some sales will occur, pent up demand will prevent a massive fall. Panicked sellers will look to move to remote villages, discounting more generously.
There will of course be some repossessions from overleverageed individuals, this will bring prices down and then they will recover.
If I was considering a bargain, I would be waiting for the redundancies to hit massively, watch what the goverment does and make your move. Have £30k in savings ready to pounce. There a window of opportunity yes, but it wont last forever and dont overlook the goverment and BOE capacity to prop up the market.
