You have no crystal ball and if you have such great insight, you wouldn't be on Mumsnet speculating about future house prices. Frankly you'd be to rich to care...
Now, although what you've said makes sense, while you use you understanding of economics to draw authority and confidence.
There have been several property crashes in the past and the government has always acted to prop the market up.
Its dangerous, to influence a buyer to determine where the bottom of this market is, if there is a bottom. They may just find, in 12 months they are now priced out of that area.
You also, have no control over the governments interventions and seem to assume these are used up. As everyone did in 2008 and to their surprise, whilst nobody sold because of lost confidence and negative equity, supply was restricted and higher deposits reduced, FTB demand.
So be careful, as the future may not turn out as you intend, during the spanish flu, house prices rose 20% in this country and other parts of the world.
Remember interest rates are at 0.1%, this will incentivise, people to move money into assets. Theres alot of cash holders out there buying up assets right now. If they go negative which the BOE is resisting, then cash will flood out of the banks.
There are many tools left in the BOE and Governments arsenal. Such as Mortgage tax relief, negative interest rates and new props... just look towards Australia and scotland, recently extending HTB to all homes. The EU central bank is negative on rates and some countries already offer negative rate interest mortgages.
Your hoping the path with follow your trajectory, however you fail to give weight to exactly who keeps the Tories in power. The main Key are boomers whom are house owners, what your hoping for would see 100,000s of people lose their homes. Not to mention all the equity release schemes and interest only mortgages, these individuals hold. It would be carnage, the health and social care system would collapse, through lack of funding from these sales.
The Tories are funded through donations, from these very individuals, money talks and the last thing they will want is to slap these very people in the face, as they will replace them.
So, I would agree with everything you've said and assume the path you've given is absolutely correct, if there wasn't any goverment influence. You're forgetting who keeps the Tories in power and there interests.
It's just as likely, they deregulate further, reducing standards of living within houses. Encouraging co-living and pushing immigration through the roof, they've just offered 3 Million HK residents potential citzenship. Do you not assume, when Brexit is done, that we wont have mass immigration? From other countries...
As, I said you have no crystal ball...
