I agree with you - the house price situation in London is a disaster. It is a disaster because it drives people out, because key, essential workers cannot afford to live here, especially once they wish to be a family.
What is also disastrous is the rental market. Sky high rents and no security of tenure at all, while the hapless tenant pays the owners mortgage, thank you very much. And the tax payer picks up the bill for the increasing numbers forced onto housing benefit at high rents - and the taxpayer pays the landlords mortgage, thank you very much. (disclaimer: I am not blaming or criticising people on housing benefit here)
I suspect that the new constraints on Buy To Let will simply encourage landlords to put rents up to cover it.
A rapid supply of new homes could change the situation - market forces.
And the government needs to stop bollocksing up councils' ability to provide council homes.
I am a home owner - but old enough to have paid what was nevertheless a fortune but an 'affordable' fortune for my first flat in London years ago, and bought my next after the first big crash.
My most recent home has almost doubled in value over the 10 years since I moved in, and I would be happy to see house prices tumble.
But that would be terrible for the people - young people, without property-based inheritances - struggling to pay every penny of a sky-high mortgage for a studio flat bought in the last couple of years and on a mortgage that lasts until they are 70.
But I do not find London unfriendly. I never walk down the road or through our local shopping area without bumping into at least one person I know. I fond people helpful and accepting. But it's hard if you don't feel at home because you have no stable place to call home.
