Bank of England to get tougher on Mortgage

The Bank of England is to impose much more stricter rules for obtaining a mortgage.
I have said previously at least twice that this will bring values of houses down and to kill the economy and it's recovery.
First time buyers will not be able to get mortgages unless they have saved about Stg50,000 for a deposit. Who can do that?
If there are no first time buyers then there is no second tier movement.
Then there will be a reduction in house building which leads to unemployment, which then leads to house repossessions!
What they hell are they doing?????
I wrote to the Bank of England to tell them this, but got a reply which basically said "Sod off, we know it all !"
Well expect me to say in 1 years time " I told you so!"
