The horse bolted 10 years ago , the jockey ie Central Bank/Regulators were either incompetent or believed their Banking friends.
Do not forget The Central Banks main function is to protect their Banking friends, any positive effect on housing/consumers is but a happy bye product.
I would (from experience) be very wary of giving good motives to Central Bank.
The proposals though are I think mostly sensible.
The future;
I would not be atall surprised to find lenders (as was their practice) soon start to tweak income. Sellers to tweak prices (a bit of cash here and there) and since none of this can be properly proven and given our love affair with property Central Bank will ignore.
Then maybe not , they could always fine their friends;
probably 50 euro would be nuff! it wouldn,t do to frighten Banks !
