How will latest Help to Buy scheme work? A scheme designed to help people across the UK to take out 95% mortgages is being extended to cover older properties - three months earlier than planned. Help to Buy was launched in April for those who wanted to buy a new build property but did not have a big enough deposit. Ray Boulger from independent mortgage brokers John Charcol told BBC Breakfast that in reality nobody would be able to complete on a purchase before the end of 2013. The only lenders who've committed so far are the two banks who are partially state-owned - the fact they've been prepared to commit without knowing the full details of the scheme, I think, tells you a lot.
