The concept of a mortgage deposit is now outdated and a nonsense

And if Mr Noonan was really serious about helping people to get on a property ladder, and tackling bank collusion, he would address the issue of banks requiring a deposit before they approve lending.
That requirement is an outdated throwback to a time when one man’s income (and it was always a man, as women weren’t allowed have a mortgage unless a man was guarantor) was sufficient to support a family.
