For my U.K. readers I picked this up off the net. It seems Sir Christopher Kelly has some recommendations as MPs’complain over changes.
Sir Kelly thinks it's a "Bad day for homeowners" as an MP doesn't need to move into rental accommodation until 2015. Any capital gains on a home sold today til 2015 need to be paid back. Suposedly there is going to be some kind of agency to over see rent payments that MPs make on 2nd homes. But this could be more expensive than making a mortgage payment for some. MPs who rent now end up paying less than MPs who own a mortgage. Of course there are still plenty of cheap places to live near Westminster or of course they could always move to Sheffield! (As I noted in a previous post it's one of the cheapest places to live in England)
