1 Bedroom flats & CGT exemption ending

Quite a bit of speculation in various threads about the effect the ending of the CGT exemption might have. It might be worth providing a focus for that by inviting pinsters to speculate about the segment of the market that classically has appealed to investors - 1 bed flats.

If there has been an artificial lift to prices it could have been most obvious in the prices of these properties. If so, will the price of 1 bedroom apartments under-perform from late 2014 onwards?
