WhatMakesYouHappy - I don't think that posting about house prices falling is "posting inflammatory messages" - I am careful to post links to sources of what I say, and while you may dislike house prices falling, for example if you recently bought an expensive house, it could hardly be called "inflammatory" to suggest that this is indeed happening in London and the SE.
Just because you personally don't like the news, it does not make it biased. I am baffled as to why you think that the Daily Mail, the Guardian, the Independent, the FT and the other newspapers I have linked to are all likely to suffer from "an inherent bias" in favour of reporting falling house prices. They cover the whole political spectrum and include the most respected voices on economic affairs. What evidence do you have that they are all, collectively, lying about the direction of house prices in London and the SE?? 
What they are doing is reporting data from various organisations, such as Nationwide, the Halifax, the ONS, Rightmove, RICS etc, which have been used to measure house prices rising and falling for many years.
But if you have other data that prove that all these newspapers are in on some secret conspiracy to bring down house prices and that on the contrary house prices are really rising in London and the SE, contrary to every single piece of published evidence in recent months, then please feel free to post away below.
