Well I've just looked at Zoopla and Rightmove for my part of SW London and I am honestly
at the price of 2 bed houses in my area. Some are STC and some are (IMO) just dreaming and chancing their arm.
I'm not sure Roneik there is going to be a crash for London, more like a small downturn. It just seems like madness that people are paying so much for 2 bed homes (I think they are thinking of adding the loft to make it more of a family home as 3 beds are seriously out of reach for most - us included!)
We're at a time where people with family's want to be in London, want to be closer to work and not have to schlep in on commuter trains. I'm sure this will change, as things usually do, and until that sentiment shifts London I think will bear up OK.
But what will happen is there will be a downturn, then those on forums like housepricecrash.co.uk who have all their money saved in their mattresses will buy, and the cycle will start again. When there's demand prices will always rise (or stay level).
Of course those on HPC say they don't want to be a slave to the banks with mortgages etc, but more than a few just seem bitter (understandable) about how high prices are at the moment and the second they come down won't have a problem being a 'debt slave'.
