In my opinion, the sign of the market bottoming out will be when banks start offering 100% (or close to 100%) mortgages again. When this happens, this will mean that banks are confident that even if a buyer can’t pay their mortgage, the bank will be able to sell the repossessed house for the same amount that was borrowed and get their money back. This won’t happen for quite a while.
I personally reckon the prices have got a way to fall yet – it will be the redundancies that cause it – the market will get flooded with repossessed houses, and so the prices will be forced down.
I’m still waiting to buy my first house (have been for about a year and a half) – mortgage all agreed, just waiting for the crash – living with parents is shit, but better than losing approx 3k a month on the value of your house.
