Not going to crash, they have leveled I think.
Buying, even if it's a flat has to be better than renting a) foot on the ladder and b) your are buying something, when you sell it on you will get that money back hopefully.
I think the slight drop is down to the fact that estate agents were uping and uping the prices of houses while the market was rising, as it slowed they kept upping so they became overpriced, so properties were sitting on the market for to long and would then be price dropped or a lower offer accepted.
To keep things moving estate agents have started advertise houses at a figure that reflects the market to get them shifted more quickly.
Round my way a coul,e of years ago a 3 bedroomed place was around £135K, now they are up for £127K.
Keep in mind it isn't what the properties are advertised for, it is what they are actually selling for!
A friend of mine viewed a place up for £118K, he put in an offer of £100K and was laughed out of the estate agents, but asked them to put the offer in. He recieved a call saying the offer was rejected.
He popped round the the property that night and introduced himself to the seller who had heard nothing of an offer

between them they agreed at £102K.
The estate agent was mega pissed off, but was quickly reminded that they had not put the offer in as they should, yet had claimed to have so buttoned their lips.
Buggers!!
