I've been lurking on here for years and this site saved me from purchasing in the middle of 2007 just to get on the ladder. I've read all manner of posts since then, some predicting things which happened, some predicting things which never happened. However, I agree with @scottbeard in that everyones "circumstances" are different so the right time to buy will be different for people as well. Mrs KG and I have just bought a 1960's 3 bed detached bungalow in a secluded spot with some land with 25% deposit. The reasons being
1). Its near friends and family who live in the same village.
2). Its in a secluded plot with no neighbours to spy on our every move.
3). As its a bungalow we could knock out some internal walls and renovate it completely to how we wanted it.
4). There's enough land so in the future we can extend upwards/outwards if need be and be fairly self sufficient with vegetables etc.
5). Due to the above, theoretically we do not need to move again so are effectively out of the market.
6). Its well built and not a small new build on an estate.
We love our house and if i'd been sticking to the "we're not buying until prices drop 30% or more mantra" then we would have passed over this opportunity and still been living in our old pokey flat. However, if we'd have to obtained a 95-100% mortgage then I would have thought about it hard but our "circumstances" meant that we could do it. You do not want to be so engrained in 1 way of thinking that you become blinkered.
I'm open to abuse
