here's my tuppence worth to add fuel to the fire... ruled by the head - by all means do sums and think of things as an investment etc. However, the reality is most people want somewhere nice to live and this 'wait a few years' thing is really a bit much ... if you already own your house then fine, but I think for those who don't and just want somewhere to live - being ruled by the heart is as valid too - I know people will instantly disagree but life isn't all about money (most seem to think it is). You can live your life by savings and deals and offers and rates but none of it will make you happier
Simply put - if you like the house, like the area and feel that the price you pay TODAY is fair, then why should there be a problem. Yes prices might go down and if you had to sell in 12 or 24 months I'd be worried. But if its your family home for a while then who knows - and as no one is a fortune teller you can only be ruled by what you feel today. As a previous poster said, in a few years or months time, who knows what the credit avail. will be like or if the house you want will be available - so if you have the cash and like the house I say good luck and have a happy home
