I think Moondance's advice is the best. Right now, you've a roof over your head, no financial worries and a capacity to build up some savings. It mightn't be exactly where you want to live now, but your options will have changed in three or four years time (and posibly your circumstances). Why rush into something that has the potential to leave you a lot worse off financially, and still not be living where you want?
Remember: you can listen to all the opinions you like, but nobody has a 100% insight into what prices/interest rates/availability of 100% mortgages/rental market/stamp duty and other tax implications are going to be in a year's time, much less any longer time frame.
