Don't do it. It's easy to get stuck with something you don't want.
I've owned two houses in the UK; the first one turned out to have horrible neighbours and took a while to sell (until the right people saw it - it was the right size for them, decent house, and the people who bought it were thicker skinned than me!).
The second one.. I still own, despite living in Canada. I moved in with my wife-to-be in 2008. Ah, 2008.
Now, I rented it out pretty quickly, and (touch wood) been mostly lucky with tenants (it's managed - again, I live in Canada), but it is not "convenient", and I have to pick a time to sell - because it's hassle trying to sell when you have a tenant (can only have viewings in the last 2 months of tenancy), and obviously if it's empty you're not making any money!
Just... don't do it. Find something cheaper to rent, shove the rest into a savings account (you won't lose much to inflation in 2 years!).
UNLESS you want to keep it as a rental. In which case - buy a place you'd have no trouble letting out, rather than your own perfect home!
TL;DR: RENT!
