Hiya
Yep the one way which is ASSURED you can buy is just like almost everything else in modern life - Money.
If you have a 'sizeable' amount of dosh, you can buy anything. It's almost as easy as that!
E.g the other way around for me. I want to buy a place in the USA. I'm not American, have no credit there, no history there whatsoever so am like you in that respect over here. However, I've spoken to a few mortgage specialists, property people etc and if i was for instance to drop a 30% deposit on a property, I can pretty much be assured I'll get a 70% mortgage. The fact I have no credit, history or standing within the US magically then becomes 'glossed over' !!
It's the same here too, to buy here that way means 'just getting a 20-30% deposit, a mortgage then will be available to you!
The next step out of all that is to raid yer piggy banks and see if you have enough!
there are other elements of course, what I've mentioned is basically a Buy to Let mortgage here, so I'm unsure if you could 'arrange' one of those and live in it yourself or if you can get a normal mortgage by placing a large deposit and living in the property yourself
I know you'll be looking through the Yellow pages at 'Mortgage advisors' in the near future!
good luck !
