We bought a house in South Africa. The banks there required 6 months of bank statements (in country) and had a higher requirement for down payment. In our case, it was 50% down.
I would always consider currency swings between your home country and host country. We lost 30% in two years simply because of exchange fluctuations. GBPEUR may not be that big of a deal, but in other regions this is a major issue. I personally would not purchase a home in the US or Europe at the moment. Staying liquid is best given the current valuations.
