Im currently looking into this. I guess it comes down to a number of factors:
1. Location ( if a foreigner can a foreigner legally own the building / land?)
2. Cost - is it more cost effective to lease on a long term lease as oppose to own ? Do you have the capital upfront? If in a different country foreigners must have the cash upfront to pay.
3. Cashflow - will buying cause you not to have cashflow in the vital first 6 months to a year?
Im sure there are other considerations but thats just what comes to mind at present
