Add up
all the numbers, and figure out what the total cost to purchase the property will be. Beware the clauses.
Then:
-guestimate deductable interest vs
otential earnings,
-guestimate what the cost-of-living index(i.e. inflation to pay off foreign debt) will be 30 years from now,
-guestimate the local political atmosphere(i.e. future buyer draw),
-then get back to us.
