jon c,

The costs to build are not necessarily higher, the labour costs can make up for any higher costs of materials and finishing. The real problem is when the owner does not do their "homework" and ends up spending much more for materials and labour. I have seen many foreigners receive incredible information from credible local contractors and even other successful foreigners here, only to see them ignore that excellent advice. The owner can end up paying triple the cost for not following that assistance. Do your homework and please listen to others who know the business or have been there before and have been successful.
