Good morning all, Looking at a small two story property on Samui with land. House is already built, wife is Thai as our three kids are as well. We have a house upcountry, but the land was dirt cheap and the build was done by us with no plans. So not a newbie in the game but this marks a significant difference in purchase and price. As this is a bit of a different beast I have a few questions for those with experience. Thinking a a structural engineer inspection makes sense, what can one expect on costs for this, would they also survey the land to make sure the chanote matches the markers? Is there anything necessary to check that the house was built according to plan with the land office and there wouldnt be any issues? Anything extra you may need to look at regarding liens against a property? Is a title search necessary or would that show up at the land transfer office? Anything that I may be forgetting or missing? Much thanks in advance. -Stan
