Last time I was in Thailand (nearly 10 years ago now) I was led to believe that only Thai national could own real estate property. Even if an ex-pat married a Thai national woman, that was not enough to enable them to own real estate.

The big enticement of working in Thailand was the (relatively) low tax rate (top bracket was 30%) and the ATO-Thailand tax treaty. I ended up with low-income support from ATO that year.

But I could be wrong and/or things could have changed since then.
