The big problem with this method _it will kill the property development market.
In my view they will apply taxation to the gross income of expats -a credit being applied for tax already paid .
Therefore expats can bring in as much money as they please -without being taxed.
This is my guess.
If the Thai tax authorities have any sense then a ceiling will apply-maybe maximum 60,000 Baht per tax year.
All the foregoing is pure speculation on my part -only time will tell
