If I as FO could cash (living in Sweden) about SEK 30,000 after all social taxes and income tax is paid, that equals a salary of 45,000 on a "normal" payslip. That is a very good salary in Sweden. I am very happy with that.
Deduct holiday (10-20%), commuting to BKK, hotel, taxi, LOL and then take into consideration that a first hand renting contract of an apartment takes 10-15 years of waiting or buying a black market one for €35k and things will not be as attractive.
Forget about getting an apartment mortgage on a dodgy contract.
If you are going to deduct expenses you have to be either employed there or set up your own business in Sweden. In either case you can forget about around 65-75% of what norwegian will pay you. Also watch out for tax evasion in Thailand. I do not recommend getting in trouble there as an expat. The prisons are not of a Scandi-standard
Don't be blue eyed and be very careful with what you sign.
