How much does it cost to live in Thailand per month. For retirement?

It wont be expensive because Thailand has low taxes which is good =], i only know how much a one bedroom apartment is in Bangkok and its probably 3,099 baht which is $100. and the food, doctors, hospital, dentists for a month is 92,995 which is $3000 and the visa is pretty expensive and its 154,992 baht which is $5000! and for a rented car it will be 9,299 baht which is $300 for a 5 seater car =] hope i helped :)
