Depends on lifestyle. but i also think 1.2k can be done.

The hidden cost like surprise hospitalisation bills will bankrupt many who are unprepared

Can be done with 1.2k. just need to really meal plan etc, and rental of room with no attached toilet. some rooms in kranji only $550 a mth. meal plans could be a loaf of bread with ham for all days of the week
