Meh - not too bad based on above. I.e you'll survive OK
The question is - what is your premium on going expat? How much extra free cash flow a year over staying at home do you need? 500 US a month? 5000 US a month? 50 US a month? Everyone will have a differing level. For me it is about 40%, but I enjoy living abroad.
Other thing - free housing can be a mixed blessing. If you don't have the financial discipline to save what you would otherwise would have paid for mortgage repayments, you will end up saving less (mortgages are a good way of forcing people to save, who otherwise wouldn't...) Especially if property prices "at home" are going up.
