The best years to do Singapore would have been back when SQ was offering expat terms. Retire from BA at 55 years old as a B744 Captain, rent out the house in the UK and send the money along with the pension income to a competent financial manager in the Channel Islands/Isle of Man. Come to Singapore for 5 years on the full package and enjoy the expat lifestyle while stashing away the surplus income. Retire at 60 and return to home country well cashed up and enjoy life.
