we have done it exactly as Alex Jiang states above. We do not have pensions at all, only investments derived income. I can assure you I am not an agent! Just a 50 year old Canadian happy to spend the next 10 years in beautiful Thailand. 😁. Good luck with your choice of visa. Luckily, there are quite a few to choose from, especially if you are over 50. Hopefully one suits your particular circumstances. The LTR suited ours, while the Elite and non-OA did not/ were more complicated, for us.
