Just whack 400,000 in immediately you have your account set up. Then you have 9 months to top it up to the 800,000 required for retirement "extension" or if "marriage extension" you have the 400,000 in their already 😁
Or if you want to use an agent again then the cost for them to 'fast track' you as you have the money in situ the couple of months before. Which I think is around 7,000 baht
Or the monthly income road, bit more paper work but still doable

Nothing to stop you putting your money in a Thai bank after you use an agent, if you did not have it in before and then doing your own visa when it comes to renewal.
I do not have any particular concern, merely mentioning the fact that one, depending on the immigration office, is required to submit a completed TM 30 upon returning to Thailand.
Use an agent, many around that will do it, and you do not even have to leave your province. Will involve a wee journey to a post office to use the EMS system.
The cost of travelling and staying in Bangkok from Isaan a couple of times, usually works out more expensive than posting to an agent and their fees.
