Do I need a fully paid health insurance and a specific amount in my bank for a retirement visa in Thailand?

The user is applying for a retirement visa (NON-O) in Thailand and is inquiring about the requirement for a fully paid health insurance policy and the condition of maintaining 800,000 THB in a Thai bank account. They mention concerns about the expense of monthly wire transfers and the feasibility of withdrawing and depositing funds as an alternative. Comments clarify that the 800,000 THB must be held in a Thai bank account for a minimum of 2 months before application and 3 months after, reducing to 400,000 THB for the remainder of the year. Additionally, if applying for the O-A visa, a year-long health insurance policy is mandatory.
