I'm trying to get to Thailand on the DTV but I'm having issues finding somewhere reputable for me to take a soft power course. Any help?

Hello, I am seeking expert advice on relocating my family to Thailand in June 2026. My children will be 17, 14, and 13 years old, and I am unsure about the specific visa requirements. Chat GPT suggested that the DTV would be the most suitable option for us. I plan to homeschool my children initially and later explore other educational options. As a remote federal employee, I anticipate continuing in my role abroad, but I am also exploring alternative employment opportunities. I am currently pursuing TEFL and Cybersecurity certifications. Although I do not have substantial savings, I expect to receive $100,000 to $150,000 from the sale of my house and additional funds from selling our belongings. However, I am concerned about meeting the income and asset requirements, particularly if the necessary funds are not available in my account at the time of application. I wont be able to sell my house till around March when it is closer to the time we leave. The price for a monthly rental here in PA will run us at least $5000 which is a lot so if i can stay here as long as possible I will. Can someone explain the financial guidelines to me? Will my current job count as income or my house as assets? Can anyone recommend a professional in Pennsylvania who can assist me with the visa application process? Hopefully I am making sense. Thanks in advance!
