Is it expensive to immigrate to Thailand? How much does it cost?

Thailand can't immigrate, can it? I consulted when I bought a house in Thailand before, and the agent clearly told me that Thailand could not immigrate. Actually, I don't want to immigrate to Thailand. I just want to invest there and go on holiday occasionally. Thailand's housing price is not particularly cheap, but it costs 20,000 to 30,000 yuan, but it is acceptable without a swimming pool or fine decoration. The key is to be optimistic about the future value-added space.
