What are the steps for applying for a retirement visa in Thailand while waiting for a house registration?

The user, along with their husband, is seeking guidance on applying for a retirement visa in Thailand. They have recently extended their stay, opened a bank account in Koh Samui, and are in the process of having a house built, which will not have its blue book until August 2023. Several comments suggest that they need to ensure they have the required funds in a Thai bank account, which should ideally be transferred from abroad. There is also discussion around the implications of not having a rental agreement and the challenges they might face without proper documentation. Participants in the discussion recommend using a visa agent and highlight the importance of meeting financial requirements and managing the TM30 registration process.
