Property rental is another whole topic. If you are renting in a resort/tower/block from a company, and they have an online govt account (most should), then when you sign a lease or long-stay, they should file a TM 10 online. You should report to the immi office within 30 days, but it's a formality, they just check on the system. When you next do annual renewal, you need to bring copies of the property ownership records (Blue Book, etc.), but the company should be well-organized, well-documented and familiar with the procedure. The problem is private landlords. They do not have online account, and you together, will have to file paper TM 10 at the immi office. You will need Blue Book etc, but there may be a chain of ownerships of the property, mixing Thai individuals, Thai companies, and farangs who want to hide their identity or stake (more than 49% ownership by farangs is illegal). Then it can be almost impossible to get the right docs. You cannot stay hotel, temporary boarding, or AirBnB for a long-term visa.
