You can get a spacious penthouse sea view condo with your own pool and probably even your own direct lift stop for less . Probably even a full-time maid and strong security.

When an agent or owner refuses to provide what is needed to do a TM30, it typically suggests that they are not reporting the rental income to avoid paying taxes. This has been the case for many years.
But now, at least at Jomtien immigration, a TM30 filed after your most recent re-entry is required to do just about anything. So if your landlord is not giving you what you need to do a TM30, it could be a big problem for you, I think.
