If you're working in Thailand surely you would be on a Non B visa with the associated work permit and therefore the financial problems do not apply. However if you're working in contravention of your visa conditions then I would not be advertising it on a FB group.
as I understand it, uou cannot rent out a property for less than 30 days without a Hotel License under the Hotels Act. This primarily applies to condo buildings.
The Hotel Act, B.E. 2547 (2004), Section 15 states “No person shall operate a hotel business unless he has obtained a license issued by the Registrar. The application for and issuance of a license shall be in accordance with the rules and procedures prescribed by the Minister (8).”
There is an exemption for homes and villas (less than 4 units) and they must be registered with the Ministry of Tourism.
The Ministerial Regulations on the Types and Guidelines on Hotel Business Operation B.E. 2551 (2008), Chapter 1, Clause 1, it allows certain properties to be exempt from The Hotel Act, where it states: “Temporary accommodations which are established for commercial purposes for travelers or any person have less than four rooms in the buildings and less than twenty residents, a hotel license is exempted (9).”
Wise to Thai bank, the sender incurs the charges which are relatively small depending on the amount sent.
Having a Thai bank account, for a standard current account there are no fees other than the ATM card. There are ATM fees however if you don't use that bank's ATM or use it outside the area in which it was issued. These fees are small approx 15B.
