What do I need to do to open a bank account in Thailand on a non-immigrant O visa and will my AirBNB landlord provide a TM30?

Airbnb, it is technically illegal to rent it out. But not to rent it. Most Condo’s strictly forbid it.

So if the lease of law forbid it you’re on a sticky wicket as far as your TM30. Far better a serviced apartment. It must be legit. One month wherever is ample time to find a condo to rent long term. The onus is on the supplier or landlord to complete the TM30 for you. The Banks have strict protocols for opening accounts. So you really need to have your ducks in a line here. Which is why for your first extension I’d strongly recommend an agent to take care of it all for you. Money well spent.

Please note that Airbnb stays of less than 30 days are illegal in Thailand, as a hotel licence is required.

You don't need to book a hotel for a week, one night will do to get a TM30 and you just need to check in and pay, no need to stay there when you have your TM30. The seasoning requirements for an extension is two (calendar) months, not 60 days by the way.

the letter for bank account from immigration costs about 500 baht

he should do one after 1 night,demanded it. go to immigration do your residency certificate and ask for a letter for the bank account

I would do what you suggest because 1 month will give you time to seek out a decent area to live.

There is nothing worse than signing a contract for 12 months then finding out you have a garage starting outside every morning at 7am, or soi dogs congregating outside your window.

Well, there are many worse things but you get the gist? 😁 To avoid that, get a pool facing condo if you're opting for a condo. High floor to avoid street noise and mozzies is also advisable as is not having your room opposite or next to the elevator or public stairwell

Can you tell I dont like being disturbed? 😅

You will need a certificate of residence from immigration.

To get this you need a print out of the TM30

Certificate of residence was a requirement for K bank!!

As per Thai law, any property whether a residence or business that accommodates a foreigner whether at a fee such as a rental property/hotel or private residence legally has to file a TM30 within 24 hours from your arrival. Many hosts don’t or can’t if they don’t have the proper rights on the property such as being the owner of the property or a proper lease that allows subleasing which isn’t really a thing in Thailand.

Best advice same as you already got in the other comment, check with the host beforehand if not book a hotel and ask the Hotel for a TM30. Any property legally has to provide a TM30 even if you only stay for one night. Again most hotels will not file this unless you ask them too especially on short stays.

Some older landlords are not familiar with the “newer” online TM30 system although it has already been around for a couple of years, back in the day they would have to go down to Immigration to file it with their Tabian Bans, Id and a copy of your passport. Now it takes less then two minutes online

When I know I'm going to need a TM30, and I plan on using an AirBNB, I always message the owner before I book. I ask them if they will do a TM30 for me. If they refuse, then I don't book that property and I keep looking for one that will.
