While I have not done it I have read several times that it is possible. People do it both ways. I read you just change your reason at the renewal. Instead of retirement it’s marriage to Thai.
you have to go to Muang Thong Thani immigration office in BKK. Go to the 2nd floor and report your address there. If you do it yourself you fill out a TM47 and the receipt is the bottom of the page
You need a lease. Be sure that the lease includes the documents proving the person renting to you on the lease is the owner of the condo (not good at remembering the names of these things). But one looked like a deed to a house with the floor plan. Also the owners ID card copy. If they are used to renting to foreigners they should (are supposed to) do it for you. Make sure you get the receipt.
If you have to do it yourself you need those documents.
Bangkok Bank on 2nd road in Pattaya. Very close to Soi 6. I opened mine there with my passport, 90 day visa and a smile. No work permit. No letter from the embassy. Nothing.
What we found was the mall branches were most difficult.
