What are the steps and requirements for obtaining a retirement visa in Hua Hin, Thailand?

Thought I would share my visa journey at Hua Hin immigration (retirement)

1) I already had a Thai bank account so I made sure I moved over the 800K

2) i obtained a tourist eVisa in my home country. I should have gotten a non O but I thought it had an insurance requirement (US) but they recently dropped this to align with all the other consulates around the world.

3) entered Thailand on the SETV

4) got all the bank paperwork and house owners info and applied for a Non O. Went back 2 weeks later for stamping of the 90 days.

5) 45 days later I went to get the yearly extension for 1900 baht and a reentry permit for 1000 baht. I didn’t have a tm30 because my new landlord would not do it. I was worried about it but the immigration officer didn’t seem to care and I think she did it for me. She stapled a ‘Receipt of notification’ in my passport which I think was proof of my new address.

I did change addresses between steps 4 and 5 which I thought would cause confusion but it didn’t.
