What are the requirements and best places to apply for a retirement visa in Thailand?

Hello all.

I'm planning for a retirement visa when I reach 50 in a few years time. And I'm planning to find a place that I can stay without headache when come to the 90 days reporting and tone for renewal.

1) need to have ฿800k in bank

2) TM30 address to be submitted for the application

3) application before arriving in Thailand or apply when reach Thailand.

4) place to stay and easy to report for 90 days and or apply for renewal is ( any recommendations beside this few place)

1) Pattaya

2) Hua Hin

3) Bangkok?

4) hatyai

5) nongkhal

6) udon thain

To my understanding that if my landlord can summit the TM30 it can be any type of place to stay right

I'm from Singapore been in and out of Thailand under 30 days tourist stamp and use hatyai to exit and reentry for other 30 days tourist stamp. I'm a bit tired moving in and out every 30 days

Admin please delete if this is against the rules

Thank you.

Please advise.
