What documents are needed to extend a non-immigrant visa in Thailand and is a lease required?

A report from a visit to the Pattaya immigration office regarding the extension of a non-immigrant visa noted the acquisition of a TM30 receipt without any issues. The individual received a list of required documents, although there were conflicting messages from staff regarding the necessity and duration of the lease required, as one indicated a 12-month lease while another suggested a 6-month lease. Additionally, they clarified that a receipt for one month in a hotel was insufficient.
