What are the requirements for opening a bank account in Thailand as an expat with a visa?

The user is a foreigner who purchased a condo in Thailand and needs to open a bank account for related payments. They are traveling on a 30/60-day visa and are inquiring about the necessary documents and if a special visa is required to open a bank account. Community responses indicate that it may be difficult to open a bank account on a visa exemption. Those over 50 may find it easier by applying for a Non-O visa in advance.
