Is it acceptable to list 'unemployed' as occupation when applying for a DTV eVisa for Muay Thai training in Thailand?

The individual is applying for a DTV eVisa under a Muay Thai course in Thailand, currently not employed. They are concerned whether listing their occupation as 'unemployed' might negatively affect their application, especially since they have rental income to declare. Commenters suggest alternatives like 'landlord' or 'freelance,' indicating that the occupation field may not significantly impact the application as long as financial requirements (like having 500k in the bank) are met.
