Any owner/landlord here?

Want to ask a question, me and my wife is considering renting a place in TR Residence. We talked to someone not sure if owner or agent about viewing a unit and he is asking us a RM200 refundable application fee before viewing and if we are not interested we will be refunded immediately.

We agreed but we told him we will pay him on the day of viewing (means cash) as we are not comfortable banking in/transferring money to someone we haven't met yet (sound scam if you ask me)

This is the first time I have encountered something like this paying RM200 to view a unit you are planning to rent out
