@Mark5438 Contrary to what was written by the other responder, this absolutely sounds like a SCAM!! Run away quickly!
AirBnB does not do any pre-viewing. There is no deposit other than when you make a reservation and make a payment. That's just a payment towards your reservation and not a deposit. This is a SCAM!!
Don't do it!!!!
Because you said "the owner said it's through AirBnB" it sounds like your inquiry was not done through AirBnB, but from another website, like Craig's List or similar. It's a scam. Don't pay any money!!
