We had to kill 10 days last March on the way home from FL so we could time our trip through NJ where our breeder is to collect our newest Lab puppy. We decided to check out St Simons Island and easily found a nice place. Nice area but our stay convinced us we wouldn’t want to move there permanently. We used VRBO to find a rental, but my wife owned a real estate firm for 30 years and we knew how to make sure the person we were dealing with was the actual owner. Otherwise I would suggest you deal with a real estate agency.
