There's a massive difference between active management (e.g. short let luxury rentals) of a property vs passive management, though. If they were renting out properties long term, the yield would be lower. I have a friend who did something similar in London, and he was renting out apartments for £200-300 a night which would rent out for £3,000-3,500 on a long let lease. Also, I would assume the average property worth $6m would rent out for a lot less than $25k a mo. Most properties worth $6m can't even be rented out consistently, for years on end unless you're in a prime city such as London or NYC. Santorini is a great place for wealthy people to spend a week, or even a month, but I don't expect many to have their permanent base there.
