Those don’t even look like anything special. And the location is amazing but also probably $$$$ to insure.
If I’m spending the equivalent of the price of a whole damn house in rent per year I better at least have the kind of house where you host all the family holidays.
My parents live on the beach in Florida and need to pay $15k every few years for sand restoration. The sand erodes from the beach and they need to pump it from the middle of the ocean back to the beach. Also, all of their cars and outdoor things (windows, door knobs, outdoor furniture) gets ruined from the salt air.
