What about holiday rentals, if like you say it's near the beach, why not rent the house out just for the holiday season,.
So many months rental, you can either do it yourself or join one of the many letting agents our there.
We have had many happy holidays by renting a full house by the owners, plus you have to leave a extra fee for damages so if it's bad at leased you have there deposit.
Lots to think about Sally I hope we have not given you a headache
