Searching for any room, garage, closet, shed to live in May-August

Second year lifeguard in search of any inhabitable living space from May to August. Couch or closet I just need a place to sleep at night. I’m clean, quiet and away from the house most of the day working. Willing to pay up to 850 and the closer to 30A the better. Not opposed to Niceville/ Freeport and or Destin area.

Any help with leads is appreciated 🙂.
