@Margaret1031 Growing up on the East Coast, beach rentals were typically "Bring your own" or you could rent linens from the realtor. That is not the case anymore for hosts who are offering their properties on the OTAS. Linens are now expected/required and our homes should be guest ready.
You can purchase decent towels and linens from Sam's Club, Overstock.com and other bulk outlets. When making up the kitchen and bathrooms, leave only as many towel sets as you have registered guests. Do not leave a stocked linen closet, especially if your guests have access to a washer and dryer in your property. Expect to lose towels -- probably 1 for every 4 rentals. Have utilitarian kitchen towels; being on a golf course they are probably being grabbed to wipe off clubs and left in the golf bag.
I consider towels to be consumables -- as are the pillows, coffee cups and forks that walk away. I budget for their replacement.
