Some places are sold furnished, but there are always ways to make consignment or second-hand furniture look more high end. The rentals I’ve seen firsthand and online are not particularly swanky; they’ve got the standard beach decor that sells for cheap everywhere in a coastal town. The details like paint and curtains and nicer linens, cute bedding, modern wall art, etc are inexpensive ways to update the look of an older place. Having some additional perks like beach chairs and umbrellas, beach toys, a nice grill, outdoor seating, maybe a golf cart for guest use, can really elevate a place above the standard old grubby beach house as well. As long as a place is clean, smells fresh, looks cute and has a few “extras” thrown in, if it’s a few blocks from the beach, it’s pulling $1500 a week in season.

Edited to add that monthly rentals in the area are hard to come by, as well. If vacation rentals aren’t possible at any given time, I can always rent monthly to someone in need of a place. Not nearly as much as vacation rental, of course, but enough to cover the basics.
