Sunken beach house

There are two accessible Sunken Beach Houses found in the Blue Paradise Vacation Rentals area, which are surrounded by a number of Lakelurks. Only two of the three grouped houses are accessible, the house farthest northwest and the center house.

Center house
The center of three homes has a two accessible doors leading into and out of the house. While the surrounding area's water is not radioactive, the water inside the home is mildly so (+1). It should be noted that drinking the water will not give you radiation.

Items found inside include a BB gun (Fallout: New Vegas), a Pilot light and two Brahmin steak (Fallout: New Vegas) inside an oven, a Sunset Sarsaparilla star bottle cap and a few regular bottle caps near a refrigerator, plus a couple of misc. items of no real value.

Northwestern house
The more northwestern house has a single door that is only accessible under water. Like the center house, the water inside is mildly radioactive but drinking it doesn't give you radiation. It appears to contain only a few misc. items of no real value.
