Orion Moreno's house
It is an unremarkable ranch style home surrounded by a broken down white picket fence, and has a fireplace, car port and two entrance doors.
Inside, the bed can be slept in without penalty, however most items inside are considered owned and will result in Karma lose if stolen. The interior is also identical to Doc Mitchell's house.
Orion Moreno's house only appears in Fallout: New Vegas.
