A number of years ago (probably 6-8 years or so) a friend and his partner were on a show like that -- I think it was a Home & Garden Channel show about people buying second homes. The episode followed them through several Palm Springs homes they were "considering". In reality (as opposed to "reality", I suppose) they were already under contract to purchase the house they "decided" on at the end of the episode. They were also urged to find some features of the house to pretend to disagree about to add an element of tension or drama. "But won't the glass wall in the master bedroom be inconvenient when your mother comes to visit?"
