I'm currently renting a house that looks fabulous on first visit, it's really well laid out, high ceilings, attention to detail in lights, doors etc, but living in it it seems the architect and the actual builder where cut from very different cloth. Little things like no sealant around the bath, and big things like very poor sound insulation would make me very worried about what else was skimped on. It doesn't matter to me as it's just a temporary home but would make me very wary when buying of inconsistancies. Maybe I'm just cynical but I would see it as a sign that there would be constant problems with the house as it go older.
