Yup like many others here all I have to say about Kaiser is "GODDAMN for 35 you are one attractive looking man" and no I'd totally go homo for him xP (I mean.. i swing both ways but even if I didn't....)
It depends on what it was before. If it was always an house, then yeah, it's weird. A 3 story house could have easily been a shop before, with the actual shop on the ground floor, 2 bedrooms on the first floor (for the live in employees) and 2 on the second floor (for the owner and maybe his child)
