Yup. They all live in nice towns that are near really nice towns. I can't imagine someone making Waller $$$ choosing to live on Staten Island, different strokes I guess, but, seriously, Staten Island? Did you see the 2 garage set up at Kay's house? Weird.
Where Kay lives comes closest to being a noteworthy place, but even still, it's not Buck's County or the Main Line. Ram's place lists for that much because it's so close to NYC. To put it into a regional perspective, a decent 2 bedroom place in Manhattan will run you at least what Kay's place is valued at.
