I'd say 500k is around average, your going to have some with a couple million and then a little more with 10+ million. Your offer of 1-3 million is a little overboard. Also the really wealthy prob won't post their amounts and you won't really get an accurate avg due to some not visiting the forums! and fewer responding to your post. They will sit on their Gil mountains and possibly increase personal housing costs lol since SE doesn't want someone to buy an entire ward lol.
