Lot Challenges/Lot Traits - How do you use yours?

I also tend to assign lot traits by whom will be living there. If there will be children (if not already) I assign the Child's Play Trait. If I have an aspiring Chef, the trait that would make skilling in this aspiration easier. Just for fun, I moved in a family in HoB to a lot that had the Wild Foxes Trait. I quickly learned to remove that one. I am currently playing a Rock Star, so I give his lot the Good Acoustics Trait. And so forth and so on.
