How Do You Decide Where To Live?

I usually come at it from the opposite approach: whenever a new pack is released, I think about what I want to do with that world, in terms of both community lots and in terms of the families that I might want to add there. Then once I've created those families, they go right into the rotation with my existing households. 

However, once in a blue moon, I'll get an idea for a household outside of the pack releases, and then I think of it in terms of what their lifestyle is: careers, hobbies, family structure/social needs, etc. If they are single, do they want to meet other singles? If they have kids, do they want to make friends in the neighborhood? Are they supernaturals? Are they outdoorsy? What kind of scenery or style of architecture would they prefer? Then I browse through all of my available lots in all of my worlds to find the best match.
