N.D.
You live in White Lake but go to Holly schools? May I ask what part of White Lake you live in?
I am actually in Milford and I have not lived in a big city since I was 2! I love being out in a more country-like setting. It is really not that far to go to the store. White Lake should put you fairly close to M-59 which will take you just about anywhere, fairly conveniently.
I guess I might consider how close you are to friends and neighbors in your area, is your dog inside more than out, would it be cheaper to be in Livonia, how are the schools in both areas (Have you considered Huron Valley as school of choice?)?
Your children are still young enough that a move would not be too hard on them. I have no idea how Livonia schools are, or even Holly schools, but Huron Valley is pretty awesome.
I guess the best thing for you to do is really weigh the pros and cons of each city.
Hope this helps a little.
