Hi Sussi, if you are wanting a horse, you will have to focus on areas outside of Charlotte proper, as one cannot own a horse inside the city limits and there is simply not the land required to properly board a horse. Some great equestrian communities are Weddington & Waxhaw in Union Co, as well as Ft Mill/Indian Land in SC. You will find many opportunities to either have enough land to board your own horses, or a number of excellent facilities nearby. The schools are highly-rated as well. As far as nursery rates, are you asking about the cost per week or are you asking about their ratings? Both, of course, vary by locale and facility, but you will have no problem finding one that fits your family's needs, as well as budget.

Good luck with your move - you and your family will love it here! Kathleen Turner, ABR, CRS, ePro
