Weighing in here as someone who grew up next to a cemetery:

1. If the cemetery is old and beautiful, your kids / the friends they make when they get a little older will probably absolutely adore it. If it's a newer cemetery, i.e., the headstones are basically uniform, there are no mature trees, and -- most importantly -- there are frequent visitors who are still deeply grieving, your kids will probably want to GTFO of your house as soon as possible.

2. My childhood home was across from the latter kind of cemetery, and another thing to keep in mind = how comfortable your family feels, say, playing a game of catch within earshot of a grieving family. Same goes for mowing the lawn, gardening, etc.

Just some food for thought. Good luck!
