I wouldn't necessarily want to buy a property next to a kindergarten or a school either
I actually have the kindergarten right on the other side of the street. Small, maybe 40 children, I have hardly ever noticed a car parked there (and I have been there at various times, it's still under construction) and the playing children are definitely not disturbing. When they are there, I'm at work, and when I retire, I will probably already have sufficiently poor hearing.
In front of my daughter's elementary school, the cars do pile up as well, but the properties were snapped up like nothing. It's all a matter of supply and demand...
