The title of your question and the details seem like 2 different questions. One of the reasons NJ’s property taxes are do high is because of the educational programs. I hear that many people move here specifically for the services available to autistic kids. Towns with better school programs generally have higher taxes. Property taxes also vary according to location… so the closer you are to NYC, the higher the taxes. The cleaner and safer the town is, the higher the taxes. If you want to know about ABA programs for autistic adults in the NYC metro area, the question header should indicate that. I do not know anything about those programs, so I can not give you advice there. Good luck to you and your son!
