Besides your curiosity regarding Meadowbrook Village, which will be answered no doubt by a New Jersey Realtor, you are asking questions that are always important to buyers. But issues of safety and resale are in the eye of the beholder, how safe is safe? What is a good resale? To determine safety, call the Plainfield Police, and tell them you want to know about that area--do your homework. Ask them if they have many calls from that area, are there people living nearby who would be an issue for you and your family if you were to buy. They will tell you things that a Realtor would never know nor be able to disclose.
Good luck with your purchase.
