It is not that compulsory to have an attorney while buying any kind of property, If you know all the legal aspects of the papers the builder or reseller, in case of resale property, throws at your doorstep. In my opinion, you should prefer a lawyer who has decent knowledge in real estate and go through the website of Top New Jersey Lawyers | Moldovan Law Firm where it states what all necessary documents are required from the builder's side before selling that type of property.
