Anna is correct. You need to find out why there is no c/o. If this is new construction then the builder is responsible for completing the house, inspections and final c/o. Is this a foreclosure by any chance?
You have not provided enough information to give you a definitive answer. Contact me off line and we can talk. I work in Nassau and Queens Counties.
