They are the middle man. No fees they say, but if they are paying you one price and listing your property at a higher price and pocketing the rest of the money, that constitutes fees.

Hire a licensed NJ Realtor and save yourself from allowing an unlicensed person from making a profit from your property. They did not want to take the time to go to Real Estate school and take the exam in order to do things the right way. They want easy money with little effort.
