Do I need an agent to sell, or can I sell privately and save the 2%?

You aren't legally required to use an agent, but only RERA-licensed brokers can obtain the Trakheesi permit needed to advertise on Bayut, Property Finder or dubizzle, so pure private listing is difficult. Agents charge about 2% + 5% VAT and handle pricing, viewings, buyer-vetting and transfer paperwork. You can sell privately to a known buyer and simply meet at the DLD trustee to transfer.
