We use door hangers/bandit signs to advertise our resident refferal. We also give a $500 check to the resident. This is the only apartment community that I have worked at that actually gives a check and receives resident referals. It is trully amazing what money will do. Also keep in mind if you have a good community, maintenance team, onsite team, and resident events they will refer their friends and family.People love to show off where they live and live close to friends.
