Present - "My new house is supposed to be haunted, but I so far haven't seen any ghosts."

Present - "She says here new house is supposed to be haunted, but so far she hasn't seen any ghosts."

Past - "My new house was supposed to be haunted, but until then I hadn't seen any ghosts."

Past - "She said her new house was supposed to be haunted, but until then she hadn't seen any ghosts."
