Why is Elvis surprised to see where Angela Rossi lives?

Haig tells Elvis to go see where Rossi lives, suggesting something unusual about her home. Rossi lives in an expensive neighborhood in Los Angeles. She lives in an apartment in Marina del Rey, which is home to expensive mansions and apartments. Elvis thinks these living accommodations are too expensive for a police officer. He runs a check on the apartment to see who the owner of record is. After talking to a neighbor, he finds out that Rossi has lived in the apartment for two years and she has two children. Cole is unable to get more information other than she is the owner of record.
