That surprises me. You could just pick a random home in the right area and hit the jackpot every time.Doing your burglaries in the right area is impotent, but for what I can gather from reading the newspapers professional burglars also looks at other things to maximize their profit.
For example in an area you can have to houses that looks the same, but one is own by a couple that is old and not that rich. They do have the money to live there, but barely so they don't spend that much. In the other house you have someone that is younger and just got rich. They will be more likely to have movable objects like jewelry, Loui Vuitton handbags and a new TV one can steal.
The local junkies are of course just breaking into random apartments, but a lot of the burglaries her is done by professorial teems. They want to know what to expect when burglarizing someone.
