I'd have to believe that would only happen to the 1% crowd (the upper 1% of income). Only they would have enough "stuff" in their house that is valuable enough for someone to come back to *RISK* a second helping.
Also note that maybe 2 to 5 years ago, thieves would have taken flat-screen TV's. Not any more (because they're so cheap). A lot of what used to be hi-end home theater stuff is probably not being stolen any more.
Again, that s*it is a dime-a-dozen these days. Your average punk doesn't want to take something that he can't shove into his pockets or knap-sack.
Now, with regard to high-end cars - yes. It has happened lots of times where someone working at a high-end dealership tips off a crew as to where certain people live with their merc or benz or other high-end car, and they can also supply the theives with duplicate keys that they make when the car is in for servicing.
If I lived in the states, I'd have the address on file with any retailer (car dealer, credit card, bank, etc) point to a PO box (not my real house address). Same with my driver's license.
