I was gonna post this, SOOO many of my neighboors have had eastern europeans break into their houses, they've always avoided my house because of my german shepherd.
The organized breaking in is also happening a lot in the Netherlands as well.
This happened to a friend of mine :
His apartment and the apartment of his neighbors share a common stairs and are grouped as 1 house.
All 3 apartments where complete stripped from electrical appliances such as computers, televisions, radio's, furniture, microwave and similar material as the OP describes. Important detail is that a truck was parked that day in front of the house that seemed like a truck from a moving company, it was rumored that the burglars where even wearing overalls with a company logo.
We suspected that the apartments had been scoped out prior to the event as to see when the working people would leave. Then the burglars would enter but because they looked like they were a moving company, people passing by did not expected anything wrong because they did not seem suspicious.
Further more, we pay with a magnet strip before and now with chip and a lot of automated paying systems have been hacked.
Letters with paying notifications to banks are being intercepted and bank account numbers are modified.
All eastern European criminal gangs.
