Which cities in Germany are the most expensive and cheapest to live in?

And also, which cities in Germany are the safest?

1. Cheapest: Berlin and maybe Bremen. expensive: Munich, Hamburg. Safest? Not sure...I feel really safe in Berlin, but now and again there is crime. Places where people have good jobs should have the least crime. Old east German regions have the highest unemployment rate, and Berlin is the poorest city, so crime might reflect this situation by being worse.

3. I don't know why people say Bremen and Berlin, it's simply not true. The eastern cities, particularly the smaller ones, are least expensive. Leipzig and Magdeburg come to mind, in terms of larger cities that are cheap, slightly smaller but still cheap are Halle, Chemnitz, Cottbus and smaller still are Zwickau, Gera, Zittau. As far as crime goes, I have found that Germany has low violent crime but high amounts of graffitti in poor areas. One of the reason why some areas are cheaper than others is the lack of employment. Dresden is not on the list, even though you may still find some bargains in real estate, as its economy has improved and has still greater prospects. Leipzig also has some good prospects, with a very well respected, large and old University and two recently build auto factories (BMW and Porsche) recently built on the outskirts of the city. One quite small city that I found quite charming was Altenburg. It's buildings are not new, not ruins in most cases, but not restored either. Low graffitti, friendly people, and easy to get to from London via RyanAir. And it is mentioned because it is safe and cheap. It doesn't have much of a nightlife though. If you want nightlife, Hamburg, Berlin are pretty good. But there's also crime. Leipzig is a good mix of cheap with nightlife and relatively low crime.
