For what it's worth, the Vikings were very peaceable and property-respecting in Scandinavia - I'm sure we're all familiar with Saga-era Iceland's legal system, and the respect for property was substantial even in the culture (why was Burnt Njal's death so horrifying? because besides burning to death, it destroyed the farm). And even outside they weren't so bad; you can't raid a place too quickly if you raze it to the ground.
