It seems that in Oblivion it is harder to earn money as a Thief than in other TES games. Every house I break into has minimal loot and I struggle to earn money without clearing a cave, which defeats my purpose of playing as an unaggresive merchant/thief.

How about you guys? I've been playing Oblivion for years and for some reason I can't seem to make stealing work as far as coin goes.

Any ideas?
