This is second hand information, so I can't be certain that it's true, but supposedly the innkeeper of the Inn of Ill omen (on the way from imperial City to Bravil) has such a low responsibility rating that he will buy stolen goods from anyone. The problem is that he has almost no gold, so you'll need to first invest in his store before you can start using him as a fence and that requires your Mercantile to be 75 or higher.
You're right. I knew there was a "passive" fence out there somewhere, but I forgot who he was. He's Mannheim Maulhand, publican of the Inn of Ill Omen.
As with any vendor, fortify your Mercantile skill to 75 or higher, and you'll be allowed to invest in his shop for higher max $ per item. Not like it really matters with stolen goods... it's a crap enterprise over the long haul. The best you can typically steal from anywhere is silver dinnerware, fine wine and fancy clothes. You get better returns by raiding bandits.
Again, thank you :bowdown:
No problem.
