In my current campaign, I convert old dungeon modules. I throw three hooks to the players, making sure each adventure is different, and see what they grab. This campaign, the very first hook they grabbed was an old keep for sale at a ridiculously low price (1000 GP). This is a second level party that REALLY wants the money sink of an old keep.
PCs will always have something to spend money on. The fact that it's no longer in pursuit of an endless stream of +1s is a good thing, not a bad.
Cool. I'm using Castle Caldwell in my campaign too. The party has been asked by a young noble who recently purchased it to find out why he hasn't heard from any of the servants & men at arms that he sent to assess and start cleaning it. It might have something to do with the Iron Ring slaving operation in the dungeon.
