I know some of you have encountered this bug; that is being unable to purchase the house in Markarth. I know there are a few "fixes" though they do not actually address the bug.

My situation (as well as a few others) is that I have completed all relevant quests, I am level 28 and have already had the option open with Raerek the Steward to buy the property, however when I had enough gold and returned to speak with him I was not able to begin a dialogue, save once a day or so to give me a bounty.

SO, has anyone figured out how to fix this yet? Cheers folks.
