I don't know if this will help you, but it fixed my problem with the Jarl not giving me the option to buy land.
*Copied from another thread*
Hey Op, here's some help for you, I had the same problem, I did all the quests I could think of, and helped everyone in everyway. (Spent the last 12 hours doing so) Then I found this out....
-Note that the starting quest for the Jarl to obtain a drink is a "radiant" quest that cannot be started if the Dragonborn is already on one of the following quests:Hey Op, here's some help for you, I had the same problem, I did all the quests I could think of, and helped everyone in everyway.

-Note that the starting quest for the Jarl to obtain a drink is a "radiant" quest that cannot be started if the Dragonborn is already on one of the following quests:
- Getting the book The Mirror for captain Aldis in Solitude
- Getting a Mammoth Tusk for Ysolda in Whiterun
- Getting the book Song of the Alchemists for Lami in Morthal
- Getting the book Night falls on Sentinel for Rustleif in Dawnstar
- Getting an Amulet of Arkay for Torbjorn Shatter-Shield in Windhelm
You CANNOT become Thane if one of these quests are currently active. You must complete any and all of these quests in order to get the Jarl to give you the radiant quest to begin getting land. Once I finished all of these quests, I was given the right quests from the Jarl to purchase land. And it only took 12 hours to figure it out...
Why, in God's name... Would they make getting a book for the Alchemist in Morthal, make you ineligible for Thaneship? NO one without the Internet would have figured that out, well, at least not me.
