Can I buy all plots of land on skyrim

The wood needed in the Hearthfire DLC is distinct from the wood you can obtain from any chopping block. You are looking for Sawn Logs. These can be purchased from several log merchants in the game:

• Aeri - Anga's Mill in the Pale
• Bolund - The wood mill in Falkreath
• Gilfre - Mixwater Mill in Eastmarch
• Grosta - Heartwood Mill in the Rift
• Hert - Half-Moon Mill in Falkreath
• Hod - Wood mill in Riverwood
• Kharag gro-Shurkul - Solitude Sawmill in Haafingar
• Thonnir - Wood mill in Morthal

Some of these merchants will also allow you to chop lumber from free if you complete enough radiant quests to raise their disposition. Note that if you saw your own logs, the merchant must be nearby for you to actually receive the lumber.

After doing some digging:

It turns out the glitch is caused by completing the Dark Brotherhood quest - Kill Helvard.

Apparently, the Jarl of Falkreath knows you killed Helvard (even if you are sneaky about it). In fact, I killed Helvard when he was taking a nap, so Helvard certainly didn't see it coming.

Anyway, after killing the Jarl's housecarl, Siddgeir's disposition is lowered significantly. Since I am already Thane in Falkreath, there is no way to raise his disposition, unless I was playing the game on PC.

However, I fortunately found a solution! If you have NOT completed any of the Legion/Stormcloak quests, then make sure to do the following:

• Side with the Stormcloaks so Dengeir replaces Siddgeir as Jarl.
• Talk with Jarl Dengeir (he will ask you to become Thane again)
• Talk with Tekla, the newly appointed steward, and she will give you the option to buy land

I really hope this helps someone in the future!
