A player who doesn’t own a house in Skyrim never really played the game to the extent that it should’ve been played – just about anyone would agree to that.
But as much as we love our cozy home that may or may not have a spouse and set of followers (in my case, both were present), it’s nearly impossible to reject a potential offer of a free home in a place as historically important as Raven Rock.
The Dragonborn DLC gives players the opportunity of obtaining a house for free here, provided you can earn the trust and respect of the people. But that doesn’t come from just co-curricular activities and minor philanthropic gestures; you’ll have to earn it by carrying out a certain set of quests.
The following are the quests that you must complete in order to get the house:
March of the Dead
You can begin the March of the Dead quest by going east of Raven Rock, to the Old Attius Farm. Do so by taking the main road, and you’ll spot an NPC being attacked by ash spawns. Help him, and you will start the quest.
The Final Descent
After having finished the March of the Dead Quest, it’s time to head into the Raven Rock mines. The Final Descent isn’t actually integral to obtaining the house, but is necessary in order to unlock the next side mission, Served Cold, which will give you the house.
You need to find Crescius Caerellius in the mine. Talk to him, and follow the quest-line till you come to the The Final Descent quest. It’s a relatively long quest, but it’s worth it, as you also find the second Dragon Aspect word over there.
The final quest for obtaining the house is Served Cold, and you’ll have it accessible after completing March of the Dead and The Final Descent. Speak to the Captain to initiate this quest.
Once you have completed all three quests, you will be given a new home in Raven Rock. Enjoy it!
