Is there any form of housing beyond inns and the "Personal Chest"? I haven't gotten too far (they've just sent me to wipe some guard's memory) so I may simply not have reached it yet, but I would quite like so form of "Home Base", if you will.

Hi.
Do not believe this is a spoiler, but anyway....

In the MQ you will end up with a castle and teleporter platform

If cannot wait. Some mods around. Some are in German, but if you do not mind a little google translating, check out "Der Wolkenturm", well worth the little bit of googling (I think so anyway).
Tab at top of launcher for mods. Check English or German mods. Have not checked TesNexus for a while.

In the game you will only be able to buy a small house in Erothin. Many modders found this to not be sufficient, and ive seen a lot of house mods around, ranging from a normal house reachable by a teleporter to huge towers and dungeons, wagons and airships that follow you around, and there is an ongoing projekt to make castle Darlan your own estate.

Actually that's already possible, without mods.
