There was a topic in the forums where folk was asking or suggesting new mods. There you got the question, if there is a possibility to own the houses that remained empty after someone had died in a quest, for example Agarmir in the Unfriendly competition Quest. 
You'll get the key to the house, but it is nethertheless owned by Agarmir, you will not be able to sleep in the bed, to wait in the rooms, you are trespassing in a uninhabited house.

To change that, I thought out this mod. Now there are nine houses that can be available to buy after you end the connected quest. You'll get a flyer with description (there you'll be informed about secure storage chests, so unless you have that stored in your memory, don't cast them...). 
If you don't get a flyer, head where the things happen, in the Market District ;) 

The whole ting should run ok but if you come over a bug, please let me know.

Enjoy!
