Okay so I've got my house made and I want to make it buyable. I've got an NPC ready to go, all I need to know is how to make the quest and add the dialogue to the character to make it work in game. The house starts off disabled so one of the conditions needs to be that it activates an X marker that enables the house, much like when purchasing upgrades from your home in vanilla Skyrim. Can someone help me figure this out?
