Thank you. I will have to test if those methods count towards fulfilling such quests. I should note that I am not selling them for the money. By the time you have trained a slave to be loyal enough to sell like this they could make you a bunch of money from a job.
The reason I am selling them is for the mansion upgrade points. It doesn't matter how much money I have, I can't upgrade the mansion without upgrade points. which you only get from completing quests or selling a slave of over 90 obedience. I prefer the repeatable slave request mini quests since they give out more mansion points per slave
