After all of their children have been married, Milsa rents their top floor to anyone who does not mind being locked in at night.
(Reference: Winter's Heart, Chapter 33)
"Milsa had stairs put in right up to the third floor, so it's private, but she wouldn't pay for having a new door cut as well, so the stairs come out in the shop, and she's not trusting enough to leave that unlocked at night." (A man selling meat pies to Rand; Winter's Heart, Chapter 33)
