The Seller is not required to anything.
If you put something in writing in the initial Offer, if would be part of the deal.
But if you came back after inspections and gave them a list, they can thumb their noses at you and let you walk. If they were willing to lose the deal over $200 worth of repairs.
If I was your Agent, I would suggest that you get used to being a homeowner and take responsibilty for your own repairs.
It sounds like the Seller is being more than accomodating.
good luck and may God bless
