Sales Expenses

Received Sellers Statement and I understand as the Seller, Mortgage charges/fees and Selling/Listing agent commissions are considered selling expenses and can be added to seller's basis to reduce cap gain. On the Seller's statement there is also listed a Seller Credit under Primary charges/credits and a temporary buydown paid by Seller under Misc Charges. Are either of these also considered selling expenses to increase the seller's basis and reduce the cap gain?
