My wife's mother died in 2020. My wife put the house up for sale within a few months and it sold in 2020. The realtor (who she assumes knows the value of property in the area) listed the house at 89,900. It quickly sold for 95,900 (a bidding war). Is the basis 89,900 or 95,900? After closing costs and fees, the house sold for 85,900. Can she claim a capital loss? How much?
