selling coop father passed away

[Lily Ochoa]

Good Morning any advice on how to go about selling coop 2021 I was able to transfer coop to my name : dad (co owner) passed away 2023 and uncle owner of unit (cancer) legal transfer shares to me. Now I need to sell coop not sure is it considered an inheritance I do not live there my nieces are residing they would like to move out and sell coop to get their share have to them and my sister as well. How can safely do this to avoid capital gains on unit. At least be able to have fees taken once unit is sold since party asking to sell will not pay me anything when I do my taxes. Presently a coop unit similar to unit I have sold for 480k no pending mort on unit.
