Cost basis of an Inherited home with a life estate

Twenty years ago my Father added my name on a Warranty Deed to convey his house that was his residents to myself and my bother as tenants in common. He also in the Deed reserved unto himself a life estate in the property for the duration of his natural life.

My Father died 5 years ago and my brothers and I sold the property in 2019
My question is for Federal Income Tax capital gains purposes when did my brother and I become the owners of the property? Was it 20 years ago when my Father put our names on the deed or when he died 5 years ago.  Also, how do I determine my cost basis in the house.
