Hello, first timer here. My family has sold a property which had three heirs via three siblings one of whom is still alive. The other two heirs are children of the passed away siblings whose parents died at different times. The timeline goes as follows.
House built in 1893.
Past on to grandmother at some point.
Grandmother wills it to three children in 1984.
My mother who died in 2004 with me as only heir.
My uncle who died in 2015 with three heirs.
My aunt who is still alive today.
No heirs have lived in house since my moms death in 2004.
So, how will basis be figured for the heirs? Thank you
