He didn't take anything for the last 10 years since he didn't file tax returns for the last 10 years.
We also don't know what type of "property" this happens to be since @user17684044706 did not specify that in the original post. It could be anything from residential real estate to nonresidential real estate to vacant land.
We also don't know if there are any passive loss carryforwards and, if so, the total amount. That could greatly affect the amount of gain on this transaction.
