Great information. Thanks for sending a link to the deed. Looking at the deed, your grandmother gave your mother a "remainder interest" in the property. Your grandmother retained a life estate. This means that your grandmother's life estate interested terminated upon her death. The remainder interest does not terminate at death but a right to own the property after the death of the life estate owner. The remainder interest is a "forever" interest that passes to the heirs of the remainder interest owner.
The property then goes automatically to the remainder interest owner (your mother or her legal heirs) upon the death of your grandmother. It does not pass through your grandmother's estate but passes through your mother's estate to her heirs, upon the death of your grandmother.
With that said, once the property is in your mother's estate it is a bit complex. The property DOES NOT go fully to your step-father. Your step-father receives a 1/3 life estate in the property. You and any siblings you have would be entitled to 2/3 and the full remainder interest which means the full property reverts to you upon his death.
By the way, sorry to hear about your history with your step father. Sounds like you have found a good career. If you are in the military, thank you for serving our country!
