Final answer:
Faith's adjusted basis for her one-tenth undivided interest in the inherited land is $1,100,000, as the executor elected the alternate valuation date, and the land's value was $11,000,000 six months after her father's death.
Step-by-step explanation:
The adjusted basis for Faith's one-tenth undivided interest in the land, given that the executor elects the alternate valuation date, is $1,100,000.
When an individual inherits property, their tax basis in the property is the fair market value on the date of the previous owner's death (known as a step-up in basis), unless the estate chooses the alternate valuation date, which can be six months after the date of death. Given that the estate has elected the alternate valuation date and the value of the land is $11,000,000 six months after the death, we would use this lower valuation. As there are ten equal inheritors, each sibling, including Faith, would inherit a one-tenth interest. Therefore, Faith's adjusted basis in the land would be one-tenth of $11,000,000, which is $1,100,000.
