Final answer:
Samantha's recognized gain on the sale of her old principal residence is $111,000 after the § 121 exclusion. Her basis in the inherited home is $430,000, calculated as the fair market value at the decedent's death plus capital improvements.
Step-by-step explanation:
The recognized gain on the sale of Samantha's old principal residence and her basis in the inherited home must be calculated correctly. Samantha sold her old residence for $490,000 and had selling expenses and legal fees amounting to $34,000, which brings her amount realized down to $456,000. Her adjusted basis for the old residence was $95,000. Subtracting the adjusted basis from the amount realized gives us a realized gain of $361,000. Since the residence was her principal property and she owned and used it for at least two out of the last five years, she qualifies for the § 121 exclusion of $250,000, reducing her recognized gain to $111,000.
As for the basis in her inherited home, since she inherited the property, her basis is the fair market value at the date of the decedent's death, which is $345,000, plus the $85,000 in capital expenditures for the pool and other additions, totaling $430,000. Therefore, the correct answer is her recognized gain is $111,000 and her basis in the inherited home is $430,000, which corresponds to option c.
