Final answer:
The correct answer is option B. $35,000 , calculated by finding the decrease in FMV due to the fire and accounting for insurance reimbursement and basis in the property.
Step-by-step explanation:
To calculate the casualty loss, we start by determining the property's fair market value (FMV) before and after the casualty, which was $120,000 and $15,000, respectively. The difference between these two amounts is $105,000, representing the decrease in FMV due to the fire. However, to find the actual loss, we also have to account for any insurance reimbursement. Since Jen received $85,000 from the insurance company, we subtract this amount from the decrease in FMV, resulting in a loss of $20,000.
However, this does not consider her basis in the property, which is the original cost plus improvements. Jen paid $90,000 for the house and made $10,000 in improvements, so her total basis is $100,000. Since the loss ($20,000) is less than the basis ($100,000), the entire decrease in FMV due to the fire is the casualty loss. Therefore, Jen's casualty loss is the decrease in FMV of the house, which is $35,000 (the $105,000 decrease minus the $70,000 remaining value of the house and land before the improvements).
