Answer:
$55,000
Step-by-step explanation:
Since Harvey and Margaret are married, their § 121 exclusion = $500,000 since they meet all the ownership requirements. The gain resulting from the sale of their Charleston home was fully excluded ($292,000).
Since the sale of the second home is within the two year window period, then the recognized gain will be:
realized gain ($180,000) - § 121 exclusion ($500,000 x 6/24 months = $125,000) = $55,000
