Answer:
$207,700
Step-by-step explanation:
Blake's basis in his home in 2017 = purchase price + legal and administrative fees = $200,000 + ($700 + $2,000) = $202,700
Since the deck that Blake added to his home is considered an improvement that is permanent and increases the home's value, it will also increase the home's basis = $202,700 + $5,000 = $207,700
