Steve purchased his home for $500,000. As a sole proprietor, he operates a certified public accounting practice in his home. For this business, he uses one room exclusively and regularly as a home office. In year 1, $3,042 of depreciation expense on the home office was deducted on his income tax return. In year 2, Steve sustained losses in his business; therefore, no depreciation was taken on the home office. Had he been allowed to deduct depreciation expense, his depreciation expense would have been $3,175. What is the adjusted basis in the home?
