Firm L owns a commercial building that is divided into 23 offices. Several years ago, it leased an office to Company K. As part of the lease agreement, Firm L spent $29,000 to construct new interior walls to conform the office to Company K's specifications. It capitalized this expenditure to an asset account and has deducted $6,200 depreciation with respect to the asset. Early this year, Company K broke its lease and vacated the office. Firm L has found a prospective tenant that wants Firm L to demolish the interior walls before it will sign a lease. What are the tax consequences to Firm L if it agrees to the demolition?
