客人在（客房）地毯上烧的烟洞 Putting cigarette burns in the (guest room) carpet 以下是一业主向租客索赔案例： A tenant puts several cigarette burns in a living room carpet. The landlord says it will cost $1,000.00 to replace the carpet. The landlord provides evidence to show the carpet is 10 years old and was in very good condition when the tenant moved in. The landlord also provides evidence to show that the useful life of the particular carpet is 14 years. The tenant agrees with the landlord’s information. The Branch awards the landlord $285.72 for the carpet. $1,000.00 (replacement cost) ¸ 14 (years of useful life) = $71.43 (annual value). $71.43 x 4 (remaining years of useful life) = $285.72 (loss of value).
