Are you asking if the $ 30- 50K can be expensed?

Terry's observation is correct; IF the property is still available for rent during the renovations the costs are 'deductible'..... but that doesn't change whether the costs have to be capitalized & deducted thru depreciation, or expensed as repairs/maintenance.  It depends on the nature of the cost(s), and perhaps the amount.  Research TPRs -Tangible Property Rules (or is is Regulations?)
