While you clearly have an economic loss, tax rules prevent you from deducting the decline in value from your $120,000 purchase price to the value at the time you converted the condo to rental property. What’s more, depending on the amount of depreciation claimed on the condo from the time of conversion, you may actually have a tax gain (even though you have a financial loss). Talk with a tax pro to run the numbers in your situation.
Costs that are not currently deductible and that are added to the basis of property. A capital expense generally increases the value of property. When added to depreciable property, the cost is deductible over the life of the asset.
