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.
A revenue ruling is the Commissioner’s “official interpretation of the interpretation of the law” and generally is binding on revenue agents and other IRS officials. Taxpayers generally may rely on published revenue rulings in determining the tax treatment of their own transactions that arise out of similar facts and circumstances.
