It is possible that you are simply depreciating the house that you are renting. In this case, the depreciation period would normally be 27.5 years. So, if you knew when you first started renting the house, you could do a simply calculation to determine the depreciation taken in prior years.

Please remember that you can only depreciate the building, not the land it sits on. So, you would need to know the cost you assigned to the house to determine the correct depreciation.

Also, the cost of the house would only be listed on the first form 4562 you listed it on (the tax return for the first year you rented it), after that just the depreciation amount would show on form 4562.
