none of the above. Land is rarely depreciable. the only situation I've ever come across where it was was when it was used as a waste dump by a private company. after so much no more use.
as for splitting the cost of real property between land and buildings, it's supposed to be based on their relative values. however, many tax bills do not reflect their true value. ask a realtor in your area.
Thanks for the response. Yes, I am aware of that. I'm asking in the context of subtracting the value of the land from the purchase price of the property.
