This of course assumes that this property was not acquired in a 1031 exchange.However, any costs incurred to acquire your mortgage (if you have one, which it sounds like you do since you got an appraisal) should be amortized over the term of your mortgage.Also, there are some costs on your closing statement that you may be able to expense immediately.Also, it's possible that you incurred some additional costs that increase your basis in the property post-acquisition or possibly even pre-acquisition.You may also have start-up costs that you may deduct up to $5,000 (assuming you don't have in excess of $50,000 of these costs), the excess being amortized over 180 months.Check with your tax professional.
