I purchased a house in 2001. It was a rental through 2006. Since then I have been working on the house and trying to sell it. It finally sold in June of this year (2017). I have not taken any deductions since it was rented in 2006. Can I deduct the expenses (taxes,insurance, etc) since 2006? If so is there a specific place in the IRS code that addresses this?

Thanks,
Greg
