I will shortly be moving from my current residence to a home I recently inherited from my mother. I plan on using my current residence as rental property. It will be totally paid for in 6 years. How do I treat the mortgage interest on this property on my Federal income taxes? Obviously I have alwasys included it in my itemized deductions, but now that it will not be my primary residence, but rather a revenue generated residence, how do I claim the interest on the mortgage? I live in Oklahoma.
