Investors & landlords

"So cost incurred between the closing date and the in service date "preparing the property for rent" are not deductible. Period. Just don't confuse those non-deductible "getting it ready to rent" costs, with property improvments. Two completely separate and unrelated things."

 

If they are not deductible, aren't they depreciated?   If they are depreciated, are they not considered an "improvement"?  If they are neither, what are they and where are they tracked?
