Basis after rental property improvements


For purposes of figuring tax basis for my rental property, the original building date of service was in 2004, original cost of $77,648, and accumulated depreciation of $21,821 thus far, leaving a basis of $55,827 to plug into the current year of my depreciation schedule (which I would enter in the "Basis" portion of Real Estate, General tab. However, in Sept. 2014 I took out a loan for building improvements in the amount of $180,815 that will begin their own, new 39-year depreciation schedule starting in Sept. of 2014.

In lieu of this, how do I come up with a number to enter in the "Basis" input for this Real estate holding?
