How do I establish a cost basis for a rental property? I claimed a refinance deduction in 2014. Do I use information from 2014 or current information?

I moved to this property in June 2016.  I converted the garage into an apartment for my personal use, repaired the upstairs living area (fully funtional two bedroom home) and continue to rent the upstairs.  We share the utility costs.  My personal portion of the total living space is 40% and the upstairs is 60%.  I plan to continue this indefinitely.  I have appropriated all the expenses into three main groups; rental maintainence/repair for upstairs, conversion of space (Residental Rental Real Estate), and shared expenses including taxes, utilities, insurance, ect.  For the last group of shared, I have taken the first six months of expense as rental, and for the second half, applied the 60/40% split and then added the rental together.  Does that make sense and is it legal?
