Disclaimer: I'm not a licensed electrician but have installed a few hundred switches, receptacles, and light fixtures.  

I'd appreciate it if anyone have has experience with Philadelphia rental properties and can shed some light onto property tax problem I am facing.

There is a light at the end of this tunnel, but I can't put a date on it yet.

Also, if you can't make up your mind on light fixtures or paint, or you order plumbing fixtures and are missing parts, then it's not your contractor's fault so you need to account for days in a fair way.  

Also most garages do not have standard outlets and lighting since it is not considered living space.

(in light of the above) I am ready to listen and learn! 

thanks Joshus Light!
