I've had a few electricians diagnose the issue and have come to the resolution that I need a majority of the breakers replaced. 

Since I no longer have a day job, I just see it as a replacement as I wanted to be self-employed and I take advantage of being able to take my own deductions. 

I can't recommend the center agitator models they can damage clothes the vendor replaced that washer with the non center agitator model.

Who should be responsible for replacing, the owner or contractor?

If you're just replacing the glass, then you can go to a local glass business with the dimensions needed.

I understand that the major items like replacing floors, bath, kitchen, and HVAC will be depreciated over 27.5 years, but there are some items like scraping the ceiling, updating a drive way, and fixing a bathroom closet that I am not sure about.

Ours were off by 72% as we started to rent it, jumped to 85% once we had to replace the main water line for sewage, and finally to 106% after first tenant moved out and we decided to fix all the bad repairs by the first contractor (tile, baseboard, paint and etc) and damage from the tenant.Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

I Have a bungalow with a legal basement suite in Avenmore and I need to replace my manager.
