Electrical update

I arranged to have an electrical contractor go to the rental property I have - the one with the electrical problem. I didn't go to the building myself to meet him, but the tenants were home, and one of them called me with an update.

The tenant described to me in general terms what the electrician had said, but said that I needed to call the office to get more information. I called the office a couple of times this week, and finally connected with the electrician today. He had made a temporary fix when he was there, but to fix it properly he wants to install another circuit, so that the basement receptacles are on a separate circuit from the main level.

He spoke quickly and had an accent, so I couldn't follow everything he said. I want to get a written report before I decide how to proceed from here.
