Some electrical needed to be replaced in the basement.  

Inspection to follow but they claim roof, electric plumbing were done 10 yrs ago.

I’m assuming minimal interior repairs (full paint, re-carpeting plus a good cleaning) at about $15k.

Level 3 -Reconstruction), 2) you are permitted (have or will get alteration permits,) 3) you are acting as the GC and have your trades (electric, mechanical, plumbing for the kitchen changes) identified.

In doing so I will need to redo the electrical to be 3 prong with a ground in order to have enough power for the new AC system.

Technically that is not correct, and could bite us in the butt, but I haven't had to fight it yet....After they vacate the property, within 45 days, you need to send them a final accounting of the damages, cleaning, etc and how their security deposit was applied..

Cheapest to move is usually electric.

We need a general contractor/Handyman with carpentry/plumbing/electrical experience to renovate a 4-plex in the first week of June in Tacoma, WA. 

Let them leave asap so you can clean up and move on.
