It looks like the electrician is trying to increase the value inside his wallet on this one instead.

I carry around in my wallet my yearly goals from a professional and personal standpoint.2) For real estate I refer to Ray Dalio's book "Principles" and the notion of believe-ability.

Cabinets that are not heavily damaged can be refinished, resprayed, refaced, or just change out doors &/or hardware.3.

Without that info, it's hard to grab them by the wallet in court. 

Going to Home Depot or Lowes or hardware store to buy materials for your rental6.

Did minor cosmetic work (paint, granite on kitchen& bath, modern hardware, backsplash, landscaping) - cost: $11,350.

Work included fully renovating the kitchen, new flooring, new door hardware, new lighting, new plumbing fixtures, new mechanicals, refinished cabinets, and fresh paint.

I'd add wood and turn the cabinets into white shaker cabinets, with new hardware too.

@John S Lewis  a few ideas, some easier than others...1) search lien records through the county2) check the system itself (panels and indoor hardware) for labels placed by the installer in case of service needs, pretty common, then call them up3) see if any neighbors have similar systems and ask them who they used, then call them up4) call local installers and ask whether they worked on that property5) looked up previous owners and ask them who installed, but check with installer about status rather than rely on the foreclosed party's representation6) Don't worry about it? 

The people at the local hardware store where I usually buy my paint have recommended the Zinsser B.I.N. saying its the only primer that will block the nicotine stain, and as you stated it is very expensive.
