Instead, paint the fake wood paneling white, that'll brighten up the place affordably.

Like fake paneling, it was a very trendy thing to do at one time around here.

I am also in the process of getting a house meter installed since the common areas are hooked up to their panel.

Work would be romex to 4-5 lights and outlets from a junction not the panel.

Thinking about solar panels?  

And since everyone in the house didn’t have access to the electrical panel and water shut off.

I was listening to a panel of large multifamily operators in my market and they reported service calls are down substantially.

One easy, quick check is to see how many Water meters/services there are, or how many electrical panels there are.

If you want to do everything yourself look at the list above and start putting together all the things you would need, the subs you would manage, the materials you want for finishes, if you are upgrading panels, plumbing, windows, or anything major familiarize yourself with LADBS. thats what immediately comes to mind without knowing many details of your purchase or your goals. edit: Rum comps for rehabbed duplex in the area, see what budget you may be able to refinance into in 6-12 months. if there are tri or quads in the area then consider an ADU(or two) on your lot. consider the square footage of your comps and what opportunities you have. read about ADU laws and familiarize yourself with the opportunities.
