Could be a house that has old none grounded cloth wire .I go a rip all that Sh... out pull new wire ,hire a pro pull a permit  to set up the panel .This can cost a lot or not so bad .Now you know what the comment about put it back like  you never seen was all about .

I think my panel is already over buffed.

Arlington Ave in IrvingtonPurchase Price $749774 Bed 2 Bath 2370sq feet SFHHas New HVAC, New Water Heater, Updated Electrical Panel (150A), roof is 4-5 years old with no leaks. 

I found an electrical panel (updated breaker box) with 200 amp service.

Two of my three 1950's buildings have had to have complete electrical upgrades (service, meter socket, panels, circuits to kitchens).

I've had people ask for ceiling fans in the family room and solar panels, etc. 

I have a friend who's in sales for solar panels.

there were some required replacement items such as some outlets needed to be replaced and I upgraded the electrical panel from a fuse type to breakers.  

We're glad to hear you bounce some specific ideas around here and offer some thoughts.To answer some of your questions:My skillset includes minor welding, minor housework (I lived in fostercare and the father owned property in which I helped lay tile, wood paneling, drywall etc.).

The city of Los Angeles is not currently requiring solar for new ADUs.
