@Perry IvyWe have a few converted older properties (Second Empire / Victorian) in which panels were placed in kitchens, hallways and living rooms at the time the building was converted (or when the electrical was updated).One of the things we do in these cases is install a chalkboard/whiteboard/corkboard over them - a plywood box 1 - 2" deep with a  piano hinged door (which is the chalkboard/whiteboard/corkboard).You can purchase both magnetic primer and chalkboard or whiteboard paint ... a little pricy, but a little goes a long way.  

Usually has central heat the owner pays,,and sometimes same thing with electricity. 

Also He says its a legal 2 family house but it only has 1 electric meter,  and 1 boiler.

Primarily electricity and cable/internet?

Domestic hot water, and; Electricity adequate for lighting and any mechanical equipment within the home.

My son is electrician working for his dads commercial electric company.

Call utility Co and ask, although they try to get out of it by claiming confidentiality, I just ell them I'm looking at the unit to rent/but and need to know "rough numbers", they will often will say what a "budget plan # is", as in a locked in monthly electric bill of $180 for a smaller all electric home I own, but not what the current occupants' exact bill is. 

I think this guy is a little unhinged to spend that much energy telling other people on a website that someone they don't know is a fraud.

Or should I just keep everything to stay electric.

Before jumping in you really need to decide your area of investing. how much do you want to put in ... time, energy, mental fortitude (the 3 "t's"  tenants, toilets and turnover). a REIA club will help you with that. freebie seminars will help you as well.... if you learn one thing that will help you avoid mistakes, money left of table, it's worth it.
