If the tenants are already paying for the electric why do you care?

So everyone is doing it and every landlord gets bombarded every day multiple times from wholesalers bugging them about buying their house for 50% of its value.

One electrical thing to upgrade.

So are you recommending that I should let tenant bug property manager to get back to me via phone?

One of the advantages to splitting the utilities is then everyone will have a vested interest in not wasting water/electricity. 

You know that when you buy it, you're most likely not going to have any plumbing or electrical issues, and all you have to do is simple cosmetic improvements. 

I live in the Boston area and I’m looking at making an offer on a 4-unit property that has every indication it is a true 4-plex (4 main entrances, 4 identical layouts, 4 gas meters, 4 heating systems, 4 electrical meters/panels + common...but there is no record of it ever being a legal 4 plex.

Anything that would suggest electrical and plumbing are not up to code (old)? 

I'm budgeting 50k a sq  (300k) to renovate the interior: plumbing, electric, 5 kitchens, 5 baths 5 new hvac systems.  

If you are in a high tech community like Mtn View, CA the tenants do not mind Cat-6, wanting electric car chargers and will pay a premium.
