Utilities are OFTEN overlooked so reach out to power, telecom, gas (or go all electric), water, and sewer to make sure you understand what it would take to get separately metered services from the primary house.

What is the best overall water metering company you have found when it comes to ease of installation, reliability, and the cost of the equipment and monitoring?

I'd be surprised if the complex doesn't have individually metered units so you may be able to eliminate the utility expenses unless those are for common areas like walk ways, parking lot or laundry.

I do own two triplexes in Scranton, and I will say the one issue is that you are going to be taking care of the utilities normally if they are not on separate meters, which could take a good amount of money away from your overall cash flow. 

Water is shut off and they are removing the electrical meter.

The garage does have electric ran with a small meter base.

Licensed with permits ~$4,000.Full replacement of all water supply lines and shutoffs from the interior water meter with PEX and an open basement.  1 kitchen 1 bath 1 laundry. 

Electric is metered separately from the utility. 

Another avenue would be to call your utility companies and ask about installing additional meters.

I also have five gas/electric meters.
