The two commercial units share one meter, and the three residential apartments share another meter, and electric bills are astronomical.

The meter is connected to the internet and I can monitor water usage by the hour, day, week, month, and year.

You'd have to look at proximity to panels, metering, etc there too as you'd have some load (copper wires) to likely pull.It typically costs a lot more to heat using electricity vs NG, so I guess you'd be passing that along to the tenants?

Great info/points.I would own the lines from the water meter to the MH, Electric from the meter down to the MH, and the sewer lines that are on the property.

If you're a tenant reading this, when you move in, check the little wheel on the water meter and make so no water is being used when the house is vacant.

But all my units have separate meters for both electricity and water. 

If it is built after a certain year they require that you put in individual meters instead.

Is there a source for the following data;  I am looking for the "norm" for the expense ratio (based on either GPR or Gross Income) for individually metered garden style apartments in the south east and the mid Atlantic (Region IV) : Marketing Insurance Janitorial Service Lawn/Snow Licenses Miscellaneous Professional Fees Accounting Legal Property Management Fees Repairs and Maintenance Resident Superintendent Salaries and Wages Supplies Taxes Real Estate Personal Property Payroll Other Trash Removal Utilities Electricity Fuel Oil Gas Sewer and Water Telephone Other (whatever I missed)

Or if the unit (multi family) has one meter for the whole unit vs multiple units.

I'm also looking at installing a smart water meter system to bill back water to tenants as well.
