Here is a summary of the deal:Purchase Price: $500kDown Payment (using FHA): 3.5% - $17,500Property Taxes: $4,500Insurance: $900Total monthly payment (PITI + PMI) = $3,325/monthThe units are currently being rented out at $1,000/month, so essentially if I live in one of the units my payment each month would be ~$325, not including utilities of course.

The only reference I have is for my duplex and triplex properties in CO; sewage, water, garbage and share common area fees paid by me; tenant pays gas and electric.

The most common method is driving for dollars.

Obviously, we are looking at raising rents but we are also looking at "Rubs" Ratio Utility Billing system as an alternativ e.

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)

how much should i put in collateral for the best utilization, how can i calculate utilization ?

A very common thing I see is people have a "mortgage buddy" who is great at residential stuff but totally novice with non owner occupied investment property loans. 

I feel like the forums in general are not being utilized properly.

The total building may be 3,000 square feet, but the individual units will of course be smaller (plus there are common spaces).I also wouldn’t totally rely on the city assessor’s records for square footage. 

I utilize Cornell Law School's public database.https://www.law.cornell.edu/uscode/text/26/4975The language is as follows, with the specific word "between" used: (my emphasis below).
