Sub-Metering Questions Small Multi

[Justin S.]

I am currently looking at a 15 unit property with water being paid by the property owner. I have looked through the forums and have been unable to find a comprehensive discussion on water sub-metering costs and considerations. This will be the first time that I have explored sun-metering and am in desperate need of direction and stories of experience. What is the cost? Difficulties? Benefits? Read and bill yourself vs. Pay Service? Any help would be greatly appreciated! Thanks! Justin
