Estimating Water Sewer Garbage

[John Cook]

Happy holidays everyone! I'm curious to know if anyone has a method of estimating water/sewer/garbage for 2 bed/1 bath apartments. It appears that Sacramento is a "landlord pays water/sewer/garbage" city so if any landlords can share their tips on estimating this expense, especially when determining cash flow for potential investment properties, it would be most appreciated. Does anyone actually look up historical expenses per unit? is this possible?
