Water prices in how to bake them into Rents

[Maria Bocanegra]

I am in the process of purchasing a multiunit where I will owner occupied. I am trying to figure out how to properly estimate water, sewage, trash and bake them into Rents.  The building is currently under contract and will eventually be rehabbed. I have some time to think this through so I thought I would reach out to all of you to see how you address this. Thank you so much!
