How to convert single HVAC in a multi family to individual units

[Ricardo Sancez]

Hello BP Members,

I am evaluating a deal for 10 unit building. The building has single water heater and single heating units with outlets to all the 10 units. Currently, the owner pays for hot water and heating. I would like to convert this individual units so that tenants pay for hot water and heat. Owner would still pay for water. 

Any ideas on cost and how to go about this ?

Thank you
