Switching from Owner-Paid Utilities to Tenant Paid (Duplex)

[Tyreek King-El]

For a duplex I'll be closing on soon, the utilities were owner paid. Is it fair to say that that can go out the window as soon as the current tenants are out (which they will be before close)? And if so, for anyone who has used the RUBS system, what is your rebuttal for the instance that is a tenant not using the utilities that my RUBS system calculates them for using? I understand RUBS is a mathematical way to assume what each tenant uses, but truly how accurate is it? And lastly, anybody have experience splitting meters, how hectic is that process?
