Separate utilities?

[Brian Spink]

I'm looking at a house that has a one bedroom apartment attached to the back. Utilities are not separated between the two. The cost to have separate meters, etc. is not something I want to pay for at this time (over $3000 just for water hookup).  My next option is to pay for utilities myself and pass it on to tenants (more work and likely issues on my end) but how does one split the bill?  The house is a 3-1. The apartment is a 1-1. Ideas?  Solutions?  Or even better.....experiences. Thank you.
