Renting Basement Apartment??

[Wells Lange]

My wife and I are considering buying a house that has an 840sqft 1 bed 1 bath apartment in the basement. Does anyone have experience with doing this? How would the utilities work? Primarily electricity and cable/internet? I could see having all those utilities included be an issue because then they wouldn't care about running the heat/AC and I can't even imagine letting them hookup to our cable tv? But I don't think the city would meter utilities separately because it's zoned for single family. And what if we wanted an alarm system? Would we include the basement?? Any input would be much appreciated!!
