[quote user=invst4profit]your best option may be to have the main house tenant put the utilities in there name and the cellar dweller would reimburse them 40%. Or you put the utilities in your name and the lease is plus utilities divided again 60/40.
This second option may be best as it eliminates disagreements between tenants but at the same time guarantees (sort of) that tenants pay 100% of utilities.
This makes total sense, as water+ewer+garbage+gas + electricity will run you between $2500 and $3500 a year, with spikes well over $400/month in the winter, depending on location, insulation and tenant's idea what "comfortably warm" means.
Plus, unlike apartment buildings where utilities are usually included, it is common in houses that they are on top.
Have a lease that uses one of Brett's suggested options, and if you pay for it, add $300/month ($180 up and $120 down) as an estimate, payable every month to you as part of rent, adjusted annually (say every summer once all the winter bills are paid).
There is also water and garbage, which in many communities (but not all) is added to property taxes, and in some others billed separately, via separate bills or in conjunction with gas or electricity bills.
Find out what the process is in that particular town.
Also, please be aware that in some (but not all) communities the town has the right to bill owner if the tenant defaults on utilities !
