Averaging all bills for complex??!

[Dylan Bard]

Hello!

I am acquiring a 7plex in Aug. I was thinking of paying all the bills. There are 4 electrical boxes with the 7 units (conversion house), I'm not exactly sure which box is for which units. I wanted to pay for everything but mitigate people using too much of the utilities. Can I average out the electrical bill for all 7 and make them pay 1/7 of the bill or... let's say the bill is $700 usually, can I put in the contract that anything over $700 is evenly distributed throughout each unit? If so, how would I put that in the contract?
