Is submetering electricity/water in a duplex worth it?

[Dustin Le]

I have a vertical duplex that I'm thinking about getting submetered and I'm wondering if anyone has done this before and seen it be worth it. I'm debating because if I include the utilities in rent, then there's a good chance of overusage, but if I get the units submetered, then it'll cost about $3000 based on the estimated I received. 

Any help is much appreciated!
