Provide and charge wifi?

[Ryan Kenneth]

I'm considering providing wifi for the tenants in my 12 unit building in NB. The plan would be to charge a fee that would be cheaper than what the tenant would otherwise pay but with enough margin to make to worth it for me.

I've yet to find anyone whos actually done it successfully, nor did I have much luck finding info online so I wondered if anyone here has. 

Curious to hear your guys experience or thoughts.
