Jersey City power is not cheap. you will lose money mining unless you have free power.
Once the landlord sees 1200 watts or 1.2kwatts x 24 x 30 = 864 kwatts he will want to charge more money.
Some advice if the power is 'free' do not be a hog about it get a better miner and use less power.
The s-5 is able to clock to 1000gh and use 500 watts alter the fans it is pretty quiet.
Not only want to charge more. But in this case it sounds like a good way to get you landlord mad if hes the apartment under you and it lets a lot of sound through.
I would never make it this situation.
