Time to do a little math.

All this assumes that you can install hardware today.

Network Thash/s Today   6,357,467
Blocks per Hour Today   6.94
Bitcoins per Block   12.5
Bitcoin Value Estimate   2824
Calculated Information as of TODAY   
rewards / day   166.56
BTC Reward/Ghash/S/Day   3.27489E-07

If you can install 110 TH/s, you'll earn:

BTC Reward/Day   0.035015116
Estimated Earning/Day USD   98.88268718

That's 8 Antminers, which would consume 12,000 watts.  You'll burn 12KWh per hour.  288 per day.  8640 KWh per month.

If you have to wait until September, you'll need somewhere between 10 and 14 of them. 

Note that none of this math accounts for cooling.  12,000 watts makes a lot of heat.

Good luck with your empty house.
