Another factor to consider is infrastructural investments which might need to be made. If you're only planning on running 1 miner and you have a free circuit then great! But if you try to add 2nd miner it's not going to happen @2000W so I hope you have a 2nd circuit free or you need to factor getting an electrician to install a new one for you.
Really, if you are currently considering buying any of the currently available 8+TH miners at home, think again. Especially @110V . They are too loud, too hot, too power-hungry to do so. They need to live in a hosting facility with the lowest power costs you can get.
