does that even make it profitable?

I am shopping around for space to build my next rigs into and expand myself. At my current operating cost and earnings mining on zpool mainly, im averaging right around 1 to 2.3 ratio. So for every $1 ive put into the setup, it will net me $2.3/yr tell all the equipment is payed off over the course of a year, then its just overhead on the equipment.....

I have been thinking of just buying a small 2 bedroom fixer upper house with garage space and turn the garage into a cooling chamber. I have my main PC at home that is watercooled and just a week ago i took my hottest rig, which is 4 x 1080ti MSI Armors (terrible cooling cards) and installed Kraken G12's on them with universal GPU blocks from ekwb to keep the cost right around $60/card to convert. i have the rig sitting in the laundry room as a test location (the laundry room is the room you have to pass through between the kitchen and the garage. I ran pex line temp through the drywall into the garage and i have the radiator sitting in the garage cooling the rigs, so far the concept is working out... my card temps are far lower than any air card i have running, but the temps are not as nice as the watercooled gaming pc, because the garage has no windows and only ventilates through a leaky garage door, so the room over time gets to a set temps and just stays at that temp. If i was to ventilate the garage more i am almost certain i could get the cards down into the low 50's on temps.

The idea would allow me to just leave the computer/rigs inside the house to be cooled by the a/c to some degree leaving the a/c set in the 80's, but majority of the heat would be pulled out of the house via the waterlines and dumped into the garage to be vented to atmosphere.....If the test rig continues to be reliable, i plan to upscale this to multiple rigs, because you gain a small % of additional earnings from the cooler temps on the gpu's also.. to offset the cost of the conversion. The reason i dont want to buy already converted gpu's, is because if i do want to dump them i can just put the air fans back on and sell them, otherwise i would be stuck with 50 watercooled gpu's for a niche market to buy used... plus using the kraken kit along with a universal water block allows it to be transferred to another card in the future when i upgrade.

Plus if i buy a cheaper 2 bedroom fixer upper in my area, the mortgage and insurance would run me around $300/month, so the rigs would literally act as house renters and pay the house for me over time.
