And the reason you would have to charge $50 per hour is to cover the liability insurance.
WRONG…Never even considered it. Sorry…but spend some time and do the Math…
A simple 10 bay garage in the Boston (outside of the 495 belt) area can easily run you 10-20k PER month…If in Cambridge…try $40k/mo.
Those lifts aren’t cheap…Not to mention heating/water/damage…and there are LOTS of things I’m NOT including…Insurance is NOT of of them.
I do know a guy in NH that does it. He’s a mechanic with a 5 bay garage…He’ll rent out 1-2 of the bays from time to time. But 90% of his income come from his business.
