A local hub to go get tools is the only way this works, in my opinion. Your current offering is obviously compelling from the renter’s perspective. I am renovating a cottage and would love to go pick up a chainsaw, brush cutter, etc for half the price of Home Depot (they have everything and great service).
But I just don’t see it from the tool owner’s perspective. My suburban aunt has two chainsaws sitting in the garage that she doesn’t use anymore. An extra $150 a month isn’t enough to deal with the hassle of coordinating meetings, dealing with damage, etc. And she definitely wouldn’t be giving a free tank of gas, PPE, etc like Home Depot does. She would gladly drop it off at a local spot, make passive income, maybe go grab it herself once a year when she needs it.
Ps - great website design. Looks beautiful on mobile and works really well. What are you using on the frontend?
