I’m a believer in renting things to pay for them. A few years ago, my wife wanted a 30 foot travel trailer so we could “experience camping.” I helped her setup a corporation (she’s a school teacher with zero business experience or interest), we bought one, then rented it out. Of course, we insured it.
In the end, it did work out, kinda, sorta, albeit only because we had flexibility and as a school teacher, she had the entire summer off to enable her to meet and show at the pickup, and then inspect at the drop off. Since I often work from home, I made a point to stay home on those days when I could.
A small sample size, however, about 80% of the time there was “something” about “something” that either needed to be fixed, or worn out. Only once did it rise to the level of taking the security deposit from damage, but we did charge extra when it wasn’t returned on time with one rental, which cost me a day of work because they returned it late when I already had other plans. This is something that could effect you too. What if someone is renting it and due to delays like weather they keep it for a few extra days. You can charge extra premium rent, albeit you may not be able to recover what you have to pay another to rent a similar unit.
Then there’s the whole insurance aspect. Your current coverage most likely has an application that includes language of “do you rent equipment” that you likely signed no to.There’s also likely exclusion language for renting as well. The key is if you can have one policy for both activities to create efficiency. That may come from a waiver because you’re not renting it often, albeit that may be considered a greater liability because of lack of industry (rental business) expertise. Bottom line, absent an ability to avoid a second policy, the numbers may not be so attractive in renting.
After three summers of renting a travel trailer, my wife and I learned that the numbers worked only because we owned it anyway for our own use (kinda what you have here), I became very good at maintenance and repair of travel trailers, and we never plan on doing it again. On a positive note, we were able to use the travel trailer for about 10 times (about three trips a summer) and our final cost was about break even.
Best of luck with whatever you decide
