so, every single rental yard here (locals to nationals) has the same insurance policy. It's X% on top of the total (like 15% or more) and all it covers is if the equipment fails while you are using it (ex. the engine blows up). It's NOT like a rental car coverage which is what everyone thinks it is. If you damage it thru user error (ex. flip it into a ditch). YOU OWE!!!
Just FYI, nobody seems to realize that. Getting paid when some local residential guy flips a $50,000 trackhoe is going to be tough. A good lawyer to write up ironclad contracts is going to be key.
rental yards are a tough business, between maintenance, insurance and running around to get the stuff, you've got big costs. You've got big compliance costs from EPA, DOT and local zoning/business/etc.
You've got sales tax issues (and every state seems to have high rental equipment taxes), taxes for the equipment itself, taxes on the business land and building. Remember that commercial buildings are not only taxed at a much higher rate than residential, but utilities are MUCH higher for commercials also. (and you'll certainly use a lot of heating/cooling in a big bay).
Most national chains (RSC, volvo rents, etc) make less than 10% margins, most are less than 5%. And they get way better advertising and better deals (volume) when buying than Joe Blow the single location can get.
Rental yards are very dependent on new construction, which of course is in the toilet and will be for some years. Residentials aren't your main customers, contractors are.
the biggest problem with a rental yard is dead costs. You have to have the equipment, but it isn't going to be rented all the time. Finding out what that usage rate is is going to be key for structuring your pricing. (is it 20% or 50% or 70%?). And then seeing if you can make money at what the going rate is. Rates here haven't really moved in 29 years despite the cost of equipment going up and up.
HTH
good luck.
there has to be a rental yard business magazine/organization. It would be well worth it to find it and subscribe. Tons of issues that only insiders would know.
