User error is likely not the landlords fault, or the manufacturer's fault."

Of course, Auntie Mabel, there is absolutely no chance that this guy might decide to manufacture meth as his next venture, even though it's extremely lucrative and all he needs is a kitchen. 

In a KAIZEN for a manufacturing process for example, (sorry for nerding out here), a process/work flow is studied to determine areas of waste and in turn develop a procedure and/or work instruction for the job function in an effort to shorten lead times. 

(like a john picking up a prostie) However, if it  was anything to do with manufacture, trafficking or dealing I would say no ****ing way even if his parole officer said he was an angel. 

Equipment should also be warranted from the manufacturer and you should receive a minimum performance contract included.MYTH: You will have the option to upgrade down the road.FACT: Leasing companies must own the system for at least 5 years or suffer federal tax credit recapture.

If you care, you should check zoning to make sure you're zoned for whatever you're going to allow to happen if you're renting to guys that are going to work or manufacture or run a business of any kind.  

There is positive job growth from the tech industry, manufacturing jobs from Tesla, geographically restricted building, no income tax, low property taxes, close to CA, mild weather, and landlord friendly. 

I wouldn't worry about it, unless it seemed like something else weird was going on - like you though it was just a place to manufacture drugs or something.

After all, there is only one appliance from that manufacturer that will have that serial number, and you are documenting that it is yours.

Honda's have some of the most records out there of any other manufacturer.
