So, even if you don’t want a degree, I would say participate in some class or learning program that requires you to do more than just receive information from an instructor.

I think in-person training can be more valuable as you get to participate in conversations with the class and hear anecdotal stories from the instructor, which all help cement important points.

I have found that this and other posts like it apparently revolve around what CNN / MSNBC keep instructing people to feel, think, believe.

To search, I've a link off of my profile to a short instructional PDF I wrote up (I got tired of explaining it) about how to search the commercial site www.LoopNet.com (which is the Zillow for commercial properties; 4units are commonlyconsidered commercial). 

We provide instructions regarding move-ins and move-outs to mitigate damage to our property.

We put a binder together with owners manuals and instructed them to use it before calling us so we didn't get calls the oven doesn't work.

I put this in my vehicle guest instructions.

I concur that coming to the live class is a much better option since it allows for a lot more information to be presented by our national team of instructors and there are 3 days for you to get all of your questions answered there as well.  

For the wood floors I do get an instruction sheet from my hardwood floor guy and give it to each tenant.

@Russell Brazil  on our latest subdivision that's exactly how it works my wife or one of her fellow agents holds them open sat sunday.. buyers agents instruct their clients to go look.. if they like it they follow up.. but to be honest my wife usually has to hand hold quite a few of the newer agents.. and helps put them together we are always pleased when we get to work with an experienced agent.. but hey we own the houses so what ever it takes  LOL..
