Dave Ramsey's training is structured towards personal finances.

I train my team to not waste their time snaking if they can’t fix it in 10 minutes and just replace it since toilet is under $300 (I use $120 Costco ones) but yeah these things are difficult to know for regular hosts.Besides that, it is unfortunate but I kinda see why Airbnb made that decision.

Look for one that includes a training video to ensure you understand how to best use it.

I saw last week that you can get trained on the JOB to repair Elevators and start at $150,000 a year.

My two bedroom is currently being rented out for 1900 and the training is coming in the spring.  

Plus, they are watching their co-workers one at a time move this way and they want to "jump on the train" and join them by owning property here. 

I have a free training on YT on how to do this.

In this instance the judgments (20+/-) are already issued, now its a matter of collecting while the individual continues with their training programs and buying loans.

Simple: It’s the real estate version of a training wheels bike.
