I operate them as a sole proprietor by the way.What do you think about the idea of looking into the policy and cutting out some coverages to downsize the premium?

Here's a link for the source of the data. 

We flip in WA state where the market is hot and I have been challenging myself on what is good and what is over the top.if you spend time searching Amazon, clearance sections, Ikea, &  build relationships with vendors (my countertop Co) you can source current on trend finishes and not spend a ton. 

Or is it a MLM approach, providing a main source of income for the gurus/coaches to go fund their own deals?   

As long as you promote your properties for rent on the main channels, such as Zillow(One of the best, as it crawls quite a few sources), AZ Republic/AZ Central (Heavily read by many PHX residents), East Valley Tribune, Craigslist (inferior, due to scamming and lack of reach, but still works and free), etc, you will generate a lot of interest.

I've looked at rentometer, craigslist, hotpad, zumper, and other sources out there.

I use propstream for one source of leads and to do smaller post card mailings.  

You should also ask where they source their data from.

I wrote a detailed post on Reddit about how I passed the CA brokers exam without paying for any course (only used free study sources in other words).
