Turned out not to be too hard, it is a lot of work but looks so good when done. 

The buyer would need to show solid financials also of course (good credit, experience operating rentals, proof of funds for down payment and adequate reserves to cover any unexpected cap ex).

The only good use I can see of the fees are based on rent charged would be for a tenant to purchase it and charge themselves $0 or near $0 rent to avoid the rent based charges. 

Buy and hold it is good.  

I would find a good real estate agent focused on investment properties and look at up and coming areas.

I used to think all realtors were more or less the same as well :)Of course there's good and bad and shades in between.  

Quote from @Austin Wolff: As someone who lived in Los Angeles and also needed to invest out of state, I've dedicated my career to market analysis and selection, and I personally think you've chosen pretty good markets.

Fears/risks: the underwriting projection seems too good which likely means very aggressive.  

I am in the process of analyzing my next purchase and I was curious what resources people use to gauge how much they could rent a property for.  Is there a place where I can type in the address of the properties I am ...

Partnering with a wholesaler sounds fine, but check the real estate licensing laws in your state before bringing a buyer for a commission.You might consider getting your real estate agent's license and legitimately earn what your skills, drive, and experience truly command. exactly wholesaling or bird dogging is not a life time or long time occupation  RE sales can be lifetime and if your any good at it at about year 10 you should be getting all your sales from referrals and such.
