This is a great place to throw out ideas and get answers and differing opinions on problems you may encounter.  

Providing a solid and complete package to a lender upfront goes a long way.  

Ive heard so many times about this "presentation packet" or package so that the "lender won't have a hard time" in the podcasts, yet it is not being discussed here or no one have shown example.

This is what I am encountering, in the current Mortgage Industry.

As @Jay Raught said the notes that you will encounter will be either from local banks and I would add hedge funds. 

One solution would be to make a commercial product; assuming you purchased more than one, by marketing them as package deal many more investors will be interested given the higher dollar amount and cash flow.

I literally had an attorney from Butler and College refuse to do a loan documents package for me because ... it was an REO.

They should also contain an Analysis by Replacement and an analysis based on Income.... which is sort of like the Analysis I did with the Cap Rate and Purchase Price.Generally, because most Appraisers I have encountered really don't understand it themselves, they generally conform the Replacement and Income analysis to the Sales Comps.

I just got the $99/mo unlimited scanning package (3 recipients) at Earth Class Mail.  

If you can pay the $40,000 for the premium package without blinking, then maybe these so called coaches can put you in contact with syndicates or other deals that require hundreds of thousands to play.If one struggles to get $10k, or $5k, or even $1k for a seminar - the best bet is to keep saving and learn in the school of hard knocks.
