So anyone who advertises or uses ANY marketing technique, can really advance businesses here. 

Look, this example may indeed be true, though morally “questionable”.

Based on what you have explained here and assuming that all of it is true, than you really only have two options to get it rented1.

This isn't true. there are lenders that do 80% cash out refinances - DSCR isn't the only loan type you can close in an LLC to get 80% cash out...and there are many lenders where investors can get 0% origination fees --- keyword here is "lenders", not brokers.

I find that the good brands hold color quite a while, I prefer BEHR marquee from Home Depot, a true one coat paint (for most colors).

I'm not sure if its true.

For most investors, to provide true separation would be cost prohibitive (between $10k-$15k). 

If we bite off people’s heads when they admit disaster, it suppresses legitimate issues with these techniques. 

It helps being willing to talk to sellers/get on the phone and talk to folks in the real estate space in general but the most important thing in my opinion is being an honest and true person.

Not true.
