Seeking out poorly marketed rentals for owner financing opportunities would be the other faster option...maybe checking craigslist or yardsigns in the area you want to buy.  

Yeah they'll write the listing (probably poorly) and hire the photographer, but as far as I know they're not going to order a couch and assemble a dining table and stock the kitchen and all that jazz so you've gotta do that either way.FWIW if you're really intent in not traveling to set it up, I did hire someone to do that part for me in one of my properties where some family health issues came up and I really couldn't get away for a week. 

I want to move my main company's office and employees (wedding video production) to Denver where I live. 

2nd post, you sure this isn't product placement : ) 

Some of it is finished and some is not and most in poor condition.

Lots of lenders have FHA loan products available.  

The property management company I hired for my rental has had very poor communication from the beginning.

Bunch of family members have used this product.

This is such a broad question, but the mistakes that lead to the worst outcome were poor tenant screening for my rentals and even air BNB's. 

Of course you also have "Rich Dad Poor Dad" and the other Robert Kiyosaki books.Hope this helps!
