Your expert input is greatly appreciated.Down Payment/Option Money  Research found - 1%, 2.5%-7%, $5K, non refundable, partially applied to purchase price. 

I am looking into first creating a non-profit for purposes of acquiring, rehabbing distressed housing; then renting out rooms to seniors/55+

Non owner occupied you pay taxes on the profit of a sale unless you 1031 exchange.  1031 has some challenges but there are experts that can help.

By the time its out to general public its already old news.

They will take more non conforming loans and lend on the cash stream of the property/ asset. 

Non-fiction - no end to what I listen to here.

They govern home inspectors in the state of Oklahoma, and can provide you a list of licensed commercial inspectors.

Don't go trespassing just to find out about the trash cans, toys, flowers, etc, but my understanding is that if you are standing on the public street or on the public sidewalk, anything you can see from that location is knowledge you can use. 

Let's assume desirable neighborhood, close to public transportation, etc but no chance of ever qualifying for standard financing.  

So what are the regular publications that you use, or web sights that you visit?
