@Wilson Phu Bang thank you for responding. to be completely honest I think the information is from a youtube video and basically.

Most of the information you're looking for is already in Youtube for free, in addition to legitimate forums such as biggerpockets. 

Sean Rakidzich and his Youtube Channel Airbnb Automated.

Here we look at the history of housing price index (log-10 scale) and comparing it to the interest rate of a 10yr treasury note.Normally, across podcasts, blogposts and YouTube videos we hear that recent parabolic rise in housing prices has been attributed, in part, to a massive drop in interest rates going from the Paul Volcker era of the high interest rates in 1980 up to now, when we are in the zero interest rate environment since 2008 (excluding rate hikes from 2016-2018).

I'd also recommend a few YouTubers/Influencers: Realestate Duru - which I believe he's been a guest on Bigger Pockets multiple times and Liliinvest - She has a good series of videos taking you from the beginning of her house hack to wholesaling journey to now where she's investing in large multi-families and has gotten involved in other real estate projects. 

It also wouldn't hurt to go through the BP video library here or on youtube to see if you can dig up something that might help. 

But, I am still confused by the varying inputs I found.Can someone point me at a site or YouTube video or something that can break down the specifics of this program?  

There are many step by step tutorials on youtube that defines each section of the contract.

Been a fan of his YouTube for awhile now.

Go to youtube and search:  rent to own, lease option.
