Joseph, the best method for you would probably be the MLS or sites like realtor.com etc.

I own a duplex property (I do not live on site) and I'm renting out the 2 bed/1 bath back house.

While both involve finding and properly securing a site and bringing it to full entitlement, the ground-up process includes the land piece but gets way more involved and complex to execute.The full "Monty" for ground-up development needs to include financial literacy, an explanation of metrics, and how they work.

But I also love the idea of investing in real-estate and utilizing its tax benefits I have read around 10 ish books or so and the one I am reading right now recommended this site I am looking for some advice of things I can do to either prep for an investment into real estate and or do right now.

Spreadsheets/Templates:If you don’t want to start from scratch, sites like BiggerPockets and others have pre-built templates you can use to run your numbers and track your expenses.

I couldn't find anything too specific on the site.

We live in Lakeland, TN 20 miles from the Blue Oval site and I recently had a new BO employee rent one of my homes with a potential to sell in the Spring/Summer of next year.

There are sites out there like passive pockets as well as this site where you can find out a lot from people who have invested with that fund.

Seems like 130 units is a beast to manage, I'd love to hear about your on-site management systems and "experience management" process to stand out amongst the fierce competition in the smokies. 

Any other major syndication site has restricted sold data so it will be incomplete.
