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

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.

You should visit Beers and Deals in Little Italy hosted by @Rich Somers as well as Ales & Assets hosted by @Mel Adams.

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

Orlando is the most visited city in the USA.

You will be competing with people who have 'boots on the ground' and can visit any property owner with short notice.While wholesaling from afar is possible, it is recommended to begin closer to home.

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.

In your case and my case in the example sited the insurance rose higher than could reasonably be forecast.  

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.

I will definitely look to add more when I visit next.
