Rehab or replace? How to start redeveloping land.

[Scott Bell]

People always talk about rehab and rent or flip. What about replacing a property. I listened to a podcast about real estate development, now all I see are the properties that I can replace. Old mobile homes, barely standing stick builds, and empty land. 

What are some good resources to learn this model of real estate? old podcasts, books that are recommended, people or groups to join?
