MT Shark Tank - Undeveloping Commercial/Residential Properties

This thread is somewhat the opposite of Mariner's Developing commercial properties thread from earlier.

I’m looking for some business advice around the idea of taking blight and rehabbing it back to a natural state. I have two businesses that can be involved. One business is for removing old decrepit buildings or cleaning vacant land that is littered with junk. The second business is for performing the land rehab. I'd strongly consider trying to return the land to its natural state with native plants. Ultimately the land clean-up would be focused on making it marketable for sale.

I’d want to start with small properties to minimize costs and serve as learning opportunities. Mainly learn the ins and outs of property removal and clean-up. I'm thinking initially I would seek ownership of the property and then over time maybe offer clean-up/rehab work as a service other landowners could contract. This part of the process I am really unclear on how it might unfold.

Is this an idea that is next to impossible to make money from? I sit in front of a computer all day with no experience in what I am thinking. I won’t be quitting my day job anytime soon to do this, but I'd be in favor of putting the idea to the test initially as a side gig.
