Wouldn't mind public feedback on my venture, either :) 

I am interested in owning and renting properties, so I can have a minimum passive income of100,000/year.My passion is public service and community organizing.

You got it - they started renting it to the public at way below market rents just to have them full. 

The Securities Exchange Commission strictly prohibits any detailed explanation of private placements (which DSTs are) in public forums.  

Maybe I can run it as a public parking lot for a while until I get comfortable on the learning curve and build a trustworthy network of local people who can do the jobs required (architect, engineer, GC, builders, etc.).I figure that the parking lot business will take very small investment upfront and will generate some cash to cover annual property tax and then some.  

As a realtor you are held to a higher standard when dealing with the general public.

Should be on public record on the county website.

Same with a rental- all costs needed to make it ready for it's use are part of the cost. https://www.irs.gov/publications/p551The deminimus pertains to a business costs but the business isn't open/ asset isn't in service with a rental until it's ready and available.  

Too complex to go into detail on a public forum...
