Other areas have county administrators, these admins are non-profits and they are usually engaged in other social activities, housing assistance, utility bill assistance, health and welfare matters, education, credit counseling, etc.

Plenty of videos online.

To be fair, the support people are nice and they do respond with videos and instructions.

Ideally, I'm looking for a general contractor or developer willing to engage in a revenue split arrangement or someone interested in a long-term land lease.Does anyone have advice on how to navigate this situation?

Have your agent verify all pertinent information and provide video walkthroughs of the property and community. 

I've been watching alot of YouTube videos and I would be doing a level 2 rehab in which they say will be roughly in the $20 - 30 per sq ft.

I'm definitely listening to as many podcasts, watching BP youtube videos, searching the forums for specific topics and of course connecting with those who are already in the game. 

I would also do a walk through, video and pictures.

I interviewed 2 investors with big portfolios in Baltimore recently and can share that video with you if you would like a more in depth explanation of where to invest and where to stay away from just DM me 

I would not engage with this ex-tenant.
