I would say it's a high risk / high reward play.

You can find value but if you are only buying one property you increase your risk. 

There are alternate options that are more expensive and higher risk but not reliable.

Issues and concerns over appreciation would be more or less 'at the risk' of whoever agrees on taking any given property.

My view of holding any of their stock would be different if I were buying in as a non-agent, likely wouldn't be on my radar...but I'll have to balance that risk/speculative gain for myself over time as I'll at least have a hands-on feel for day to day operation, if not the big picture finances of the company. 

Thanks @James A. for the advice, I'm definitely leaning towards the partnership route both for the financial reasons as well as the support in splitting the risk/workload.

Even though it's NNN they still perceive risk so what better property to NNN than your own. 

So, if I default, he is at risk of not getting paid.

My lease specifically states tenant responsibility to reduce the risk of mold and holds them liable for causing it.At this point, you let one kid out of the lease, so that probably made things worse and lead to the other parents believing their kids should not be there. 

Hi @Chris Mason narrowing down an strategy is exactly what I'm trying to do that's why I need to gain more knowledge about this subject, I'm a very analytical person and just like playing chess I like to analyze all the scenarios, always thinking 1,2,3,4,5 steps ahead then set up all my pieces  in place and then go for the checkmate (In this case landing a good deal, lowering my risks and maximizing the profit or cash on cash ROI).
