A few of them also mentioned that they don't really expect this to affect the housing affordability in the county, but do believe that STRs can affect the quality and integrity of the neighborhoods in the county which they want to preserve.  

You’ll want to invest in areas that have tenant interest but also aren't on the extreme end of neighborhood quality—this means avoiding the very toughest spots, where turnover can be high and managing tenants can be difficult.

Curious to hear others thoughts: Do you believe experience is the primary factor, or are there other qualities that matter more?

Quite prudent to stay away from such lack of quality in regards to REI agents.

I'd hate for a temporary dip in the quality of the tenant pool to be giving my landlord "spidey sense" false alarms on account of taking an extra month or two to fill a unit.

You are being very conservative to avoid making mistakes, and that is a rare, admirable quality in real estate that is often undervalued. 

@Cole Bossert I think @Sarah Kensinger and others have touched on the biggest qualities, especially communication.

In my understanding, I thought most high quality syndication opportunities were open to accredited investors only.

You will learn the cost of maintenance/cap ex and how tenant quality plays a big role.  

Are their listings detailed with good-quality photos?
