Here in Park Forest property taxes range from 4500 to 6000... non occupants is more.

I don't have any experience in vacation rentals myself, but I would imagine that vacancy and occupancy are, in most markets, concentrated to a few weeks/months like you saw on AirBnB.

What about current owner occupants with high equity who bought at least 10 to 15 years back?

My mentor did say that the company he has running his properties took is occupancy rate from 94% (where he ran it himself for 3 years) to around 70-75%.  

At that, 1 bedroom is used by the house manager,  the other 8 are double occupancy,  so 16 people,  at $100 per week.
