You decided to become a real estate agent.You went to school, bought your books, passed your exam, got hired by a broker, ordered business cards and took a head shot.

That is something I would for sure have to look into as, according to your post, it seems like the timeline for mid-term rentals kind of lines up with the amount of time that we would be gone each year, which would work out well and probably require less of a hassle of trying to maintain the property after each stay for Air BnB.

Before we sold it we hired a management company to reduce the burden, but even then we decided to sell and walk away. 

Similarly, My mother-in-law went to live in assisted living homes rather than us having a guest house in the backyard of our current home where we could have hired a nurse full time to be here with her to take care of her at our home.

If you hire a Property Manager they can sometimes help arrange lawn and snow removal service.  

You hired a PM so they can handle these types of issues.

If you have no clue what you're doing, hire someone. 

We never hired a manager because it simply would have taken too much out of our profits.

Evict her for creating a health hazard--closing off the deck blocks an emergency exit and stops air circulation which allows mold to grow easier, plus it is altering the house.  

My 8 year old turns air bnb with my wife.
