That brings up a host of questions:What if I don't like how they are managing the property? 

I think out of over 500+ guests, we have maybe had 2-3 terrible guests (nothing major, though), and around 5-10, I would never host again.

What other expenses are there (snow removal, lawn care, internet, utilities)?

While the wealth of knowledge and experience on BiggerPockets is wide and deep, I would not trust a decision like this to the internet, I would ask you CPA and if you do not have one find one who specializes in this sort of thing.
