New STR property expenses?

[Curt Bixel]

I have a duplex in Columbus, Ohio, which I am planning on turning into a short term rental. It is a 100 year old home, but it is in good shape. The kitchen and bath were remodeled this summer and the entire unit was painted. I plan to make this a STR and do the same with the other side when the tenants on that side move out.

I am curious about expenses.  I am budgeting about $6000 for furniture, bedding, towels, etc.  It is a 3 bedroom 1 bath apartment.  I imagine there will be some more expenses for deep cleaning as well as a punch list of items that need to be addressed after the management company does a walk-through.  I figure about $500 for that.  I imagine there is a "start up fee" for things like new locks, pictures, advertising, permitting, etc, so $1000 for all of that.  I also know that I will need to budget for gas, electric, water, internet, and cleaning between guests.  

What else might there be?  Do I need a different type of insurance from what I had when it was a long term rental?
