Now she is messaging me and saying the outlet for the dryer sparks, looks like it wants to catch on fire.

if it is an actual management company, call the main number and ask to speak with your manager's supervisor, managing broker, owner, whomever. your assigned manager may be on vacation, ill, otherwise unexpectedly out of the office, dealing with an emergency today and hasn't seen your email, text message, or voice mail message from this morning yet, etc. etc. etc.if it is a mom and pop shop operating out of the back of their pickup truck (or a spare bedroom in their house) and they really are just blowing you off, check your contract. there is likely a provision for a default (not calling you back may not constitute default). it'll tell you what to do if you believe your PM is in breach of contract.

All outlets near a plumbing fixture are GFCI. 

Another is GFCI outlets in all "wet" areas.

I would be able to afford to pay the excess expenses of the negative cash flow as well as any unexpected annual repair cost. 

And you will have loads of permitting to deal with since you are talking about food, so be prepared for delays and unexpected costs. 

We do have a comprable ad on CL.I guess we will have to consider reducing the deposit, but that makes me concerned.Actually this looks like a rural area, but it is only two blocks from good jobs in retail outlets like Meijer and a mall.I will have my wife add more flowers.

Part of your margin on calculating your flip has to be to absorb unexpected expenses.  

One of the unexpected nice benefits of that is that it allows me to prompt any/all guests to complete a check-in form that includes entering their email address, something I would never get through AirBnB because they have a vested interest in keeping guests and owners dependent on their platform.  

You never know when an unexpected cost will come up, or if the market shifts and you have to pay extension fees on the loan.
