Hi Bonnie,I was hoping to get a quad with 1b/1b close to a large hospital, which would allow me to serve the medical professionals.

$15,000 gain, $0 investment Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Look into local business groups, professional associations, alumni networks, etc.

I've tried everything and done everything "right" according to what everyone says (professional photos, changing rates, premier host, updating listing frequently)...well this was a surprise..."

Hey Lori, Yes, saving your receipts for local meetups could potentially provide tax benefits if the meetups are related to your business or professional development. 

A lot of real estate professionals (including myself) give thoughtful responses at least in part to drum up business.

I read this quite often: 'should I self-manage my property or hire a professional property manager?'

As far as the reporting goes, the rental income and losses will most likely be reported on your Schedule E - speak with a tax professional who has expertise in real estate.

My realtor was super patient with me and was super professional though he probably ended up making $1.50/hour with all the hours and phone calls he had to make to close the deal. 

These are professionals with additional training and a stricter code of ethics.
