If it's a condo, check out the financials of the condo association and be absolutely sure they have money and they have a good leadership team in place such as a board of directors or management company.

If you have a law school nearby, go talk to the housing director and ask if you can advertise on their facebook page, or website or at least on their bulletin board.Once I discovered law students as tenants, the angels sang! 

I first advertised on the law school's facebook page via the law school housing director (university was next door), then if no bites from there, I'd list on Craigslist.  

Unfortunately, when the director of the agency that dealt fairly retired his successor was just as unreasonable as the directors of the other agencies.

If you're not within walking distance, then you need to be cheaper than the options that are closer.To target law student specifically, contact the law school and ask for the housing director. 

I inherited my father's condo in CT and am fortunate that the President of the Board of Directors genuinely cares about the complex and has kept up the maintenance as necessary.

For us, the law school had a facebook page, and after I went and met the housing director for the law school, she was happy to advertise our vacancies on their facebook page. 

I developed a relationship with the housing director for the law school at the university next to our building. 

The director finally told me to send his boss an email.

I'm currently working in administration for a privately owned family medicince practice as the Human Resources Director and Payroll Administrator.
