I can share your Furnished Finder link with my network of traveling healthcare professionals. 

They include Comfort Inn, Country Inn, Extended Stay Suites, 2x Holiday Inns and Candlewood.Here's the total view of employers based on my research so far:- Hospitals and Healthcare Facilities: Some search results mention the high demand for traveling nurse housing in Cookeville, indicating that local hospitals and healthcare providers are a major source of furnished rental needs.- Manufacturing Companies: The City-Data forum post lists several major manufacturing employers in Cookeville, such as Fleetguard, Ficosa, and Tenneco.

I know personally quite few Sec.8 Tenants who drive nice cars (Lexus, Jeep Wrangler), take vacations, enjoy shopping in high end malls......they work for cash and have free health care, food stamps and Sec.8 Housing.These are not legal reasons but that's not what I believe I should do.

These websites specialize in connecting property owners with travel nurses and corporate housing tenants.In addition to online listings, you could also reach out to local hospitals and healthcare facilities to let them know that you have a condo available for medium term rental.

Where these numbers are found, there is a very high rate of rent actually being paid.A little more about the area:We have over a dozen Fortune 500 companies just in Metro Detroit with huge Healthcare, Auto, and mortgage industry National footprints.

I believe my target demographic would possibly be a Healthcare worker or possibly an engineer working on a contract. 

All my units are in A/B class neighborhoods with 95% of my tenants in healthcare - nurses/Doctors and all my units are wirelessly controlled with security system, wireless door locks...

There are travel nurse agencies like Aya Healthcare who provide housing for their nurses, but many nurses in my experience are looking for their own housing on the listing sites and Facebook.On the property side of things, like Eliott said, you need a space that is attractive to nurses.

There's a pretty steady pool of healthcare professionals coming to the area for 3 month contract work.

@Dan Camp  also see if there is a local Pittsburgh FB group for health care travelers.
