And then we also get families visiting college students (we have 3 large ones like Duke), and tons of travelling nurses (our medical industry is large here).

Traveling nurses and other professionals search this area often with the considerable amount of hospitals, medical facilities and corporations in the surrounding cities. 

Traveling nurses and workers in the tech hub are common answers, does your market support the demand for them?

Sorry, VERY wrong again. the most sought after individual's for lawsuits. the sweet spot are your average investors (neighborhood millionaire) {contractor, lawyer, doctor, nurse, etc) who just turned the corners with assets, of 1 million to 3 million who now has tons to loose from just the threat of a lawsuit let alone an actual judgment.

I have a MTR/STR in Arlington, we have hospitals nearby for travel nurses and plenty of tourism that brings people to the area.  

For example, if you're looking for travel nurses, you'd note that your listing has blackout curtains, a white noise machine and near hospitals (those are important details for them).

Let me give you an example, you have a client that works 7pm-7am (think of a nurse or doctor), they tell you they are really only available to physically go and look at properties 8a-10am or 3-6pm.

Many owners covet the traveling nurse which is known to pay a premium for MTR’s without a blink of an eye. 

Could be travelling nurses near med centers.  

I'm right there with you over 39 years as a Nurse and I don't know nothing else.
