Help, why so much interest in my property?!

[Chris Lieder]

Hi guys, I've got a duplex that I've owned for about 5 years. I've got a renter moving out and so I've posted that unit on Zillow/ Trulia/ Hotpads. Within just a couple of days I have over 50 interested people in the property, probably more! I've got literally dozens of phone calls and voicemails, I've actually just stopped answering the phone. I can't possibly follow up with this many people to find a good applicant.  My question, what is going on here? Is my rent too low?  Am I doing something right or wrong?

Here's the listing:
