Is this normal or am I doing something wrong

[Brandon Metz]

Good Morning Bigger pockets,

   I have recently put up for listing my first duplex. This property has been made into about as turnkey as it gets so i have no concerns, However i have one problem. I've received about 15 inquires and the property has been up just over one week. I always reply with a a few sentences thanking them for showing interest in my listing and i would like to have a quick phone discussion with them before showing the property. I do this so i can phone screen potential tenants before wasting time on a dead end. Out of this process only 2 people have ever responded back to my message. Is this normal or perhaps im wording things in a way that scares them away?
