How would you respond?

Have a vacancy at my sfh and posted it on Craig's list. 18 minutes later I get this:

Hi there , was wandering if the apt is still available,and move in ready very interested , would like to make and appt to see it ASAP. Please contact me at your earliest convenience. Looking for a place to move ASAP.

And thats with a phone number 18 hours away... This rental is a sfh, he says apt. Just posted ad, he asks if still available. He mentions asap more than once which I've seen people on her say is a red flag.... My gut is calling this bull.

Your thoughts? How do you respond?
