You're right on point using all the free websites to advertise (Craigslist and Postlets pretty much hits them all). One question, have you renewed your Craigslist add to get it bumped back to the top? Doing so could go a long way in getting those inquires flowing again.
Also, make sure that your ads, especially on Craigslist, are professional and detailed regarding property info, rental criteria, and include high quality photos. Doing so will help unqualified leads to pre-screen themselves and attract higher quality tenants overall. If I were looking for housing via Craigslist I would be very wary of any of those two-sentence ads you see with no photos and poor grammar.
With all that said, dropping the price down to $1195 isn't a bad move necessarily, but if I were in your shoes I wouldn't feel in a rush to do so just yet. The rental market demand in Nashville is unbelievable right now, so as long as you are offering a clean/safe property and in the ballpark of what would be considered ¨market rent¨, you should be just fine.
