Advice on where to advertise investment property for sale

[Jobie DeVinney-Walsh]

We have 3 rental houses in Charleston, WV for sale. With almost 46% of households as rentals, the Charleston market is better than it appears on paper.  

All these  properties have been almost continuously rented since 2001. There is little or no repairs needed on any of them since we have worked hard to maintain them. These are pretty much turn-key operations, with tenants and a management firm in place.

 Charleston doesn't have many people looking for investment properties (or my realtor isn't marketing it right). My sense is that I need to promote the property beyond WV.  Any suggestions on where to advertise them?
