If you are looking to buy a rental property then it's just easiest to find a realtor to help you find the right property. But if you want to find the property by yourself, then you can use such sites as: http://www.craigslist.com, http://www.ziprealty.com or any of the big real estate brokerage websites--they usually have MLS search engines available for free as well (e.g. http://www.coldwellbanker.com, http://www.remax.com, http://www.prurealty.com, etc.).
you need to be much more specific... Are you from Pikeville or is that where you'd like to find a rental? How many beds/baths do you need? What is your price range? What amenities are important to you? Please re-post your question.
