Comps: 1) You could go to the Jefferson County PVA website and look for properties similar to yours that have sold recently. 2) Look for properties for sale in your area that are similar. 3) Realtors provide a CMA (Comparative Market Analysis) that factors in solds/active properties in an area by computerized analysis. 4) Get an appraisal done by a professional appraiser.
Need to sell now: 1) I have investors that will buy and close on your home next week IF IT IS A DEAL. 2) Aggressive pricing. 3) Are you packed and ready to move? 4) Is your house in ready to show status? 5) Do you have all the paperwork needed to sell filled out? 6) Do you have pictures and description of your house for advertising done?
Websites: Craiglist, Trulia, Zillow, Yahoo, Facebook, Oodle, Yast, Military.com, Backpage, Kijiji, Courier-Journal.com, Youtube, FSBO, AOL, Forsalebyowner.com, Owner.com (they say that 80% of homes are sold via the MLS), FSBO.com, Homebyowner.com.
Just Google "for sale by owner" real estate, there are lots to choose from. These all charge a fee to list your property on some websites, give you some pictures (that you take), a sign and other stuff. YOU STILL DO ALL THE WORK.
You might want to call a Realtor and discuss your options also, we work in this business every day.
