How can you beat a potential market of 147 million people? That's how many visitors eBay claims to have every month.
Did you know that you no longer have to use the auction format? eBay now gives you the choice of a classified ad as well. It's $150/month. Here's the link for more information: http://pages.ebay.com/realestate/homesellerguide.html
There are no value fees or commissions on the sale. You generate leads. In the auction format, the sale is still not a legally binding contract. It's just an offer.
In the ad format, you list the asking price and when buyers fill out a contact form, it is emailed to you. eBay is just another form of advertising. It doesn't take the place of a Realtor, and Realtors may place their contact information within the ad format classifieds. For more details see: http://pages.ebay.com/help/policies/real-estate.html
We have used the auction format and gained several leads. Now we're trying the ad format to see if we can generate some interest in hard to move lots.
I think lots of description, use of color and larger type and several photos helps the ad. You can sell timeshares, land, residential, purchase mortgage notes and more.
Florida is the top land market on eBay right now followed by California and Texas. http://pages.ebay.com/realestate/landforsale.html There are only 55 listings in the land finder for Florida homesites right now. eBay claims more than 55,000 parcels of land have been sold on eBay since they started including real estate.
Only 2017 residential homes are listed. 462 in Florida. There are also guides on buying, selling, financing, staging your home and many ways to search
I think you'll find it and interesting search just poking around.
