If it was GreeceRealEstate.com than you'd have a good domain with potential buyers. Also all of the other CountryReal.com's that have been registered have never been sold that I can find and most likely never will (I checked on NameBio.com & DnSalePrice.com).
As you can see "Greece Real" gets under 10 searches a month out of the 11Billion+ searches Google get's in a month. So your chance of finding someone interested in buying it are slim to none.
