with regards to buying off e-bay, a thought has just come to my mind, and a quite important one at that.
You are required by law to have a company in BG to buy houses which are situated on a plot of land. For apartments you are not.
So lets say you win an auction and pay the money, technically the property still does not belong to you (if you do not have a registered company and lawyer completing the deal for you), that to me seems like a very large risk to take given the amount of properties here in BG that have incomplete paperwork. A good lawyer would recommend not paying the 10% deposit (required to secure the property, if buying from within BG) until the paperwork has been thouroughly checked
E-bay may work for some, may not work for others. Buying a property is not like buying something cheap/second hand or junk that someone no longer has a need for
