Someone says below:

"The problem is, Not all houses even have deeds, in the communist times everything belonged to the state therefore the only way to prove ownership of a property after the fall of communism was to present the original deeds of your grandparents etc. dating back to the 1930s-1940s. Without this the property has an 'assumed deed' which prevents the current occupants from being evicted, but, not able to really sell the property. Its easy for a Bulgarian to go into the property under a further 'assumed deed' but when a company wishes to have 100% clear title- so much more complicated"

How many percentage of properties in there only hava a "assumed deed"?

If I try to buy a property, how do I know the owner has a "real deed" or a "assumed deed"? (I talk about the old properties--house with land, not newly built properties).
