In Bulgaria , there are such terms as "tax estimation price" and "purchase price". The "tax estimation price" is for the purposes of real estate taxation and is much lower than the actual selling (market) price. Most of the Bulgarian property owners (vendors) prefer in the title deed to be written the "tax estimation price", not the selling price that the buyer has paid. So because of this practice there might be discrepancies between the price You pay and the price written in the title deed. Property in Bulgaria is not responsible for that! But if property buyer insists on writing the purchasing price in the property title deed, he should inform us in advance in order to negotiate on this with the vendor of the property.
