Be careful when buying secondhand property in Bulgaria. Make sure that the land is not owned by a family or group of people because each and every one of the owners will need to agree and sign that they are willing to sell the property before you can buy it. In reality this is not easy and can delay the transaction beyond what acceptable.
If its new property dont be fooled by the eastern promise. Many people have been buying over the last few years hoping to make quick profits. The window of opportunity is over I feel here. There are better places to invest in property.
