Most of the taxes and legal fees are based on the "objective value" of the property.
This is the tax authorities' assessment of the value of the property.
However, it is a long-standing tradition in Greece, to reduce the declared value
of properties to minimise fees and taxes. The objective value is usually significantly
less than the purchase price, and is finalised by negotiations between the tax authorities
and the purchaser, or their lawyer or Notary Public.
