Are investments in Greece prior to 2013 applicable?

I made my investment in Greece in 2013 before the Greek Golden visa law. The properties are still valid, but the investment was not above 250,000 euro. Can I only make an additional investment to reach the 250,000-euro threshold, or do I have to make a full 250,000-euro investment again?

In order for a property purchase to be included at the applicable golden visa legislation, the purchase should be after the legislation was published and the contract should be included explicitly relevant clauses for the golden visa procedure.

You have to make a new investment again.

If the property price was paid by bank transfer or bank check (not cash or other ways), it could be possible.
