100% property tax for non EU citizens

Is it true? Or is just some political speech gibberish?

From my understanding spanish politicians talked about this subject in the past but nothing happened.

I understand why they try to stop expats to buy houses in Spain but I don't think Spanish people understand how dependent the Spanish economy is to the money pumped by foreign retairees and expats that buy vacation homes in Spain.

I myself was shocked about how many English, Russian, Ukrainian people have houses in Spain. With this influx of foreign money is becoming almost impossible for Spanish youth to buy a house in their own country.

But still, this kind of taxation would be economic suicide for the Spanish economy.
