I’ve just learnt about a British couple in Valencia who bought a bargain home in La Viña (Valencian Community) from La Caixa bank, and have now been hit with an extra €12,000 “bargain tax” they can’t pay, and fines for late payment. So it’s still going on, and buying from a bank doesn’t seem to reduce the risk. In the Valencian Region, in particular, you have to be careful when buying a bargain. Just to make it more complicated, the bargain tax varies by municipality.
This is truly appalling behaviour by the Spanish tax man
