Compared to other popular countries such as France, Italy and Spain, Croatia is still very cheap. You can spend your holiday in top bill accommodation, dining in the best restaurants and still pay very little. This may change in the near future, but so will the price of your sea view villa.
Real estate prices are 30% below market prices of France and Spain.
Asking prices have dropped and (mostly newly built) properties are offered at discount prices due to financial crisis. It is definately time to buy now.
