Assuming the stat is correct, home ownership rate in Croatia is almost 90%. So apparently most people can manage to buy a home, and the condo being barely in reach of two highly paid professions in the capital is an anomaly (right downtown, on the water?).
Edit: Interesting thread on high home ownership rates in those countries: http://marginalrevol...ul-country.html
This is where the real life analysis paints the true picture. I don't have a single family member in Croatia that rents. I only know of one family member that has a mortgage. Sounds pretty good right? The reason you have very few renters is a lot of individuals cannot afford to rent; therefore, they live with their parents in crammed quarters. The reason very few people have a mortgage is rates are high and incomes cannot support purchasing real estate; therefore, most people wait to inherit family homes and condos or the proceeds of such so they can buy something else.
Even though I can only think of one family member that has purchased a property without using the proceeds of an inheritance sale all my family members "own." One example is I have three cousins that are all married that all have two kids and the three families share a 1,200 sq/ft home that was built by uncle.
Many other factors such as during the communist regime many people (with the party) were assigned free condos and then they passed those onto their kids so you often have individuals with very low income but significant mortgage free real estate assets.
It's really weird. 90% of people own, almost no one has a mortgage, and things still suck from an economic affordability angle. Growing up in Croatia my parents both has professional jobs, they had a car, we had a house (no mortgage) and they still left for economic reasons - best decision they ever made. Health care, education, etc., is all half decent in Croatia so few people leave for those reasons.
