Why is buying a home so expensive?

In my country buying an apartment is very expensive for a young family, and buying a house is extremely expensive. It is getting harder every year. Almost all my friends and acquaintances purchased a property with support from their parents. The entire buying process is expensive. In the end, they have a property and mortgage that they must repay every month to the bank, not to mention childcare costs and necessary living expenses.

Many people buy property far from the center of the country. It's much cheaper, but they waste a lot of time commuting to work through traffic. Sometime people can't pay their mortgage and are forced to sell.

I know other people who have several apartments. They inherited apartments or bought apartments a long time ago when buying a property was cheap. They rent out their apartments and have a good monthly income.

It's so sad and I hope this situation will resolve in the near future.
