Monthly mortgage payments make up 30.4% of Czech household income, and they are the biggest burden for households in Prague who send nearly three-fifths of their income to a bank monthly, the Czech Statistical Office reported. Households in the Ústecký region spend one-eighth of their income to repay their mortgage loans. “The mortgage-to-income ratio in Prague is much closer to what we see in western European countries,” said Cyrrus analyst Hatlapatka.
