And note that there are economists who argue that establishing such a blanket threshold to define housing cost overburden, be it 30 or 40%, is not useful because it depends on the amount of total disposable household income and the cost of living in different places. Meaning that a household with a 800,000 euros of income per year can probably afford a 40% housing cost in an expensive city, while a household with a 16,000 euros of income per year probably can't afford a 30% housing cost in an inexpensive city.
