Interesting but I don’t think having 40% downpayment solving the issue because banks, speculators and foreign investors will have the money to exclude normal buyers.
I am in Switzerland an 20% downpayment is a must. Secondly you can only take money out of your retirement scheme for a move-in house. But still supply is highly limited making prices explode. Most people I know have about 500k to 1 Mio in debt (about the same in Euro).
As rent prices seem to go up as well the problem aggravates for low income people.
What else is Netherlands thinking about doing?
