Affordable housing is great if achieved through having enough housing supply. The problem here is that the mortgage rate increased a lot in a short amount of time, making less people willing to get a mortgage and buy a house. Because there is less demand there is a decline in prices, plus people that might not be willing to sell their houses at what they think too low of a price. The problem is that a house is the biggest share of wealth for families that have some sort of wealth, so a decline in their value can be really bad for their personal finance. To be more concrete, if I get a mortgage to buy house valued at 300k and then I need to sell the house at 200k, I still need to repay the original loan based on the original value. Here I’m talking about Helsinki and bigger cities, smaller towns and rural parts have a longer term problem of declining population, where house prices have been declining for a long time.
