Dutch Housing Market:
The average cost of a house five years ago was EURO 137,000. Now, a single-family dwelling averages between EUR 240,000 and EUR 250,000.

This PDF has a whole lot of data to digest:

The house price-to-income ratio has stabilised in the past few years, although its level is still high from an international perspective. The effects of rising house prices on affordability have been mitigated by favourable financing conditions. While the average housing cost-to-income ratio for homeowners has been quite stable since 1995, there seems to be a dichotomy between movers, who profited from the earlier house price boom and have surplus value, and starters, who have no surplus value and fewer financial buffers.

One thing for sure about Taiwan, low interest rates, like 5% for mortgages, will surely lead to higher prices, as people can afford more.

More thinking later.
