Yeah, this is a relatively important metric for both investing but also affordability. It shows that there is an apples to oranges comparison in housing prices across markets (discounting currency differences).
When calculating the affordability of a home, the total monthly cash flow requirements (housing costs as a percentage of income) are critical. I live in an area where the rates are 10x that of Auckland. A $600k home valuation requires a ~$250 weekly rate commitment vs only about $27 in Auckland - a significant difference. It's still an expensive home by any metric, but considerably more affordable.
From a speculation perspective, an investor in Auckland can sit on a very expensive property with almost no cash flow burden, reducing the need to even rent.
