@3BSHKATS so much to unravel in your complex post.
The 200% increase in house value has to be adjusted for inflation and other factors relating to location, demand etc. Your industry pay standards has to be adjusted for changes in demand and nature of the industry. Global inflation is high due to many factor the most obvious being the war in Europe and over-population including water shortages and climate change.
It is unlikely that even in the medium term inflation will stay as high, and waiting 15 years to assert a norm is pointless because it ignores likely near term scenarios as they play out. The fact is a real interest rate of about 4% over inflation has always been what it takes for markets to operate. Of course this is average and generally higher for retail loans, less for public works loans. It is not about looking back, it is about an assessment of risk-taking by lenders.
Affordability is what individuals work with. Markets are what the world works with and cannot be avoided. Individual circumstances will dictate how we engage, and they obviously vary. Governments rely on voters so will try to manage the story and as far as they can the tools such as central bank rates. In the end, economics like physics cannot be denied. So we navigate our lives as best we can knowing that artificial market interventions cannot be relied on.
