jonb: My general point is as a country we seen to spend about the same proportion of income on housing regardless. I would rather a higher proportion of that spend, which we will be spending anyway, went as tax rather than mortgage/rent ( soneone elses mortgage) to the banks. Similar to parts of US where houses are cheaper but property taxes are higher.
The US does have some anomalies that contribute to that such as much longer fixed mortgage rates than we have. It is common in the US to fix your rate for 25 or 30 years, which obviously has a significant effect on household budgets - the rates are usually quite low. My brother in the US has a fixed rate less than 4% for 25 years IIRC and I can find 3.99% fixed for 30 years on line right now.
Additionally, mortgage costs and property taxes, repairs and so on are tax deductions from your annual income tax calculations for Federal tax.
Taxpayers can deduct the interest paid on first and second mortgages up to $1,000,000 in mortgage debt (the limit is $500,000 if married and filing separately). Property taxes (i.e. rates) are given as a tax credit on your income tax calculations too.
