Yeah, the value of nice large houses even 15-20 minutes outside of civilisation is much lower around here. A house that would be £1.5m+ is under £1m simply because its not near good schools, train lines or civilisation.
There are loads of lovely houses around us we could afford and would be great...apart from the above.
As to your last point, I can't help but feel that to keep the bubble going they will simply make mortgages a form of rent. You can take a mortgage out that you will never pay off and if you die then the house is sold and the bank takes their share back. Would allow people to spend 10, 15x multiples of their salary on a house because it wouldn't matter if its over 50 years.
