The Evening Standard ran a poll that found that 50% of Londoners were opposed to the house price boom. Of course. They're the 50% that aren't owner occupiers and have no prospect of being so - many of them singles. And neatly avoided by the banks in the media fuss about their looking at gym memberships or money spent on takeaway pizzas was the one key indicator they will be looking at when granting a couple a mortgage - how stable their relationship is.
For it's only now couples in London who can get on the housing ladder - with 4.5x joint income mortgages. Singles would need a loan of 9x their salary. So the banks will be evaluating the stability of the relationship; how long they have been together, whether they intend to have children and so on. St Paul may have declared 'marry or burn' but the real choice for young London professionals is now 'marry or live in rented accommodation all your life'.
And this of course is by far a more powerful incentive to marriage and family life than the £500 tax bonus that Osborne can offer. The law of unintended consequences strikes again ... but this time for the better?
