I'm glad someone is finally covering this. When I did a bit of independent research on a few areas and downloaded land registry data for new builds versus non new builds, the difference between the two (and sizeable falls in costs of new build sales over the last two years) was quite amazing. It definitely skews the reliability of 'house prices in Boroughbridge rose 6% in the last year' type of thing you see on places like Rightmove. I've given you an example area that's chocced full of new builds - in fact, Rightmove is saying the opposite! Now what's happening is dozens of them are trying to sell their secondhand newbuilds and hardly anyone's buying them, which is quite sad really. It's an okayish area.
I'm not looking for a bun fight (done enough fighting elsewhere this week, teehee), just to share the article, on which you can make up your own minds :)
