After 9 months of trending towards smaller price declines, this is the second consecutive month in which the index shows price falls accelerating, from -4pc in June, to -4.6pc in August.
Why are price declines accelerating again? It might have something to do with the increase in sales taxes at the start of July. With taxes taking a bigger bite, vendors might be having to accept lower offers.
After the latest decline, property prices on the coast are now down 22pc since August 2007.
