A weekly roundup of recently sold residential properties in Manchester, New Jersey, published this month by NJ.com, might seem an unlikely starting point for a briefing on the UK property market. Yet it throws into sharp relief a structural difference between the US and UK systems that matters enormously to British investors, landlords and developers: the speed and granularity with which property transactions are reported. In New Jersey, individual sale prices, addresses and dates are published within days of completion. In England and Wales, by contrast, the Land Registry's Price Paid Data typically lags real-world completions by six to eight weeks, and full market analysis often takes quarters to catch up with reality on the ground.
