Here is just one more piece of evidence pointing to a slowdown in the property market.
This chart tracks the number of transactions paying stamp duty. As you can see, the numbers have been declining sharply for the last couple of months.
One quick word of warning; this data may include some commercial property transactions. Normally, these kind of transactions account for about 10 percent of the total. However I couldn't get a clear understanding of whether this particular series included commercial property transactions or not.
