【明報專訊】SINCE the government's upward revision of the special stamp duty and introduction of a new buyer stamp duty, transactions in the property market have plunged. Over the past weekend, only 16 units were sold in the primary market, down 80 percent from the previous weekend. And the secondary market saw only 10 deals in the 10 major housing estates on Saturday and Sunday, a record low in nine months. However, while transactions have plunged, home prices have not dipped appreciably.
