(RECAP: Home-price increases moderated in much of the U.S. in the third quarter as more properties came to the market and investor purchases declined. The median price of an existing single-family home rose from a year earlier in 73 percent of the 172 metropolitan areas measured, the NAR said in a report today. Sixteen areas had gains of 10 percent or more, compared with 54 areas in the third quarter of 2013. Prices declined in 47 regions. The median price for an existing single-family house in the three months through September was $217,300, up 4.9 percent from the third quarter of 2013.)
