June was the third straight month of slower sales, and the lowest pace of sales since the seasonally adjusted number for January. The pace of sales is now 9 percent year-ago levels, and was down in each of the four regions of the country.

The median home price, which reflects the point at which half the homes sold cost more and half cost less, edged up to $231,000 from $229,000 in May.

But that marked only a 0.9 percent increase from a year earlier, which is the smallest year-over-year gain in home prices since May 1995. As recently as October, prices had jumped a record 16.8 percent from a year earlier due to tight supplies and bidding wars among buyers.
