ZipRealty adds agents, boosts sales

Transactions up 28% but company still in the red

ZipRealty Inc.’s closed transaction sides grew by 28.5 percent during the second quarter from a year ago, but falling home prices limited growth in revenue to a more modest 5.6 percent.

The bottom line for the growing Emeryville, Calif.-based real estate brokerage was a $2.4 million second quarter loss, an improvement from the previous quarter’s $7.5 million loss but larger than the $1.7 million deficit the company posted a year ago.
