News Corp says it will pay USD 21 per share in cash for each outstanding share of Move. That represents a 37 per cent premium over the stock's closing stock price of USD 15.29 yesterday.
Move operates the website realtor.com and News Corp says it displays more than 98 per cent of all for-sale properties listed in the United States.
The media company says Move's network of websites reaches about 35 million people per month.
New York-based News Corp, which is controlled by Rupert Murdoch, expects the deal to close at the end of the year.
Move's board has unanimously approved the acquisition.
