Zillow, a Seattle-based mobile and online real estate information company, launched its Zillow Mortgage Marketplace iPhone app Tuesday for a mobile loan shopping experience.

The app combines personalized loan quotes with calculators and tools to help borrowers ascertain home affordability, monthly payment amounts, and whether refinancing makes financial sense.

Home shoppers can also use the app to receive instant, personalized loan quotes from lenders. Borrowers fill out

loan requests by providing information about the home and their own financial situations.

Users receive an average of 25 loan quotes per request and can compare rates and lenders side by side, including scanning more than 8,900 consumer-submitted lender reviews. The borrower can then connect with lenders and begin the process of securing a home loan via the app.

“This addition to Zillow’s already robust suite of real estate mobile apps gives consumers valuable personalized mortgage information when they most need it – out shopping for homes,” said Spencer Rascoff, Zillow’s CEO.

“Our commitment to providing people with the best tools and data for real estate is especially important on location, and now there’s a Zillow app for every stage of the home-buying process,” Rascoff added.

The Zillow Mortgage Marketplace iPhone App is now available for download.

Zillow, Inc. operates Zillow.com, Zillow Mortgage Marketplace, and Zillow Mobile. The company reported 22 million unique users of its Web site and mobile applications during May 2011.
