Google announced they are testing in California Google Compare for US mortgages. You can access it over here but again, it seems to only work in California.
"Google Compare for mortgages provides a seamless, intuitive experience that connects lenders with borrowers online," Google said. You will be able to find purchase and refi rates, along with a real-time, apples-to-apples comparison of rate quotes from other lenders. Google added that "borrowers can also see ratings and read helpful reviews, and enter relevant information - like loan amount, estimated credit score, or home value - to receive rate quotes that match their needs."
Google Compare keeps expanding, from loans, credit cards, mortgages and so on.
Participation in Google Compare is based on a flexible cost-per-lead (CPL) model.
