Comparison Shopping Savings in Mortgage Market

Alexei Alexandrov and Sergei Koulayev of the Consumer Financial Protection Bureau have posted a working paper, No Shopping in the U.S. Mortgage Market: Direct and Strategic Effects of Providing Information to SSRN. The paper is the first to answer the question, “How much do consumers lose by not shopping enough for mortgages?” (5) They find that “for the average consumer, the the difference between the actual and the lowest offered rate amounted to an extra $300 per year.” (Id.)

The abstract reads,

We document and analyze price dispersion in the U.S. mortgage market. We find significant price dispersion in posted prices in the retail channel: for example, a consumer with a prime credit score and with a 20% down payment might see a spread in interest rates of 50 basis points, controlling for all relevant consumer/property characteristics, including discount points. We also show, from survey evidence, that close to half of consumers did not shop before taking out a mortgage, and worse, many consumers do not seem to realize that there is price dispersion. Using a proprietary dataset of lenders’ ratesheets, we estimate an equilibrium model of costly search where a share of consumers holds incorrect beliefs regarding price dispersion. Whereas high search costs is one reason behind the lack of search, we show that non-price preferences also play an important role in preventing consumers from searching more; and so an effective policy would target both. In one of our counterfactuals, we show that eliminating non-price preferences results in savings of about $9 billion dollars a year.

In addition to its significant finding on a new topic (one that should have policy implications for the Consumer Financial Protection Bureau), the paper also demonstrates the value of government research on the mortgage markets.

The paper relies on data from the National Survey of Mortgage Originations. The NSMO is a survey designed by the CFPB and the Federal Housing Finance Agency.  It is sent out on a quarterly basis to a nationally representative sample of recent mortgage borrowers. Jeb Hensarling (R-TX), the Chair of the House Financial Services Committee, has introduced legislation to stop the CFPB from conducting research on the mortgage markets. That would be a bad result for consumers.

Good Data Makes Good Mortgages

The CFPB issued a proposed rule about increasing the quality of information that lenders report about mortgage applications. The press release regarding the proposed rule states that these changes will ease the reporting burden on lenders, and that may very well be true. But the contested part of these rules relate to the type of information to be collected:

  • Improving market information: In the Dodd-Frank Act, Congress directed the Bureau to update HMDA regulations by having lenders report specific new information that could help identify potential discriminatory lending practices and other issues in the marketplace. This new information includes, for example: the property value; term of the loan; total points and fees; the duration of any teaser or introductory interest rates; and the applicant’s or borrower’s age and credit score.
  • Monitoring access to credit: The Bureau is proposing that financial institutions provide more information about underwriting and pricing, such as an applicant’s debt-to-income ratio, the interest rate of the loan, and the total discount points charged for the loan. This information would help regulators determine how the Ability-to-Repay rule is impacting the market, and would also help the Bureau monitor developments in specific markets such as multi-family housing, affordable housing, and manufactured housing. The proposed rule would also require that covered lenders report, with some exceptions, all loans related to dwellings, including reverse mortgages and open-end lines of credit.

Lenders are not going to like this, because this new information may be used against them in a variety of ways — in Fair Housing lawsuits, by the CFPB in enforcement actions, by members of Congress seeking to increase credit access to various constituencies.

I like this because regulators and academic researchers have been hamstrung by limited and stale data on the fast-moving mortgage market. The mortgage market is often driven by the short-term profit-seeking of private actors and by special interests pushing their agendas with the Executive and Legislative Branches.  Good data can inform good decision-making that can ensure that the housing finance system is vibrant and provides sustainable credit for households over the long term.

Comments on the proposed rule are due by October 22, 2014.
