The Nation's Housing: Lenders should give energy savers a break

WASHINGTON — If you buy or own an energy efficient house, does this make you less likely to default on your mortgage? Is there a connection between the monthly savings on utility costs and the probability that you'll pay your loan on time? A new study by the University of North Carolina suggests that the answer to both questions is a resounding yes.

Using a sample of 71,000 home loans from across the country that were originated between 2002 and 2012, researchers found that mortgages on homes with Energy Star certifications were on average 32 percent less likely to default compared with loans on homes with no energy efficiency improvements. Energy Star homes — renovated or new — provide documentable savings of 15 percent or higher on utility bills compared with houses containing minimal energy improvements.

Researchers separated out factors other than energy efficiency savings that might account for the strikingly different performances by borrowers on their mortgages. They controlled for house size; age of the house; neighborhood income levels; house values relative to the area median; local unemployment rates; borrowers' credit scores; loan-to-value ratios; electricity costs; and even local weather conditions.

The sample came from a mortgage data repository managed by CoreLogic, a California-based company that has access to millions of loan files and payment records supplied by major banks, lenders and servicers. The average sale price of both the energy-efficient homes and the others was approximately $220,000.

So why the big difference in payment performance? To Cliff Majersik, executive director of the Institute for Market Transformation, a Washington, D.C., think tank that sponsored the research, there's no question.

"It stands to reason," he says, "that energy-efficient homes should have a lower default rate because the owners of these homes save money on their utility bills, and they can put that money toward their mortgage payments."

In light of the superior performance of mortgages on certified energy-saving houses, what discounts or preferences can borrowers or owners of such houses expect at the bank when they go in for a loan? After all, a key component of the interest rate you pay on a mortgage is compensation for default risk and produce big losses for the lender or bond investor.

For example, if you have a low FICO credit score of 620, you present a high risk of nonpayment to the lender and are virtually guaranteed to be charged a higher rate. On the other hand, if you have a platinum 800-plus FICO score, you're likely to be quoted the best rates and generous underwriting terms — all because your statistical risk to the lender is lower.

But here's the problem with the way the mortgage system treats energy efficiency: You'd be hard pressed to find any lenders who'll give you a better rate quote on your application, even if you showed them your Energy Star or HERS certifications along with documentation that your house saves money on utility bills.

The authors and sponsors of the study think lenders should start factoring energy efficiency into their underwriting. They've also begun meeting with officials from the mortgage industry, Congress and government to suggest how to do it: If not a lower interest rate, they argue, then at least give loan applicants who can demonstrate significant energy bill savings a break on upfront fees, debt-to-income ratios, or maybe some wiggle room on minimum down payments. It just makes sense.
