Getting a detailed look at the cost of insurance in different parts of the United States has been almost impossible until now because private insurers don’t publicly disclose what they charge. But two researchers, Benjamin Keys, a professor of real estate at the University of Pennsylvania’s Wharton School, and Philip Mulder, a professor at the University of Wisconsin School of Business, found a workaround.
Homeowners often pay their insurance premiums together with their mortgage and property tax, through an escrow account. They make a single payment every month to a mortgage service company, which then pays the mortgage lender, the local government and the insurance company. The system is designed to ensure homeowners never miss a payment.
Working with CoreLogic, a property information and analytics company that collects data from mortgage servicers, the researchers obtained data for about 12.4 million of the nation’s roughly 80 million owner-occupied households. That data showed how much those households paid in escrow annually from 2014 through 2023. After deducting payments for mortgages, property tax and other fees, they could estimate what each household paid for property insurance.
