The drop in oil prices will boost housing: Oil prices have plunged 45 percent since June, which could inadvertently provide a lift to the housing market. Households in the U.S. spend more than $1,800 on energy-related costs annually, and 22 percent of that energy consumption is due to residential real estate. So while the drop in oil prices typically has been linked to a reduction in driving-related expenses, it clearly also reduced energy-related expenses for residential real estate.
