As the housing market enters its busiest season, economists and industry analysts foresee a spring sales boost due to high affordability conditions, low interest rates, and improvements to the overall economy. David Berson of the PMI Group told The Wall Street Journal that improvements in the job market should make consumers more comfortable buying a home, as they have more confidence in their income-earning potential. And though February sales data was weak, The National Association of Realtors said the weakness may have been driven by bad winter weather and deals canceled over low appraisals. Lawrence Yun, NAR’s chief economist, said sellers are becoming much more realistic in terms of valuing their homes, which should lead to more favorable buying conditions this spring.
