President Donald Trump’s plans for bringing homeownership within reach of more Americans involve pushing for lower interest rates on home loans and credit cards, and banning large institutional investors from buying single-family homes. Trump outlined four housing policies his administration is pursuing during his address Wednesday at the World Economic Forum in Davos, Switzerland. Each had been previously mentioned by him or his administration in recent weeks, part of a broader push to address affordability generally, a hot-button issue with voters heading into the midterms.
