WASHINGTON (AP) — President Donald Trump says he is directing the federal government to buy $200 billion in mortgage bonds, a move he said would help reduce mortgage rates at a time when Americans are worried about home prices. Trump and the White House have been trying to show they are responding to voter concerns about affordability ahead of midterm elections in November. Home prices have generally risen faster than incomes because of a construction shortage, making it harder for renters to buy their first home and for existing owners to upgrade. Trump says the two mortgage companies under government conservatorship, Fannie Mae and Freddie Mac, have $200 billion in cash that will be used to make the purchase.
