Economists said Trump seems focused on lowering mortgage rates, not housing prices. When President Donald Trump has talked about his recent proposals to make housing more affordable, he's focused on one particular cost: mortgage rates. It’s part of an effort to make homeownership more affordable without driving down housing values. However, he said that lower interest rates were “good for everybody.”“This suggests that the administration sees lower mortgage rates as the preferred channel through which to improve affordability,” wrote Wells Fargo economists Charlie Dougherty and Ali Hajibeigi. But lower mortgage rates would probably boost demand.
