The podcast challenges the notion that an aging population, often referred to as the "silver tsunami," will alleviate the housing affordability crisis by boosting housing supply. Research indicates that many empty-nesters live in areas that are already affordable, and a significant number are hesitant to sell their homes due to low mortgage rates or having no mortgage at all. Moreover, those who do sell tend to move to pricier coastal regions, making the situation worse. The real solution lies in constructing more densely populated housing, particularly in sought-after coastal cities, while also tackling local regulations that impede development.
