America's housing affordability crisis shows no signs of abating as mortgage rates remain stubbornly elevated, pricing millions of would-be buyers out of the market and trapping existing homeowners in place. The average 30-year fixed mortgage rate stood at 6.87 percent this week, according to Freddie Mac.

The lock-in effect β€” where homeowners with sub-3 percent mortgages from the pandemic era are reluctant to sell and take on higher rates β€” has severely constrained inventory in most markets. New listings remain some 20 percent below pre-pandemic norms even as construction activity has gradually recovered.

The consequences for younger Americans are particularly stark. The homeownership rate for adults under 35 has fallen to its lowest level since the Census Bureau began tracking the metric, with many millennials and Gen Z adults remaining renters far longer than prior generations.

Policy proposals to address the crisis range from incentivizing local zoning reform to expanding federal mortgage assistance programs.
