More than half of the people who have their home paid off are retirement age. That doesn't reflect the current market conditions. If you as a baby boomer bought a home your mortgage was never even close to what a millennials' mortgage was because when you were a young adult homes were still affordable on an average wage. Instead of the average house costing $421K it was $60K or even less. Even with inflation you had the luxury or refinancing through the years on a modest price.
While 8% mortgage rates mean potential buyers are squeezed, the last decade saw a surge in people who own their homes outright.
