Opening context:
For the last half-century, America's population growth has been concentrated in the sweltering, equal parts bone-dry and waterlogged, yet ever-sprawling Sunbelt... But that abundance is already becoming a thing of the past. Across Sunbelt metros like Phoenix, Dallas, and Atlanta, housing supply growth has actually plummeted since the early 2000s.

"America's suburban frontier," the authors warn, "appears to be closing." The findings suggest that the fundamentals of housing in Raleigh, Orlando, or Miami are not so different from every other hot real estate market in the country.

She stresses that communities shouldn't be afraid of going too far in repealing zoning rules, and that if anything, they should err on the side of going further.

Conclusion:
