From Triple Locked to a parallel housing economy.A new era of critical-mass housing.

For ninety years the Triple Lock — redlined in 1936, stamped "distressed" today, then priced out by the mortgage algorithm — taught capital to avoid ~15,000 census tracts and 24 million families. The answer was always incremental: one home, one pilot, one ribbon-cutting at a time — never enough to move a market. But markets tip at critical mass: 20% of a city's cost-burdened families — a floor of five thousand homes. Below that line, building is a subsidy; above it, a self-sustaining economy. City after city, that compounds into a parallel housing economy a million homes strong. Not high-risk. Mispriced.
