The Man Who Turned Houses Into An Assembly Line

Levittown was the largest housing development in American history, but the house was the easy part. The engine underneath was the FHA mortgage, a government invention from 1934, and the same federal rulebook that built the suburban middle class also wrote redlining into the deeds. This is how the 30-year mortgage was designed, how it made millions of families rich, and how a color line was run straight down the middle of it. In 1948, on a former potato field on Long Island, crews moved down new streets doing one job each, a slab, a frame, a roof, and finished a house roughly every 16 minutes. More than 17,000 nearly identical houses went up. A young couple could buy one new for about $7,000, and a veteran could move in with almost nothing down and pay around $65 a month, less than renting an apartment. That house became the classic American middle-class fortune, often the family's entire inheritance. But before the 1930s a home loan ran 5-10 years with a big balloon payment and required about 50 percent down, and in the Depression roughly half of all mortgages defaulted. So in 1934 the federal government created the FHA, which insures loans that meet its rules, and its rules defined the 30-year, low-down-payment, fully amortizing mortgage we still use. The 1944 GI Bill added zero-down loans for 16 million veterans. And the FHA would pre-approve a builder's entire subdivision before construction, so William Levitt knew the financing for 17,000 houses was effectively guaranteed by the United States before he broke ground. The same rulebook had a color line in it. The FHA's underwriting manual told appraisers to weigh a neighborhood's racial composition, warned against inharmonious racial groups, and recommended racially restrictive deed covenants. Government maps outlined Black neighborhoods in red, where loans were nearly impossible to get. Levittown's deeds restricted occupancy to members of the Caucasian race. As late as 1960, Levittown, New York had about 82,000 residents and not one was Black. When a Black family bought a house in Levittown, Pennsylvania in 1957, crowds threw rocks and burned a cross for weeks. So the single greatest wealth-building event for the American middle class ran for two decades with a color line down the middle. White families got a government-guaranteed on-ramp to an appreciating asset; Black families, including veterans with the same GI Bill entitlement, were mostly shut out. Economists trace a large share of today's Black-white wealth gap to exactly this period and this mechanism. The Fair Housing Act of 1968 changed the rules, but by then the suburbs were built and the appreciation had already started compounding on one side of the line and not the other.
