They used new construction (prefab) in order to build as many as 30 houses a day. Designed for GI’s returning home from war this debut was such a success they contracted 4,000 more homes to be built only this time they would be for sale not for rent. New home owners were not required to put anything down and were given 30 year mortgages with the same monthly cost as renting.
Thus began Urban Flight and suburbanisation.
