You're mistaking housing costs with prices. Housing costs are the input prices of components that entrepreneurs accept or reject to produce housing.
Such as: * price materials producers demand for their products (concrete, wood, electrical wire etc) * the labor prices, labor sellers demand (Carpenters, iron workers, etc) * the prices land owners demand to either keep land undeveloped or developed * the prices state agents demand to abstain from interfering with home building.
Consumption can't drive up a producer's input costs. Consumers may abstain from purchasing from a producer unless the producer meets different inputs ("I demand you only buy the labor of architects who live near me and not people far away").
