It will take time for Amazon employees to buy the housing and increase prices, yes, but there are professional overseas investors doing true investing, betting on appreciation from things like, oh, 25,000 software programmers moving to a city, that will work through their network of brokers and pull the trigger on hundreds of houses as soon as the news is announced.
