New Zealand (similar population and size to Oregon) has an immigrant population[1] of ~1/3 and we are a poorer nation BUT houses are available here - despite our population growth significantly exceeding the USA.
If houses are not available in say Oregon, it isn't due to "population explosion" there. And it isn't due to lack of land or population density (NZ is similar to Oregon for both).
