'While the immigration rate stands at a record low, a reversal of this trend could significantly raise apartment demand, according to a press release on the report.'
This seems off - do they mean legal documented immigrants, because there are reports of 3000 undocumented people a day illegally coming into Texas via Mexico, some of whom are being bussed to other parts of America?
The concerns with 'building more apartment buildings' are resources in area - water, energy, transportation - and past disasters with places like Geneva Towers in South San Francisco which deteriorated into a crime ridden hell that had to be demolished in the '90's.
