According to a recent Wall Street Journal article rents and occupancy in apartment buildings in the U.S. is continuing to rise steadily. WSJ cites a report done by Reis Inc, a company that collects data on real estate, which found that only 5.6% of the country’s apartments were vacant at the end of Q3 2011, down from 5.9% at the end of the first half of the year. That’s the lowest level since 2006. To top it off the only market in which rents declined in the entire country was Las Vegas, NV.
