Instead, it took depressed real estate prices as an opportunity to build out properties at lower prices.

In many ways, REITs are more like income investment vehicles than a play on the real estate market. Because commercial REITs such as BXP rent properties through long-term "triple-net" leases, they're able to collect reliable surprise-free revenues as long as tenants don't go bust.
