“Decades have passed since activists have been so successful in forcing a change of control that would otherwise not have transpired,” Green Street said, citing the sudden change up in Equity Commonwealth (NYSE: EQC).

Moreover, value investors may also find some cheaper plays in the mortgage REITs space. For instance, the iShares Mortgage Real Estate Capped ETF (NYSEArca: REM) and the Market Vectors Mortgage REIT Income ETF (NYSEArca: MORT) both show a 9.1 price-to-earnings ratio and a 1.0 price-to-book.
