THE FUTURE &
OPPORTUNITY

For the next several years, 601W will seek to take advantage of the enormous opportunities associated with a prosperous real estate market, using its considerable experience and acumen to acquire properties at well below their fair value. The company plans to target assets similar to those it currently owns through outright acquisitions, the purchase of distressed debt, and participation in other unique opportunities that may arise. In the past, 601W has been able to meet its equity capital needs from a roster of high-net-worth individuals. Recently, in several very large transactions, 601W has also partnered with institutional equity investors. The company continues to enjoy exceptional relationships with its institutional partners and lenders. 601W believes that the capital requirements in the future will be much greater than in the past, and is looking to form strategic alliances with additional sources of capital for both debt and equity.
