Apartment-building investors were also expected to feel pressure to sell as Lehman unloaded its debt and equity pieces of the $22 billion purchase of Archstone, the third-largest United States real estate investment trust (REIT). Archstone's core business was the ownership and management of residential apartment buildings in major metropolitan areas of the United States. Jeffrey Spector, a real-estate analyst at UBS said that in markets with apartment buildings that compete with Archstone, "there is no question that if you need to sell assets, you will try to get ahead" of the Lehman selloff, adding "Every day that goes by there will be more pressure on pricing."[33]
