JPI may have the keys to your next place. As one of the largest luxury apartment developers in the US, JPI has developed or managed more than 200 apartment, condo, and student housing complexes. The company typically buys underperforming properties in desirable areas and upgrades them with such features as parking garages, fitness centers, and 24-hour concierge services. JPI's more than 50 student complexes (many of which have "Jefferson" in their name) include game rooms and fitness centers. Founded in 1976 as Jefferson Properties, Inc., JPI was a subsidiary of Southland Financial until the early 1990s when Hunt Realty became a major investor.
