The potential developers would seem to fall into a few categories, according to James L. Elcock, executive vice president at Meredith & Grew. "These properties typically get interest from three types of parties, other churches, institutions and residential. Developers are not going to be looking for class A office or industrial conversions."Institutions such as charter schools, arts groups and museums may find the properties particularly appealing, Elcock says. "Institutional users like the properties for their bone structure, parking, architectural layouts and location. It would cost a lot to build projects like these from scratch, and a lot of these institutional groups don't have large budgets. It could be a win/win situation."Proposals, which will be solicited over the next 90 days, will be reviewed by the Archdiocesan Real Estate Office and the Real Estate Advisory committee, which will make their recommendations to chancellor David W. Smith. He will review the financial terms and the social considerations connected with the offers and forward his recommendations to Archbishop Sean O'Malley. If the Archbishop is inclined to accept the offers, permissions will be sought from the College of Consultors, the Finance Council, and where needed, from the Holy See before proceeding with the actual sales.
