Ann Arbor bank creates subsidiary for Muslims: "Among the laws of Shariah is a ban against paying or receiving interest.

University Bank also offers a mortgage alternative loan transaction program - or MALT - which replaces a traditional home loan with a redeemable lease.

The bank holds the home in trust, and a home buyer makes monthly payments to that trust. Each rent payment includes a set amount of savings, which builds the buyer's equity in the home. When the savings account equals the home's original purchase price, the buyer owns it."
