moneyscience.org : Islamic mortgage market to expand
"The Islamic mortgage market is set to grow by 47% a year and could be worth £1.4bn by 2009, market research group Datamonitor has said. There is a growing demand from the UK's 1.8 million Muslims for mortgages that comply with Sharia law. The law forbids interest payments;"
While Islamic banking is growing rapidly in the UK, there does not appear to be much supply of Islmanic Banking in the US. Watch for it to start.
