Report details ways homes are used to launder money

Money laundering harder to spot than mortgage fraud

About one in five suspicious activity reports banks file with federal regulators over concerns about a residential real estate transaction show signs of money laundering or tax evasion, according to a new Treasury Department report.

The report found evidence of money laundering or "structuring" — transactions involving incomplete or falsified records — in 20 percent of suspicious activity reports involving residential real estate transactions between 1996 and 2006.
