Mortgage rates posted another week of mixed results as weak job growth helped keep a lid on inflation, Freddie Mac and Bankrate.com reported today in their weekly surveys.

According to Freddie Mac, the 30-year fixed-rate mortgage dipped to an average 6.15 percent from last week’s 6.16 percent and the 15-year fixed-rate mortgage held at 5.87 percent. Points, which are fees lenders charge for loan processing expressed as a percent of the loan, averaged 0.5 on the 30- and 15-year loans.

A 28-year-old house flipper from Kansas City, Mo., has been sentenced to five years in prison without parole and ordered to pay $4.9 million in restitution after pleading guilty to mortgage fraud conspiracy and money laundering.

Prosecutors said Jeffrey Tyler Wine admitted to conspiring to defraud mortgage lenders by convincing them to loan investors $17.6 million to purchase 280 residential properties from November 2001 to May 2005.

Wine purchased, rehabilitated, managed and sold residential properties in the area, acquiring them at reduced rates at foreclosure, tax and bankruptcy sales. After the properties were renovated, they were advertised as investment properties available for no money down, prosecutors said.
