It's true - as agents, we are not allowed to provide information about crime. And when you think about it - crime is not our job - helping people buy or sell real estate is our job.
As suggested previously in this thread - a call to the Minneapolis Police Dept (probably the 4th precinct) might be a good place to start. I've also seen buyers network among their Facebook friends to find resources for additional information, and of course, searching on the Internet.
As a side note - there are a number of nicely renovated homes done by local nonprofit developers in Minneapolis and some first ring suburbs in an effort to provide more affordable homes. These homes do have income restrictions, but these income restrictions are often much higher than most buyers realize, and there are often large amounts ($10,000+) down payment assistance programs available specifically for the purchase of these homes.
I've worked with a number of buyers who purchased a home using these programs, and I have loan officers who specialize in knowing how to utilize down payment assistance programs to the maximum benefit of the buyer. Since helping people buy and sell real estate is my job - knowing about these opportunities is a focus of my business.
