Good Question

Would you move into a house where a killing- suicide or murder in the house happened in the past?
From the Detroit Free Press: Kayla Bentley was thrilled to move into her in-laws’ house as a 19-year-old newlywed back in 2010.
That is until she found out that the unassuming house on a quiet street in Allen Park was where Justin Olszowy, a mentally unstable 26-year-old man, fatally shot his parents two years earlier.
“We were kind of upset about it,” she recalled. “It freaks me out, especially because in this situation, he’s not dead. If he was released or escaped, this is where he’d come.”...
Properties that were the sites of homicides or suicides have an interesting stain that remains long after crime-scene investigators leave. For some potential buyers, owning a home with notoriety gives them, well, notoriety. Others are freaked out by it.
In short: I see dead people — and lovely crown moldings.
“One group says, ‘I don’t want to have anything to do it.’ Another group says, ‘I’ll get the carpets cleaned. How much can I buy it for?’ ” explained Jason Abrams, owner of the Abrams Team based out of Keller Williams in West Bloomfield and star of HGTV’s “Scoring the Deal.”...
Under Michigan law, real estate agents aren’t obligated to disclose whether the property was or was suspected to have been the site of a homicide, suicide or illegal activity “which had no material effect on the condition of the real property or improvements located on the real property.”....
However, elsewhere in the country, some states, such as California, require would-be buyers to be told. (In the Golden State, that’s spawned a micro-industry of home cleansers who remove spirits from homes.)   http://www.freep.com/article/20130528/NEWS05/305280012/Homes-for-sale-where-murders-occurred
