Mortgage Foreclosure to Eviction Timeline, Detroit-- Anyone Know?

[getmoore]

Asking this for acquaintances with no net access. They're living in/renting a Detroit house owned by a relative. Paying cash, no lease. Owner told them to find another place, that she was selling the house. We found it online listed as a short sale, but realtor listing has been removed.

Now zillow.com shows this notice about the house--
This property was scheduled to be sold at a foreclosure auction on 10/30/14 at 11 a.m. at THE CIRCUIT COURT WITHIN WAYNE COUNTY, DETROIT. Because auction dates often change or are postponed, it is unknown at this time if this auction was held. Please confirm with a foreclosure specialist.

What does that mean, or probably mean? How can they find out? Owner has been unhelpful, other than to say she has the house for sale [[which we figured would take forever plus, to get a short sale approved), though apparently the mortgagor has foreclosed.

Wayne County shows no back taxes due on the property-- presumably the mortgage co. continued to pay them.

What happens next? How long do they likely have to vacate-- before sheriff shows up to haul all their belongings out to the street, if that's the next step.

They have continued to pay rent to her, but I'm thinking at this point that is a big So What ...

If the house was sold at auction I believe there is a six month redemption period from the date of sale. So I think they should have at least six months.

I know that is so for TAX foreclosures, but is it true for private mortgage co. foreclosures as well?
