I sold my share to a partner a few months ago (for a small but very high-percentage profit).
My deed was lost in the mail. I was instructed to visit the Register of Deeds for a copy of official records, but you might want to call and ask if you need to do the same: http://www.waynecounty.com/deeds/index.htm. That being said, @Quinton Myers I don't think you need a copy of the deed unless you really want one - just call and ask if it's officially under your name.
@Michelle Petropoulos, very late reply, but if I recall correctly, homeowners were allowed to redeem their houses and adjacent vacant lots up until the week preceding the auction in 2015. Consider: why would the city turn away the original owner's money?
On the whole, the podcast is harsh on Detroit and for good reason, but I cannot think of a better training ground if you are resourceful, patient, cautious and looking for a very cheap education. I replicated the exact same process I did in Detroit in New York City and am set to close on a foreclosure next week.
Plus, Detroiters are surprisingly kind, fiercely protective and they love to talk about their neighborhood - even to some non-Detroit Asian guy who knocks on their door and asks if he can take pictures of their home as it's about to go into foreclosure! Haha.
