The redemption period is the time (5 weeks on a vacant property, 6 mo. on a inhabitited one) between the sheriff's sale and the date the property turns over to the winning bidder at the sheriff's sale. The winning bidder is usually, the bank or first mortgage holder. A property can, with some lenders, be sold short sale during the redemption period, if the mortgage holder ill allow it and work with the mortgagee.
I realize that's a tough answer to understand, but it's about as straight forward as I can make it. Short sale being the sale price of a property not being the full amount owed on the mortgage, and the mortgage holder or holders willing to accept less than owed and to forgive the balance of the debt.
In essence, there isn't a redemption period on a short sale.
I sure hope that helps.
