Sheriff Sale? - This is the actual date of foreclosure. This is the same date that you were notified of through the mail and the date that was posted on the home. You do not have to move out on this date.
Now What? – Your home has been officially foreclosed on and, will now show up in your credit report as such. At this point your home has either been bought or current mortgage company is retaining it. This is the start of the Redemption Period.
Redemption Period? - This can be as short as 30 days or as long as one year. The notice that was placed on your door states this time frame. It usually is a six month period. The only way to keep your home at this point is to re-purchase it before the end of the Redemption Period.
