After the foreclosure sale, you have no legal right to remain in the property. The amount of time you can remain as an illegal trespasser before the sheriff physically throws you off the property depends on how quickly the legal owner applies for a writ of possession.

After the sale, the sale has to be confirmed and a certificate of title issue to the purchaser. That process cannot occur in less than 10 days, often takes longer. It is even possible that the sale would to be confirmed at all.

The writ of possession can be obtained as early as a handful of days after the certificate of title is issued. The Hagen Law Firm always advises the borrower to be out NO LATER THAN the date that the certificate of title is issued and preferably earlier, by the date of the foreclosure sale. To be removed by the sheriff via a writ of possession is an experience to be avoided.
That is up to the owner of the property. You are behind the eight ball at this point. If you want to stay in the property, you need to file for a set aside of the foreclosure sale. We would be able to advise you on how to do this.
