If you are living in a home in foreclosure, but your name is not on the mortgage how long do you have before they can evict you

After the foreclosure sale, you will receive an eviction notice which will mention the time period within which you will have to leave the property.

I agree with Adonis. The eviction notice will mention the time period within which you will have to leave to the property. The time period may vary from 3 days to 30 days as per the discretion of the new buyer and the lender.

thank you for your answer. I had read somewhere that in New York tenants are allowed to stay 90 days or longer if they have a signed lease
