After foreclosure is sold how long to vacate home?

The time varies depending on the purchaser. Once they purchase they can start eviction proceedings. If you refuse to vacate at every step along the way, the process will probably take about 30 days. You can always attempt to work out a period of time to remove your things with them.

It depends on when the purchaser decides to evict you. But typically, the longest time one can stay before eviction is a month. I would ask the purchaser if possible. They should present you eviction papers.
