Executors right regarding properties

My wife and her brother are co-executor of their mother's estate. My wife's brother has power of attorney. My wife and i were living with and taking care of her for the last four years before her death. Since he death we have trying to find somewhere else to love but economics and the pandemic have made it very hard. He has now said he wants us out by the end of the month so he can sell the condo. We want to move, do not want to further escalate an already acrimonious situation, but we are having issues finding housing. Can we be evicted? Forced out?
