Previously, a former owner residing in real property after a mortgage foreclosure was considered a 'tenant at sufferance' and not entitled to any notice before instituting legal process to evict. Sensible foreclosing lenders usually give the foreclosed owner notice to quit and a reasonable time to vacate, if not some form of 'cash for keys' whereby the lender in effect compensates the former owner to leave voluntarily. Based on a Lawyer's Weekly summary it appears a Massachusetts Southeastern Housing Court judge has indicated lenders are required to give 90 days notice to quit.
I have not been able to obtain a copy of the decision yet but if the summary is correct postforeclosure evictions in Massachusetts have changed drastically. More later.
