Federal moratorium - can 30 day notice still be issued?

[Sara W.]

I have a tenant that is tenant at will and according to my lease agreement I only need to give them a 30-day notice if I no longer want to continue their month to month lease. Under the federal moratorium can I still issue them a 30 day notice or do I need to wait until the federal moratorium expired in June 30 before I can do serve them any notice? The property is located in MA and I don't think there's any state moratorium in effect right now. I don't think the tenants want to move, but we do want to sell the property soon and most of the interested buyers need the property to be delivered vacant. Thank you for your helps in advance!
