The building that we live in is in contract for sale. The LL has sent us a notice saying that our tenancy will end on July 31. We are definitely not rent stabilized and we have no lease. As far as I know the other six tenants are in the same situation. The LL told us five months ago that the property is going up for sale and at contract all tenants would be given a notice to vacate, so we have been expecting this.
My question is about the form of delivery of the Notice. She sent it by email. Is that legal? If not, how should I expect it to be delivered legally?
