Unfortunately renters don't have much protection from their landlords if the their landlords choose to sell or evict them without cause. The "Without Cause" refers to evictions where the landlord says that they are going to either renovate the unit ("renoviction"), or so that the landlord or a member of their family can move in. In both cases, the tenant can't stay, but you might be able to squeeze a few months of rent out of your landlord (which won't help you find a new place with an affordable rent, as rents are up everywhere – you'll end up paying more per month for sure).
If you do receive an eviction notice for either of these purposes then you should definitely ask for advice, here or from the FMTA Tenant Hotline, and also probably from a lawyer.
