Yes. Owners can sell a leased house. But, as others have pointed out, the lease remains in effect unless there is a provision allowing termination, as appears to be the case here. However, only a lawyer can advise you about exactly what is legal and about the specific "hidden" provision in your lease. As a general rule, I would suggest that the owner should have pointed out the 60-day termination notice when you signed the document. It would have been a simple courtesy. However, you also should have read the entire lease yourself. Unfortunately we are today presented with too many legal documents to sign, click on, or otherwise accept. We often fail to read even the most important ones. I've even talked to owners who did not know what was in their leases because they used a pre-printed form that they did not bother to read and understand.
