Once again we need to bash the evil landlord and protect the innocent tenants. None of us know the situation the landlord is in. Maybe things got desperate. Maybe it won’t sell for months or more and there’s no need to spook the tenants. I would inform my tenants, but there’s no law requiring me to. If it’s a month to month lease, it can be broken by “either” party for any reason. So if the landlord changes plans and gives them 30 days to move out, he’s evil and if the tenant changes plans and moves out in 30 days he’s a hero? Business is business. Otherwise, let’s turn it all over to the heavenly state to manage it all for us and we can lives on Candycane lane. If anyone intentionally notified my tenants maliciously like you did, I’d sue them for interfering with my right to conduct business. You don’t know all the facts and pretending you do and acting on that makes you more self righteous than the evil landlord.
