Does a New Landlord need to inform Tenants of change in ownership

[Toks Akindele]

Currently in the process of closing on a package of SF homes and I wanted to ask whether a new Landlord needs to write a letter directly to the tenants or whether it is better to let the Property Manager inform them. If you think the new landlord needs to introduce themselves, can you help provide some important items to mention in this initial communication. If you also think the new landlord doesn't need to introduce themselves but stay status quo through PM, then state why. Thanks for your attention
