Closing on Duplex with long term tenants

[Grant Francke]

Hello BP! I'm closing next week on a property that has 2 long term tenants (since March 2009). One of the tenants are older (65+). They treat and act like it's their house. Any tips on how to formally introduce my self to them? They are both on month to month and drastically under valued rents. This will be the first property we closed on with this long term of tenants In them. Thanks!
