Inherited Tenants Late On First Months Rent

[Mark Anderson]

I currently just purchased my first quadplex and inherited 4 tenants. This is my first month collecting rent and they are all on month to month leases. I have not met the tenants as they were not there when i posted on their doors with my contact information and how rent will be collected digitally through paypal or venmo. The seller let them know that i was going to be the new owner as well. In the state of Texas they are late 1 day after when rent is due the first. However their existing lease says they are not late until the 5th which i have decided to honor.  I am trying to train my tenants the right way and was wondering how i should go about this. Post a notice to vacate notice on the 5th at their door? Or begin to take proper steps now

Any advice on how to proceed with this?
