Closed first deal--inherited tenants questions

[Christina Linscott]

Hello all, 

I just closed my first deal on a duplex that I plan to owner occupy. I have a tenant who's lease is up on 30 November, and at that time we plan to move into that side of the home. The state of Texas only requires 30 days notice to vacate, but these tenants have been in the unit since 2002, so I feel like I should give them extra notice since they are probably not prepared to move. Anyway, what are your takes on this? Should I give 60-90 days notice to them so that they can prepare for a move or am I being too nice? From all of the rental history I have gotten from the previous property manager they have been good tenants. 

Also, the seller didn't give us the keys to the units. My husband spoke with them and they told him that we have to get the copies from the tenants....that just doesn't sound right to me at all. I'm thinking we should just set a time up with the tenants to change the locks and give them new keys to be on the safe side. Any advice on this?
