Not renewing a list as I want to sell my property

[Jane L.]

I am thinking about not renewing my lease (which is expiring in a week) as I want to sell a house.

The property is in CA. Is it good just tell the tenants about not renewing and ask them to move out. 

I know the requirement for the notice is 60 days. I don't have problem with that. In fact, I am planning to give them 6 months notice in advance, in good faith, and also give them plenty of time to find their new place.

My questions are :

(1) simply informing the tenants about not renewing in a form of letter

is GOOD?

(2) I heard that now asking tenant to move out, landlord has to proved one month's free rent? 

Does it apply to my case - which is NOT eviction, just NOT renewing the lease ?

Thanks for your insights and replies.
