Question about extending a lease agreement

[John Truong]

Hello,

I have a lease agreement that ends at the end of May. The lease automatically renews to month-to month starting June. The property is in Houston, TX, and I am using the form CJM 186253v.6.

I want to give my tenants the choice of renewing the 12-month contract at the same monthly rent or stay at month-to-month at $100 higher (or $50 higher with 6-month contract).

I am planning to send them a courtesy text about these options, and ask them how they want to proceed. 

Then what to do next? How do I make it official? What paperwork to sign? I found the Texas Association of Realtors Form 2005, but I cannot use it because I am not a realtor.

Thank you in advance for your help.
