Tenant not responding about Lease renewal

[Bishara M.]

Dear my wonderful BP Family,

My wife and I are Househacking in Carrollton, TX a 4x2 single family home. Renting by the room. The situation is as following, the Tenant's lease ends on Oct 31st 2021.

I sent out a Lease renewal asking if they would like to renew, 38 days before the lease ends, it's been over 2 weeks and they only "verbally" said yes they want to renew, but havent responded to any of my texts for the past 2 weeks. ( I only sent 3 texts).

I provided a deadline for make up their decision (Oct 8th) in that text, That was sent Sept 24th.

Today, Oct 8th, I texted for AN URGENT reminder, put a note under the door reminding them that today is the last day to "decide". No response or anything yet, I've been kept in the dark.

What should I do in my case? I reviewed the contract and unfortunately I didnt find any clause that states a deadline for their renewal decision or that it will convert month to month after, is it by default? 

How should I go about this? I'm really anxious at this point. 

Thank y'all in advance!!
