Tenant is late on rent

[William C.]

I have a tenant whose rent is due on the 1st with a grace period through the 3rd.  I contact him on the 5th and was told he is in the hospital and he would pay the rent plus the late fees.  I still have not received the rent as of today.  It sounds like this is just an excuse.

This is the first time I met this problem so I would really appreciate any help on how to deal with it.  Should I serve him a 3 day pay or quit notice?  Does it have to be written or email is fine?  When should I start the eviction process?  I am in Texas BTW.

Thanks so much for your help!
