For a landlord, especially one with multiple properties, it may be expected as a normal part of business.Although it may be "legal on paper", I believe it would be very challenging for a landlord to successfully win an unlawful detainer action with absolutely no prior notice of non-renewal of a tenant with a lease for at least one year.

I would personally refrain from even contemplating any creative ways to get someone out and instead, just refer it to an eviction attorney for an unlawful detainer.

After a specified time if your tenant does not stop subletting or does not vacate, your attorney will file an unlawful detainer to remove the occupants.

It's going to cost you roughly $1K to do an unlawful detainer lawsuit and you might have to give 60 days notice.

Otherwise, I'll have to sue for unlawful detainer & have the sheriff remove her. 

My state requires a 3-day grace period before I can charge late fees or start eviction.Rent is due on the first day of the month.If not received by the fifth day of the month, then I charge a late fee.If they haven't paid everything in full by the 10th day of the month, then I hit them with a 3-day Pay or Quit.If they don't pay everything by the end of the third day (or move out), then I file in court for a forcible entry and detainer.

It will list the unlawful detainer, I use this information to gauge how good a property management company is at placing good tenants. 

That should cover most of what you need to know.The relevant sections of the law (in Texas) are: Texas Property Code•Chapter 24 (Forcible Entry & Detainer)•Chapter 54 (LL's Lien)•Chapter 91 (General Provisions)•Chapter 92 (Residential Tenancies)•Chapter 93 (Commercial Tenancies)•Chapter 94 (Manufactured Homes)•Chapter 301 (Fair Housing)Texas Rules of Civil Procedure•Rules 509 – 510Most will *not* apply to every case, so don't get intimidated.

immediately post the property for unlawful detainer and start the  paperwork.

Once the 3 days have passed and rent has not been paid, then an unlawful detainer claim is filed in court.
