In Texas, a renter rents a house with a one year lease term.
Renter is not late on rent and is currently paying rent on time.
Renter lived in the house for 7 months and moves out, but continues to pay rent in accordance with the rental agreement.
Renter did NOT formally terminate the lease, but did tell landlord that they have moved out, but will continue paying until the lease term expires. Landlord rents out the house to another renter (presumably in order to get double rent money)
1) Renter re-move into the property? or barring that, can renter, 2) Refuse to pay any more rent?
It seems that landlord has breached the lease agreement by re-taking possession of the property and renting the house making it so that renter cannot move back in or live there if they wanted.
