Let's be honest here. It sounds as if you are looking for a legal reason to break your lease without having to pay the lease breaking fee so you can buy a house and attempting to justify a leaning/falling brick wall in the driveway as making the house "uninhabitable".
Reasons for breaking a lease in Texas:
When Breaking a Lease Is Justified in Texas
There are some important exceptions to the blanket rule that a tenant who breaks a lease owes the rent for the entire lease term. You may be able to legally move out before the lease term ends in the following situations.
You Are Starting Active Military Duty
If you enter active military service after signing a lease, you have a right to break the lease under federal law. (War and National Defense Servicemembers Civil Relief Act, 50 App. U.S.C.A. §§ 501 and following.) You must be part of the “uniformed services,” which includes the armed forces, commissioned corps of the national Oceanic and Atmospheric Administration (NOAA), commissioned corps of the Public Health Service, and the activated National Guard. You must give your landlord written notice of your intent to terminate your tenancy for military reasons. Once the notice is mailed or delivered, your tenancy will terminate 30 days after the date that rent is next due, even if that date is several months before your lease expires. State law may provide additional rules for early termination due to active military duty.
You Are a Victim (or the Parent of a Victim) of Sexual Assault or Stalking
State law (Tex. Prop. Code Ann. § 92.0161) provides early termination rights for tenants who are victims of sexual assault or stalking, provided that specified conditions are met (such as the tenant securing a protective order).
The Rental Unit Is Unsafe or Violates Texas Health or Safety Codes
If your landlord does not provide habitable housing under local and state housing codes, a court would probably conclude that you have been “constructively evicted;” this means that the landlord, by supplying unlivable housing, has for all practical purposes “evicted” you, so you have no further responsibility for the rent. Texas law (Tex. Prop Code Ann. §§ 92.056, 92.0561) sets specific requirements for the procedures you must follow before moving out because of a major repair problem. The problem must be truly serious, such as the lack of heat or other essential service.
Your Landlord Harasses You or Violates Your Privacy Rights
Texas does not have a state law that specifies the amount of notice your landlord must give you to enter rental property. If your landlord repeatedly violates your rights to privacy, or does things like removing windows or doors, turning off your utilities, or changing the locks, you would be considered “constructively evicted,” as described above; this would usually justify you breaking the lease without further rent obligation.
