[Landlord US-TX] Landlord Seeking Advice: Tenant Trashed Property, Owes Rent, and Violated Lease - What Are My Options?

I'm a landlord facing a nightmarish situation with a recently evicted tenant, and I need advice on how to proceed. Here's what happened:

  1. Tenant lost his job and didn't pay rent for 3 months.
  2. I went through the court eviction process to have him vacate the property.
  3. After he left, I discovered extensive damage:
    • Appliances (oven, microwave, fridge) damaged
    • Entire house needs repainting(whole house was painted and given in pristine condition to the tenant)
    • Nails embedded in all the wals in the house
    • Bathrooms extremely dirty
    • Bathroom walls broken and poorly "repaired"
    • Garage floor was used for painting related activities and therefore completely damaged
    • All in all, we estimate that the tenant caused approx 20000$ worth of damage
  4. Lease violations:
    • Undeclared occupants: fiancée, 2 children, 2 parents, and a pet
  5. No forwarding address provided
  6. No indication of intent to pay back rent

Questions:

  1. What are my options for recovering damages and unpaid rent?
  2. How can I ensure this eviction and potential credit impact stays on his record?
  3. What legal steps should I take to protect myself and potentially recoup losses?
  4. Are there any landlord protection services or resources I should look into?
  5. How can I prevent similar situations in the future?

Any advice from experienced landlords, property managers, or legal professionals would be greatly appreciated. This is in Plano, Texas. Thanks in advance!
