Oh man, landlord is SOOOOO wrong! First, landlord is responsible for the damage the painter caused, because the painter was landlord's agent & people are responsible for their agent's actions. Second, landlord's rent hike is pretty obviously retaliatory, since he raised the rent AFTER you complained about the damages. You get to sue out his eyeballs. Here are some choice provisions of the VA landlord tenant act. You'll have to read the laws to see which one apply to residential leases and which to mobile home parks.
===========================================
§ 55-248.38
Landlord and tenant remedies for abuse of access
If the tenant refuses to allow lawful access, the landlord may obtain injunctive relief to compel access, or terminate the rental agreement. In either case, the landlord may recover actual damages and reasonable attorney's fees. If the landlord makes an unlawful entry or a lawful entry in an unreasonable manner or makes repeated demands for entry otherwise lawful but which have the effect of unreasonably harassing the tenant, the tenant may obtain injunctive relief to prevent the recurrence of the conduct, or terminate the rental agreement. In either case, the tenant may recover actual damages and reasonable attorney's fees.
============================================
§ 55-248.51
Penalties for violation of chapter
If the landlord acts in willful violation of §§ 55-248.43, 55-248.45, 55-248.47 or § 55-248.50 or if the landlord fails to provide a written, dated lease, the tenant is entitled to recover from the landlord an amount equal to the greater of either the tenant's monthly rental payment at the time of the violation, or actual damages and reasonable attorney's fees.
§ 55-248.39
Retaliatory conduct prohibited
(a) Except as provided in this section, or as otherwise provided by law, a landlord may not retaliate by increasing rent or decreasing services or by bringing or threatening to bring an action for possession or by causing a termination of the rental agreement pursuant to § 55-222 or § 55-248.37 after he has knowledge that: (i) the tenant has complained to a governmental agency charged with responsibility for enforcement of a building or housing code of a violation applicable to the premises materially affecting health or safety; or (ii) the tenant has made a complaint to or filed a suit against the landlord for a violation of any provision of this chapter; or (iii) the tenant has organized or become a member of a tenants' organization; or (iv) the tenant has testified in a court proceeding against the landlord. However, the provisions of this subsection shall not be construed to prevent the landlord from increasing rents to that charged on similar market rentals nor decreasing services that shall apply equally to all tenants.
(b) If the landlord acts in violation of this section, the tenant is entitled to the applicable remedies provided for in this chapter, including recovery of actual damages, and may assert such retaliation as a defense in any action against him for possession. The burden of proving retaliatory intent shall be on the tenant.
(c) Notwithstanding subsections (a) and (b) of this section, a landlord may terminate the rental agreement pursuant to § 55-222 or § 55-248.37 and bring an action for possession if:
(1) Violation of the applicable building or housing code was caused primarily by lack of reasonable care by the tenant or a member of his household or a person on the premises with his consent; or
(2) The tenant is in default in rent; or
(3) Compliance with the applicable building or housing code requires alteration, remodeling or demolition which would effectively deprive the tenant of use of the dwelling unit; or
(4) The tenant is in default of a provision of the rental agreement materially affecting the health and safety of himself or others. The maintenance of the action provided herein does not release the landlord from liability under § 55-248.11.
(d) The landlord may also terminate the rental agreement pursuant to § 55-222 or § 55-248.37 for any other reason not prohibited by law unless the court finds that the primary reason for the termination was retaliation.
=======================================
§ 55-248.50
Retaliatory conduct prohibited
A. Except as provided in this section, or as otherwise provided by law, a landlord shall not retaliate by selectively increasing rent or decreasing services or by bringing or threatening to bring an action for possession after he has knowledge that: (i) the tenant has complained to a governmental agency charged with responsibility for enforcement of a building or housing code of a violation applicable to the premises materially affecting health or safety; (ii) the tenant has made a complaint to or filed a suit against the landlord for a violation of any provision of this chapter; (iii) the tenant has organized or become a member of a tenants' organization; or (iv) the tenant has testified in a court proceeding against the landlord.
B. The landlord shall be deemed to have knowledge of a fact if he has actual knowledge of it; he has received a notice or notification of it; or, from all the facts and circumstances known to him at the time in question, he has reason to know that it exists.
C. Notwithstanding the provisions of subsections A and B of this section, a landlord may terminate the rental agreement pursuant to subsection A of § 55-248.46 and bring an action for possession if:
1. Violation of the applicable building and housing code was caused by lack of reasonable care by the tenant or a member of his household or a person on the premises with his consent;
