If it matters I see the problem is the manager. If he is an agent managing the property find the statute and bring it to the attention of the property owner. The property owner may become angry with the manager but the manager is basically breaking the law in the landowner's name.
Then again you might talk this over with the manager first. One thing I see a problem is involving your father who is the property owner without his support. Of course this is a health issue, of which you are distinctly a party in interest.
Inherent in the Title here is that I am making the same suggestions to you that I would make to a suitor. A suitor has a better understanding of trusts, contracts and relationships - synonyms actually. The Lesson Plan is comprised of:
1) True Name/Identity
2) (administrative) Record Forming
3) Redeeming Lawful Money
In other words, it is the same problem, the same solutions from the perspective of being a suitor. More like understanding one's authority to abate a nuisance, having the process published, and being able to do so in the Image and Likeness of God will enhance the chances of success. Sometimes we perceive an attack where there is none and in hindsight find we could have avoided the entire war or battle.
