The threat of cybersecurity is extremey serious and I can tell you hacker is always two step ahead of the good guy.However there still need to capture all transaction in one cloud-like that saves the whole database and AI or LLM model could create faster title insurance issuance.

Like it was stated before the neighbors could be an issue or there might be something regulatory on the horizon that is a threat. 

They set their own (very expensive) prices for repairs, tell you very little and then get moody when you question why they're throwing enormous invoices at you on a very regular occurrence.Back to the threat of the lien - if they ignored me querying their invoices and went ahead and applied a mechanics lien to my property, how do I contest it (or return the favor to them), when or how will I get to hear about it, do they have to re-apply it every year to stop me selling the property (which I do not intend to do for another few decades, if ever), can they put extra costs & interest on the lien and can they apply to the courts, at any time, for a foreclosure to settle what they say I owe?

But how come it seems to be so impossible to rent by the room without a hanging threat of HOA lien over your head??

Since my lawyer says the contract is enforcible, the threat of litigation is at least leverage.

This is a double threat. 

I can understand your anger and frustration, but this is the time for a methodical, rational approach and follow each step of the law...not rants, threats and anger.

This particular PMC has a very aggressive termination fee and one of the partners in the company is an attorney and they intimidate owners looking to terminate with threats of property liens and lawsuits.Who still wants a short contract?

We have a thriving medical and cyber security industry with a lot of big name Defense Contractors in the area (Lockheed Martin, General Dynamics, etc.)Stop ignoring real estate investors here, you're losing money if you continue to do so!

Do I just ignore the threat and hope to get more information next time when he inevitably calls again (since clearly if I don't know who he is I can't remove him from my list)?
