I like my tenants, bad or good (that comes with the territory), but to hide yourself from them, is fighting a hopeless battle, because at some time or another, they will eventually know who you are, via court, summons, whatever. 

Even when the law seems clear that a lien should be wiped out, you'll still find yourself in fights with city/county entities claiming you owe them for something.

That's going to be crucial to compare to the current condition of the property, especially if there are any discrepancies they want to fight you on, and even more important if this ends up in court, not saying it will, but the condition report is key.

Why does your local fire department stock a couple million dollars worth of fire fighting apparatus?

If you didn't take the course, you don't have a dog in the fight.

If the tenants were told in advance that the house would be listed - or may be listed - then they are wrong to fight it.I agree our primary responsibility is to the Owner, but we can't violate a legal contract or the law, which is why I bring up the right to quiet enjoyment.

The best way to fight those I have done are argue their valuation and offer to buy the asset well above their appraisal price or get an appraisal of your own. 

Not assessed probably means not incurred, subject to fights over semantics.Why do I not expect it enforced?

give them appropriate notice, according to state laws, that you are raising rent to market, and if they don't want to pay market they will have to move. you may even consider giving them an extra 30 days if you wanna be mr. nice guy.be prepared for some hard feelings, as after 12 years they will feel as though they have a right to be there. the truth is they don't, but in the interest of getting them out without a fight, you may consider giving them a "reward" for being such long term tenants, such as security deposit in cash the day they move out, or offer to pay for a moving truck, or something like that, but I would only offer if you expect getting them out to be a battle, since it would be cheaper then eviction.

This means my window to provide written notice and secure inspection is more defensible.I will not be going down without a fight!
