It's my understanding, depending on the state, a renter could take steps to procure the property through being clever* and living there a long time, while taking additional steps to gain a legal claim. Either they have to pay certain bills, improve the property, or get involved in the home owners association. Are there any situations where they can claim the property outside of convincing the landlord to let them pay the property taxes? What about states that allow withholding of rent until the landlord repairs the unity?
I'm specifically looking for edge cases where a dispute could arise between a landlord and tenant that gets dragged out for years. It would be clearly be much easier to just find property no one owns as a result of something like the 2008 financial crisis, where the home owner goes bankrupt and the mortgage company.
*such as, the landlord violating some clause in the lease, and him starting legal proceedings over that.
