Let’s say they report it and I dispute it as “not my debt, please confirm”.

Thank you for your reply ~ I do consider this a LessonLearned; but still need resolution to the current situation :/

For example, if there is some dispute about whether someone has an interest in a property, they can sign over their rights without ever establishing what those rights are if any at all to clear up the issue.

Both purchase price taxes and expenses could be disputed as higher or lower though I think they are pretty reasonable.

The vast majority of lawsuits against Landlords are for wrongful eviction, security deposit disputes, and Fair Housing Violations.

They may have thought I was clueless to market rent, but they gave me notice and I had got rid of a tenant with little chance they would dispute anything.

You seem to want to dispute that, but home prices have approximately quintupled since 1980 in Illinois, where the initial example was setA property that quintupled since 1980 would not have such a low price as the Peoria example.

Best option is to dispute the appraisal.

If not, Im not sure how you could resolve a dispute short of suing them.
