My father paid interest on the difference over the monthly amount. As specifically stated in what you referenced. But thank you for calling me ignorant.

I’m not actually surprised that, even though the rule seems to clearly state the opposite of what you said, that courts may find in favor of the tenant, because in my experience, the tenant had far more rights than the landlord. And my tenants had no compunction with doing thousands of dollars of damage to my house and then moving out. In fact, I stopped renting, because of so many bad experiences with tenants. The money just isn’t worth it.
