Mortgage trouble does not always begin with missed payments. In many cases, it begins with paperwork, account handling, and communication breakdowns inside the servicing process. A homeowner can pay on time, keep insurance in place, and still end up facing late fees, escrow shortages, default notices, or even foreclosure pressure because a servicer made an avoidable error.

That does not mean most homeowners are in crisis, but it does show that many loans remain vulnerable when servicing problems and payment stress overlap (MBA National Delinquency Survey Q1 2025).
One of the most damaging servicing mistakes is also one of the simplest: the servicer receives a payment but does not apply it correctly.
This can happen in several ways:
