Most discussion of PMI removal focuses on equity — hitting 80% or 78% loan-to-value. But there's a separate, lesser-known trigger built into federal law that has nothing to do with how much your home is worth: the loan midpoint.
What the Midpoint Rule Says
Under the Homeowners Protection Act, your servicer must terminate PMI when your loan reaches the midpoint of its amortization term — and you're current on payments. For a standard 30-year loan, that midpoint is the start of year 16. For a 15-year loan, it's year eight.
This applies regardless of your LTV. Even if your balance hasn't reached 78% of the original value, PMI must come off at the midpoint. It's a hard backstop.
The midpoint rule exists for a reason: on some loans, slow early paydown means the balance wouldn't reach 78% until very late in the term. Without the midpoint backstop, those borrowers could pay PMI for decades.
Who the Midpoint Rule Actually Helps
For a typical borrower, the midpoint is a long way off and the equity-based triggers arrive first. But the midpoint rule becomes the deciding factor in specific situations:
- Loans that have been modified, extending the term or re-amortizing the balance.
- Loans where the property has lost value, so the 80% and 78% equity triggers stay out of reach.
- Interest-heavy structures where principal builds very slowly in the early years.
Why You Shouldn't Wait for It
The midpoint is the slowest possible way to lose PMI. If your home has appreciated or you've paid down principal, you'll almost always reach the 80% equity threshold — and the right to request cancellation — many years before the midpoint arrives.
Think of the midpoint as a guarantee that PMI cannot last forever, not as a target to aim for. Reaching 80% LTV and requesting cancellation is nearly always the faster route.
The Bottom Line
The midpoint rule is a useful safety net, especially on modified or underwater loans. But for most homeowners, it's a backstop you'll never need — because you'll qualify to cancel PMI on equity long before then.
