What Is PMI and How to Avoid It on a Conventional Loan

Private mortgage insurance (PMI) is one of the most misunderstood costs in homebuying. Some buyers think it protects them. It does not — it protects the lender. Some think it lasts forever. It does not — but only if you are on a conventional loan. And many buyers pay it without knowing there were strategies available to reduce or avoid it entirely.

Here is what PMI actually is, what it costs, and the most practical approaches to avoiding or removing it.

What PMI Is and Why It Exists

Private mortgage insurance is required on conventional loans when the borrower puts less than 20% down. From the lender's perspective, a loan at 95% LTV carries more default risk than a loan at 80% LTV — PMI compensates for that additional risk.

If you default on the loan, PMI pays the lender a portion of the loss. It does nothing for you as the borrower. You pay the premium, the lender gets the protection. This is why minimizing or eliminating PMI is in your interest.

What PMI Costs

PMI rates vary based on credit score, loan-to-value ratio, and the specific PMI provider. Typical ranges:

• 95% LTV (5% down), 760+ credit: approximately 0.5–0.7% of the loan amount annually
• 95% LTV, 700–719 credit: approximately 1.0–1.3% annually
• 90% LTV (10% down), 760+ credit: approximately 0.3–0.5% annually
• 97% LTV (3% down), 740+ credit: approximately 0.6–0.9% annually

On a $380,000 loan at 5% down with a 720 credit score, PMI might run $300–$400/month. That is a meaningful cost — but it is not permanent on a conventional loan.

When PMI Cancels on a Conventional Loan

This is the critical distinction between conventional PMI and FHA mortgage insurance premium (MIP). On a conventional loan:

• Automatic cancellation: PMI must be cancelled automatically when your loan balance reaches 78% of the original purchase price (not current value), based on your scheduled amortization. You do not have to request this — the lender is required to cancel it.
• Requested cancellation at 80% LTV: You can request PMI removal when your balance reaches 80% of the original purchase price, provided you have a good payment history and the property has not declined in value.
• Cancellation based on appreciation: If your home appreciates and you reach 80% LTV based on a new appraisal (typically after 2 years of ownership), you can request PMI removal. The lender may require an appraisal at your expense.

FHA MIP, by contrast, is required for the life of the loan if you put less than 10% down — it never automatically cancels. To get rid of FHA MIP, you must refinance into a conventional loan.

Strategies to Avoid PMI

If you want to avoid PMI entirely from day one, there are a few legitimate paths:

• Put 20% down. The straightforward route — 20% LTV means no PMI requirement. In Chester County where median prices are elevated, this is a significant cash commitment, but it eliminates PMI completely.
• Lender-paid PMI (LPMI). The lender pays the PMI premium in exchange for a higher interest rate. You have no monthly PMI line item, but the cost is built into a higher rate for the life of the loan. This works well if you plan to refinance within a few years — you avoid PMI without the rate increase persisting long-term.
• Piggyback loan (80/10/10). You take a first mortgage at 80% LTV (no PMI threshold), a second mortgage for 10%, and put 10% down. The second mortgage typically carries a higher rate than the first, but the blended cost is sometimes lower than PMI. This structure has become less common but is still available through some lenders.
• VA loan if eligible. VA loans have no PMI, ever — one of their core benefits. If you have VA eligibility, this is almost always the better path versus a conventional loan with PMI.

PMI vs. FHA MIP: The Long-Term Math

A common mistake: choosing FHA over conventional because the rate looks marginally better without factoring in lifetime MIP cost. On a $350,000 loan at 3.5% down, FHA MIP at 0.55% annually is roughly $160/month. Over 30 years with no refinance, that is $57,600 in mortgage insurance premiums — for a loan where the mortgage insurance never cancels.

On a conventional loan with 5% down and a 720 credit score, PMI might run $280/month — more than FHA initially. But when your balance reaches 80% LTV (typically around year 9 on a 30-year loan at normal amortization), PMI cancels. Total PMI paid: roughly $30,000. Conventional wins significantly in this scenario.

The math changes at lower credit scores and higher LTVs, which is why you need to model both scenarios for your specific profile. A free quote from Zurn Mortgages shows you side-by-side conventional and FHA costs including PMI and MIP so you can see the real numbers.
