When homebuyers purchase a property with a down payment below 20%, lenders almost universally require an additional layer of financial protection: Private Mortgage Insurance, commonly referred to as PMI. For many homeowners, PMI represents a monthly cost they know they're paying but don't fully understand — including how it connects directly to their home equity and what they can do to eliminate it.
This article demystifies PMI: what it is, why it exists, how much it costs, and most importantly, how building your equity positions you to remove it from your monthly budget.
What Is Private Mortgage Insurance?
Private mortgage insurance is a policy that mortgage lenders require when a borrower's down payment on a conventional loan is less than 20% of the purchase price. The insurance is issued by a private insurance company (not a government agency) and compensates the lender for a portion of their financial exposure if the borrower stops making payments and the property must go through foreclosure.
From the lender's perspective, a borrower who has invested less than 20% of the home's value has less financial stake in the property, which statistically correlates with a higher probability of default during financial hardship. PMI offsets that elevated risk, enabling lenders to extend financing to buyers who haven't yet accumulated a full 20% down payment.
How Much Does PMI Cost?
PMI costs vary based on your loan size, credit score, down payment amount, and the insurance provider. As a general range, annual PMI premiums typically fall between 0.5% and 1.5% of the original loan amount, billed monthly as part of your mortgage payment.
For example, on a $350,000 loan at a PMI rate of 0.8%, the annual premium is $2,800, which translates to approximately $233 added to your monthly payment. Over several years, that total becomes significant — which is precisely why eliminating PMI as soon as you're eligible can produce meaningful savings.
The Direct Connection Between PMI and Home Equity
PMI and home equity are inseparably linked. PMI is triggered when your equity is below 20% of the home's value — meaning your loan-to-value ratio (LTV) exceeds 80%. As you build equity through principal payments, extra contributions, or market appreciation, your LTV decreases. Once it reaches the 80% threshold, you may be eligible to request PMI removal.
This relationship means that every strategy for building home equity faster is also a strategy for eliminating PMI sooner. Larger down payments, accelerated principal payments, and rising property values all work in your favor on both dimensions simultaneously.
- LTV above 80% (Equity below 20%): PMI is active and required on conventional loans. Cancellation cannot be requested yet.
- LTV reaches 80% (Equity at 20%): You may formally request PMI cancellation from your lender. Some lenders require a new appraisal to confirm the current value.
- LTV reaches 78% (Equity at 22%): For conventional loans, federal law requires lenders to automatically cancel PMI once scheduled payments bring the loan to this level — based on the original amortization schedule.
- LTV at 75% or below (Equity at 25%+): Some lenders cancel PMI at this level for loans considered higher risk at origination. Check your original loan documents.
Types of PMI Arrangements
Not all PMI works the same way. There are several structures homeowners may encounter depending on how their loan was originated.
Borrower-Paid PMI (BPMI)
The most common structure. The homeowner pays a monthly premium added to their mortgage payment. This type is cancelable once sufficient equity is established, making it the most flexible arrangement for borrowers focused on building equity.
Lender-Paid PMI (LPMI)
In this arrangement, the lender pays the PMI premium upfront and recoups the cost through a slightly higher interest rate on the loan. While this eliminates the visible monthly PMI line item, the higher rate cannot be removed by building equity — the only way to escape lender-paid PMI is to refinance into a new loan once your equity position qualifies you for conventional financing without PMI.
Single-Premium PMI
The borrower pays the entire PMI premium upfront at closing, either in cash or by rolling it into the loan balance. This eliminates ongoing monthly premiums but requires a larger payment at the outset and does not produce a refund if equity milestones are reached early.
How to Request PMI Cancellation
When your LTV reaches 80% based on your original purchase price or appraised value at origination, you can formally contact your loan servicer to request PMI cancellation. The servicer may require a written request, confirmation that your payment history meets their standards (typically no late payments in recent months), and in some cases, a new appraisal at your expense to verify the home's current market value.
If your home has appreciated significantly, a fresh appraisal might show that your LTV is well below 80% of the current value even if you haven't paid down much principal. This can accelerate your PMI removal timeline considerably in markets with strong price growth.
Government-Backed Loans and Mortgage Insurance
FHA loans carry a different form of mortgage insurance called the Mortgage Insurance Premium (MIP), which functions similarly to PMI but operates under different rules. FHA MIP may be required for the entire life of the loan depending on your down payment and loan origination date, making refinancing into a conventional loan (once sufficient equity exists) an important consideration for FHA borrowers seeking to shed the insurance cost.
