What is mortgage insurance and when is it required?

Private mortgage insurance, or PMI, is a policy that conventional mortgage lenders require from borrowers who put down less than 20% of the home’s value. Despite the name, the insurance protects the lender—not the borrower—if payments stop and the home enters foreclosure. The borrower pays the premiums, often monthly, but the coverage reduces the lender’s financial risk. This is distinct from mortgage protection insurance, which pays off the loan if the borrower dies or becomes disabled.

Mortgage insurance becomes necessary in two common scenarios:

• Conventional loans – Any time the loan-to-value (LTV) ratio exceeds 80%, meaning the down payment is under 20%. PMI is then added to the monthly payment until equity reaches 20%.
• Government-backed loans – FHA loans always require mortgage insurance premiums (MIP), regardless of down payment size. USDA loans similarly require a guarantee fee, and VA loans impose a funding fee, which serves a comparable purpose for lenders.

Borrowers who make a smaller down payment should expect to pay some form of mortgage insurance, though the exact requirement depends on the loan program.

Different loan programs use different names and structures for their mortgage insurance:

While each serves the same purpose—shielding the lender from default risk—the cost, duration, and cancellation rules differ. Understanding the differences helps borrowers choose the loan that best matches their financial plan.

Lenders using Chatref can turn their own underwriting guides, product sheets, and FAQs into a reliable knowledge base. When a borrower asks “what is PMI?” or “can I cancel my mortgage insurance?”, Chatref’s AI agents respond with answers grounded in the lender’s specific policies—no internet search, no guesswork. This keeps answers consistent, reduces the volume of repetitive calls, and gives loan officers time back for high-value conversations.

How do I remove private mortgage insurance?

On conventional loans, you can typically request PMI cancellation once your loan balance drops to 80% of the original property value, based on your payment schedule. It should automatically terminate when the balance reaches 78%. Some lenders require a formal appraisal and a history of on-time payments. Contact your servicer for your specific requirements.

What is the cost of mortgage insurance?

PMI for conventional loans generally ranges from 0.3% to 1.5% of the original loan amount per year, paid monthly. Factors include credit score, LTV ratio, and loan term. FHA MIP includes an upfront premium (1.75% of the loan) plus an annual premium that varies by loan parameters. Use your lender’s PMI calculator for a precise estimate.

Is mortgage insurance tax deductible?

The deductibility of mortgage insurance premiums has expired for tax years after 2021. For prior years, it was an itemizable deduction subject to income limits. Always consult a tax professional for current rules and your personal situation.
