Conventional Loan PMI vs FHA Mortgage Insurance on Small Down Payments

The Quick Read: Conventional PMI tends to fit buyers with stronger credit who expect to reach roughly 20% equity and drop the insurance. FHA mortgage insurance tends to fit buyers with thinner credit or tighter ratios who need flexibility more than a short insurance life. Both protect the lender, not you. The better choice usually comes down to your credit profile, how long you plan to stay, and how soon you could remove the insurance.

Side-by-Side

All figures are program guidelines, subject to lender review and full file evaluation. Nothing here is a commitment to lend.

What Each Insurance Type Actually Is

PMI is private mortgage insurance. Per the CFPB, it is something you might be required to buy on a conventional loan with a down payment under 20% of the purchase price. The lender arranges it through a private insurer. It protects the lender if you stop paying.

FHA mortgage insurance does the same job through a government program. It has two parts. There is an upfront premium of 1.75% of the base loan, which is financed into the loan. There is also an annual premium, billed monthly, between 0.15% and 0.75% of the balance. The exact level depends on the term, the loan amount and the LTV.

HUD Mortgagee Letter 2023-05 confirms the 1.75% upfront premium applies to FHA mortgages generally, with a few listed exceptions such as certain older FHA streamline refinances. The same letter lowered the annual premium for newer endorsements. That is history. The current schedule lives in HUD’s handbook, so a Loan Estimate is the document that shows what applies to your file.

Why do conventional loans need this at all? FHFA explains that when Fannie Mae and Freddie Mac buy loans above 80% of the property value, their charters require credit enhancement. Mortgage insurance is the most common form.

When Conventional PMI Is the Better Fit

Conventional is usually the stronger play when three things line up.

Your credit is solid. PMI pricing responds to the credit profile. A stronger score can mean a lighter insurance cost. FHA’s annual premium does not move with your score. So the better your credit, the more conventional tends to pull ahead.

You expect the insurance to come off. PMI has legal exit points. For loans on single-family principal residences, the CFPB says you can ask the servicer to cancel when the balance is scheduled to reach 80% of the home’s original value. That request must be in writing, with a good payment history, no junior liens, and evidence the value has not fallen below the original value. Servicers must end it automatically at 78%, if you are current. Some lenders and servicers allow removal under their own standards too.

You are keeping the loan through the equity climb. Original value is the yardstick, not today’s market. A borrower who puts down 5% and pays on schedule needs time to reach the thresholds. Extra principal payments shorten that. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

A few cautions. Conventional PMI is not always the cheaper path on a very small down payment with modest credit. Lender-paid mortgage insurance, where the lender covers the premium in exchange for a higher interest rate, generally cannot be cancelled by the borrower. It ends on refinance. Ask which version your quote uses.

If you are self-employed and weighing documentation, Lendmire’s piece Self-Employed Mortgage vs. Conventional Loan With Low Down and No PMI covers that angle.

When FHA Mortgage Insurance Is the Better Fit

FHA tends to win when approval flexibility matters more than the insurance life. Across the wholesale programs Lendmire places FHA files with, the common profiles look like this.

Credit is thinner. The wholesale programs Lendmire works with start at a 580 decision score, with 3.5% minimum investment and financing up to 96.5%. Some conventional programs set a higher floor. HUD also has a 500–579 tier with a 10% minimum investment, but the network does not reach below 580.

Ratios are tight. The base pair is 31/43 (housing to total debt). Documented compensating factors can stretch that to 40/50 at the top tier. The automated finding governs most files. Conventional programs weigh ratios differently, and a file that struggles there may land differently under FHA.

Help is coming from others. A non-occupant co-borrower is allowed. Seller or interested-party contributions are permitted up to 6% of the price. Gift funds and seller help can matter on a small down payment, and the details vary by program, so the lender’s guidelines control.

Past credit events. HUD sets waiting periods: two years from a Chapter 7 discharge and three years from a foreclosure. Those are HUD rules, not network promises.

Now the catch. On a thirty-year loan above 90% LTV, the annual premium lasts for the full term. At or below 90% LTV, it ends after eleven years. A 3.5% down payment lands in the first group. FHA’s legal exit is not a request at 80%. Many FHA borrowers plan a later refinance instead. A refinance out of FHA with under 20% equity can bring conventional PMI back, so the exit is not free of insurance either. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

The FHA Streamline, which refinances an existing FHA loan without an appraisal, keeps the premium going. If you are already in an FHA loan, Lendmire’s article Conventional Cash-Out vs FHA Cash-Out for Dropping FHA Mortgage Insurance walks through that path.

Occupancy is the other limit. FHA is for a principal residence, one to four units. A second home or rental does not fit this lane, so occupancy decides the leverage.

Holding Period Is the Tiebreaker

Credit and time do most of the deciding. Walk through three buyer sketches, described in plain terms.

Strong credit, staying put. Conventional with PMI usually looks better. The insurance reflects the credit, and it can come off at the equity thresholds.

Fair credit, staying many years. This is a genuine toss-up. FHA’s insurance runs the term at 3.5% down, while conventional PMI may price higher for weaker credit but can still be removed. Run both quotes side by side before choosing. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.

Fair credit, likely to sell or refinance within several years. FHA’s long insurance life matters less if you are gone before it bites. The financed upfront premium and flexible qualification may carry more weight.

Rates and monthly figures change by day and by file, so this article does not model them. The Loan Estimate does. Compare the insurance lines, the upfront charge, and the interest rate together, not one in isolation.

Key Terms Defined

PMI: Private mortgage insurance on a conventional loan, arranged through a private insurer, protecting the lender.

UFMIP: The FHA upfront mortgage insurance premium, 1.75% of the base loan, which can be financed.

Annual MIP: The FHA yearly premium, billed monthly, set by term, loan amount and LTV.

LTV: Loan-to-value, the loan balance as a percentage of the home’s value.

LPMI: Lender-paid mortgage insurance, where the lender covers the premium and the borrower typically accepts a higher interest rate.

Original value: The lesser of price or appraised value at purchase, which drives PMI cancellation dates.

Common Mix-Ups

• PMI does not protect you. It protects the lender.
• Twenty percent down is the usual trigger, not a legal wall. Some programs reduce coverage at higher leverage.
• PMI does not vanish on its own at 80%. You request it then. Automatic termination comes at 78%, if you are current.
• FHA premiums are not cancelled the way PMI is. They follow HUD’s schedule.
• A veteran has another path.

What to Ask Your Loan Officer

1. Which insurance type is on this quote, borrower-paid or lender-paid?

2. When can the insurance end, and what do I have to do?

3. What is the upfront charge, and is it financed?

4. How does my credit score change the insurance cost under each option?

5. What happens to the insurance if I refinance later?

Ask for both versions on the same Loan Estimate basis so the comparison is clean.

If you are buying a home and want to see whether an FHA loan program fits your file, Lendmire can help you compare the options and what each one asks of the file. Program figures are subject to lender guidelines and full file review, and nothing here is a commitment to lend.
