How Mortgage Insurance Works for Low-Down-Payment Loans

Quick answer

Mortgage insurance (MI) is a lender-protection layer that makes low-down-payment homebuying possible. If you put down less than 20%, most conventional lenders require PMI; government-backed loans use different structures (FHA MIP or a VA funding fee). MI raises your monthly cost but can often be removed once you build enough equity or refinance. (See Consumer Financial Protection Bureau and HUD for program details.)

Why MI exists and what it protects

Lenders price and underwrite loans based on risk. A smaller down payment means less borrower equity and higher risk the lender won’t recover full value if the borrower defaults. MI transfers that loss risk from the lender (or investor) to an insurance provider or a government program so lenders can offer mortgages with lower down payments. This expands access to homeownership—especially for first-time buyers—but it costs money.

Types of mortgage insurance and the main differences

• Private Mortgage Insurance (PMI): Used with conventional loans (Fannie Mae- or Freddie Mac-eligible). PMI is typically charged when the initial down payment is less than 20% and varies with credit score, loan amount, and LTV. See CFPB guidance on PMI for consumer protections.

• FHA mortgage insurance (MIP or UFMIP for the upfront portion): FHA loans require an upfront mortgage insurance premium (UFMIP) and an annual MIP paid monthly. Rules on how long MIP lasts depend on loan origination date, term, and initial LTV. For most FHA loans originated on or after June 3, 2013, if the initial LTV is greater than 90% the annual MIP remains for the life of the loan; if initial LTV is 90% or less, MIP generally terminates after 11 years. See HUD/FHA guidance for exact details.

• VA funding fee: VA loans do not have ongoing MI. Instead, eligible veterans generally pay a one-time funding fee (or it can be financed into the loan). The exact fee percentage depends on service type, down payment amount, and whether it’s the borrower’s first use of the VA benefit. See VA.gov for current tables.

• Alternatives and variations: Lender-paid mortgage insurance (LPMI) where the lender pays the premium and charges a slightly higher interest rate; single-premium MI where the borrower pays a lump sum at closing; and borrower-paid monthly PMI. Each has trade-offs in cost, tax treatment, and ability to cancel.

How costs are calculated (what affects your MI rate)

MI is not a flat fee. Common drivers include:

• Loan-to-value (LTV): higher LTVs = higher premiums.
• Credit score: lower credit scores raise rates.
• Loan amount and loan program: jumbo loans, term length, and whether the loan is conventional or government-backed change pricing.
• Coverage type and insurer: private mortgage insurers use different rating models.

Typical PMI ranges that borrowers often see are about 0.3% to 1.5% of the original loan amount annually for conventional loans; FHA charges an upfront UFMIP (commonly 1.75% of loan amount) plus an annual MIP that varies by LTV and term. Exact numbers change and should be quoted by your lender. (Consumer Financial Protection Bureau; HUD/FHA.)

How you pay MI

• Monthly: most borrower-paid PMI is added to the monthly mortgage payment.
• Upfront: FHA UFMIP is paid at closing or rolled into the loan balance; single-premium PMI is another upfront option.
• Lender-paid: the lender covers the premium but typically increases the mortgage rate—meaning you indirectly pay over the life of the loan.

Each method affects cash flow, long-term interest paid, and the path to removing MI.

When and how MI can be removed

Rules differ by program:

Conventional PMI (Homeowners Protection Act/HPA):

• Request cancellation: once you reach 20% equity (based on the original purchase price or as established in your contract), you can formally request your lender cancel PMI. The lender may require evidence (appraisal) and you must be current on payments.
• Automatic termination: the lender must automatically cancel PMI when the outstanding principal balance reaches 78% of the original value (assuming you’re current on payments), per federal law (HPA).

FHA MIP:

• For FHA loans originated on or after June 3, 2013: if the original LTV was greater than 90%, annual MIP generally remains for the life of the loan; if original LTV was 90% or less, annual MIP typically stops after 11 years. (HUD/FHA official guidance.)
• Refinancing to a conventional loan after accruing 20% equity is a common route to removing FHA MIP.

VA loans:

• No ongoing MI. If you paid a funding fee, it remains part of the loan unless you refinance or pay it off.

Pro tip from practice: I frequently see borrowers miss the request step. If you’ve reached 20% equity, contact your servicer with a written cancellation request and confirm if they require an appraisal. Keep copies of payment histories and communications.

Common strategies to avoid or reduce MI

• Save a larger down payment: 20% eliminates borrower-paid PMI on a conventional loan.
• Shop lenders and compare PMI pricing: different lenders may offer lower PMI or different options like lender-paid MI that suit your cash-flow needs.
• Consider a piggyback loan (80/10/10), but be cautious: second mortgages increase overall leverage and cost.
• Improve your credit score before applying: a higher score can materially reduce PMI rates.
• Refinance once you have 20% equity: if your home has appreciated or you’ve paid down principal, refinancing to a conventional loan without PMI can lower total monthly costs. See mortgage refinancing basics here: https://finhelp.io/glossary/mortgage-refinancing/.

Real-world example (illustrative)

Purchase price: $300,000
Down payment: 5% ($15,000)
Loan amount: $285,000
If PMI is 1.0% annually: Annual PMI ≈ $2,850 or ~$238/month on top of principal/interest, taxes, insurance. Over time, as you pay down the loan and if the home appreciates, you might request PMI cancellation or refinance. In my experience working with first-time buyers, paying PMI for a few years was a lower cost than renting while saving 20% down—but every situation is different.

Common mistakes and misconceptions

• MI protects the lender, not the homeowner. Homeowners insurance protects property and liability; MI protects mortgage investors.
• PMI can’t be removed: False. Conventional PMI can often be canceled or will terminate automatically under federal rules.
• FHA MIP is always temporary: Not necessarily—FHA loans with high LTVs often carry MIP for the life of the loan unless refinanced.
• Lender-paid MI always saves money: It depends. LPMI raises your rate and might cost more over time if you plan to stay long-term, but it lowers initial monthly payments.

Tax considerations (as of 2025)

The tax treatment of mortgage insurance has changed over time. Private mortgage insurance premiums were once deductible under specific income limits but that deduction has not been permanently extended. As of 2025, PMI premiums are generally not deductible for most taxpayers—confirm current law and consult IRS guidance or a tax professional for your situation. See IRS.gov for the latest tax rules.

Who should consider a low-down-payment loan with MI?

• First-time buyers with limited savings comparing the cost of renting versus owning.
• Buyers who can afford monthly MI and expect income or home value to rise enough to reach 20% equity within a few years.
• Borrowers who prioritize keeping cash reserves for emergencies rather than depleting them for a larger down payment.

What I often tell clients: run the numbers both ways—what’s the monthly cost including MI versus waiting to save more—and include closing costs, potential appreciation, and your expected time in the home.

Checklist: Removing PMI or MIP

1. Track your balance and LTV. Use original purchase price or updated appraisal as required by your servicer.
2. Keep current on payments—cancellation requires no delinquencies for some programs.
3. Contact your mortgage servicer when you approach 20% equity and ask for the exact documentation they require.
4. Consider refinancing if appraisal values increase or you’ve paid down principal to reach 20%.
5. If FHA MIP applies and you can refinance into a conventional loan without MI, compare costs and closing fees carefully.

Closing thoughts and professional disclaimer

Mortgage insurance is often the bridge that makes homeownership possible for buyers with limited savings. In my 15+ years advising clients, I’ve found the right decision depends on how long you expect to stay in the home, your cash reserves, credit profile, and local home-price trends. Use the cancellation rules to your advantage, shop lenders for PMI pricing or LPMI options, and consider refinancing when equity permits.
