What Is PMI? Mortgage Insurance Explained in Plain English
This is a subtitle for your new post
What mortgage insurance actually is
If you’ve been told you’ll need “PMI” on your loan, your first reaction was probably some version of why am I paying to insure the bank? Fair question. I hear it every week from buyers across Franklin, Thompson’s Station, Spring Hill, and Columbia — so here’s the honest answer, without the jargon.
Mortgage insurance is a monthly premium added to your payment when you put down less than 20% on a home. It protects the lender — not you — if the loan ever defaults.
That sounds like a raw deal until you see what it buys you: the ability to purchase a home with 3%, 3.5%, or 5% down instead of waiting years to save 20%. In a market like Middle Tennessee, where home values have climbed steadily, buying sooner with mortgage insurance has often cost families far less than renting while home prices rose out from under them.
So the right way to think about mortgage insurance isn’t “a fee I’m stuck with.” It’s the price of admission for buying years earlier — and in most cases, it’s temporary.
What it costs
On a conventional loan, private mortgage insurance (PMI) typically runs somewhere between 0.25% and 0.9% of your loan amount per year, split into monthly installments. On a $400,000 loan, that’s roughly $85 to $290 a month depending on your down payment and credit score.
Two things drive your PMI price:
Your down payment. The more you put down, the cheaper PMI gets. A buyer at 15% down pays far less than a buyer at 3% down.
Your credit score. PMI is credit-sensitive. Strong credit can cut your premium roughly in half compared to a lower score on the same loan.
You can see how PMI changes your full payment using my mortgage calculator — it estimates mortgage insurance automatically based on your loan program and down payment.
PMI vs. FHA MIP: they are not the same thing
This is where most online explanations fall short. “Mortgage insurance” means two very different things depending on your loan program.
Conventional loans have PMI (private mortgage insurance). No upfront charge on most structures, credit-sensitive pricing, and — this is the important part — it goes away on its own.
FHA loans have MIP (mortgage insurance premium). FHA charges 1.75% of the loan amount upfront (almost always rolled into the loan) plus an annual premium paid monthly. MIP is the same price whether your credit score is 640 or 800. And with less than 10% down, it stays for the life of the loan.
Here’s the practical takeaway I give clients: if your credit is strong, conventional with PMI usually wins. If your credit is still recovering, FHA’s flat pricing often makes it the cheaper path — and we plan from day one to refinance out of MIP once you’ve built equity.
VA loans, by the way, have no monthly mortgage insurance at all. If you’ve served, that benefit alone can save you hundreds a month. USDA loans use a smaller annual fee (0.35%) that works differently again.
When mortgage insurance goes away
Conventional PMI: you can request cancellation once you reach 20% equity — through paying down the loan, home appreciation, or both. It cancels automatically once your balance hits 78% of the home’s original value. Extra payments get you there faster. So does appreciation — and Williamson and Maury County homeowners have seen plenty of that.
FHA MIP: with 10% or more down, MIP drops off after 11 years. With less than 10% down, MIP lasts the life of the loan. The exit is refinancing into a conventional loan once you have 20% equity — a move I help clients time correctly.
In an appreciating market, many of my clients reach 20% equity years before they expected. It’s worth checking annually; removing PMI is often as simple as a phone call and an appraisal.
Should you just wait until you have 20% down?
Sometimes — but less often than you’d think. Run the numbers both ways: PMI on a typical first-time buyer loan might cost $150–250/month for a few years. Waiting three more years to save 20% means three more years of rent, and buying at whatever prices look like then.
For most buyers I work with in Middle Tennessee, the math favors buying sooner with mortgage insurance and a plan to remove it. But not always — it depends on your savings, your credit, and your timeline. That’s a fifteen-minute conversation, not a guess.
The bottom line
Mortgage insurance isn’t a penalty — it’s a tool. Used with a plan (the right program, the right down payment, a clear path to removal), it gets families into homes years sooner for a modest, temporary cost. Used without a plan, it’s just money out the door every month.
My job is making sure you’re in the first group.
